I just started on 4/7/2012 and downloaded an app to my phone (not the geocaching app for $9.99, a free app) and so far it has been pretty good. First day just trying to get accustomed to it was a learning experience but we figured it out. A lot of our problem was not knowing exactly what we were looking for. We found 2 or 4 our first day. The GPS got us to the general locations and in most cases to the exact spot. The two we did not find I think were because we did not know what we were looking for. In one case, we went back to it and found it our second try (only because my daughter never told me she saw something and didn't know what it was and it ended up being what we were looking for). I'm going back to the other and looking again because I think I now know where it is due to the clue since I had no idea what the acronym meaning was in the clue (now I do). Yesterday we logged 8 finds and 1 DNF. I'm still pondering the DNF. We were in the area the GPS took us and it looked like the right spot but I'm not sure where it was. The only thing we did find was a dead animal in a plastic bag
I'm not a hardcore geocacher but I do think some day I will be getting a handheld GPS mainly because of the battery life but for now my android has been working out very well for me.
