Nearly invisible in water The fluorocarbon leader line is nearly invisible when submerged, enabling you to present bait without spooking fish and increasing your chances of a successful catch. Durable and protective Offers excellent abrasion resistance compared with standard monofilaments and helps shield your main line from damage caused by fish teeth and underwater obstacles. Soft and strong Safer than stainless steel wire in terms of bending and tangling, this leader resists deformation and acts as a shock absorber during sudden pulls, delivering reliable durability in many fishing situations. Fast response and high sensitivity Its sinking ability and heightened sensitivity let you feel even the weakest bites, making every outing more rewarding. Use scenarios - Freshwater finesse fishing: Use with light tackle for bass or trout around submerged structure or vegetation where invisibility helps entice bites without spooking fish. - Saltwater bottom or near-structure fishing: Protects the main line when fishing around reefs, rocks, or rugged underwater terrain and helps resist bite-off from teeth and sharp objects. - Depth control and lure presentation: The sinking leader maintains lure depth in current or when casting into deeper water, while its high sensitivity helps detect subtle takes.
