Scientific Anglers Amplitude Smooth Infinity Plus Freshwater Floating Fly Line, Fishing Line, Smooth Casting, Durable Coating

Scientific Anglers Amplitude Smooth Infinity Plus Fishing Line is built for anglers who want effortless distance, clean loops, and confident presentations across changing conditions, combining decades of fly-line innovation with a refined, ultra-slick smooth coating that shoots through guides with minimal drag for long casts and quick line pickup. Designed as a versatile Freshwater Floating Fly line that also transitions seamlessly into saltwater sessions, it delivers stable flotation and consistent handling whether you’re working dries, nymph rigs, streamers, or indicators, with a taper engineered to load modern rods efficiently and maintain control at both short range and at distance. The “Infinity Plus” profile adds extra power when you need to turn over larger flies or manage wind, while the durable polymer construction resists wear and keeps performance steady over time, helping you spend less effort on maintenance and more time dialing in accuracy, mending, and drift. Offered in various weights to match your rod and target species, this line is a dependable choice for anglers who want smooth, repeatable casting performance from the first false cast to the last light of the day.
