A CDE Definition
A high-tech treasure hunt in which trinkets are stored in a waterproof container ("geocache") that can be located in the wilderness or in a public venue, typically not in plain view. The GPS coordinates of the cache are published on the geocaching website, and the object of the hunt is to locate the cache and enter your name in the log book as well as move objects from one cache to the next. In addition, geocachers may want to share their experiences online. Like a traditional treasure hunt, the contents of one geocache may provide the coordinates to the next one. As of mid-2008, there were more than 600,000 geocaches around the world.
Trackable Travel Bugs and Geocoins
A major goal of geocaching is to track an object as it moves across the country or around the world. In order to track the movement, Groundspeak, Inc., the founder of the geocaching website, developed the "Travel Bug," a physical tag with an identifying number. Groundspeak also issues ranges of IDs for minting "geocoins," which are commemorative coins with tracking numbers, and other sites have issued their own geocoins. When geocachers find Travel Bugs and geocoins, they post their IDs online to update the trackable's new geocache location. For more information, visit www.geocaching.com. See portable GPS.
Specialized for Geocaching
A GPS-based unit that is designed for handheld operation or windshield/dashboard mounting in a vehicle. Portable GPS devices offer many of the navigation features of in-dash units and can run for several hours on battery before being plugged into the car's power outlet. However, because they are not connected internally to the vehicle's odometer, they can get off course if there is no line of sight when traveling in tunnels, in between tall buildings or on lower levels of bridges. See in-dash navigation, GPS augmentation system and GPS.
