I have a 24' deck boat that I use mostly for pulling tubes and water skiing on lakes in Georgia. I will occasionally fish from it, but don't see that as a particularly big use of the boat. My wife just got me a Lowrance Fishfinder/GPS as a birthday present. It looks awesome, but it is also very expensive. I'm not sure I will really get that much benefit from having it, and am thinking of returning it. Before I do so, though, I thought I would seek some input from others about how beneficial they are.
