terrova sonar

[rnvinc]

I have DI and SI on my dash mounted helix which reads off my transom transducers. On my bow mounted helix I have sonar gps. It reads SI and DI through Ethernet but I like the 2d reading off my terrova when trolling

Move the console unit up front and test the US2 connected directly to it ... to verify if the US2 is defective ...
