JW Fishers Scanning Sonar Scan-650

Scanning Sonar Scan-650 by JW Fishers

Sonar scanning generates a picture of the undersea environment independent of water clarity, making it an ideal instrument for the underwater search. It accomplishes this by emitting a sound wave that is reflected by items on the ocean floor or in the water column. The returned wave is received by the sonar head and transmitted to the surface for display. The image of the reflected sonar is displayed on a laptop computer. The SCAN-650 scanning sonar from JW Fishers facilitates your work. Model A is for big ROVs, whereas Model B is for tiny ROVs. Both variants include the surface sonar processing module.

Sonar scanning provides a "portrait" of the undersea environment independent of water clarity, making it an ideal instrument for the underwater search. It accomplishes this by emitting a sound wave that is reflected by items on the ocean floor or in the water column. The returned wave is received by the sonar head and transmitted to the surface for display. The image of the reflected sonar is displayed on a laptop computer.

Fishers SCAN-650 is a high-performance scanning sonar system that can be put on an ROV or used from a small boat in shallow water when pole-mounted. The scanning sonar functions as an obstacle avoidance and target identification device. The sonar beam sweeps in a 360-degree circle (or a subset of 360), allowing any item inside the sonar's "field of vision" to be viewed on the computer monitor. In common use, the sonar head or transducer is installed on top of a remotely operated vehicle (ROV). The head "sees" targets in all directions, even those well beyond the camera's range. The topside computer displays the sonar pictures.

Package Includes

Using the sonar for direction bearings, the operator navigates the ROV to various targets for identification and video recording. Along with the GPS location, time, and date of the vessel, scanned data files are kept on the hard disk of the computer. The recorded files are available for playback at any time. Software is given for data post-processing, including file editing and merging. Small file parts, such as screenshots, can be extracted and emailed as a compact file. The program includes a tool that enables the operator to decide the size of the on-screen targets. Included in the system package is the sonar head with "downstairs" electronics, cable, surface sonar processor, software, and A/D board for your computer. The A/D board considerably reduces the time required for data transfer to the computer, hence increasing the sweep rate (takes less time to complete each sweep). Fishers SCAN-650 is durably constructed for commercial use.
