200 yard spool of 12 lb. Fluorocarbon. Line Diameter/Inches/ Millimeters: 12lb./.012/.30 This is the ultimate Fluorocarbon fishing line. Super sensitive so you can feel the bottom, with very little stretch for superior hook setting power. Hi-Seas 100% Fluorocarbon Line is extruded under strict quality control standards using the highest quality pure polyvinylidene fluoride. This results in a fluorocarbon that matches the refractive index of water—making it nearly invisible—yet is extremely supple and easy to fish. Hi-Seas 100% Fluorocarbon is abrasion resistant and sinks faster than monofilament, so it won’t affect the natural fall of a bait. Line Diameter/Inches/ Millimeters: 8lb./.010/.25, 10lb./.012/.28, 12lb./.012/.30, 15lb./.014/.35, 20lb./.016/.40
