I have a couple of questions for you out there. The first one is, is all the blue marks on the left screen some sort of interference? If so, what can I do to get rid of it?
Second, is this a brush pile on the bottom of the screen? If it is, I understand that there could be a large number of crappie (or other fish) in the pile, but in the one image are those all really fish? Also, why did the one image change to blue and red and look like the same kind of image as the other two. And lastly, the jagged white line on the bottom, does that represent the actual bottom or something different?
It has been a very long time since I have had any electronics. Thank you in advance for your input.
