SCANTROL of Bergen, Norway. says its new autotrawl system uses 'intelligent symmetry control' to increase the catching efficiency of the trawl while retaining the user-friendliness of its previous system.

The company's new generation of symmetry control autotrawl systems came about after two years of research and development in close contact with users.

Scantrol says its system is intelligent. using information from different sources ö such as the speed of water flow in the trawl ö to improve the catching efficiency of the trawl.

Operating on a Windows compatible platform, a new computer and monitor is designed to give a simple presentation for monitoring and controlling the trawl geometry and catching efficiency.

Skippers will have in the trawl panel display information about the symmetry of the trawl. the wire lengths and the history of different parameters.

The new history function is a graphic presentation which shows how the trawl haul develops and gives an opportunity to go back to the parameter status at any particular moment.

This way it is easy to go back to get an overview and understanding of what really happened and compare different trawl hauls.

A new and important function allows the skipper to choose the sensitivity of the winches as he wishes. In different weather conditions and fishing situations, the skipper may want the winches to be more active or slower, or even tow with the brakes on and this model allows him to easily do this.

Scantrol is also introducing an automatic mode that adjusts the sensitivity depending on the vessel movements.

This latest model has a new operating keyboard giving the users optional choices and more user friendly solutions. It is delivered with touch screen or normal LCD monitor of choice.

The system will be on board the first fishing boats this month and will be ready for deliveries in February and March.

Scantrol offers upgrades to fishing vessels already using Scantrol 2000 and it is set up to easily upgrade all other types of auto trawl system.
