Klein Marine Systems, Inc.

Salem, New Hampshire www.KleinMarineSystems.com

Founded in 1968, Klein Marine Systems, a wholly owned subsidiary of Mitcham Industries, Inc., is a lead- ing supplier of side scan sonar equipment, waterside se- curity and surveillance systems. Klein Marine Systems introduced the ? rst Nadir Imaging Sonar for AUV/ROV vehicle manufacturers in an innovative, stand-alone nose cone con? guration. The µMA-X is a highly scal- able modular component which integrates its custom ? t nose cone easily to the current AUV/ROV vehicles.

The µMA-X is powered by the Klein BLUE technology providing superior imaging performance with the same interpretation characteristics equal to Side Scan Sonar.

The µMA-X can be scaled to accommodate both larger or smaller diameter vehicles. The Klein µMA-X when

JW Fishers Mfg., Inc. paired with Side Scan Sonar will provide a 40% increase in survey ef? ciency, provide complete NADIR coverage

East Taunton, Mass – www.jw? shers.com and is compatible with ATR systems. The Klein µMA-X delivers ef? ciencies in survey time, reduced power con-

JW Fishers was founded in the mid-1960s by Jack Fish- sumption in a compact, low-power and neutrally buoy- er, an avid diver who needed an underwater metal detec- ant modular system. The µMA-X is easily integrated tor to use on a salvage project. Over the next several years into any vehicle and includes an Internal Motion Sensor he developed and built his own, and as a result of custom- which eliminates the requirement to integrate to the ve- er requests for more powerful models that could cover hicle sensor, providing redundancy. The system uses the larger areas, the company expanded its line to include vehicle data input via the Ethernet with a simple, non- boat-towed metal detectors and magnetometers. Under- proprietary NMEA data link with the vehicle.

water cameras were a natural follow-on to the product line: customers wanted a tool they could use to look at targets they were ? nding with their boat-towed detectors or they simply wanted to do a visual search of an area.

Next came a family of sonar systems including scanning sonars and side scan sonars (the ultimate underwater search system). Acoustic pingers were added as a way to mark the location of underwater sites and oceanographic instruments. Cable and pipe trackers followed resulting from customer demand for easy to use instruments that could ? nd deeply buried pipelines, electrical lines, and ? ber optic cables. JW Fishers both designs and manufac- tures all of its underwater search systems at its factory in the US. In 2019 JW Fishers upgraded its entire video line to 1080p HD cameras. The upgraded systems range from a boat towed video system (TOV-2 HD), to a dropped video system (DV-2HD), a mini camera system (MC- 2 HD) and a Diver Held Camera system (DHC-2 HD).

Also available is the Video Recording Monitor (VRM-2

HD) totally redesigned that displays and records video in 1080p HD format, has still picture capability and the ability to add audio to the recorded ? les.
