The Klein System 4900 is a versatile Side Scan Sonar that can be used for many different survey and recovery applications. The high-fidelity, high-definition imaging abilities and the portability of the System 4900 make it an ideal tool for Search and Recovery (SAR) missions while its rugged construction, selectable frequencies and 300 m operational depth rating provide superb capabilities for the coastal survey and security communities.
The System 4900 employs both a user selectable CW pulse transmission mode and advanced broadband CHIRP signal processing technology which, when coupled with Klein's proprietary de-speckling algorithms, provide extraordinary long range, high-resolution seafloor images. Image quality is further improved by the System 4900 transducer designs which are optimized to provide very narrow horizontal beamwidths and thereby exceptional along-track resolution. The combined result of these discriminating features is high quality image resolution at low frequency long ranges that is comparable to or better than high frequency, short range resolution images of competitive systems. When sonar detail and range is important, look to Klein for the solution!
The 455/900 kHz provides long range detection, 200 m per side at 455 kHz, and high definition images for classification to 75 m per side at 900 kHz. The digital telemetry system of the System 4900 can drive up to 1000 m of armored tow cable. The System 4900 towfish does not require an optional keel weight for submergence; it has been designed to provide portability, submergence and optimal stability at all depths to a maximum of 300 m.
