The P-Line Halo Fluorocarbon Line - Bulk Spools are the future of fluorocarbon fishing line. Halo's Co-Fluoride design, which blends various pure fluorocarbon crystals, gives the angler the best combination of strength, sensitivity, cast-ability and invisibility under the water. Halo also has a higher specific gravity, giving the line a much faster sink rate.
The P-Line Halo Fluorocarbon Line - Bulk Spools are 100% pure fluorocarbon, so it has a low refractive index making it nearly invisible underwater. This line has been optimized with a mist green tint for use in lakes, rivers, streams and inshore saltwater environments.
