The Notus Trawlmaster is a wireless net monitoring system. Its design is based on more than 25 years of experience. Notus has worked closely with customers to offer sensors that provide reliable, real time data and convenience of use. With our unique and reliable Activ-Omni Intelligence, Notus offers the only net monitoring system to boast two-way communication, offering trawl wire lengths, AND true omnidirectional capabilities, providing sensor data when it’s needed most. THE NOTUS TRAWLMASTER PROVIDES OPTIMAL PERFORMANCE, FOR SUPERIOR RESULTS. Notus sensors boast an active, two-way communication system, not offered by other net monitoring systems. Instead of relying on traditional one-way pingers, Notus systems ‘talk’ to each other via proven two-way protocols. Using this reliable technology, Notus is the ONLY system capable of delivering trawl wire lengths with doorpsread of EACH net, giving a true geometric view of the gear. Variable data rates: 5, 10, 20 and 60 second intervals Notus is the only system to offer true, omnidirectional pattern beams in all of our net monitoring sensors. This is critical when turning, when a door has fallen over or when fishing gear is lost. Doorspread is the distance between the doors on EACH net. Major fuel savings are achieved with doorspread by adjusting the speed of the vessel to keep the optimal spread. For example, towing just 0.1 knots too fast into a current can overspread the gear by 10 meters.
