Fellas, thanks for all the input. From what I gather you purchase the transducer and mount it on the shaft of the trolling motor. You can adjust the Ducer and make a screen change to go from forward looking or down looking. The transducer looks to be around 1500.00. Then you pair that with a compatible Garmin screen. The you tube videos I have viewed on the package really look nice. Of course, most of the videos they are running the big 10 inch screens. I guess if you are going this route you may as well go big or go home. Was hoping that a Garmin pro staffer lurking on the site would offer a hands on water demo.
