Nippon Ghost Fluorocarbon Line First of all, it is a 100% fluorocarbon line with very high drag and friction resistance, along with being Japanese. Physical features: The most distinctive feature of fluorocarbon lines is that they are almost 99% invisible in water. Since the refractive index of fluorocarbon lines is very close to that of water, they become almost invisible in water. Fluorocarbon lines are quite hard lines, and their knot strength and drag values are also lower than monofilament lines of the same thickness. To test fluorocarbon lines: When you hold the end of the line in a fire and burn it, you will see that it does not shrink or curl like nylon or monofilament lines. The side of the line will darken like coal. This is how you understand whether fluorocarbon lines are real or not. Purpose of use: Used to prevent fish from noticing and frightening prepared fishing gear.
