I have a 36v Ultrex and love the spot lock, but the feature I use the most is the heading lock or whatever it’s called. I’m sure all the major brands have it. I can point the motor in a specific direction and dial in the speed I want, and it’ll use gps to take me along that heading. I use it to creep slowly along a grass line or a roadbed or any other stretch of cover and I can just fish and not mess with the trolling motor. I’d wager you’ll be very happy with any of the models that offer these features. You’ll never go back to a regular trolling motor after getting one.
