The trawl is often towed at great distances from the vessel,making cable based net instrumentation too expensive for bottom trawlers.So,in 1969, Simrad introduced a brand new acoustic system called the FL Trawl Link.It was the first wireless based Net Instrumentation system and its lack of cable made it a viable option for the smaller operator.It offered all the functionality of the earlier Trawl Eye system without the expense of a cable.The Trawl Link didn’t kill off cable based systems – they are still around today – but cable free set-ups are less prone to damage,making them the obvious choice for bottom trawlers.Though Simrad had successfully implemented acoustic net instrument technology,there was still a long way to go,and many problems to overcome if the full trawl picture was ever going to be presented to the fisherman without the use of cable.
