What is Geocaching?
• 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.
GPS
• Global Positioning System• Approx: $100-$500 • Garmin and Magellanare the most popular• Can download cacheinfo into the receiver if itis properly equipped• iPhones• Groundspeak App $10

How Does It Work?
• Using three satellites (trilateration), you should be able to determine your exact position.
• Some variables include:– Trees– Buildings– Atmospheric Interference, etc.
*A typical hand held receiver gets within 5-15 feet.
How do I find a cache?
• Build an account on – www.geocaching.com
Search by city, zip code, state, driving route, etc.
(I usually search by zip code--15017)
Record the latitude and longitude coordinates and read the hints!
Then what?
• 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.
When you find the 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.
