Introducing the New 801 Series Trawl Sensors

After three years of dedicated development, Notus is proud to launch the new 801 Series Sensors—a complete redesign of our proven 701 Series.

The switch from NiMH to lithium battery technology delivers three times the battery life of our previous model. That means true full-trip capability for most vessels, while eliminating wasted time changing batteries at sea.

The 801 Series eliminates the need for an extra sensor in the port door or clump. Now, all you need is one sensor in the starboard door and one in the port door. These two sensors still provide full data—door spread, trawl wire length, door angle, and door depth/height—with no compromise on accuracy.

With fewer door housings and sensors, crews spend less time on setup and maintenance, while owners save on installation and equipment costs.

The 801 Series represents a leap forward in performance, efficiency, and reliability—engineered with your feedback, built for your fishery.
