You never know. Don't want to discourage any body. Like I said, I had marks - and different marks - top to bottom all over my fish finder so something was there but not hungry. Mine isn't the newest and highest tech but it does show various sizes of fish. Last time I saw that many marks on it was one evening last fall, when we caught maybe 50 walleye shorts in about an hour of casting. Imaging too that the heat will be brutal out there about mid day.
