As far as I know, you can't link one transducer to two display units. Each one needs its own transducer.
I have often wondered how this works when you have two completely separate systems on a boat, one in the stern and one in the bow. Why don't the two transducers interfere with one another? For example, wouldn't the bow transducer pick up the echo sent from the stern transducer, and vice versa? To avoid this I'm sure they have come up with some kind of encoding system so each unit sends out a unique code embedded in its signal, and only displays readings when it receives an echo back containing that same code. This would be a way for each fishfinder to be uniquely identifiable. That would explain why each display unit must have its own dedicated transducer. They only know how to read echos from the pings they personally send out.
I may be completely wrong, but this is my best swag.
