Figure 39 PI Twin Spread application
The purpose of the Simrad PI Twin Spread sensor system is to measure the distances
between the two trawl openings on a dual bottom or pelagic trawl. A PI Spread sensor
is mounted on the port door, while two PI Remote sensors are placed on the centre
clump and on the starboard door.
The three sensors communicate using special transverse acoustic links. Using these links
the PI Spread sensor measures the exact distance between the three sensors.
