Height/depth Sensor

trawl-sounderScanmar’s new Height/Depth sensor for Purse Seine provides important and reliable information about the position and the movement of the seine at all times, increasing the catch ability and reducing the danger of tearing up the seine.

The new sensor is developed specially for purse seiners and is a stronger and more robust version of the classic combination sensor for purse-seiners. The electronics is moulded into the same resilient plastics as in the SS4 generation of sensors. This protects against damage. In addition, the sensor body is reinforced with Kevlar-reinforcements. The sensor withstands a strech of 6 tons and is Scanmar’s strongest sensor ever! Includes the specially designed mounting kit with great rupture strenght.

Areas of use

Purse Seine: one or several sensors on the line

USER ADVANTAGE

  • The Depth measurement shows distance to the surface and is used to monitor the sinking speed and the position of the seine in water.
  • The Height measurement shows distance to the bottom and helps the skipper to place the seine closer to the bottom.
  • Start to haul at the right time in the launch phase.
  • Increased catch ability and reduced danger of tearing up the seine.
