The Dr. does. This is extremely relevant to a like like Cumberland.
I do! I do!! I disagree that the dead zone is as much of a factor as some make it out to be. The dead zone can happen when the graph reads a higher contour on the bottom and doesn't return a drop off, crack or crevasse that is lower. It could be a factor with a single frequency sonar and, in my opinion, only if you are settings still. But multi scan, CHIRP, or moving all negate the dead zone. As you move, the deeper area is scanned and all is right with the world again. LOL FYI, I have settled on Medium Chirp and love it. I do not get the finer definition but I've learned to read what is returned. Stripernut hit on another tip... There is no set it and forget it. I use my downlines as my guide. I set my sensitivity and contrast so I can always see my weights and my baits. That's my fastest way of making adjustments. I may fine tune a tad more but that always gets me in the ballpark.
