Fishing today and my 777c2 just rebooted never done that before. 1197 keep right on working, voltage reading on 1197 at the time was 12.4.
When 777 started back up all was fine, it and the 1197 showing all information pretty much the same

This ever happen to anyone else?? If so what was the problem?

Oh I was trolling with the trolling motor, but never even had any motor noise on the 777??
