Thread: Anybody use a lowrance Hook2 4x fish finder

Run a separate ground wire to the unit from the battery if not already

I really appreciate all the help. I have made some progress but it still isn't right. I got the Temp and Voltage working now, but the depth isn't reading/or showing. Made some changes and have it ran to a single battery all by itself. Not the trolling motor battery as before.
I've tried to set a hard limit on Custom setting and still it doesn't show depth. I am about ready to chunk this thing and try another unit. Life's to short to set and deal with this frustration.
Went out again yesterday, Wind was big issue, but did manage 3 decent size Crappie. Enough for Dad for supper.

Thanks again for everyone's input
