The GPS came way before Geocaching. As an avid offroader I have owned a GPS, (Eagle Exlorer) for many years now. But I must say that I have now outgrown that particular unit and had to upgrade as soon as I was caught by the Geo bug, (Magellen Sport track Map). Geocaching has also helped me to use much more of this fantastic tool then I ever would have used before. It has increased my skill and confidence with both GPS and general route finding.
