The Tech
JW Fishers has continually evolved its underwater search systems. Fishers designs and manufactures all of its underwater search systems at their factory in East Taunton, Mass. Its line of equipment includes hand-held and boat-towed metal detectors, hand-held and boat-towed magnetometers, underwater video systems, ROVs, side scan sonars, scanning sonars, acoustic pingers and receivers, and pipe and cable locators. Fishers continues to expand its line of acoustic systems with the recent addition of transponders and an interrogator. These devices are used to mark the location of underwater objects or oceanographic instruments. The key advantage of the transponder is its ability to lie silent on the ocean bottom using almost no power until activated by the interrogator to begin transmitting a signal. The newest acoustic products to be added are low frequency pingers. Available in both single and multifrequency versions, the low frequency pinger can be detected at a distance of 3 to 6 miles, compared to a few thousand few for standard pingers. The company is also constantly updating and improving the software used with its sonar systems and boat-towed detectors, adding new features and capabilities, and making the equipment easier to use and more powerful.
Another new product is the CMS cable management system which makes it easier to handle long cables.
