A simple description of a TRAX map would be a BLM map for a GPS, but it is so much more than this. Never before has one map been able to cover the needs of sportsmen and sportswomen for hunting, fishing, hiking, biking, camping, and traveling until now. A TRAX map is like taking a BLM map, Forest Service map, County Road Map, Topo map, and a state Game and Fish map and combining them together live on your GPS.
