Well, I know where you are talking. So I guess I just need to take the time to search and watch the electronics..I often see large bottom marks like boulders here and there. You have to be quick on the way-point button to keep on them. Pretty cool on the spud bar. I have not heard of anyone fishing ice out that way for a long time rarely freezes up good East of the islands. It must have been there a long time. Thanks.
