Wasn't sure which forum to post under because post involves trolling motor; transducer, and units. Going to purchase new Minn Kota trolling motor. My units are Helix 10 Chirp SI GPS G2N. So, my question is...I don't need the "universal sonar or the Mega Down Imaging" that is offered with these trolling motors? Wouldn't the one I have be the best? Question...can my transducer be mounted on the new trolling motors? Thanks
