Humminbird Down Image – Stumps, Piers and Bass

In this screen shot from my Humminbird Onix I did a Down Image of a pier along a deep cove. In the photo you can clearly see the pier post, a couple of stumps and bass suspended under the pier and  few bluegill hugging the bottom. When I scan using my Down Image I always use the 800 kHz settings to get a clearer detail image then I get with the 455 kHz setting.
