Catch function
Scanmar SS4 CatchSensor meets all the requirements any fisherman could have.
The Catch function is activated by the stretch wire when the trawl is filled to the point where the sensor is mounted, so the skipper can follow the gradual filling. The SuperCatch function has a faster update rate and shows a quicker activation, which is particularly important to avoid overfilling.
Filling indicator (angle)
Indicates the filling rate using both pitch and roll angle measurements on the cod end.
The pitch measurements show how the bag gradually fills up to the point where the sensor is mounted. The roll angle (twist) shows how the bag twists when it begins to fill, and how it gradually corrects itself when it becomes full. The sensor can be programmed for normal or quick updating.
Up/Down function
The Up/Down function notifies the user when the cod end twists and is being towed upside down.
Rip function
With the Rip function, the sensor is mounted in the belly of the trawl and alerts the user if it detects rips or tears in the net, to prevent loss of catch and potentially costly damage.
Construction
The new design with double casting of the electronics provides 100% protection. Scanmar’s newly developed super plastic drastically reduces damage to the sensor from strokes, tension or dragging along the bottom with a twisted trawl.
