What did I do? Is it a damaged transducer, interference or a setting issue? This blue streak starts at the 1.5' depth setting for my trolling motor depth and goes to 2.5'. This image is from my garage so that is why the screen is white. I added an on the water image but the blue bar is harder to see. It's a Helix 7 with a XTM 9 DI 25 T transducer.
I t is only on the sonar and not down imaging.
