4.3.1 Beam Mode
It will depend on the
license which beam modes
are available.
The beam mode can be switched on the fly. For the beam mode the
following modes can be selected:
Equi-Angle
In equi-Angle mode the spacing between the beams is equiangular.
The beam center-center angular spacing is constant across the swath.
In areas of significant relief and in particular when surveying features
such as wrecks and vertical structures such as harbor walls, Equi-
Angle should be used in preference to Best Coverage (see also Best
Coverage). When the ‘Custom’ checkbox is ticked the number of
beams can be set by the operator.
This allows the operator to be able to capture the highest detail using
the highest beam density needed. In very shallow water less beams
can be used to reduce data volumes.

Intermediate
Is made for a general purpose survey operations and provides high-
density soundings over the entire swath using the maximum number of
beams. When the ‘Custom’ checkbox is ticked the number of beams
can be set by the operator.
