New hummingbird fish finder install and having big issues
Installed a hummingbird 859xd
Take it out and works like a charm and as soon as we hit 50fow it just can not track bottom or get display any reading back
Odd thing is when I turn it off and turn it back on it will read the depth even in 200fow for about 3 seconds and then cheap out again, so it clearly works then just messes up again.
This is both at dead still and trolling speeds.
Any clue what's going on?
