L-3 Klein Associates, Inc. announced today that its System 3900 dual-frequency side scan sonar system was successfully used by Halifax-based Wreck Hunter Incorporated to locate a Cessna 414 airplane off the coast of Nova Scotia. The L-3 Klein sonar system is an extremely high-resolution digital sonar for use in search and recovery missions that require a portable side scan sonar capability.
The System 3900 is designed to support dual frequencies, with a 445 kHz frequency that offers excellent range and resolution, and a 900 kHz frequency that offers higher resolution of identified targets. Wreck Hunter sonar operators used the low 445 kHz frequency to cover a swath of area 150 meters wide to locate the aircraft’s fuselage, which was identified in 52 meters of water 11 kilometers off Glace Bay, Nova Scotia.
"Both the Royal Canadian Mounted Police (RCMP) and on-site Transport Canada officials were very impressed with the quality of the images from the Klein System 3900, as well as its portability and ease of operation," said Terry Dwyer, operations manager for Wreck Hunter Incorporated. "In less than one hour, the system was set up onboard the RCMP Patrol Vessel Preventer, and we were fully operational to survey the targeted search area."
"The ability to quickly mobilize and deploy equipment, and to locate and identify critical assets and items of interest underwater was one of the main drivers in developing and bringing to market our System 3900 for search and recovery," said John Cotumaccio, president and general manager of L-3 Klein. "This is another example of how the system's superior underwater imaging capability and ease of use have made the product such a success."
