Just wondering how many gps users out there have trouble getting a strong, any signal ,when you need it most? Planing a trip to the north slope and I am wondering if it's worth packing the weight, backpack hunting?? I have had trouble on the east coast ane they don't seem trustworthy to me, I always carry a compass. We have tried diffrent brands and at times, same thing not enough signal!! Anybody out there had any experience , good or bad? Thanks in advance. Bill.
