I'm with others saying that you may want to use Humminbird if you have Ultrex except for Garmin for Livescope; you might have to upgrade the Ultrex to i-Pilot Link to take full advantage. I have an old 360 (non-MEGA) that I use in combination with my Livescope on the bow, while I still have an old Humminbird 1199 at the console for sidescan and maps. If you think that you want to go Garmin Force for the trolling motor, then you might want to be heavier on the Garmin fishfinders and still leave the M360 on the bow. I see nothing wrong with keeping both brands, since there is some value to getting a 360 scan of you position that you can't get in other ways other than maybe 2 LS/AT/MLive used simultaneously.
