Prevent bite-offs while fly fishing with the Scientific Anglers Predator Leader. This prefabricated 2-part leader combines a 7.5 length of abrasion-resistant leader material with a 15 section of 1x7 stainless steel wire to reduce the chance of losing both fish and fly. The wire is coated in black nylon for maximum stealth, and the leaders precision taper helps in turning over large flies with smooth efficiency.
