Simrad PX70
Smart trawl control system
Deep insight into gear performance and catch
The Simrad PX70 builds on the PX15's capabilities, adding a suite of advanced sensors that provide a comprehensive view not only of gear behaviour but also of what is happening inside the net. Key additional features include flow speed measurement within the net, a critical parameter for assessing the gear's hydrodynamic efficiency and its impact on catch performance.
The Simrad PX70 system also integrates real-time biomass information and catch estimation, enabling precise decisions about the optimal moment to haul back, reducing unnecessary towing time and maximising the return from each operation. The PX70 is designed for purse seiners and trawlers operating in demanding fishing grounds where detailed knowledge of gear behaviour and resource abundance directly determines each trip's profitability.
Every net has a limit. Now you can see it.
Beyond a certain speed, your trawl stops filtering efficiently. Water builds up and creates turbulence; the flow becomes unstable, and performance drops. Until now, this limit has been invisible. When you combine your gear monitoring system with the Simrad PX Flow sensor, you can measure the real water flow into the net in real time. You can then identify the optimal towing speed and avoid costly inefficiencies. The result is less guesswork, more control and better catches.
Better geometry, higher efficiency, and a more consistent catch
Maximising performance goes beyond towing power; it requires precise control of the net geometry. Maintaining the correct wing-end angle, aligned with the net’s rigging coefficient, is key to maximising flow efficiency, reducing drag, and delivering consistent, high-performance trawling. When geometry and rigging
are perfectly balanced, water flow remains smooth and evenly distributed, enhancing filtration and overall gear stability.
