Trawl Sounder

Advanced echo sounder

The TrawlSounder is an advanced echo sounder showing the height of the trawl opening, whether the trawl is on the seabed and the distance between the trawl and the seabed.

It also provides a simplified sonar that shows whether there is fish influx, and the volume. Choose between classic view and density view on your bridge system. Wireless monitoring of the trawl opening and intermediate section of the trawl has become a necessity in many of the world’s fisheries.

Mounted in the belly

Mounted in the belly, it shows whether the trawl height is stable or if a bucket effect is arising and allowing fish to escape. It also shows the volume of fish passing through.

Together with a TrawlEye in the opening, it is easy to see whether the fish seen entering the opening end up in the cod end.

Trawl geometry

The TrawlSounder is ideal together with the Door Sensors and the TrawlSpeed/Symmetry sensor to get full control of the trawl’s geometry.
