Advanced Echo Sounder

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

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

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.
