Thanks for the feeback Maury. I only tried one cache this weekend due to lack of time, and it was in a fairly heavy tree cover area, though in the past I haven't had much problem. I had a good signal lock (within 13 ft accuracy) it said, but I guess due to the tree cover, it would "skip" sometimes and not keep track of my location.
I'm going to try for a more open cache or 2 this weekend and see how that goes.
Also, though my TOMTOM allowed me to key in the coordinates to get to the general area, I don't think it'd guide me to the precise location. Does anyone use an auto TOMTOM?
Thanks for the help. I'm clearly a newbie in need!
