If you go Lowrance do not go with the hook series. The Elite FS is a great unit otherwise spend the extra money on a HDS. Carbon and live are superb units. I would imagine the new pros are too but at a lot more cost. You can shop around and get a 9 live with all in one transducer for a decent price plus it has c- map preloaded. Myself I am hooked on touch screen units and Hummingbirds helix units are still behind in that not being touch screen. It’s what ever you feel most comfortable using they are all pretty close to doing the same job sonar wise.
