So I bought my husband a bass boat for father's day. It had a Lowrance fish finder on it. We call Lowrance and warranty ran out last year, so we looking for someone to help us fix it. You can turn it on and it work but after about ten minutes the buttons stop working. One of the reasons I bought the boat was because he like the fish finder on it. Very disappointed in the way things have worked out so far. Some please Help!
