Discover What Lies Beneath

Side scan sonars are one of the most sought after, and effective tools for underwater searches. The reason; they can cover large areas quickly and “see” what’s on the bottom regardless of water visibility. A side scan finds things by sending out a sonar beam which sweeps over the bottom, reflects off any object laying on the bottom, and returns to the towfish.

Visual Display Reports Detailed Analysis

The received signal is sent through the tow cable to a topside display. The displayed image is a highly detailed two dimensional picture of the ocean, lake or river bottom and any objects lying there. The sonar beam is transmitted and received by transducers mounted on each side of the towfish. How the transducer is constructed determines the frequency of the sonar beam. Side scans with low frequency transducers have excellent long range capability, but low resolution. High frequency systems have high resolution, but very short range. A dual frequency side scan has high and low frequency transducers to give the best of both systems; long range and highly detailed images.

Discover JW Fishers Side Scan Sonars

JW Fishers sonars represent a major price/performance breakthrough in low-cost side scan systems. Fishers offer three different frequency side scan systems; the SSS-100K, the SSS-600K, and the dual frequency system SSS-100K/600K. The SSS-600K has very high resolution over ranges of up to 200 feet (400 foot swath). This system is ideally suited to search for small or soft targets. Applications for this system include: searches for old wooden wrecks, scattered debris fields, ghost nets, logs, drowning victims, mine countermeasures (MCM) by the military, and a variety of other targets. It can also locate larger targets such as sunken vessels at ranges of up to 200 feet. The SSS-600K is in use by law enforcement agencies, dive rescue groups, and military units worldwide.
