I have a Lowrance 332c (don't know if they still sell this model or not) that is good for navigation and locating. Sometimes would appreciate a bigger screen, but overall it works fine. Fish Chip almost exclusively all summer. Got my Lowrance at Thorne Brothers during their spring Musky sale, usually early April I think, and was best price I could find; $100 cheaper than anywhere else and they threw in the chip for free or half off.
