Thread: HDS7 gen3 with HDI transducer

I'm wanting to put a hds7 gen3 on the bow of my boat and run a hdi transducer on trolling motor. This will give me 2d and downscan sonar. I want to know if my hds 9 gen2 touch is Ethernet to the hds 7 gen3 can I use my lss2 transducer at the back of boat to view side scan while also viewing downscan on the front transducer. May sound dumb but I would just like to search all around boat for structure while fishing and viewing my 2d and downscan at the same time.

The Lowrance units can only view one structure scan source at a time.
