The purpose of the Simrad PI Geometry sensor system
is to monitor the geometry of your trawl or danish seine.
is achieved by making accurate measurements of the distances between
the centre of the headrope (or footrope) and each of the trawl doors
or wing ends. If these distances are not identical the trawl (or danish
seine) will be skewed and unbalanced, and this reduces the catch efficiency.
The PI Geometry sensor system
- One Simrad PI Geometry sensor
- Two Simrad Mini-R responders
The results from the measurements made by the sensor system
are transmitted by acoustic signals to the PI catch monitoring system
mounted on the vessel. Based on the information, you can take immediate
corrective actions if it is necessary to adjust the net.
PI Geometry sensor system has been developed to be used on both bottom
and pelagic trawls, as well as pair trawls and danish seiners.
