Would you shoot your gear without knowing when the trawl was starting to fill?

Catch sensors have become key items of equipment, providing not just information on how fast the codend is filling up, but also giving vital indication on whether or not the gear is skewed, helping you avoid those lost tows.

On top of all that, each catch sensor transmits a precise temperature reading to the wheelhouse. Marport’s catch sensors are among the most sophisticated on the market today, offering advanced single, dual or simultaneous operation to provide a reliable signal and to ensure uninterrupted communication with the gear.

We provide high sensitivity and rapid response times, plus updates at 20 second intervals, along with a typical battery life of between 380 and 540 hours, extendable by enabling low power functions.

Our catch sensors are programmable on board and can be used as direct replacements for 40kHz (Simrad® and Scanmar®) and 70kHz (Simrad® and Wesmar®) sensors.
