The Trawl Unit’s Deployment Pack is the main underwater container for the Simrad FX80 system. It is made from polyurethane and has been designed for tough use in the harshest of environments, yet it is easy to handle.
There are two separate units assembled within the steel frame of the Deployment Pack. The first unit is the DFS75 Sonar Head. The second unit is the Communication Hub. The third-wire cable is connected to this hub, which provides the interfaces to the Camera Unit and the DFS75 Sonar Head.
The mounting kit supplied contains the strain-relief cable gland, the pigtail, and other hardware devices used to attach the
trawl cable to the headrope on the trawl.
