JW Fishers Mfg. was founded by the late Jack Fisher in the 1960’s. The brand was founded on handheld underwater metal detectors, but quickly advanced into a full array of underwater search equipment. Today the line of product includes hand- held and boat-towed metal detectors, magnetometers, under- water HD video systems, ROVs, sonar systems, acoustic ping- ers& receivers, pipe & cable trackers, a sub bottom pro? ler system and the Pulse 8X underwater metal detector.

JW Fishers designs/manufactures all of its underwater search systems at its factory in the USA. In 2022, the company intro- duced the 450/900 kHz Side Scan Sonar System. Building on over 30 years of sonar experience, CHIRP sonar offers the end user bene? ts over the conventional sonar such as longer-range operation and increased resolution. Fishers’ new SONAR

VIEW 2.0 software gives the operator complete control over the side scans operating parameters, ease of use and added features, while still allowing ? exibility in scan ranges and color schemes. The main features of the updated software in- clude increased touchscreen functionality, easier user interface and a modern feel. With included GPS positioning hardware, coordinates are automatically captured in the data. Move the mouse on a target, and position coordinates are displayed on the screen. Annotations can be added to images and stored. All ? les are stored in the industry standard XTF format for view- ing and playback 50 September/October 2022
