I bought the Helix 7 chirp mega SI unit a couple of months ago and mounted on the bow. I did what any red-blooded American would do upon purchase; return the stock transducer(transom) and replace it with the shielded transducer for trolling motors.
I get great images, but on the Side Imaging, I cannot figure out how to change the colors.
I can change colors on 2D sonar and Down Imaging, but cannot on the Side Image.
There a passcode, like "Open Sesame" or something?
Thanks!
