As a Geophite (is that the word I'm looking for?), and having only really played with a GPS in conjunction with a topo map, I'm wondering if anyone here uses a topo & UTM to find the general area of a cache in order to get there, then use their GPSr once in the area? Also, do you keep your units in HHMMSS or in UTM mode to find caches? TIA to all! Lori V. Team Villa5
