Just noticed this recently. I thought it was the recent update but when I shut my motor off it goes away. I'm getting horizontal lines on side scan when the motor is running. It has to be electrical interference. Is there a way to get rid of this? It does not happen when the motor is off and I'm running my Ultrex. Any kind of isolators I can run? I don't want to re-wire my units to run off the trolling motor.
Thanks in advance.
