so bought for first boat (used). It has Lowrance electronics. Specifically the hook series and has a hockey puck gps unit mounted on the back. I have a chance to get a min Kota Ultrex TM. It says it has a built in transducer, and it also has a hockey puck with it. Im assuming the hockey puck is for helping with the spot lock and such. But as far as the built in transducer will it work with my Lowrance? My current motor has a Lowrance transducer strapped to the motor by the prop.
