Sensors

850-165186 / Rev.B
Tuna purse: The sensor must not be
attached to the footrope wire, but to
the foot-rope chain. Use a safety wire
in addition in case the sensor is ripped
off the net.
Trawl or Danish seine: The sensor is
normally attached to the headrope.
For secure fastening and stable
positioning of the sensor pointing
towards the vessel, make a fine mesh
bag sized to the middle of the
head-rope. Size two snap hooks
approximately 10 - 15 cm from the
headrope forming a bridle, and keep
the sensor stretched by means of two
rubber straps attached to the aft
fastening lugs.
