6-Beam Sonar View - Humminbird 748 3D Operation Manual

6-Beam Sonar View

6-Beam Sonar View displays information from each of the six 455 kHz beams
in a traditional 2D representation. This view displays the raw sonar returns from
each of the beams that are used to create the 3-dimensional wire frame
representation of the bottom in the 3D Sonar View. This view can be used for
identifying structure on the bottom and sonar returns in the water column.
• Sonar Targets: The 6-Beam Sonar View also provides information on
sonar targets relative to the boat. The far right window displays sonar
targets which are to the far right of the boat and the far left window
displays sonar targets which are to the far left of the boat. The
remaining windows display sonar targets which are successively closer
to the boat. The width of coverage is approximately equal to the current
depth.
• Digital Readouts in the 6-Beam Sonar View cannot be customized,
making information such as water temperature and voltage unavailable
in this view.
