Hi, Hoping for some info as many of you fish and presumably use fishfinders. I have had problems with my humminbird wide paramount fish finder. The screen was very sharp and detailed until "something" happened and the image of the bottom became blurred and there is alot of false readings from the bottom to the surface. They sent me a new unit thinking it was an internal voltage problem. That did not solve it. So, I'm down to either a bad transducer, bad wiring, or both as possibilities.
