GPS stands for Global Position System. A GPS unit is an electronic navigational device
 that indicates the users longitude and latitude. It can be used to get from one point to another point, to
 measure distance traveled, speed, and other related parameters. It works by broadcasting a signal to
 satellites, and interpreting the response data to triangulate a location. GPS units range from $100 to $1000,
 and are used for a variety of purposes both recreational and official. Fun activities with a GPS unit: -
 Geocaching: Geocaching is like a treasure hunt, with a very accurate map. Individuals and organizations set
 up caches of rewards all over the world, ranging from toy army soldiers to bragging rights. The cache
 creator then reveals the latitude and longitude of these caches online, and provides additional clues if
 necessary. The general rule of thumb is, “If you take an item, leave an item, and write in the logbook.â€?
 - Benchmark Hunting: Similar to geocaching, but benchmark hunters seek National Geodetic Survey
 markers, used by the NGS to enable land surveying, civil engineering and mapping activities. These markers
 are generally metal disks. Benchmark hunters who locate a benchmark report their find online and often
 share pictures of the moment of discovery. - Trail running: Wrist-bound GPS units not only measure distance
 travel, but are also able to monitor heart rate, speed, pace and calories burned. Many of these devices also
 log lap times, so you can gauge performance over time. - Boating and Fishing: GPS units are great for
 nautical adventurers, as they help with following fish patterns, marking casting points, favorite fishing spots,
 etc.
