  • Page 81 9. We recommend to use a protective cage made of metal bars around pockets to protect sensors, like the examples below. Note: Make sure there is sufficient space between the protective cage and the sensor pocket, so that if the cage becomes bent, you can still remove the sensor. Installing Door Spread Sensors You need to install Spread sensors in pockets welded to the trawl doors.
  • Page 82 1. Remove the screw holding the pocket cover. 2. Install the Master sensor (red marker) on the port door and the Starboard sensor (green marker) on the starboard door. 3. The top of the transducer (side with marker on housing) must be oriented toward the vessel and the side of the transducer with the circle or A letter must be oriented toward the opposite door.
  • Page 83 1. Remove the screw holding the pocket cover. 2. Install Door Sounder sensors inside each door pocket: the top of the transducer (side with marker on housing) must be oriented toward the vessel and the side with the circle/ A must points downwards with an angle of 25° in relation to the door. Note: For bottom trawling, install sensors on the lower part of doors.
