SCANMAR Flow sensors
Through use of the new Scanmar sensors for observation on fishing and research vessels it has been determined that wind, currents, towing direction and towing speed have crucial meaning for the trawl’s ability to catch.
It has been 25 years since Scanmar launched the combined Trawl Speed/Symmetry sensor. It was obvious that the fishermen were not familiar enough with knowledge of underwater currents and the effect these had for efficient fishing. They towed according to the GPS-speed, and trusted the winch producers’ statements that the trawl was correctly towed as long as the warps were equal, and with the same pressure on the winches.
The new family Flow sensors consist of combined TrawlSpeed/Symmetry sensor, pure Symmetry sensor and Tunnelflow sensor, and a half-brother; the Grid sensor.
