A dedicated sensor has been developed to check if your gear is skewed. The sensor can be used on both bottom and pelagic trawls, as well as on danish seines.
On trawl gear, the PI Geometry sensor system will measure if the trawl is skewed. Used on a danish seine, the sensor will detect variations in the distance from the centre of the headrope (or footrope) to either wing of the seine. It will also detect differences in the rope lengths when the seine is closed.
