The FS70 trawl sonar is a 3rd wire system which provides the full picture of the trawl opening and position relative to the bottom, allowing the fisherman to have full control of any type of trawl fishery.
The system provides real-time images from the trawl sonar head and the data from the PI sensors to the bridge, this maximizing the quality of the catch and increasing efficiency at sea.
A major benefit to the third wire integration with PI sensors is to prevent loss of communication with the trawl as the vessel is changing course or in heavy sea conditions.
Same as for the SX90 hull sonars, the FS70 trawl sonar has already proven very popular in Bay of Bengal on-board larger vessels where a cable winch can be installed.
