Duel H4396-SP Invisible to Fish Pink Fluorocarbon Boat Leader 100m No. 2 SP 100% High Molecular Weight Fluorocarbon Easy for humans to see, invisible to fish, increasing catches for all fish species!! Big fish caught! The only "invisible to fish pink fluorocarbon" Born from scientific evidence and extensive fishing tests, pink fluorocarbon achieves "invisibility to fish" through a "color filter effect Patent P." using a special formulation that cuts off the wavelengths fish perceive. Employs "Stealth Pink," which is easy for humans to see and difficult for fish to see. Covers a wider "color range invisible to fish" than general pink lines Patent P. Uses high molecular weight fluorocarbon material, is flexible and tenacious, and features a large spool that is resistant to coiling. Thank you.
