TRAWLMASTER 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.

Activ-Omni Intelligence The Notus Difference 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...

Trawlmaster is a wireless trawl monitoring system that provides complete trawl geometry. Over 6000 sensors delivered Trawlers world over have experienced significant fuel savings coupled with increased catches. Knowing the trawl’s geometry allows the user to keep the trawl optimal during every tow. Trawl wire lengths provide you with confidence that the trawl doors are in line. In cross currents, an adjustment is provided to align the doors. Door spread sensors allow users to tow by spread, not by speed. This is a well proven method to increase catches in heavy current. Upgrades can be...

DOORSPREAD AND TRAWL WIRE LENGTHS Doorspread is the distance between the doors. 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. The Notus Trawlmaster Doorspread sensor: For twin and multi-rigging vessels, the spread on EACH net is provided. This allows for equal bulk in EACH net. • Indicates when doors have crossed • Detects when door has fallen or is stuck • Instantly sees if a rock, pot or other debris is in the trawl • Is the...

MIDDLE WIRE ADJUSTMENT The Middle Wire Adjustment is calculated to align the middle weight (clump) with the doors on twin rigs Issues with a misaligned clump: • When the clump is ahead of the doors, the trawl overspread, and the footgear comes off bottom • When the clump is behind the doors, the trawls under-spread, which leads to gear damage The Notus Trawlmaster Middle Wire Adjustment indicates the exact middle wire adjustment to align the clump with the doors, to ensure optimal fishing!

Doorspread and Trawl Wire Lengths are standard Trawlmaster sensors. These sensors can be upgraded to include Door Depth, Door Angle and Temperature. Depth sensors indicate the distance from the surface to the doors/trawl. • When mid watering, trawl depth allows for placement of the trawl at depth of the fish • When bottom trawling, depth will indicate when the gear is on bottom Door Angle sensors provide the heel angle (inward/outward lean) and pitch angle (upward/ downward pitch). • Set the trawl doors for optimal spread and optimal fuel consumption • Instantly indicate if too much trawl...

HEADLINE HEIGHT SENSOR Headline Height sensors use an echo sounder to measure the distance from the headline to the seafloor. An optional footgear clearance sensor can be added to monitor the net opening and footgear clearance. • Raise and lower headline depending on species and trawling conditions • Indicate if the trawl is raising off the bottom due to towing too fast For videos, brochures and more, please go to www.notus.c

CATCH SENSOR Catch sensors indicate when the cod-end has a set amount of fish. Multiple sensors can be used to indicate different amounts of fish. Notus Trawlmaster Catch sensors: • Confirms that the trawl is fishing • Only take back what you can handle onboard • Prevents hauling back a trawl that is only half full • Provides a better indication of exactly where the fish are in the tow • Has a built-in gear location feature should you lose the trawl or just the cod-end • Improves fish quality • Prevents gear damage associated with over-filling the net For videos, brochures and more, please...
