BAMfluoro™ How It Works

Why is a fluorocarbon leader less visible to fish? It has to do with a material property called "refractive index".  The refractive index of a material dictates how it interacts with light, and the difference in refractive index between two materials impacts how much light is reflected as light passes from one material into another.  For example, the difference in refractive index between air and water causes the glare seen while fishing.  The larger the difference in refractive index between two materials the more light that gets reflected, making the material appear brighter and more visible.  Since the refractive index of the fluorocarbon leader is close to the refractive index of saltwater, very little light is reflected by the leader as light passes through water making the leader difficult for the fish to see. This is why a fluorocarbon leader catches more leader shy fish than nylon monofilament.
