I just got this unit and want to have a transducer on both the TM and the transom. I already have the XNT 9 SI 180 T for the stern. There are 2 ways to go for the trolling motor. I could use a XNT 9 SI 180 T with the trolling motor mount or I could buy the XTM 9 SI 180 T which is designed to be mounted on the TM.
I was wondering if there was any advantage of one over the other?
Also I would be in the market for a decent used version of either of these transducers.
Thank for any help.
