Installing the Seine Sensor on a Purse Seine

Procedure

  1. Attach two separate chains on the 2 front attachment lugs of the sensor using snap hooks.
  2. Attach the chains to the lead line with one snap hook. The yellow transducer must points toward the surface when purse seining and the bottom of the sensor must hang freely to be always aligned with the seabed.
  3. Attach a safety wire from one back attachment lug to a pursing ring (not on the lead line).

    1. Outside of purse seine

    2. Inside of purse seine

    3. Signal toward the vessel (uplink)

    4. Side sounding

    5. Down sounding
  4. Ideally, you can place three sensors at different locations on the lead line of the purse seine: one on a quarter of the length, one in the middle and one on three-quarters of the length. If you have a Seine Explorer, we recommend to install it on the middle of the length. See picture below.
  5. If the net stays on the deck for a long time after hauling, dry the end cap of the sensor to make sure it does not continue to operate.
