Beam
The Beam parameters are accessed from the Horizontal menu.
The Beam command enables you to select the vertical beam width
in the horizontal presentation. The beam selection can be made
manually , or controlled automatically by the selected range.
The Wide beam is designed to be used with shorter ranges in
order to obtain a larger vertical coverage. This makes the sonar
less “tilt dependent” in the catching phase.
The Normal beam is designed to be used for the medium
ranges.
The Narrow beam is provided for the longer ranges. The
focused narrow beam has the highest source level, which
increases the detection range.
(A) = Wide (B) = Normal (C) = Narrow
In the Auto mode, the beam will change automatically defined
by the range selections made by the Wide and Normal buttons.
