Simrad FS80

Next generation cost-effective trawl sonar for gear monitoring

How do you take a reliable, easy-to-use, cost-effective trawl sonar like the FS70 and make it even better? The answer is the Simrad FS80.

Both smaller and lighter than the FS70, the FS80 is designed from the ground up to be even more robust, versatile, and feature-rich. The FS80 features a net profiler with multifrequency capabilities to accommodate different types of fisheries within a single sonar.

Robust, versatile, and feature-rich

Both smaller and lighter than the FS70, the Simrad FS80 is designed from the ground up to be even more robust, versatile, and feature-rich. The FS80 features a net profiler with multifrequency capabilities to accommodate different types of fisheries within a single sonar.

In addition to the net-opening view provided by the single-beam sonar, up-sounder and down-sounder views are also included. Two down sounders monitor the footrope, the sea bottom, and fish entering the net. The up sounder monitors the headrope and fish escaping above the net. This combination of sonar and sounders allows the operator to see the complete net opening, including individual fish targets in the vertical plane, the fish/school location, the bottom/net location, and the net geometry.

Pitch and roll sensors are integrated

Pitch and roll sensors are integrated into the headrope unit to monitor the position and orientation of the FS80 in the water. We have also included depth and temperature sensors. These sensors monitor the environmental conditions and the physical position of the FS80 in the vertical water column. In addition, a catch hydrophone within the Headrope Unit can communicate with your Simrad PI catch sensors. The FS80 provides real-time information from the sonar and associated sensors to the bridge, maximizing fishing efficiency and reducing sea time.

Operates reliably on both poor and good-quality trawl cables

The Simrad FS80 operates reliably on both poor and good-quality netsounder (third-wire) trawl cables. For this reason, the FS80 is the perfect upgrade if you want to upgrade from the FS70 Trawl Sonar without upgrading your existing cable.
