I’ve been thinking of buying a handheld GPS to take up geocaching. However, I’m a bit at odds of which to buy. So far, I’ve taken interest in Garmin eTrex 10 Worldwide Handheld GPS Navigator, Magellan eXplorist GC Waterproof Geocaching GPS, and Magellan eXplorist 110 Handheld GPS. Are any of these particularly better or worse or more worth it? Or, are there any you would suggest for a newb like myself?
