It could be that the transducer is starting to go bad. Try testing it on another Humminbird transducer, like possibly the one you got with your HELIX 5 unit (if it is not the HELIX 4 DI or HELIX 5 DI-GPS model) and see if it does the same thing.
I have a Humminbird 586c HD unit at the bow. I moved it there when I got my Helix 5. I have used it at the bow now for over a month without any issues. Sunday it started showing a thick green line at the 2.5 ft depth range. The line resembles surface clutter but it is at the 2.5 depth range no matter how deep I am. I have the surface cluuter turned all the way down and I never have any surface clutter on my screen(just my preference). Does anyone know what this could be. Thanks in advance.
