    In addition, the sensor can measure the temperature, depth, pitch and roll. The Trawl Navigator is available in three sizes: XXL with 4 batteries for a longer battery life, XL with 2 batteries and Stubby with 1 battery.
  • Page 7 The image below shows the display of data received from a Trawl Navigator installed on the headline. Pollocks can be identified close to the bottom. In this second example, the sensor automatic range mode is activated. The range of the sounding is automatically reduced when the sensor gets closer to the bottom, in order to have better quality images.
