The 340 SERIES is a high performance
all moulded, dual frequency transducer featuring both
HIGH and LOW frequency sections combined in a single
unit.
Compatible with a wide range of echo-sounders the
piston elements are configured to achieve optimum echo-sounder
performance.
The
ability to specify a wide combination of frequencies
in the same basic unit, provides the echo sounder
manufacturer and operator with the flexibility
to configure a system and beam pattern to match
the desired survey requirements of resolution,
range and silt penetration.
The NEPTCAST® polyurethane
housing provides a mechanically robust, corrosion
free transducer, suitable for hull or over-side
mounting.
