The speed that it works on is fine for me...I have a back up minn kota but t is hand controlled...so I won't be without a trolling motor. But the fishfinder itself is worth 150 and the battery charger is worth 30...I looked at new trolling motors and they were way too expensive for me. I'm going to keep the setup...for 30 bucks it is worth it. I won't run it on super low speeds anyways.
