Description

Details

Doorspread is the distance between the doors on a single trawl. On a twin rig and double rig, the spread on EACH net is given.

On triple and quad gear, three and four doorpsreads are monitored. • Major fuel savings are achieved with doorspread as you can adjust 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.

  • Indicates when your doors have crossed
  • Detects when your door has fallen or is stuck • Instantly see if you have a rock, pot or other debris in the trawl.
  • Notus has the only omnidirectional sensors on the market. You will still see doorspread on a turn with one door 100 meters behind the other. Depth sensors indicate the distance from the surface to the doors/trawl. • When mid watering, trawl depth allows you to place 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 indicates if you shoot too much trawl wire as the door heels over. • Indicates when the doors are on bottom. Temperature sensors indicate the temperature wherever the sensor is located.
  • Locate larger schools by trawling in the right temperature range.
  • Determine if you are in the right temperature for the species you are targeting • Determine where the fish are
