Hey guys I was on the water yesterday trying out my new Eagle Cuda 168 fishfinder but I noticed that we had no visible fish arcs appearing on the screen however the depth part and everything else was working normal.
I was thinking maybe theres 2 possible reasons, a) could it be because we wired it to a 12 volt car battery? (does it ahve to be a marine battery?) or b ) We were too shallow, we were around 10 feet. Any Input would be appreciated.
Oh and one more thing when I tuened on fish ID, it was working, but no fish arcs hmmm.
