Hey guys, Looking for some advice on the best Fishfinder/GPS for my Tracker deep V for next season. My primary fishing is in the great lakes, I live 2 miles from Lake Ontario, and enjoy Oneida, Skaneateles Lakes also. I'd like something that I can find fish with, see structures, and be able to save GPS locations of hot spots. So I'm looking I think for something that's color, has the great lakes in maps, can see structures, and find me fish. I know this is a tall order, but any ideas? My boats only an 18 footer, so I'm not going out in the deep waters of Lake Ontario looking for salmon, I'm mostly fishing for Bass, Perch, Walleye, and other pan fish. Thank you!
