Not a waste at all. I was seriously into kayak fishing for 4 years. During that time I owned 5 different models. I had an HB 899 si that I used on all of them. I gave up kayaking due to no longer being able to lift them onto the trailer.....one of the last ones I had weighed 76 pounds and having had both rotator cuffs repaired I cloud no longer do it. The si unit put me on a ton of fish those 4 years. I got back into boating and purchased a HB Helix 10 si Mega. If I still had a kayak I would mount it to it. It makes it easy to find bedding sunfish and also I learned to identify sunfish using the down imaging as well. It will put you on fish and save you a lot of time. Here are a couple of images....one is obviously of bedding fish and the other is in early winter....tons of bluegill. Fish pics where they were all found with si unit.
