Single / Triple Beam Display
The Single / Triple Beam Display shows seafloor and water column information in a similar fashion
to the traditional fish-finder display. Signal returns are drawn vertically in slices, with new information
appearing on the right of the display, and old information dropping off the left side.
In Single Beam mode, only the middle beam is used to draw the information from the seafloor.
In Triple Beam mode, additional port and starboard beams are used to draw information from selectable
areas of the water column through configuration of the beam width and beam angle. See Figure 5.

This adjusts the angle which the centres of the port and starboard
beams are set from the middle beam. Larger angles move
the beams further from the middle beam, and smaller angles
move the port and starboard beams closer to the middle beam.

angle will therefore give a 50° swath for the Triple Beam view. See
Figure 6.
