The document discusses geocaching, which is a treasure hunt where people use GPS devices to find containers hidden by other geocachers around the world. It explains that GPS uses 24 satellites to triangulate a user's location within 6 feet. Typical GPS devices for geocaching cost around $100. Geocachers register on geocaching.com to get coordinates of hidden caches, which are containers used to hold logbooks and sometimes trade items. Users can search for nearby caches and download the waypoints to find them using clues. Geocaching has educational applications and can be connected to different school subjects.
