Can you share transducers with 2 HDS 5 connected together.

Friend told me that he got a new boat with two HDS 5 units. He told me that they told him he could view both transducers at the same time in split screen. I have a 520c and a 28c linked and I can't see both transducers. Is this possible??

Not to my knowledge, but you can switch between the different transducers if connected via ethernet. Ask Medic, he knows everything.
