Why Choose DynIce Data?
DynIce Data is designed to ensure optimal signal transmission from the trawl’s headline to the bridge while providing several operational benefits that enhance reliability and reduce maintenance costs.
- Superior Signal Strength and Precision
With a coaxial copper conductor protected by DynIce Dux Dyneema® special rope, the cable ensures minimal signal loss and sharp sonar imaging. This allows for better control of trawl positioning and improved efficiency in fishing operations.
- Increased Trawl Opening and Enhanced Catch Efficiency
Unlike heavy steel cables, DynIce Data has a low weight and provides buoyancy during towing, lifting the headline and increasing the vertical opening of the trawl. Tests have shown that trawlers using DynIce Data have achieved up to 10 meters of additional vertical opening, significantly expanding the fishing area.
- Lightweight and Reduced Equipment Strain
DynIce Data weighs significantly less than steel cables. A 2,000-meter steel cable weighs 880 kg in air and 676 kg in seawater, whereas the equivalent DynIce Data cable weighs only 326 kg in air and 76 kg in seawater. This reduces strain on winches and other components, extending the lifespan of onboard equipment.
- Maintenance-Free and Long-Lasting
Unlike steel, DynIce Data does not corrode and requires no lubrication. The cable has a proven lifespan of over five years, whereas steel cables often need replacement within one to two years.
- Proven Performance on Leading Trawlers
DynIce Data has been tested and successfully implemented on multiple large vessels. The Faroese trawler Tróndur í Gøta operates with a 2,700-meter installation, and skipper Frits Thomsen confirms that the image on the sonar screen is sharp, with excellent signal quality. On the pelagic trawler Beitir, the cable increased the vertical opening of the trawl by 10 meters, providing an additional 2,000 square meters of fishing area.
