P-Line Halo Fluorocarbon Line Mist Green 200Yd 20lb The union of unmatched proprietary extrusion technology, coupled with the finest raw materials available, has produced P-Line HALO Fluorocarbon; the first Co-Fluoride introduced into the United States. In a tireless effort of research and development, P-Line has engineered the next generation of fluorocarbon fishing line by introducing HALO Co-Fluoride. Different fluorocarbon crystals have different characteristics. With HALO, 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.
