Humminbird 531427-1_D - Manual (Page 25)

18
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 90° beams is based on the depth setting for the down-looking beam, up to a
maximum of 160 feet.
