The Sidescan view is a Sidescan picture generated from the sonar data received by the system.
The display is drawn on the screen as a waterfall – the newest information appears at the top of
the screen, while the oldest falls off the bottom of the screen. This is similar to the way sounder
displays operate, except that in their case the new data appears on the right and the old data
disappears off the left of the screen.
The left side of the Sidescan view shows the signals received from the port side while the right
shows signals received from the starboard side. By default, the Sidescan view starts at the
centre of the vessel and works its way out to port and starboard.

ground gives strong returns (lighter on the grey scale), while a patch of mud or kelp causes a
dark patch/shadow to appear. See “Figure 34. Sidescan View”
The primary advantage of the Sidescan view over the other views is in locating and identifying

transducer that is held deeper in the water, having the advantage of a lower aspect ratio.
