Catch efficiency and catch quality are important. Using the wide range of sensors available, the Simrad PI Catch Monitoring systems for purse seine and trawl nets provide information about the net's depth, water temperature, bottom contact, net damage and catch volume - just to name a few.
The Simrad PI50 also provides advanced real-time catch monitoring system for trawl and purse seine equipment.
To know how your gear behaves is vital for efficient fishing. The Simrad PI50 system gives you all the details.
The Simrad PI50 Catch Monitoring System provides you with essential information, such as the stability of the trawl doors, the amount and quality of your catch, the behaviour of your bottom or pelagic trawl, or the correct timing of a purse seine.
A large selection of wireless sensors is available for the Simrad PI50. Placed on the trawl or purse seine they will provide you with valuable and accurate information about the gear.
The signals from the sensors are transmitted acoustically through the water, and picked up by a hull mounted hydrophone, or from an over the side towed hydrophone. How often the sensor reports its data is a predefined setting, but if required, it can easily be changed. The Simrad PI sensors are further designed with different transmission frequencies and codes to avoid interference between vessels operating close together. Whenever necessary, these settings can also be modified so suit your requirements.
The small size, quick update rate, long battery life and its long-rangecapability, allows the Simrad PI Catch Monitoring systems to be installed on any size net, from a small sardine net to a large tuna net. The Simrad PI Family interfaces to the latest professional Simrad echo sounders and sonars.
The Simrad PI system gives a new dimension to trawling where new and more robust sensor design, combined with fast update will achieve more efficient trawling. The new PI Spread and PI Remote sensors gives important information about the doors. The PI Spread sensors will detect if the doors are unstable, and if the trawl is incorrectly rigged. The PI Catch sensor allows you to monitor the filling of fish in the cod end, and will thus secure best quality of the catch. The PI Bottom Contact sensor is important for bottom trawling. An alarm will go off if the trawl lifts from the bottom and fish escape under the trawl. For a pelagic trawl the Bottom Contact sensor will give an alarm when the trawl gets too close to the bottom.
The Simrad PI system receives information from multiple sensors at the same time. The net's depth, water temperature and the important bottom contact information are displayed in large digits or in easy to understand graphics on the compact display.
