Excellent info. Thanks.

I do see a Helix 5 with SI that is in my price range. So maybe I'll look into that. Is it generally preferable to have this unit on the console? I would assume you would want it there so that you can idle about with the big motor, looking for cover before you move in closer with your trolling motor? Is this how most people do it?
