Dive Time Remaining (DTR)

One of the most important pieces of information on Sherwood dive computers is the Dive Time Remaining (DTR) numerical display.

The Wisdom2 constantly monitors: 1. No Decompression (NDL) status2. Oxygen Accumulation3. Breathing Gas Consumption Rate


The Dive Time Remaining display will indicate

a) No Decompression (NDL)


The Dive Time Remaining display will indicate

1. No Decompression (NDL)2. O2 Dive Time Remaining

a) In the instance where oxygen accumulation becomes the limiting factor

Dive Time Remaining (DTR)The Dive Time Remaining display will

indicate 1. No Decompression (NDL)2. O2 Dive Time Remaining

a) In the instance where oxygen accumulation becomes the limiting factor

3. Airtime Remaininga) When air consumption time is less

than NDLb) Calculated using diver’s air

consumption rate and current depthc) Tank Icon will appear flashing as a

warning

No Deco Safety Stop• Upon ascending to 20 feet on

any No Decompression dive in which depth exceeded 30 feet a 3 beep alarm will sound and SAFE STOP screen appear.

• Countdown Timer begins at 3:00 min

• Counts down minutes and seconds

• Safety Stop is not Mandatory and no penalty occurs if you surface during countdown

No Deco Deep Stop

• Upon descending below 80 feet on any No Decompression dive a 3 beep alarm will sound and Deep Stop screen appears

• Countdown Timer begins at 2:00 min

• Counts down minutes and seconds

• Deep Stop is not mandatory and no penalty occurs if you surface during countdown
