Product Summary

Klein is the pioneer, and only Commercial-Off-The-Shelf (COTS) sonar manufacturer that employs multi-beam side scan sonar technology, the advantage of which is near photo like images of the sea bottom. Unlike single beam side scan sonar systems, whose along-track resolution degrades with increasing range the Klein dynamically-focused, multi-beam side scan sonar systems deliver constant along-track resolution, with 100% bottom coverage, at tow speeds that are two to three times higher than possible with single beam systems.

Designed to address the demanding requirements for search and recovery operations, The Klein System 3900 is heavily utilized by police, fire departments, port authorities and surveyors across the globe. This competitively priced solution utilizes Klein's high frequency 455/900 kHz transducers for optimal range and image performance.

Its lightweight, compact design is one man portable, with the ability to be operated from a smaller boat for rapid deployment. The standard system is configured with a portable splash proof transceiver processing unit (TPU) and 50m of lightweight cable.
