Low-frequency acoustic signals provide superior sub-bottom signal penetration vertically through coarse sand, gravel tills, and other difficult-to-penetrate sediments. Small component size, portability, and low power requirements make this a valuable tool for any survey platform.
FEATURES/BENEFITS • Narrow-band 400 Hz acoustic pulse provides bottom penetration through many sediment types • Rugged, lightweight transducer platform provides stable operation in adverse sea-state conditions • Flexible portable transceiver unit optimizes system for a wide range of sediments - User-selectable trigger or external trigger - Low-noise pre-amp with high/low pass filters and gain control • Portable power supply operates from 110 or 220 VAC of less than 1 KiloWatt • Oil-filled hydrophone streamer cable incorporates a 7-meter multi-element active section • 35-meter deactivation switch
