Humminbird Side imaging on Pickwick Lake
Here is another picture later in the day and I had switched to amber2 in order to see the screen in the sunshine. This picture is a very good example of fish suspended very high in the water column in the narrow green rectangle. Notice in the corresponding green square the fish have created a sonar shadow that is a long way to the side and long shadows. This tells me the fish are just under the surface.
Jackpot is the tall stump just off the drop. This stump is 4 feet tall and has a nice diameter. The cursor is the actual stump the dark portion is the sonar shadow created by the stump.
