No, the StructureScan ducer is entirely separate. You will need two 2D sonar ducers. The typical setup is a 2D sonar ducer on the trolling motor, a 2D ducer as shoot-thru in the back, and a StructureScan ducer mounted on the transom or jackplate. With your units Ethernet-linked, both units can read your StructureScan ducer, but of course when viewing it at the bow unit, the view is from the back of the boat where the StructureScan ducer is. Each StructureScan will only support one ducer, so another option is to get a second StructureScan and have it's ducer on the trolling motor along with the 2D ducer.
