It just seems to me that if I am sitting in the same spot and turn the unit off and back on, I should see relatively the same image. Shouldn't see way more noise after turning it off and back on. And selecting medium on noise rejection shouldn't change anything if medium is already selected. Lowrance support gave me a couple of things to try that I am going to try while on the water this weekend.
