Convert your standard floating fly line into an efficient subsurface rigging system with Angler's Image Instant Sink Tips. This removable 4-foot sinking section attaches directly between your fly line and leader butt via quick loop-to-loop connections, eliminating the practical need to pack and swap heavy, expensive spare reels or bulky extra spools. Engineered for 4-weight through 8-weight setups, the Class III configuration sinks at approximately 3.5 inches per second, providing optimal control for driving nymphs, streamers, and woolly buggers deep into bottom-feeding lanes during high-water conditions or fast river flows.
