Once limited to extreme duty as saltwater leader material, fluorocarbon leader has in recent years become a popular option for anglers in many situations. One of fluorocarbon leaders biggest benefits is it's nearly invisible underwater. This is because it doesn't noticeably distort light passing through the line (it has nearly the same refractive index as water), and it's a huge factor in clear water and when targeting skittish fish.
