For over thirty years JW Fishers has specialized in the design and manufacture of reasonably priced, high tech underwater search equipment. The product line includes diver-held and boat-towed metal detectors, marine magnetometers, underwater camera systems, ROVs, and side scan sonar. The company was founded in the mid-sixties by current president and CEO Jack Fisher. It all started when Mr. Fisher, an avid diver, needed an underwater metal detector to use on a salvage project. Finding there was no such product available for recreational divers, over several years he developed and built his own underwater metal detector. JW Fishers Mfg. was formed and Mr. Fisher began offering his detectors for sale to other recreational divers. As a result of customer requests for a line of commercial quality detectors, the company designed and built more powerful models that could cover larger areas. The product line was expanded from diver-held metal detectors to boat-towed metal detectors and magnetometers. Underwater cameras were a natural follow-on to the product line: customers wanted a tool they could use to look at targets they were finding with their boat-towed detectors or they simply wanted to do a visual search of an area. Next came a family of sonar devices including a line of side scan sonars ( the ultimate underwater search system ). Fishers side scan sonar is a breakthrough in a high performance, low cost side scan systems. Today the company maintains an active R&D effort to explore and develop new technologies for underwater search in order to offer our customers the latest and most cost effective equipment available. The company offers the most complete line of underwater search products from any single manufacturer and stands behind every piece of equipment with a warranty and service that is second to none.
