Simrad PI Geometry
Information on the responder identification
label
The Simrad PI Mini-R responder label provides the following
information.

PI Mini-R responder, information on the sensor
identification label
A
Position identification. Red colour identifies the port
responder, while green colour identifies the starboard
responder.
B
This information identifies the sensor type.
C
Order number.
D
Water switch. This is a sacrificial bolt. The bolt will
gradually be worn out. Check it from time to time to remove
corrosion, or replace it if necessary.
E
Transducer for communication with the PI Geometry sensor.
Why use the PI Geometry sensor system
In order to maximize the performance and the catch efficiency,
the trawl and the warps must be adjusted properly. This is
essential to ensure a square trawl and minimum skew. This is
also important for danish seines, as the ropes must have identical
length.
Any disturbance to the trawl movements may have a negative
effect on the catch. This is particularly important on a bottom
trawl. A skewed bottom trawl will result in unstable bottom
contact, and create escape routes for fish below the gear and
through the side panels. On pelagic trawls and danish seines a
