I don`t think they make the sideimage trans. in a thru hull. How would this work? I have seen people with side trans. on the trolling motor, but I don`t think it works as well. I turn mine around at the console so I can glance back at it from time to time. When I see something in my front dualbeam I look to get a clearer view on the side image and see what it is. I mostly wanted mine for scouting. Which I do while idling over areas.
