most rigs I've seen use two units. one in the front of the boat mounted on the trolling motor and the other hard mounted to the back.
I have found when trolling it is more important to have the transducer up front.
drifting side ways down river, mounted front and back works best and you need them both at the same time to cover unknown terain. It also helps to know wich side the fish are on as well. "done a lot of side ways drifting"
the best thing is to find a second unit at a garage sale. If you cant find that just leave your self enough cable where you can switch cables on the unit.
having some one build you a junction box will cost as much if not more than picking up a used unit.
to build a junction box, you will need two female receptors and one spare male counter part with cable and one toggle switch. Those parts are pretty hard to find except on old units, Hence if the old units are working, put them to work.
true you can cut the cables of the transducers, but you will short suit your self if you ever are in need of having to sell something for a quick buck.
