Low Visibility—One of fluorocarbon's biggest benefits is it's nearly invisible underwater. This is because it doesn't appreciably 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.

Abrasion Resistance—Fluorocarbon's low visibility characteristics allow anglers to use stouter pound test lines in situations such as heavy cover tactics for bass. As an added benefit it also has incredible abrasion resistance and as such has quickly become a top choice of the pros when fishing the thickest cover or dragging baits along the bottom.

Sensitivity—Fluoro's tightly packed molecules transmit more energy than mono, better telegraphing information from the other end of the line, such as light bites or your lure ticking bottom. Also boosting sensitivity, fluoro sinks faster than mono, resulting in less slack or bow between the lure and rodtip.

Toughness—Fluorocarbon is more abrasion resistant than standard nylon monofilament of the same diameter. Plus, while the sun's harsh ultraviolet rays weaken nylon over time, fluorocarbon shrugs off UV with no ill-effects.

Waterproof—Unlike mono, fluoro doesn't absorb water. This means it has the same strength, sensitivity and handling below the surface as it does when dry. It feels and acts the same on your first cast as it does on your last.

Hooking Power—Lacking the low-end stretch of nylon mono, fluorocarbon delivers more solid hooksets, even at long distances. If you need to drive the hook home at the end of a long cast, this is a key consideration.
