The DFS75 trawl sonar is provided as a natural extension to the Simrad FX80 catch monitoring system, which also provides a live video feed.
Together, these two systems offer several key features:
This screen capture (in replay) shows the opening of a bottom trawl. On the middle view you can easily see the trawl opening and the flat bottom. On the left view, the optional built-in optional echo sounder shows the depth variation of the bottom. Both single
fishes and schools are easily detected due to the high operational frequency used by the trawl sonar.
