100% Fluorocarbon Line
This line is made by combining a carbon base (polyvinylidene fluoride) and other materials to form a line that is almost invisible underwater since its refractive index is the same as water. Therefore it is very useful in clear water. Light goes through fluorocarbon fishing line the same way it goes through water since the refractive index is the same for both. Fish are often line shy, especially in clear water,and invisible line helps overcome this problem. In clear water you are more likely to get bites if you are using fluorocarbon line. You can even get fluorocarbon swivels that are invisible.Invisibility Knot Strength - Fluorocarbon disappears under water but is hard to see above the water, It’s strength is stronger than nylon line, and it is less likely to be destroyed by big fish with sharp teeth.
