I am running a Helix 12 Mega imaging with the chirp transducer that came with it. I can't get an image in down imaging. I've messed with the settings but can't seem to figure it out.
I have the Helix 10 hook up to the transducer on the trolling motor and it seems to read the images just fine.
The 2 graphs are networked together.

Any advice?
