I am having issues with my Helix 7 DI unit. Worked fine until this weekend, but all of a sudden the DI image is junk and has very little definition. The 2D sonar seems to be a little less clear as well but still worked OK. No settings have been changed since the last time I used it so I am leaning towards a transducer issue. No impact marks on the transducer but I may have moved it a touch accidentally. I have only one screw in it to adjust it as I am still not happy with the high speed picture. It is close enough to have a decent picture. I have a Helix 5 up front I could hook up for 2D, but it is not a DI unit. Thoughts? Anyone seen anything close to this? Thanks!
