A real-time video feed from the trawl has long been desired by fishermen and researchers alike. Cabling and slip-rings have been the issue. One of the primary design criteria of the Simrad FX80/DFS75 system was to make it work on existing 3rd wire cables. We have achieved this goal using copper core coax cables. The use of existing copper core coax cables eases the cost and reduces the installation time.
The Simrad DFS75 Trawl sonar is integrated into the Simrad FX80 system to establish an efficient and accurate monitoring system for your gear and your catch. The combination of the high resolution images from the trawl sonar and the live video feed provides you with an unparalleled opportunity to identify and analyse both trawl movements and fish behaviour.
The entire Simrad FX80/DFS75 system - with live video and high resolution sonar - is controlled from a standard Processor Unit provided by Simrad. It is small, but yet powerful, and contains no moving parts. The system design will allows you to use two displays.
Many users prefer this configuration, as it allows them to use one display system for the trawl sonar presentations, and another for the live video feed.
A typical DFS75 display presentation is shown. Two views are provided, an Sounder view on the left hand side (A), and a Vertical view on the right hand side (B). In this example, the Vertical view is set to presentation mode Net opening. This example has been made in Playback mode with previously recorded data. For this reason, certain presentation elements are not shown. The menu options also reflect the chosen operational mode.
