Bout to buy new fish finder for front of boat. Going with a DI unit, my question is, can you use a trolling motor transducer with a minn-Kota TM. I have a power drive TM with universal sonar, I know that I have a transducer for the DI. Since the TM slides thru the housing, do you use TM transducer or put it on the transom. If you use TM transducer, how do you rig wire and do use built in sonar on TM for 2d sonar or does TM transducer do both. Sorry for no better wording, but the changes in transducers are hard to keep up with. Thanks for any info.
