The Klein System 4900 is a versatile Side Scan Sonar that can be used for many different survey, search 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 despeckling algorithms, provide extraordinary long range, high resolution seafloor images.
Image quality is further improved by the System 4900 transducer design which is optimized to provide very narrow horizontal beam widths and thereby exceptional along-track resolution. The combined result of these discriminating features is a high quality image resolution at long ranges which is comparable to higher frequency systems. When sonar detail and range is important, look to Klein for the solution!
The System 4900 also features the new Smart Telemetry which measures the electrical parameters of the tow cable (including slip ring and deck cable) and selects data rate and filter settings that maximize data throughput. This results in continuous, high quality imaging over a broad variety of cable types and cable lengths, in excess of 7,500 meters of 0.68” equivalent cable. This feature is designed to support surveyors and rental companies who frequently switch equipment to different winches and different cables.
The 455/900 kHz provides long range detection, 200 m per side at 455 kHz, and high definition imagery for classification to 75 m per side at 900 kHz.
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.
