    Get a basic knowledge of the sensor. Introduction Marport's Catch Navigator tells you when your trawl starts to fill. Placed on the top of the trawl codend, it monitors the amount of catch that you have and warns you when the trawl is full.

  • Page 7: Applications

    Applications Examples of data received and displayed in Scala2 application. 1. Catch status: empty / 2. Catch status: full / 3. The echogram shows the codend filling up, until the catch sensor is triggered. Safety Guidelines Important: To ensure proper and safe use of this equipment, carefully read and follow the instructions in this manual.

    You can create a table with a list of frequencies and complete it when you add sensors. Frequencies and intervals The diagrams below show the bandwidth of the different types of Marport sensors and intervals you must respect when adding other sensors. Figure 1. PRP sensors (e.g. Catch sensor, Trawl Speed, Spread sensor...) Example: If the frequency of the sensor is 40kHz, there should be no sensors between 39.9-40kHz and 40-40.1kHz.
  • Page 61 Figure 3. NBTE sensors (e.g. Speed Explorer, Trawl Explorer, Catch Explorer, Catch Navigator, Door Sounder) Example: If the frequency of the sensor is 40kHz, there should be no sensors between 39.8-40kHz and 40-40.6kHz. Figure 4. HDTE narrow band mode Example: If the frequency of the sensor is 40kHz, there should be no sensors between 39.8-40kHz and 40-41kHz.
  • Page 62 • We recommend to allocate frequencies between 34 and 56 kHz for wideband hydrophones and between 41 kHz and 44 kHz for narrowband hydrophones. • Echosounders are usually placed around 38 kHz, make sure to allow enough distance with them. Catch Navigator | V1 | Appendix...
