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 in the longer ranges.
This beam operates with higher source level, which increases
the detection range.
(A) = Wide (B) = Normal
In the Auto mode, the beam will change automatically as
defined by the range selections made by the Wide button.
The following selections can be made:
Wide - This button is used to select the upper range for the wide
beam width in Auto mode. For ranges higher than this selection,
the beam will automatically switch to Normal.
