The sport where YOU are the search engine
•A high-tech treasure hunt•Need a GPS•Seek a cache based on latitude and longitude coordinates •This is not just a teaching tool, it’s a lifetime activity.
What is Geocaching?
Global Positioning System
•Approx: $100-$500 •Garmin and Magellan are the most popular•Can download cache•Info into the receiver if it is properly equipped•iPhones•Groundspeak App $10
GPS
Using three satellites, you should be able to determine your exact position through trilateration.
Some variables include:TreesBuildingsAtmospheric Interference, etc.
*A typical hand held receiver gets within 5-15 feet.
How Does It Work?
•Build an account on www.geocaching.com
Search by city, zip code, state, driving route, etc. (I usually search by zip code--16506)
Record the latitude and longitude coordinates and read the hints!
How do I find a cache?
•Sign the log book •Trade items—Take something, leave something•Look for travel bugs and geocoins•Be sure to put the cache back in the same
place you found it with the appropriate amount of camouflage.
When you find the cache…
•Get as close to the location as you can.•Insert the coordinates into the GPS. •Follow the compass until it gets to 0-10
feet. •Use your “geosense” to find the cache.
Then what?
Travel Bugs
Geocoins
Collectable and Tradable Items
•Take a bag that includes:•GPS•First Aid kit/bug spray•Pen/Pencil•Swag/Tradable items•Compass
