This is our early warning system

The Rip Sensor is designed to be fixed to a trawl’s belly or tunnel, where it sends an indication of any damage to the gear that could be letting fish escape.

The Rip Sensor operates on a 40kHz frequency, updates every 20 to 30 seconds, works all the way down to 1800 meters and has a typical battery life of 500 hours.

As well as giving early warning of gear damage and loss of catch, the Rip Sensor also has a host of optional extra features, allowing it to transmit pitch and roll, depth and water temperature data to the wheelhouse.
