Hello,
Can anyone tell me what the clutter or marks near the bottom of the screens may be caused from? They are constant, I know they are not fish or bait but I can't figure it out. Could it possibly be a density change in water or thermocline? Same on all 3 of my units and like I said is constant know matter where I am at on home lake but only appears like this in the about 16-22fow range. Iv'e been running the same set up for a few years and have never encountered this before. The only difference in the posted images is one pic is 50% sensitivity the other 60.
Thanks for any tips guys.
