I bought a HDS9 GEN2 Touch and mounted the Sonar on the trolling motor and the structure scan transducer on the bow. I am going to mount another transducer on the stern for the structure scan so I can switch to either transducer. I would like to know if there is a switch-over device for such a configuration (which I doubt). I plan to make one in the event there is no such device. I am also interested if there would be any problems with switching from one transducer to another? I would guess that the unit would have to be turned off with nothing electrical on before switching transducers. Anyone have any thoughts on possible problems?
