Rickie, yes a new unit and a new transducer and I hang the transducer over boat. I did in April try unit on friends boat and did better still did it and put his unit on my boat and only did it a little. I check my wireing and it and my 2D are wired straight to battery. In a few days I will put a battery that only to that unit and not to big motor even though I cut engine and 2D unit off and tried it setting still. Out of idears. Will let you know next week. To me it don't make sense.
