i recently upgraded my tm and electronics. i have a helix 9 gen2 at the helm. and a helix 5 gps/sonar at the bow thats connected to the universal sonar on my ultrex. i'm not happy with the returns i get with the US when i compare it to my bigger unit there is night and day difference. i think im gonna change this out to the transducer that came with the unit. my guestion is do i just unhook the adapter that i got to make it compatible with the US an just mount the transducer as you would with any other unit. just dont want to miss anything up unhooking.
