It's as easy as pushing the transducer to the stop in the down position. It's also as easy as pulling the transducer up to the forward position. No skill. No effort. Anyone can do it in 1 second. Then change the setting in your unit. I guess you would have to lift the trolling motor out of the water or the pole.
I suppose if you had it on the trolling motor shaft you could use an adapter from the crappie boys that mounts on the shaft to move it past the lower unit. I have mine on a pole I can move anywhere in my boat with forward or down. To each his own I guess.
