Sensors
Clump Sensor
Type SS4-C-VTLA 144
Accurate distance between the clump and both doors on twin and triple trawls.
- Accurate distance between clump(s) and both doors on twin and triple trawls
- Multifunctional: distance, angle, depth, temperature, tension and bottom contact
- Robust construction and plastic protect against damage and wear
- Up to 700 hours of operation time on the clump
- Quick charging
Extended distance measures
To avoid asymmetry when fishing with twin or triple trawls, it is important that the doors and the clump are in line. Information about the position of the doors and the clump in relation to each other is therefore essential.
Construction
The double casting of the electronics provides 100% protection. Scanmar’s newly developed super plastic drastically reduces damage to the sensor.
Batteries and charging
With new long lasting lithium-ion batteries, charging is in many cases no longer an issue.
