Installing the Sensor on the Trawl
We recommend to install the sensor on the headrope in order to see the trawl opening and fish entering the trawl.
- Place sensor (1) at the centre of the net's headrope (2), facing the vessel.
- Install a double-mesh piece of netting (3) to stabilize the sensor.
- Buoys (4) on either sides provide a level platform for the unit during trawling operations.
- Buoys ensure that down-looking transducer beam (5) is vertical for footrope (6) detection.
- The signal is oriented toward the vessel (7).
We recommend you to use a netting bag placed on a suitable location in the net. Use a safety line between one of the sensor's attachment lugs, as shown in the picture. The safety line should be a steel wire with fitted small shackles at either end. |
Important: Sensors not properly secured may be lost during
fishing operations.
