Humminbird 515 - Manual (Page 23)

Slanted layout: This layout presents the two 455 kHz side sonar beams and the
200 kHz down-looking sonar beam as three panels of historical data. This layout
is presented as three slanted panels. New information appears on the right,
and scrolls to the left.
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.
