ACTIVE SONAR USAGE
6.2.8.1 Coverage Angle
The benefits of the variable swath feature are twofold:
 Increased sounding density in a small sector may be used when tracking pipes or other
linear features, where the operator is not interested in data outside a defined sector.
The increased sounding density helps define small targets.
 A reduced swath width allows an increase in ping rate for any given depth.
6.2.8.2 Beam Reduction
 With beam reduction enabled, only the beams necessary to fill the given swath are formed.
 With beam reduction disabled, all beams are compressed into the selected coverage angle.
