eTrex supports geocaching GPX files for downloading geocaches and details straight to your unit. eTrex stores and displays key information, including location, terrain, difficulty, hints and descriptions, which means no more manually entering coordinates and paper printouts.
Keep Your Fix
With its high-sensitivity, WAAS-enabled GPS receiver and HotFix satellite prediction, eTrex locates your position quickly and precisely and maintains its GPS location even in heavy cover and deep canyons.
The eTrex series is the first-ever consumer-grade receivers that can track both GPS and GLONASS satellites simultaneously. When using GLONASS satellites, a system developed by the Russian Federation, the time it takes for the receiver to 'lock on' to a position is (on average) approximately 20 percent faster than using GPS.
