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.
