Hi, I did a search and could not find the issue that I am having. I have a Helix 7 chirp,mega,si gps Gen3. I am having a clarity issue. I purchased this unit new a couple of years ago and have not spent a lot of time on the water using it as much as I planned. When I first received the unit, it was defective and I had to send it back for repairs. It has worked ok but has never had the clarity as my previous brand. I have watched all the videos on how to properly adjust your Humminbird but still no luck. I was out a few days ago and it went completely stupid. The screen was a complete mess. I worked with the contrast and sensitivity, but no luck, so I reset it to factory defaults. It would start out working somewhat ok, then cloud the entire image as shown in the attachment's.
