See what Lies Beneath

Scanning sonar is an ideal tool for underwater search because it produces a “picture” of the underwater environment regardless of the water visibility. It does this by sending out a sound wave that reflects off objects on the bottom or in the water column. The reflected wave returns to the sonar head where it is received and sent to the surface for display. The reflected sonar image is displayed on a laptop computer.

Advanced Scanning Sonar

Fishers SCAN-650 is a high performance scanning sonar system that can be mounted on an ROV or pole-mounted for use from a small boat in swallow water. The scanning sonar serves as an obstacle avoidance system and provides target identification. The sonar beam sweeps in a 360 degree circle (or any portion of 360) allowing any object in the sonars “field of view” to be seen and displayed on the computer monitor. In a typical application the sonar head or transducer is mounted on top of an ROV. The head scans a circle around the ROV and “sees” targets in all directions, including those that are well beyond camera range. The sonar images are displayed on the topside computer.

Designed for Commercial Operations

The operator, using the sonar for direction bearings, drives the ROV to the various targets for identification and videotaping. Scanned data files are stored on the PC’s hard drive along with boat’s GPS position, time, date, and other pertinent data. The recorded files can be played back at anytime. Software is provided to allow post-processing of data including editing and merging of files. Small file sections, including screenshots, can be edited out and copied to a small file for emailing. A sizing tool is included in the software which allows the operator to determine the size of the targets on the screen. The system package includes the sonar head with “downstairs” electronics, cable, surface sonar processor, software, and A/D board for your computer. The A/D board significantly improves data transfer time to the computer which increases the sweep speed (takes less time to complete each sweep). Fishers SCAN-650 is ruggedly built for commercial operations.
