I have a Terrova that I removed from a boat I recently sold. I was using a Garmin with it own xducer on it previous but would like to cut down cables. I have a new (to me) stick steer boat lined up, looking for a good unit to go with this rig. Do you only get 2d sonar using the Terrova transducer? Would you recommend using the trolling motor xducer?

Thanks for replies.
