The preamplifier provides a 7Hz high-pass filter and an insert-voltage calibration facility, but does not allow the hydrophone to be used as a projector.
The hydrophone is built to withstanding high static pressure, the operational upper limit being 107 Pa (100 atm / 1000 m (3250 ft.) ocean depth.
An integrated watertight connector allows quick disconnection of the cable and makes replacement and storage very easy.
