My wife and I just started Geocaching and are really enjoying it. We both have iPhones equiped with the Groundspeak app. We have found a few caches but have been stumped by many more. My wife thinks that, perhaps, the GPS in the iPhone is not as accurate as purchasing a GPS device that's actually made for that single purpose. There have been several times that, while using the compass feature, the coordinates will "jump" around making it frustrating to follow. Before I go out and spend as much or more on something (as opposed to the cost of the iPhone) I was curious if anyone else has experience with the iPhone compaired to a standard GPS device. As I said, our only experience so far has been on the iPhone. I worry about buying a GPS device and having identical results. Thanks for any help or advice.
