I commented about getting a GPS to help find the dumping grounds a few weeks ago and the responses for a GPS sold me, but I don't have a clue which one to buy...fellow anglers would be the best critics in my opinion. I know you can push a button to mark a spot, but can you flag a spot with more than just a dot on a screen on any models - some info perhaps? I'd love to hear any feedback good or bad on what you own. We found an awesome drift in front of the 400 Club yesterday and seemed to lose it after a couple great drifts - muskie chasing a bass I was reeling in, a very large, scarred pike (on the ultralite!), a couple bitten off rigs...LOTS of action.
