Lowrance HDS 7 gen 3

Sonar and sidescan work great for about the 1st hour of trips and then the scroll with stutter and freeze up. Repower unit and runs a few seconds and freezes. Tried factory restore and same issue. Back track install of earlier version that worked prior to issue and work a day then started issues again.

Check for interference
by: John

Check or consider electrical interference, what else is on when this happens? motor running, or trolling motor running? if so may need some form of suppression on power supply
