Thanks for the very detailed explanation. I couldnt get my 1 of 2 HDS lowrance unit to show colors. Then you mentioned you have to do it on both finders. Thanks for the great information.
I just watched 3 or 4 RU-vid videos on how to do it so I knew what I was doing when I got into the menu section. So far, it allowed me to get into menu, more options, chart options... but it does not have "shading" listed when I scroll down. That is the next step, but it is not showing up on my screen when I try to scroll down. Any suggestions? Thanks so much if anyone has any advice. 👍👍
