SS4 Door Sensor
An important factor in all kinds of trawling is having control of your trawl doors. Water flow, speed, depth, wire length, bottom conditions and under water currents will affect the performance of your doors and the trawl efficiency
Functions in the new SS4 DS
DISTANCE: Door distance, bottom & pelagic trawl
DEPTH: Door depth
TEMPERATURE: Sea water temperature
TENSION: Tension in trawl wires or sweeps
ANGLE: Door angle (roll & pitch)
STABILITY: Door stability (ScanFactor)
The sensors can be bought with one or several functions, and can be upgraded later via license.
The new design with double casting of the electronics provides 100% protection. Scanmar’s newly developed super plastic drastically reduces damage to the sensor due to strokes, tension, or if doors get hooked on the bottom.
Batteries & 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.
