Side-scan sonar for Search & Recovery
L-3 Klein has recently completed the design and development of a Model 3900 side-scan sonar. The system is high resolution digital sonar for use in Search and Recovery missions which require a portable side scan system. The model has a dual frequency capability with 445 kHz offering excellent range and resolution and 900 kHz which offers higher resolution of identified targets.
The system is configured to operate by one man from a small boat in shallow water. The standard system configuration includes a splash-proof Transceiver Processing Unit (TPU), custom configured laptop and 50m of lightweight tow cable. The Model 3900 Towfish electronics are housed in stainless steel body with a phosphorescent finish for easy underwater identification.
