Learn how to install the sensor on the trawl gear.

Installing the Catch Navigator on the Trawl

Sensors can be installed with the pull cords on the side or on the center of the sensor.
Pull cords are attached to the net. When the net fills up and the meshes expand, cords
are pulled and this triggers the catch sensor.
1. Install the sensor on the top of the codend with the UP side of the housing
oriented toward the vessel. You can install a double-mesh piece of netting to
stabilize the sensor. Make sure there is nothing in front of it that would block its
signal.
Tip: If the meshes of the net obstruct the Catch Navigator signal, you can
install the sensor inside the codend.
2. Securely attach the sensor to the net by its front and back attachment lugs:
a. We recommend to attach the front and back attachment lugs with rope.
This prevents metal to metal contact and extends the life of the housing.
b. When you attach the sensor, stretch the net codend at the point where you
need the catch status to become full.
c. Once installed, make sure that when the net is fully stretched out it does
not cause stress on the attachments points.
