Just what are you wanting to see?. Sonar is 1/3 of depth. So in 3ft,, you see a circle of 1ft. In these depths, you prolly are spooking any fish that is under the sonar ducer,,, and not because of a 'tickin' noise. Your shadow,, & banging the bottom, even in 'dirty' water is prolly spookin. Use your 'structureScan' out from where you are fishin. Find their holding depths. Then spider rigg them. <*)}}}><
