Scantrol iSYM Autotrawl Systems With Patented 'Symmetry Control' Click here for information on Scantrol iSYM (Adobe PDF). It is a fact that when towing with a conventional autotrawl there are situations where the trawl can be skewed,and the catching efficiency sharply reduced.

US vessels with Scantrol ISYM system:
After two years of research, the iSYM replacing Scantrol 2000 was introduced in January 2004. The iSYM is more intelligent adding several new functions to increase catching efficiency of the trawl without comprimising the user friendliness that has become a trademark for the Scantrol systems. This revolutionary new system controls the trawl automatically to get the water flow directly into the trawl opening. A Scanmar symmetry sensor mounted on the headline measures the direction of the water flow in the trawl opening. This sensor is connected to the Scantrol system that controls the tension in the trawl wires individually to get the flow of water direct into the trawl opening. The trawl is filled with water hitting square on, staying open and well spread. Scantrol ISYM display
Correct symmetry is essential for the stability of the trawl, and secures good bottom contact, even when towing along sloped edges. The symmetry sensor is mounted on the middle of the headline, and accurately measures distortions in the trawl geometry. A one meter change in wire length difference is detected by the sensor. SCANTROL improves the efficiency of your trawl in difficult fishing conditions:
