SS4 DoorSensor
An important factor in all kinds of trawling is having control of your trawl doors. Water flow, speed, depth, wire length, bottom conditions and underwater currents all affect the performance of your doors and the trawl efficiency.
Functions in the new SS4 DS
- Distance
- Door distance, bottom and pelagic trawl
- Depth
- Door depth
- Temperature
- Sea water temperature
- Tension
- Tension in trawl wires or sweeps
- Angle
- Door angle (roll and pitch)
- Stability
- Door stability (ScanFactor)
The sensors can be bought with one or several functions, and can be upgraded later via license.
Construction
The new design with double casting of the electronics provides 100% protection. Scanmar’s newly developed super plastic drastically reduces damage to the sensor from strokes, tension, or if the doors get hooked on the bottom.
Batteries and charging
With new long lasting lithium-ion batteries, charging is in many cases no longer an issue. Many are able to keep the sensor on the door for the whole trip, and only charge when back from the fishing ground.
