I had a chance to make a fishing trip yesterday with a good friend from work yesterday for crappie and shellcracker. We caught a lot of fish on small 1/16 oz. leadheads with Bobby Garland Baby shad lures. As you can see from the photos, the first one shows a school of feeding stripe (yellow stripe & a school of shellcracker). These images are a snapshot from my Hummingbird 1158 HD Down Image. Hope this helps you to understand your images on your units.
