The problem I have had with GPS accuracy on the lake is the loss of "WAAS" (Wide Area Augmentation System) which keeps your GPS accurate within 3 meters. For the life of me I can't understand why in such an open area I keep losing the WAAS signal on my GPS, and for some reason it seems worse this year than last. Does anyone else have this problem on the lake???

Without WAAS, accuracy can be as much as 100 meters off and I have personally seen this inaccuracy on my GPS. I have rarely loss total GPS / satellite signal however.

GPS is a another extra wonderful tool to HELP with navigation but should never be relied upon totally. It is NOT fail proof and it is never 100% accurate.
