readjust clevis/lower rod length with the sping clipbuttons so that the search coil can be held near thefloor without requiring stooping over.

7. Remove the protective paper from the two blackelbow cup foam pads. Carefully align pads on theinside of the elbow cup, one on each side of thecenter rod, and press firmly into place.

8. Adjust the elbow cup strap so that it is looseenough for you to slide your arm in and out with-out loosening each time you want to set the detec-tor down. The elbow cup strap provides extraleverage and control. However, some prefer not touse it.

9. Install battery as described in the next section,decal facing down, with plastic tab and steel contactsfacing toward inside of battery compartment.

10. It should be noted at this point that the detectormay not work as expected indoors due to the highdegree of metals used in modern construction. It isbest to tune and practice out-of-doors to ensurestable, predictable results. Additionally, freshly-buried targets will not produce the normal depthand discrimination results of targets that have beennaturally lost and settled in the ground. Due to theabnormality caused by digging a hole in the groundmatrix, and the sophistication of the ground rejec-tion circuitry, it may take a number of years forfreshly-buried targets to respond at true depths anddiscrimination accuracy. The best way to deter-mine true detection depth is in real search condi-tions.

Assembly Instructions1. Remove all parts from shipping carton andcheck the assembly page to make sure all parts arepresent.

2. There are rubber washers between clevis/lowerrod and loop ears. Use only nonmetallic washers,fiber bolt, and thumbnut to secure loop/searchcoil to clevis/lower rod.

3. Unlock "S" rod camlock and insert clevis/lower rod into curved "S" rod so that stainlesssteel spring clip buttons line up and lock into oneof the adjustment holes in the curved "S" rod.Turn camlock to secure. The second or thirdadjustment holes are suitable for average sizeadults. Individuals 6' or taller should use the fullyextended position. Individuals well over 6' tallshould purchase the optional Tall Man Rod.

4. Unravel loop cable and wind the cable aroundthe clevis and rod assembly, first revolution overthe top of the rod. Wind cable all the way to thetop of the curved "S" rod, about five revolutions.Use the black cable retainers, one near the loop,and one near the top of the curved "S" rod, to holdthe loop cable in place.

5. Unlock control box rod camlock and insertcurved "S" rod so that stainless steel spring clipbuttons line up and lock into the rod on top of thecontrol box. The "S" rod is designed to curve uptoward the display. However, those who prefer tosweep the loop close to their feet may desire toassemble the "S" rod to curve down toward theground. Turn camlock to secure. Plug loop con-nector into control box, screw lock ring to secure.

6. Grip the instrument by the handle, with your arm inthe elbow cup with strap secure, and sweep the loop/search coil over the floor. If the instrument fit feelsuncomfortable, adjust the elbow cup by removingand repositioning the bolt/thumbnut and installingin one of the optional positions. If necessary,

Rechargeable Battery

A rechargeable battery (green decal) is providedwith your instrument. This battery can be rechargedhundreds of times as long as the battery hasn't beenstored for extended periods of time or overcharged.Full charge can be achieved anytime during thedischarge cycle. When using the QUICK chargersetting use the Charging Hours chart on the follow-ing page for charge time. A full charge will last tento fifteen hours of normal use.

Battery life will vary with temperature, the numberof targets found, and the exact settings used. Sixhours is not unusual for extreme high performancesettings, backlight use, or for batteries that haveexperienced extensive use.

Your charger has a switch on it that selects theQUICK charge, or OVERNIGHT charger options.Always check the position of this switch prior tocharging. Always follow the charge hours on thechart on the following page when the QUICKcharge setting is used. Over-charging with theQUICK charge setting will damage the system.

CAUTIONBattery #802-5211

Using theStandard Battery Holder1. Slide open the battery holder lid (decal side ofbattery holder) by applying gentle upwardpressure on the tab of the door so that it unlocks.Slide the door away from the battery boxexposing the cell positions.

2. Remove any old cells from the holder. Note the(+) and (-) positions of each cell and the (+)and (-) for each position marked inside the cell tray.Install new “AA” cells noting carefully the cor-rect (+) and (-) positions.

If the cells are installed incorrectly, the detectormay require service by an AuthorizedService Center.

3. Slide the door closed so that it snaps securely.

4. Insert the battery holder into the detector so thatthe decal is facing down, with the batteryholder door tab and metal contact points facingtoward the inside of the battery compartment.

Close the battery compartment door and secure thetwo latches on the bottom of the case. Hook thefront of each latch first, then press down on therear.

6. The battery will lose its charge during storage.If stored inserted in your instrument, this loss willbe more noteworthy. It is recommended that thebattery be removed from the instrument duringperiods of storage. It is not advisable to store re-chargeable batteries for long periods of time with-out use. If however, storage is necessary, storewithout a charge (discharged).

7. Do not discharge the battery in devices otherthan your metal detector. Unnecessary dischargingand/or an absolute discharge will reduce battery lifeand may damage the battery. Unlike older recharge-able battery designs, the rechargeable batteryprovided with your detector can be recharged at anytime. Regardless of whether or not it already has apartial charge, memory will not occur.

8. White's has provided the leading edge of re-chargeable battery technology with your instru-ment. Disregard all advice which conflicts with theabove recommendations. Care for batteries pro-vided by other manufacturers, or with other White'smodels, may vary.

Charging 1. There is no harm charg-ing overnight using theOVERNIGHT chargersetting regardless of thebattery's current condition.However, before chargingwith the QUICK chargersetting, determine batterycondition by insertingbattery into the instrumentand turning the instrumentON. If the instrument willnot turn ON, or if voltagetests eight volts or below,charge five hours with theQUICK charge. If the battery voltage tests any othervoltage, refer to the Charging Hours chart above forproper QUICK charge time.

2. To charge, insert the charger plug into the batterypack jack, located near the plastic tab andmetal contact points.

3. Plug the charger into a standard wall outlet.(110 volts for USA models).

4. Again, the QUICK charger setting uses theabove chart for a specific charge time. OVER-NIGHT is designed to charge the battery in as littleas fourteen hours. However, no harm will come tothe system leaving it charging for several days.

5. It is normal for the battery and charger to getwarm during use. However, if either the battery orthe charger gets too hot to hold or deforms due tothe heat, discontinue use and return for testing.

Chapter 2 XLT® Batteries

Battery Life & MemoryVolatile memory temporarily holds any programchanges or settings not yet saved in a CustomProgram. Short-term or volatile memory is retainedso long as a good battery remains in the detector.To recover volatile memory immediately squeezeand release the TRIGGER once the detector isturned ON. If the battery is removed all volatilememory is lost. Long-term memory (programssaved in Custom Programs) is automatically savedfor up to ten years regardless of whether a battery isin the detector or not.

When using fresh batteries, the voltage will initiallycheck somewhere in the 10 to 14 volt area. Unlikestandard batteries, the rechargeable battery voltagewill quickly drop to between 9 and 10 volts andplateau there for most of its life. Once the recharge-able battery voltage drops below this plateau, it willquickly drop below a usable voltage level (eightvolts) and thus require a recharge. Low Battery willautomatically appear on the display when thebattery reaches eight volts.

Like a personal computer, there are times (such aslow battery conditions) when the microprocessor ofa metal detector becomes out of sequence with therest of the circuitry. This is often noted by pecu-liarities in the non-discrimination or pinpointing(TRIGGER squeezed) modes. Symptoms may beblaring or silent non-discriminate or pinpointmodes, depth indication inaccuracies or generalabnormal operation. To correct such difficulties "re-boot" by:

1. Install a good battery.2. Turn ON wait for MAIN MENU to appear.3. Open battery door and remove battery while detector is still ON.4. Wait one minute, re-install battery, turn detector ON, and check for proper function.

Use of maximum backlight may reduce battery lifeby up to 50%, depending on battery type.

Rechargeable batteries gradually deteriorate. Asthey age they do not provide the life-per-chargethey did when new. This is expected, and notgrounds for replacement under warranty. Addition-ally, a damaged initial cell, which is caused byover-charging with the QUICK option, is notreplaced under warranty. Only cell failure throughnormal use, or a defect due to a problem with aWhite's warranted XLT® charger, is covered.

Chapter 3 XLT® Quick Start

Search Fundamentals

The loop/search coil must be in motion (sweep-ing from side-to-side) for this instrument torespond to metal. Practice a smooth sweep of theloop from side-to-side keeping the loop close to theground throughout the swing. Each pass of theloop should take approximately two secondsfrom right to left, two seconds to return from leftto right.

Walk forward slowly. Take small steps no greaterthan half normal strides. Make sure each pass of theloop overlaps the last by at least half the length ofthe loop. Do not lift the loop at the end of eachswing. Keep it close to the ground at all times.

To become comfortable with sweeping the looptakes some practice. Try to loosen up and find acomfortable grip on the handle. Premature fatiguemay result from gripping the handle too tightly,improperly adjusted rod or elbow support, andlimited body movement. Hold the handle loosely.Adjust the rod and elbow support for comfort andkeep the elbow strap loose. Use your arm, shoulderand even your back a little to allow a smooth evensweep of the loop.

Now that you're sweeping the loop smoothly over theground, you will notice that the detector starts makingsounds (beeps). Not all sounds are good targets;some trash targets also make the detector beep.

As the loop is swept over the ground, ignore thedisplay and concentrate on the sounds the detectormakes.

As the loop is passed over metal that is likely trash,the sound will be inconsistent. Trash targets typi-cally produce a shorter, sputter-type sound, that isoften broken or double in nature. Place a steel-popbottlecap on the ground. Pass the loop over itseveral times to become familiar with this sound atdifferent loop sweep speeds. Note that an aluminumtwist-off bottlecap cannot be used as it is a differ-ent type of target. Also note that very old rustybottle caps may start reading as quarters due to theelimination of the iron alloy through deterioration.Once familiar with the sound typical bottle capsproduce, an operator may pass over such targets andcontinue searching without consulting the displayinformation, saving more time for evaluatingpossible good targets.

As the loop passes over metal that is likely a goodtarget, a more consistent and smooth sound will beheard. A good target typically produces a longer,more solid sound. Place a quarter on the ground andsweep the loop over it several times to becomefamiliar with the sound of a good target.

Why Air/Ground Balance?When the display prompts you to, AIR BALANCE byholding the loop at waist level and press ENTER. TheXLT®'s circuits are being prepared for ground balanc-ing by measuring temperature and other variables thataffect electronic circuits. The XLT® "beeps" and youlower the search coil to the distance above the groundthat you will be searching. Press ENTER to have theXLT® "cancel/track out" or GROUND BALANCEthe ground mineralization. The XLT® then automati-cally "tracks out" the varying mineralization as youcontinue to search.

1. V.D.I. Visual Discrimination Indication("target reference number")In the upper left hand-side of the display there is aV.D.I. number that corresponds to the V.D.I.SCALE painted on the top right-hand side of thecontrol box. It also corresponds to the DiscriminateEdit feature allowing you to reject or accept targetsbased on their V.D.I. reference number. There are"+" numbers for non-ferrous (not of iron) targets,and "-" numbers for ferrous (iron) targets. RejectedV.D.I. numbers may not appear if the VISUALDISCRIMINATION feature is ON. Reasonablyconsistent V.D.I. reference numbers (± five digits),in a desirable area of the chart is a vote for diggingthe target.2. Possible Target Identities ("Probable or mostlikely Target")To the right of the V.D.I. number, possible targetidentities will be represented graphically. Thesegraphics are called ICONS. A fairly consistentindication of a desirable target is another vote to digthe target. One or two possible target icons mayappear. There is significance to which icon appearsfirst. The first target to appear is always the mostlikely, the second is another possibility slightly lesslikely than the first.3. SignaGraph™The SignaGraph™ at the bottom of the displayprovides a final vote as to whether or not the targetshould be dug.

A. Sweep the loop over the target several times andlook at the SignaGraph™. The SignaGraph™automatically clears itself (FADE RATE) so that itdoesn't fill the screen with information from pastloop sweeps. An operator has limited time to lookat the SignaGraph™. If you want to look at theinformation again, sweep the loop over the targetseveral more times. The fading of theSignaGraph™ information can be slowed orspeeded (FADE RATE) to operator preference.This is completed in the PRO OPTIONS underDISPLAY. Automatic AVERAGING and/or AC-CUMULATING of SignaGraph™ information isalso available (See PRO OPTIONS).

B. Valuable targets will show up on the positiveside of the graph. The positive area of the chart isthe section located to the right of the zero.

C. Look for consistency. In ideal conditions, coinsand jewelry produce one or two bars to the right ofzero. Trash produces several bars, sometimes onboth sides of zero.

D. In less than ideal conditions, coins may producea wider pattern of bars. Most trash targets produce arecognizably different pattern than valuable targets.

E. One of the most visual benefits of theSignaGraph™ is the ability to show a smearpatternon iron targets that often fool the other methods ofidentification. An iron target will likely showdefinite bars on both the negative and positive sidesof the SignaGraph™, often smearing all the wayacross the entire chart. Valuable targets should notproduce such obviously wide patterns. In very badground conditions, a good target may have a fewsmall bar segments in the negative area due tomineralization. However, the pattern will showmostly positive bars, in a fairly narrow tall group.

Chapter 3 XLT® Quick Start

Pinpointing the TargetOnce the decision has been made to dig, move theloop off to one side of the target area, squeeze andhold the TRIGGER on the handle, and "X" the loopover the spot where you believe the target to be.Note that the TRIGGER also has a locked forwardposition that accomplishes the same thing assqueezing and holding it.

While the TRIGGER is being held, the loop doesn'tneed to be moving to detect the target. The loopmay be moved slowly over the area. The displaywill indicate depth in inches and will also show thestrongest reading to aid in pinpointing exactlywhere to dig. The shallowest reading on the depthdisplay, the loudest sound coming from the speaker,and the two bars lining up with each other, indicatethe center of the target. Don't forget to "X" thetarget as pinpointing cannot be accurate unless thetarget is swept from at least two different directions.Once pinpointing is complete, release the TRIG-GER, or return it to the center position.

Pinpointing takes practice. The standard loopprovided with the Spectrum® is a high-powered, 9.5inch design. This loop's strongest traits are in thedetection depth and ground coverage areas. Ifpinpointing becomes difficult or critical, an optionalsmaller loop is suggested. The smaller loops haveadvantages in high trash areas and pinpointing, butwill not detect as deep as the standard 9.5 inch size.

Advanced Pinpointing Techniques

1. Targets that are near the surface, becausethey give a wider response, are harder topinpoint than deep targets. If the trigger is heldand the loop swept over the area, you may notea shallow depth indication. Lifting the loopslightly above the ground, releasing and re-squeezing the TRIGGER and again "X" ing thetarget will aid pinpointing.

2. In the Basic Adjustments, DC Sensitivity(non-motion) directly controls the pinpointingmode. Lower DC Sensitivity settings pinpointshallow targets better.

3. In the PRO OPTIONS under AUDIO, V.C.O.(Voltage Controlled Oscillator) significantly aidspinpointing.

4. The depth reading has two indication bars.The top bar shows the current distance fromthe target, and the bottom bar shows a memoryof the strongest reading. These two bars will beeven with each other when the loop is directlyover the center of the target.

Chapter 3 XLT® Quick Start

Ready to DigPermission - Prior to searching and digging youmust have permission to search private property,from the owner or caretaker.

Laws - Know the laws that apply to the area youare going to search. Laws vary a great deal with theCity, County, State, and Country, regarding the useof metal detectors. Be respectful of private prop-erty, public property, and the laws which governthe use of metal detectors.

Tools - Care must be taken to dig in a way that isfriendly to the landscape. Tools and methods vary agreat deal with the area, season, and types of targetyou are recovering. Check with your dealer forrecommended tools and methods for your area.

Trash - When searching, remove all trash youcome across. This not only makes your futuresearches of the area more productive; it promotesthe hobby of metal detecting.

Get Involved - Your dealer knows of metal detect-ing clubs and organizations which promote andprotect the hobby. A club is a great way to not onlylearn good detecting habits, but to gain permissionto search areas as a group as well as have organizedcompetition hunts.

Factory Preset ProgramsReached from the MAIN MENU, the factoryPRESET PROGRAMS give a quick start for:

Coins: general purpose settings, discriminates(rejects) most common junk items like nails, foil,pull tabs, and hot rocks; and responds to most coinsand large jewelry. Use in lawns, parks, and play-grounds where lots of trash rejection is desired.

Coin & Jewelry: less discrimination (less trashrejection), desirable because of the high degree ofvariance found in jewelry alloys. More diggingrequired. Good program for lawns, parks, andplaygrounds. Use screen more than sound.

Jewelry & Beach: similar to Coin & Jewelry, butPro Options are changed for salt water.

Relic: even less discrimination than Coin & Jewelryor Jewelry & Beach, all types of metals exceptsmall iron items like nails, and some stainless steel.Brass, lead, aluminum, as well as copper, silver,and gold all respond solidly. Ferrous (iron), such aslarge nails, weapons, and cannon ball fragmentswill also respond . Suitable for all significant targetsand separate ferrous/non-ferrous by display indica-tions.

Prospecting: NO AUDIO DISCRIMINATION. Allmetals respond with beep. But V.D.I. numbersshow only for metals that could be gold. Dig onlyV.D.I. number (possibility gold) targets and avoidiron. Targets which cause an audio response, with-out causing a V.D.I. number to appear on thedisplay, are not likely to be gold nuggets. Althoughhigh-frequency gold-shooting detectors will re-spond better, this mode will offer good results forthe occasional nugget hunter by responding tonuggets in the nine-grain and heavier category.

Chapter 4 XLT® Basic Adjustments

More BasicsAll the MENU items are tied together so that theARROW up and down controls scroll through everyadjustment screen. If you continue to press theARROW down you can go beyond the last BASICADJUSTMENT (View Angle) and into the PROOPTIONS. If the ARROW up control is pressedafter VOLUME, you will be scrolling backwardsthrough the options starting with the end of thePreset Programs, then the MAIN MENU, then theend of the PRO OPTIONS.

An important feature of the ARROW controls; If aBASIC ADJUSTMENT has been made (for ex-ample Volume) and the trigger has been squeezedand released to return to a search mode, you canreturn to the volume adjustment simply by pressingeither of the ARROW controls. This shortcutreturns to the last adjustment that was made therebyallowing an operator to switch directly from asearch mode to the adjustment currently being finetuned. This feature is desirable as you start usingBASIC ADJUSTMENTS or PRO OPTIONS thatare located further down the menu listings, or anyadjustment that may require some trial and error tofind the appropriate setting.

If care is taken to use a desired adjustment screenlast (just prior to squeezing and releasing the TRIG-GER for a search mode), Custom Programs (such asa competition hunt program) can use this ARROWRETURN feature to allow quick easy access to themost used feature (Transmit Frequency). Use thatfeature (adjustment screen) last, just prior tosqueezing and releasing the TRIGGER for search-ing. Then during searching, press either ARROW toreturn directly to that adjustment screen.

"Hot Key" Shortcuts"HOT KEYS" will save time as they allow easyaccess, from the search mode, to the most neededadjustments. They are painted on the bottom of thecontrol box for field reference.

COIN PROGRAM - Squeeze & release TRIGGERafter automatic battery check.

SCROLL OPTION - After battery check, useARROWS to scroll all the current settings / menus.

5. Silent SearchThe ability of the detector to be operated withoutthe threshold or background hum that is normallyheard continuously during operation. Theinstrument is silent until a target is detected.

Select SILENT SEARCH with the ARROWcontrols and use the ENTER control to turnSILENT SEARCH ON or OFF.

AUDIO DISC. needs to be ON and MIXEDMODE needs to be OFF for SILENT SEARCH toperform properly.

In Pro Options the Discriminate feature can beused to accept all metal targets while usingSILENT SEARCH. It is not possible to achieve anon-motion searching mode with SILENTSEARCH ON. When SILENT SEARCH is ONthe all metal pinpointing mode continues toproduce a threshold. This may not be noticed, asonce the pinpoint mode detunes for better targetcenter locating the threshold is not present.However, releasing, re-squeezing, and holding theTRIGGER with the loop at waist level a thresholdwill be noted. Press ENTER.

SILENT SEARCH ON OFF

TO CHANGE PRESS ENTER

Tip - A threshold hum isrecommended as it oftenfades over rejectedtargets providinginformation about targetsand ground conditions. Ifthe constant noisebothers or distracts youand reduced AUDIOTHRESHOLD doesn'thelp, select SILENTSEARCH.

6. Mixed ModeA unique hybrid operating mode. It is an all-metal(DC non-motion, non-discriminate) mode,working simultaneously with a discriminate (ACmotion discrimination) mode. It is two modes, onedetecting everything and another discriminating,operating at the same time.

Select MIXED MODE with the ARROW controls,press ENTER control to turn MIXED MODE ONor OFF.

AUDIO DISC needs to be ON and SILENTSearch needs to be OFF, for MIXED MODE toperform properly.

When Mixed Mode is on, all types of metals willproduce a sound (beep).

Discrimination Channel - When the loop is inmotion, targets accepted by the discriminateprogram will produce a high-pitched beep. Targetsrejected by the discriminate program will producea lower pitched beep. High-pitched or low-pitchedbeeps are directly determined by the discrimi-nation settings. An operator can select discrimi-nate settings through the selection of an entireProgram or by adjusting the accept and rejectV.D.I. numbers in the Pro Options underDiscrimination (EDIT).

All Metal Channel -When the loop is not inmotion, or moved slowly, all types of targets willproduce the same low-pitch beep. All-metalchannel will by nature detect deeper than thediscrimination channel. Deeper targets willproduce a lower volume sound when the loop ismoved slowly over the area.

MIXED MODE ON OFF

TO CHANGE PRESS ENTER

Tip - Advanced operators cangain extra depth by monitoringthe all-metal and discriminatechannels simultaneously,checking depth and diggingtargets too deep for thediscriminate channel alone.For even more informationabout the target, Pro OptionsTONE I.D. and or V.C.O. canbe added to produce a trulyunique advanced users mode.

Tip - Preset levels workwell for most conditions.Reduced levels willimprove stability in difficultconditions. Increasedlevels will improvedetection depth if stabilitycan be maintained.

Tip-Remember that oncethe TRIGGER issqueezed and released togo to a search mode, youcan return to the lastadjustment screen usedby pressing eitherARROW control.

8. D.C. SensitivityUsed to select the sensitivity (degree that the detectoris responsive to signals) while the detector is beingused in non-discriminate modes. These are modes thatdo not require movement of the loop to respond. D.C.SENSITIVITY fine tunes stability and pinpointing.

Select D.C. SENSITIVITY with the ARROWcontrols, and press ENTER. Use ARROW controls toselect the desired D.C. SENSITIVITY level shown bythe number on the right. Press ENTER. D.C.SENSITIVITY levels should be selected carefully toallow smooth, stable and predictable operation whileallowing for reasonable pinpointing.

A.C. and D.C. Sensitivity Adjustments aretraditionally the way to alter detection depth andstability. There are other methods available in thePRO OPTIONS under SIGNAL (TRANSMIT,RECEIVE), PREAMP GAIN.

30D.C. SENSITIVITY

MIN MAX

Tip - Typically, lowerD.C. SENSITIVITYsettings pinpoint shallowtargets far better thanhigh settings. Highsettings will however,produce more pinpointing(as well as non-discriminate modedepth). Pinpointing(TRIGGER squeezed),MIXED-MODE, andV.C.O. AUDIO aredramatically impacted bythe D.C. SENSITIVITYsetting.

9. BacklightUsed in dark conditions to light the display,improving visibility.

Select BACKLIGHT with the ARROW controlsand press ENTER. Use the ARROW controls toselect the desired BACKLIGHT level. TheBACKLIGHT level will be visible on the display.The current level is shown on the right side of thedisplay. The graphic control knob shows therelationship of the current setting to minimum andmaximum levels. Minimum is 0 (no light). Themaximum backlight setting will reduce battery lifeby as much as 50% depending on the type ofbatteries and how long it is used. LowerBACKLIGHT settings will have significantly lessdrain on battery life.

When the detector is first turned on, it is normalfor the backlight to be on during the openingdisplay and BATTERY CHECK. If theBACKLIGHT is off, it will fade when the MAINMENU display appears. If the BACKLIGHT isON, it will continue until turned off manually or adifferent program is selected. BACKLIGHT canbe saved as part of a custom program, for examplea NIGHT HUNT program.

When Backlight is ON and the TRIGGER issqueezed and released to begin searching,"BACKLIGHT ON" will appear continually onthe display to warn you of the extra battery duty.

EMERGENCY BACKLIGHT - If in the darkyou cannot see the display to turn theBACKLIGHT on, holding the TRIGGER andpressing MENU will bring up the BACKLIGHTadjustment screen. Release the TRIGGER andpress ARROW up to select a level you can see thedisplay. Squeeze and release the TRIGGER tocontinue.

0BACKLIGHT

MIN MAX

Tip - Use only whenneeded, and only as brightas needed, for acceptabledisplay visibility. Backlightuse will decrease batterylife. The brighter the level,the higher the batteryusage.

CAUTIONIf the instrument is turned ON and theEMERGENCY BACKLIGHT sequence isused, the BACKLIGHT will stay ON onlywhile you stay in that program. PressingMENU and selecting another program willturn BACKLIGHT OFF, if BACKLIGHTis not also ON in that particular program.If in the dark at the time the instrument isturned ON, you may need to squeeze andrelease the TRIGGER and then use theEMERGENCY BACKLIGHT sequence.You can then find the program you desire,press ENTER, press ENTER for AirBalance, and press ENTER for GroundBalance. Use the EMERGENCYBACKLIGHT ON sequence a second timeif the BACKLIGHT fades in that program.Unlike past Spectrum® instruments, theSpectrum® XLT® BACKLIGHT is nodifferent than any of the otheradjustments. It can be saved in the customprograms or short term volatile memory.However, factory preset programs use theOFF (0) setting as a default (standardsetting).

10. Viewing AngleAdjusts the display for visibility in low or hightemperature conditions.

Select VIEWING ANGLE with the ARROWcontrols and press ENTER, use the ARROWcontrols to make changes. The current level isshown on the right side of the display. The graphiccontrol knob indicates the relationship of thecurrent setting to minimum and maximum levels.Squeeze and release the TRIGGER to resumesearching.

VIEWING ANGLE has no impact on battery life.

EMERGENCY VIEWING ANGLE PROCE-DURE- If your detector has been in the cold orheat prior to use, you may not be able to see thedisplay to adjust VIEWING ANGLE. Press theON/OFF control, hold the TRIGGER and pressARROW up. You can then use the ARROWcontrols to find a VIEWING ANGLE level thatallows you to read the display. Squeeze andrelease the TRIGGER to begin searching. Like theBACKLIGHT, you will lose your custom VIEW-ING ANGLE setting if you change Programs.You may need to use the EMERGENCY VIEW-ING ANGLE PROCEDURE to see the display.Select the program you desire, use the ENTERcontrol to enter, Air/Ground Balance, then againuse the EMERGENCY VIEWING ANGLEPROCEDURE if the display is unreadable.VIEWING ANGLE is preset at average levels inthe factory preset programs. The display may beunreadable at either of the extreme settings in aparticular environment. Custom VIEWINGANGLE settings will be saved when CustomPrograms are stored for future use.

25VIEWING ANGLE

MIN MAX

Tip - In cold temperaturesthe display typically willbecome slower at respond-ing. Settings toward MAX(higher numbers) speedsthe display and improvesvisibility at cool tempera-tures. In warm tempera-tures or intense directsunlight, the display maybecome difficult to see.Settings toward MIN (lowernumbers) will improvevisibility of the display in allbut extreme situations. Iflarge variations in condi-tions result throughout theday or night's search, youmay have to make severalVIEWING ANGLE adjust-ments to maintain gooddisplay visibility.

Basics of Pro OptionsThe PRO OPTIONS are used to make the moreintricate adjustments available on this model. ThePRO OPTIONS are divided into five major catego-ries of menus, structured similar to the BasicAdjustments. Methods of entry, adjustment, exit,and re-entry remain the same.

To enter the PRO OPTIONS from a search mode,press MENU and the MAIN MENU will appear.Use the ARROW controls to select PRO OPTIONSand press ENTER. The PRO OPTIONS menu willappear on the display. There are two pages to thePRO OPTIONS menu (PG. 1/2 Page one of two).

The ARROW controls are then used to select thedesired PRO OPTION category.

The five major categories have options specific totheir titles. For example, all the options underAUDIO have to do with the way the audio circuitsof the instrument behave. Once a category has beenselected and the ENTER control pressed, theARROW controls can then be used to scrollthrough all the options even beyond that categoryi.e., beyond PRO OPTIONS, back to PRESETPROGRAMS, and BASIC ADJUSTMENTS. Thecategories will only reappear if MENU is againpressed, or at specific times during scrolling (tooffer short cuts).

From this point forward, we will assume that youknow how to use the MENU control, the ArrowControls to make a selection, the ENTER control toenter or select that option, the Arrow Controls tomake adjustments, and the MENU to exit. Remem-ber, squeezing and releasing the trigger returns to asearch mode. Arrow Controls can be used to returnfrom the search mode to the last menu or adjust-ment display used.

1. Ratchet PinpointingPinpointing feature, automatically de-tunes foreasy target-center locating.

ON - Automatically aids in pinpointing. When theTRIGGER is squeezed and held for pinpointing,RATCHET PINPOINTING will shrink the size ofthe signal as the loop is passed over the target areaseveral times. The signal will not fade completelyunless the loop is moved too far away from thetarget center.

OFF - When OFF, the signal will remain originalsize giving some indication of its size and shape.Manual shrinking is completed by squeezing andreleasing the TRIGGER several times as the loop ispassed over the target. Manual shrinking cancompletely eliminate the target. If the target nolonger responds after manual shrinking, move theloop away from the target, squeeze and release theTRIGGER, and again sweep the loop over the area.If the target is a metal, it should again respond.

2. S.A.T. SpeedSelf-Adjusting Threshold (auto-tune) smooths theTHRESHOLD, OFF (0), or ON (1-10).

Without S.A.T. SPEED (a setting of 0), changes inthe ground (and the passage of time) will tend toproduce changes in the THRESHOLD sound. TheTRIGGER will have to be squeezed and releasedrepeatedly to maintain the THRESHOLD. This isparticularly noticeable in non-discriminate modes,although S.A.T. SPEED will also tend to addstability to discriminate modes. S.A.T. SPEEDs 1through 10 will automatically correct for suchTHRESHOLD changes.

S.A.T. (auto-tune) is a feature that has been usedon metal detectors dating back to the 1970's. Itadds a loop-motion requirement to modes whichare ordinarily non-motion. It is also known toproduce some variations in the responses to hotrocks (rocks more mineralized than the surround-ing ground) which change with different speedselections.

Only enough S.A.T. SPEED required to maintainstability is recommended. Typically normal coinsearching requires slower (lower number) speeds,beach hunting and relic hunting require slightlyfaster speeds (higher numbers), and prospectingrequires the fastest settings (highest numbers).

3. Tone I.D.Assigns each V.D.I. number its own distinct toneor pitch. Target ranges can easily be identified bytheir sound. The higher the V.D.I. number, thehigher the pitch of their sound. Reject targets stillbreak up or "cut-out".

Tone I.D. is used in the discriminate or motionmodes. When ON, each V.D.I. target number hasits own audio frequency or pitch (191 differentpitches). The higher the V.D.I. number, the higherthe pitch. Where a target indicates on the V.D.I.scale can be immediately recognized. The soundthat rejected targets produce will still be canceledor modified (broken up) by the discriminate circuit.

The 191 different pitches or tones activated withTONE I.D. cannot be adjusted as to their pitch.Each V.D.I. number's sound is predetermined bythe factory and is not adjustable, nor will they shiftwith TONE (AUDIO FREQUENCY) adjustments.TRANSMIT FREQUENCY settings will add slightvariations to these tones.

Tips - Great for coin,jewelry, and relic search-ing. Can be used incombination with MIXEDMODE.

4. V.C.O.Voltage Controlled Oscillator produces a higherpitched tone the stronger the target becomes.

Voltage Controlled Oscillator is a feature that willonly work in the non-discriminate modes. When itis ON, the stronger the response the higher thepitch of the sound. An excellent aid in pinpointing,V.C.O. will only function when the trigger issqueezed for pinpointing when activated in a dis-criminate mode.

D.C. SENSITIVITY settings will dramaticallychange the performance of V.C.O. D.C. SENSI-TIVITY settings above a level of 35 may peak theaudio pitch too soon to allow V.C.O. to be useful.D.C. SENSITIVITY settings of 35 or below (lowernumbers) are recommended.

Tips - Turn ON if elon-gated Bigfoot or Goldfootloops (differentiatingdesigns) have beeninstalled.

6. Modulation Allows motion modes to produce different volumelevels based on target depth.

Modulation is used in the discriminate or motionmodes. When ON, it allows the depth of the targetto dictate the volume of the response. Thus deeptargets can be easily recognized by their lower-volume sound. If OFF, the discriminate or motionmodes will produce the same volume of responseon all detected targets regardless of depth. The useof MODULATION allows for the singling out ofdeep targets in the standard discriminate mode. Itsaves time by eliminating the checking of eachtarget with the depth indication in the pinpointmode.

Tips - If you have excellenthearing and want to singleout deep targets by theirlower-volume responses,use modulation. ON is thedefault (standard setting)for all factory PresetPrograms. If your hearingisn't the best, the OFFsetting is recommended.

7. AutoTracAUTO TRAC™ allows the instrument to automati-cally readjust the Ground Balance setting duringsearching. This readjustment allows for naturaloccurring changes in the ground mineral of an area.By maintaining an accurate Ground Balance,detection depth and stability are enhanced. AUTOTRAC™ is recommended for typical search condi-tions. If, however, a great deal of decomposedman-made iron is encountered, AUTO TRAC™OFF, or a reduced AUTO TRAC™ SPEED isadvised. AUTO TRAC™ operation is affected byTRAC INHIBIT.

9. Trac SpeedDictates when AUTO TRAC™ adjusts GroundBalance.

Trac Speed allows adjustment of the amount ofground mineral change required to causeAutotracking to occur. At slower speeds (lowernumbers) it takes a significant change in theground to cause tracking to occur. At faster speeds(higher numbers) it takes very little change in theground mineral to cause tracking to occur. The endresult, more tracking occurs at higher numbers thanat lower numbers. Too much tracking can causeerrors in the ground balance setting. Not enoughtracking can result in the ground balance settingnever catching up with changing ground. TRACVIEW is used to see how much tracking is occur-ring. Generally, a faster (higher number) TRACSPEED is needed for more consistent groundconditions. Slower TRAC SPEEDS (lower num-bers) is needed for more inconsistent groundconditions. "TRACK" appearing every three to fivesweeps of the loop is the ideal setting when theground conditions will allow.

10. Trac OffsetAllows AUTO TRAC™ to track ground mineralseither positive or negative in relationship to thecorrect setting (under, or over kill).

TRAC OFFSET allows the AUTO TRAC™feature to track the ground slightly more or lessthan what would normally be considered perfect,mostly for experts that prefer a slight offset.

A slightly positive offset can be used to enhancethe responses of small metals (gold nuggets) inhighly-mineralized ground. Positive is indicated bya slight increase in threshold as the loop ap-proaches the ground in the all-metal mode. Dis-crimination and depth may also be improved.

A negative offset may be used to eliminate particu-larly troublesome "hot rocks" in areas that areotherwise difficult to search. Negative offset isindicated by a loss or slight decrease in the thresh-old as the loop approaches the ground in the all-metal mode.

11. Trac InhibitPrevents AUTO TRAC™ from tracking theground during target detection.

TRAC INHIBIT ON prevents the AUTO TRAC™feature from altering Ground Balance during thedetection of targets. This prevents the possibilityof tracking to the corrosion associated with mostmetals. TRAC INHIBIT ON is recommended formost searching conditions. Some metals do notcorrode (GOLD) and since tracking is extremelyimportant in high mineral conditions, the ability toturn TRAC INHIBIT OFF is available. OFF isautomatically selected in the Prospecting Programand is recommended for prospecting.

12. Coarse G.E.B.(Manual Ground Balance) Allows viewing thecurrent automatic Ground Balance setting (Air/Ground Balance) and/or manual overriding of theautomatic Ground Balance.

COARSE & FINE G.E.B. (Ground ExclusionBalance, or ground rejection) allows manualoverride of the automatic balancing features toselect a specific Ground Balance setting.COARSE allows major adjustments. FINE allowsminor adjustments near the COARSE setting.

Before attempting manual Ground Balance adjust-ments, turn off AUTO TRAC™ since it will alter anymanual changes you make. Manual Ground Balancewill begin at the setting selected by the automatic(Air/Ground Balance) sequence. An Automatic Air/Ground Balance performed after manual adjustmentwill cancel the manual setting. To maintain a manualsetting, the Automatic Air/ Ground sequence must beavoided by squeezing and releasing the TRIGGERwhen, and if, the Air Balance instruction appears. AirBalance instructions may appear during Basic Adjust-ment or Pro Options selections following the manualadjustment.

When manually adjusting the Ground Balance, it isnecessary to make an adjustment in COARSE and/or FINE, then squeeze and release the TRIGGER.The TRIGGER can be held in, and the loop low-ered and lifted over the ground to check for achange in sound which would indicate imperfectGround Balance. To return to the Ground Balancedisplay for further adjustment, press either of theARROW controls. When perfectly Ground Bal-anced in a search mode, the TRIGGER can besqueezed and held, and the loop lowered and liftedwith very little change in the threshold hum.

13. Fine G.E.B.FINE G.E.B. is used to make smaller adjustmentsto the Ground Balance range on either side of theCOARSE setting. The FINE setting combines withthe COARSE setting to determine the actualground rejection level. To determine exactly whatlevel the automatic Air/Ground sequence selected,it is necessary to check both COARSE and FINElevels.

Manual Ground Balance will rarely be used forperfect balancing as the automatic balance isextremely reliable. It is generally used to offsetGround Balance for the same reasons AUTOTRAC™ OFFSET is used.

In COARSE or FINE, lower numbers indicate aGround Balance setting toward the negative side ofthe V.D.I. scale (iron). Larger numbers indicate aGround Balance setting toward the positive side ofthe V.D.I. chart (salt). Bad ground conditions(high mineralization) may be described as eithermagnetic (negative or low numbers) or conductive(positive or high numbers). COARSE and FINEsettings of 0 represent a ground rejection similar toa V.D.I. number of -95. COARSE and FINEsettings of 255 represent a ground rejection levelsimilar to a V.D.I. number of +10. This V.D.I.range from -95 to +10 represents the ground rejec-tion range of this instrument. If ground balance(either automatic or manual) occurs near the 255COARSE setting, significant loss in sensitivity canbe expected to targets which indicate in the V.D.I.number range of 1 to 10. However, manual groundbalance doesn't exactly work like a discriminator,where V.D.I. numbers are simply REJECTED.The actual phase of Ground Balance is out ofsequence with most targets; thus some responseswill occur even if COARSE & FINE G.E.B. arematched exactly to a particular targets V.D.I.number.

targets it cannot readily identify. Therefore, ifpositive +95 is ACCEPTed, questionable targetsmay be dug that indicate this number and canproduce some interesting recoveries. A good tipregarding positive +95: If a target indicates 95,and the depth display indicates it as being fairlydeep; dig it. If the depth display indicates it asbeing fairly shallow, it is more likely to be trash ora hot rock.

The first 30 to 40 negative numbers below zero alsoimpact detection depth. Most iron indicates furtherinto the negative numbers. Thus the first 30 to 40negative numbers can often be ACCEPTed withoutdigging much iron. ACCEPTing from the positivenumbers down as low as minus 30 to 40 has thelargest impact on the lower end of the positivenumbers. Sensitivity to small jewelry is increasedhowever, sensitivity to foil is also increased. On abeach or in a park that has lots of small foil,ACCEPTing down to minus 30 to 40 may not bepractical. While ACCEPTing these minus numbers,a reduced sensitivity setting may help eliminatesome of these small bits of unwanted foil.

ACCEPTINGing all V.D.I. numbers will producethe best overall detection depth however, with theamount of trash in most areas, searching with norejection is seldom practical. TONE I.D. and orMIXED MODE are more practical choices. Theidea of discrimination is to ACCEPT V.D.I. num-bers most likely to be valuables and to REJECT theV.D.I. numbers most likely to be trash. Diggingease, and acceptability in an area will also decidethe amount of ACCEPTed V.D.I. numbers desired.No metal detector can reject all trash while accept-ing all valuables. The deeper you want to detect, themore trash you will need to accept and dig.

The detector sees metals electronically; thus somevaluable and non-valuable targets may look identi-cal to the detector. To select ACCEPT and RE-JECT V.D.I. numbers is to gamble that the areasyou select for ACCEPT will be good targets, andthe area you select for REJECT will be trashtargets. A factory program which uses the law ofaverages usually produces more good targets thantrash. The EDIT feature allows you to fine-tune theACCEPT and REJECT settings for your area andtypes of desired targets, further improving theseodds.

If you do not return to the LEARNselection screen and turn LEARN OFF,the detector will continue to learn (AC-CEPT or REJECT) every metal target itencounters. Selecting LEARN OFF afteryou have learned a target is extremelyimportant.

Iron alloys, such as steel bottle caps ornails, should never be used for thisLEARN method of programming. Be-cause of their inconsistent V.D.I. indica-tions, iron alloys tend to scatter or other-wise confuse the discriminate program.If this occurs, it is best to turn the detec-tor OFF, back ON, and re-ENTER thedesired Program to return to the originalfactory pre-set discriminate settings.

18. Recovery SpeedSpeeds target responses, so several targets that areclose together can each respond.

When a metal is detected, it takes a fraction of asecond for the detector to process the signal beforeit can respond to another metal target nearby. Thetime it takes to process the first metal target signalso that the second metal target signal can respondis called RECOVERY SPEED.

There are advantages and disadvantages to fast(high numbers) and slow (low numbers) RECOV-ERY SPEEDS. Faster RECOVERY SPEEDs workwell in high trash areas. However, they will havesome difficulties with very deep targets as well asdouble responses on shallow targets. SlowerRECOVERY SPEEDs do not work very well inhigh trash areas. However, they will have betterresponses on very deep targets. Slower speeds alsohave more definitive discrimination sounds. Acustom setting needs to be found that suits thepreferences of the individual and the conditions inthe area. As a general rule, the closer together themetal targets are in an area, the faster the recoveryspeed should be. The more spacing between tar-gets, the slower the speed should be. Don't use thefast speed if you don't need to.

In very trashy areas it is recommended to switch toa loop smaller in size than the standard 9.5 inchblack loop. Smaller loops offer better separationbetween targets. However, larger loops detectdeeper and cover more area with each pass. RE-COVERY SPEED combined with a smaller loopcan be used to search severely trashy areas.

19. Bottlecap RejectAdjusts how strongly the instrument rejects orbreaks up on iron.

Most starting programs use the minimum setting.As larger numbers are selected, more bias rejectionagainst iron occurs.

The advantage of higher BOTTLECAP REJECTsettings is that in high-trash areas more decisiveiron rejection occurs. Trash becomes easier toidentify by the broken sounds they produce.

The disadvantage of a high Bottlecap Rejectionsetting is if an iron target is close to a good metal,the high degree of bias against iron may cause thedetector to cancel both responses. Another disad-vantage is that all targets, iron and non-iron, tend tostart sounding more broken at high levels ofBOTTLECAP REJECT. The operator needs tofine tune BOTTLECAP REJECT according to theirpreferences and the conditions being searched.

Some ground conditions make it difficult for theinstrument to recognize iron. BOTTLECAP RE-JECT allows compensation for these areas.

VISUAL DISC. "ON" eliminates both the V.D.I.number and the ICON (NAIL, FOIL, PULL TAB,etc.) of REJECTed V.D.I. numbers from appear-ing on the display. In other words if Visual Dis-crimination is ON, and a specific target is rejected(for example 0-IRON) then 0-IRON will notappear on the display. If VISUAL DISC. is OFF,all the display indications will appear regardless ofwhether the specific V.D.I. number is ACCEPTedor REJECTed.

22. V.D.I. SensitivityControls how strong a target must respond toproduce a display indication, and controls a thirddigit (fraction) of the V.D.I. number.

V.D.I. Sensitivity controls the intensity (strength)of the target signal needed to activate the displayindications. A low V.D.I. Sensitivity setting wouldrequire a strong target signal to trigger the displayindications. A higher V.D.I. Sensitivity settingwould require very little target signal to trigger thedisplay indications.

To provide greater specific target resolution, levelsof 86 and above will provide a third V.D.I. digit(.0) to better evaluate targets. During EDIT onlythe first two digits can be programmed ACCEPT orREJECT.

As with all sensitivity levels, if set too high for thearea, the detector will become unstable and thedisplay indications unreliable.

Low ground mineralization is typically a goodindication that high V.D.I. sensitivity settings areappropriate. Heavy mineralization or electricalinterference are conditions where a lower V.D.I.Sensitivity setting is appropriate.

This feature is designed to allow adjustment of thedisplay stability. However, because theinstrument's display and audio tone are closelyassociated in many of the audio modes, the V.D.I.Sensitivity may increase or decrease overall audiosensitivity.

23. D.C. PhaseMeasurement of the ground mineralization, ormeasuring the phase (V.D.I. reference number) of aspecific metal target during pinpointing.

When D.C. PHASE is ON, and the TRIGGERsqueezed and released, normal searching begins.When a target is located, or when the operatorwants to measure a target or the ground, the TRIG-GER is squeezed and held as if to pinpoint. Whenthe loop is held stationary over the target or ground,the D.C. PHASE is shown on the upper-right sideof the display. The depth reading can be used tohelp center the loop over a target for more accurateindications. The audio tone will also assist incentering the loop over the target.

Metal targets in the ground will produce a measure-ment which represents the target indication ± theground measurement. To measure the target alone,move the loop off to one side (being sure to holdthe loop directly on top of the ground mineral), andrelease and re-squeeze the trigger. Then move theloop back over the target. This should allow aproper D.C. PHASE reading for the target alone.

The relationship between D.C. PHASE, GroundBalance, V.D.I. number and Discrimination iscomplex. Results are not always repeatable invaried ground conditions. Ground and target re-sponses can distort the detection field of the loop ina number of ways, by bending, reflecting, absorbingand thus altering the phase and amplitude thedetector measures. This in turn produces inconsis-tencies in the relationships of these features.

The D.C. Phase of the ground has a relationshipto the proper Ground Balance setting. This is ofparticular interest to those who use the optionalCOARSE or FINE G.E.B. (Manual GroundBalance). Manual Ground Balance has a rangethat covers V.D.I. numbers from -95 - +10. AManual Ground Balance Coarse setting of 0equals a D.C. PHASE of negative -95. A Coarsesetting of 255 equals a D.C. Phase of +10. Asmentioned under COARSE and FINE G.E.B.,Ground Balance is not the same as EDITingthese V.D.I. numbers for REJECT. However, ifyour ground measures -90, ACCEPTing V.D.I. -90 will produce operational problems as thedetector will see the ground as a target. With thesame logic, if a target measures -90, and theground measures -90, and the detector is GroundBalanced to this -90 ground, such a target will bevirtually invisible to the detector. These conditionswould be extremely rare however; the point isthere must be a difference between the target andthe ground for the target to be detected.

GRAPH ACCUMULATEON OFF

TO CHANGE PRESS ENTER

(Display section)

24. AccumulateON combines SignaGraph™ information overmultiple loop passes, OFF shows SignaGraph™information only from the last sweep of the loop.

Accumulate allows the SignaGraph™ to continuallycollect information. This collecting of informationcontinues from one sweep of the loop to the next.Eventually, if only ACCUMULATE is selected,the SignaGraph™ will completely fill, requiringthat the TRIGGER by squeezing and releasing toclear it so that further information may be viewed.FADE is suggested to be used in combination withACCUMULATE so that non-current informationgradually disappears and excessive TRIGGERing isnot required. FADE will gradually reset or clear theSignaGraph™ to eliminate old information.

Tips - ON is suggested,since it takes severalsweeps of information torecognize trends.

GRAPH AVERAGINGON OFF

TO CHANGE PRESS ENTER

25. AverageEmphasizes the most common or predominateSignaGraph™ indications.

AVERAGE does not necessarily allow showing ofall the available information on the SignaGraph™.It averages the information received, and shows thisaverage on the SignaGraph™. When used in combi-nation with ACCUMULATE it has more informa-tion to average, which results in more accurateindications of trends. FADE is suggested to clearthe display of old information, rather than excessiveTRIGGERing.

Tips - Most beneficialwhen used in combinationwith ACCUMULATE.AVERAGE ON is sug-gested as it reducesindications uncharacteris-tic of a particular target,which may occur due toloop angle or targetpositioning in the ground.

(Display section)

If ACCUMULATE is OFF, and AVERAGEis OFF, then SINGLE SWEEP is active.

SINGLE SWEEP displays SignaGraph™information received during the current sweepof the loop, no more and no less. The nextsweep of the loop will clear all informationfrom the SignaGraph™ and list the informa-tion received only within that sweep. Fade isnot needed in the SINGLE SWEEP mode aseach pass of the loop will clear the displayand provide current information automati-cally. Several SignaGraph™ indicationsamples occur during each sweep of the loop.It is therefore normal to see one or moreSignaGraph™ bars, even in the SINGLESWEEP mode.

7FADE RATE

MIN MAX

(Display section)

26. FadeClears or fades non-current SignaGraph™ informa-tion (bars).

FADE allows past information to automaticallyclear or fade from the SignaGraph™. Without Fade,or with too slow of a FADE rate, the SignaGraph™will fill with information that is no longer valid asyou sweep through a search area.

A minimum setting of 0 equals no fade at all. TheSignaGraph™ information will continue to appearuntil the trigger is squeezed and released. A maxi-mum setting of 14 selects a very quick fade rate.The SignaGraph™ information will automaticallyclear from the graph quickly. Ideally, a Fade Rateshould be selected that allows time to adequatelyview the SignaGraph™ information yet still clearthe graph in a timely manner.

Tips - Recommendedfor all but the SINGLESWEEP mode. Adjustthe rate of FADing sothat you have time toview the SignGraph™prior to it resetting.However, do not set itso slow as to show non-current information.

TRANSMIT BOOSTON OFF

TO CHANGE PRESS ENTER

(Signal, Transmit, Receive))

27. Transmit BoostSelects the intensity of the signal transmitted fromthe loop.

There is a transmit and a receive coil within theloop housing. If too much signal is transmitted forthe ground conditions (magnetic and/or conductiveground), the signal will saturate the receiver andthus eliminate good ground penetration (depth). Byturning OFF the TRANSMIT BOOST, groundpenetration in most cases will return. The receivesignal can then be optimized using PREAMPGAIN, to provide the best depth possible in suchextreme ground conditions.

When "OVERLOAD" regularly appears on thedisplay, there are either very large strong metaltargets present or the ground mineralization is suchthat the detector cannot properly operate. Sweepingthe loop higher above the specific OVERLOADresponse will identify a target. When OVERLOADappears on the display consistently due to groundminerals, selection of TRANSMIT BOOST OFFwill improve depth and stability. During OVER-LOAD the detector is not capable of responding tometal targets. The OFF setting in most cases willresolve such difficulties and provide detectioncapabilities in extreme conditions.

Every time the TRANSMIT BOOST is altered, thedetector needs to be Air/Ground Balanced. Once ina search mode, simply press ENTER to Air/GroundBalance.

Tips - Use ON unless"OVERLOAD" is oftennoted on the display, inwhich case the OFFsetting should beselected. Make sure theOVERLOAD indicationis not caused by a largemetal target, that it iscaused by the groundminerals.

4TRANSMIT FREQUENCY

MIN MAX

(Signal, Transmit, Receive))

28. Transmit FrequencyAlters the normal operating frequency (6592.5 Hz)to avoid interference from other metal detectorsoperating close by. Operating frequency is thefrequency the detector transmits and receives itssignal.

Lower numbers equallower frequencies, 1 = 6027.5 Hz

2 = 6204.7 Hz

3 = 6392.7 Hz

4 = 6592.5 HzHigher numbers equalhigher operating 5 = 6805.2 Hzfrequencies,

6 = 7032.0 Hz

7 = 7274.5 Hz

Other metal detectors operating at the same fre-quency will cause interference. By shifting to adifferent frequency such interference can beavoided from detectors operating nearby.

The best performance will be achieved at thestandard number "4" setting. If however, youcannot search due to interference from other detec-tors, use an alternate frequency.

Remember that once the trigger is squeezed andreleased to return to a search mode, the last optionused can be accessed by pressing either of the arrowcontrols. This ARROW RETURN feature can beused to handily change TRANSMIT FREQUEN-CIES during a competition hunt.

Tips - Use level number"4" (6592.5 Hz) unlessinterference results fromother detectors. Moveaway from level "4" onlyfar enough to preventsuch interference.

2PREAMP GAIN

MIN MAX

(Signal, Transmit, Receive))

29. Preamp GainSelects the intensity of the signal received from theloop.

PREAMP GAIN (called Signal Balance on somemodels) is used to promote stability and perfor-mance. Like a sensitivity control, too muchPREAMP GAIN will result in unstable operationand unreliable indications. Unlike a sensitivitycontrol, PREAMP GAIN will have a substantialeffect on OVERLOAD.

For maximum detection depth, fine tune thePREAMP GAIN to the highest number settingwithout causing OVERLOAD, and/or unstableoperation. More adjustment levels (range) areavailable than what may be usable. You may neverencounter an area where maximum PREAMPGAIN can be used. Electrical interference maymake it difficult to receive an Air Balance at highPREAMP GAIN settings.

Selections such as MIXED MODE or AUDIODISC OFF may not allow as high a PREAMPGAIN level as other selections. This is normal assome of these modes naturally see more targets andground, and they may still provide superior perfor-mance and depth even with the lower PREAMPGAIN selection.

If TRANSMIT BOOST OFF has been selected, it isparticularly advisable to fine tune PREAMP GAIN.

Every time the PREAMP GAIN level is changed,the detector needs to be re-ground balanced. Oncein an operating mode, simply press ENTER to re-ground balance.

Tips - Higher levelsincrease detection depth.However, the detectormust be stable to be ableto recognize a target.OVERLOAD should notappear on the displaywhen only ground miner-als are present.
