In all of these layouts, the sonar information from the side-looking beams reveals bottom contour, structure
and fish similar to the down-looking beam, but the area covered is to the left and right of the area shown
in the down-looking portion, so you actually see more of the bottom. The distance covered by the right and
left beams is based on the depth setting for the down-looking beam, up to a maximum of 160 feet.
