Simrad has developed two new dual wireless sensors for its PI catch monitoring systems.
According to the company, by combining data that was previously provided by two separate sensors, the new Spread/Depth and Remote/Depth sensors can reduce costs, save fuel, improve catch and enable more information to be provided by the Simrad PI systems.
"The introduction of these new dual sensors means we now offer 11 different sensors for our PI catch monitoring systems, which expands the amount of data available to skippers and reduces the number of sensors needed to provide it. By combining the data of the new sensors with our existing sensors, it is possible to build up a clear picture of what is happening below the surface, which of course helps to improve catch quality and quantity," comments Mads Dahl, Sales Director, Simrad.
The PI Spread/Depth and Remote/Depth sensors are intended for pelagic and bottom trawls, however, they will also prove beneficial for Danish seining. Together they measure the physical distance between the trawl doors and the depth of each door. With this information, skippers will know when the trawl hits the bottom or accidentally surfaces and be able to accurately line the gear up with the fish. It also enables the balancing of trawl doors in relation to sea currents and good trawl geometry, which helps to avoid an inclined trawl opening.
