We started geocaching a few months and love it! As others have said its allowed us to see places we never would otherwise. I have only used my phone and iPad and I use the official app. We love it! Tried to go on our last trip there was a bunch I wanted to find, but no cell service. Time to upgrade to a standalone unit! We have found 52. It's a grat time and DS enjoys hunting for treasure. Not a big fan of micros and multis, my favorite is an ammo can in the woods! We are TheBraggBunch if you want to friend us. We are premium members. If you haven't tried it at least try it once!!
