I just bought me a Lowrance LMS 480M and got it mounted on my boat. I have been looking at Map Software to buy and was wondering if anyone had any options? I am leaning toward Navoinics Entire US that contains 3000 Lakes, because I fish lakes in Illinois a lot and fish Norfork Lake in AR. Illinois and Arkansas are in different regions so getting the Entire US one gives me all the lakes I fish in one chip. Just want some people's options on which brand is the best. Which has the best detail, if any have waypoints of good fishing spots, etc. Thanks!
