For more than 40 years JW Fishers Mfg has specialized in the design and manufacture of high-tech, reasonably priced underwater search equipment. Its side scan sonars, underwater metal detectors, ROVs, and magnetometers are in use by commercial diving companies, public safety dive teams, law enforcement agencies and military units worldwide. In 1971 JW Fishers began manufacturing underwater metal detectors for recreational scuba divers. Demand grew and commercial diving companies and police departments began asking for other types of underwater search equipment. In the late 70’s Fishers expanded its product line to include boat-towed detectors, video systems, and ROVs. As knowledge in these technologies grew, the company expanded its R&D into sonar. As computers became smaller and more capable, they allowed development of powerful, low cost sonar systems. Today Fishers offers three side scan systems employing the most commonly required frequencies, 100K, 600K and 1200K. Low frequency provides long range but lower resolution, high frequency gives the highest resolution but shortest range, and the middle frequency provides an optimal combination of both.
The Tech
Since its inception 40 years ago JW Fishers has continually developed new and better underwater search systems. The company offers one of the broadest ranges of products in its industry. Fishers designs and manufactures all of its underwater search systems at their factory in East Taunton, Massachusetts. Its extensive 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. 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.
