Yes, I typically only use side imaging on the transom transducer, even when I did have a side imaging transducer on the trolling motor. I will side image scan while running the outboard and will use it when standing on the back deck while pulling crankbaits. Side imaging is good to see what you just ran past.
Since I don’t have a down imaging transducer on my trolling motor at the moment, I really use the 2D sonar, 360, and Livescope on the bow, although DI is like 2D, where you get an idea of what you just ran over with the trolling motor.
If I'm not at work or taking kids to their activities, you might find me on "The Rez" fishing. If not there, I could be in the garage working on my boat.
