Adding a panoptix tranducer to a da-ducer stick on the front of one of my boats. It will have to be networked into a 1040XS. Thinking the PS-22 will not work with the older unit and must use the PS-21. Because on this boat, have a PS-31 shooting on the transom, will have to disconnect and reconnect it when using a particular transducer.
Help me out....with any thoughts
