I had the same issue with my Lowrance and LSS-2 unit on my first setup. The shallower the water, the less we could get with the side scan. Kind of raises a question as far as how shallow one can get to get effective and clear returns on the structure scan setup as far as side imaging. I believe we only made it to 8ft is the shallowest we went and the quality wasn't the greatest. Anything over about 10 FOW we had really good luck with, just the shallow depths weren't very good. Maybe someone here can chime in and describe a possible fix? That was one of the reasons I was really thinking about going with HB units for my new boat because the quality of the picture seemed to be a little clearer and the side scan seemed to be better in my book...but went back with lowrance instead because I am more familiar with the system. Sorry, got side tracked and off topic. Anyway maybe someone can come up with a reasoning or possible solution. Seen a gentleman on here by the name of Rickie I believe. Very smart in this field, maybe he will chime in with something. Ok I'm done ranting, sorry for hijacking your thread, best of luck bud!
