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.
