I have a Matrix 12 on my boat and just ordered a 798 si unit. they will be mounted next to each other.
I have heard that they can be connected so they share info. But I don't know what info would be shared and what benifit it would be?
BTW, I read something about SI unit needs different trans for high speed, but I am not sure my (mat 12) transducer will work with it..??
