I am new to geocaching and I mean REALLY new as in yesterday haha. However the past few day I have only found 3/8 because I have found that my GPS just isn't good enough. I am using a nuvi, so you can see why. It will tell me I am there and then change its mind and say I am 20ft+ away. Really frustrating. We have a handheld, but it is nowhere to be found. If I don't find it soon I will consider buying a new one. Anyways, I am still having fun. May possibly be interested in a swap, you know, if I can find some time when not geocaching!
You will get the hang of it. I have found that my gps and everyone's I know, will sometimes jump around especially around tall building, or in wooded areas. It will often say I'm 2ft away and 30 seconds later I'm 30 foot away when I haven't even moved. UGH! That's kind of where your "geo senses" come in. They will get better and better the more you do.
