P-Line Halo Fluorocarbon - The future of fluorocarbon fishing line is Co-Fluoride. So P-Line has blended different types of pure fluorocarbon crystals, giving anglers the best combination of strength, sensitivity, and castability in the best all purpose fluorocarbon line available. Because Halo is 100% pure fluorocarbon it has a low refractive index making it invisible underwater. The specific gravity is much higher than traditional fishing lines, giving the line a much faster sink rate. Halo comes in a new translucent low visibility Mist Green color, optimum for lakes, rivers, and inshore saltwater applications.
