Selective Availability (SA) turned off at midnight May 1, 2000, improving the precision of civilian GPS from about 1000 feet to about 65 feet. This allowed users to receive a non-degraded signal globally, thus helping to establish geocaching as a hobby. Many events are sharing this anniversary as well as this geocoin to commemorate it. This coin is trackable and has a unique icon.
Collect, share or use as a FTF prize for your geocaches
