Scientific Anglers Amplitude Series Fly Lines

 

When we see room for improvement, we jump at the chance. In this case, we wanted to make our lines even slicker and more durable. Which brings us to AMPLITUDE. The first series of lines to feature the revolutionary AST PLUS slickness additive, the Amplitude will shoot farther and last longer than any other line on the market. It’s SLICKNESS down to a SCIENCE.

 

Amplitude Infinity

Amplitude Infinity

The go-to line for all freshwater species

The first series of lines to feature the revolutionary AST PLUS slickness additive, the Amplitude series will shoot farther and last longer than any other line on the market. It’s slickness down to a science.

The conventional wisdom in fly fishing is that there’s no such thing as a “do it all” freshwater line. We have something to say about that. The Amplitude Infinity has the power to bomb out streamers, yet retains delicacy for dry flies. It mends like an absolute dream, and delivers flies at all distances. Built a half-size heavy, with a long head and substantial front taper, it’s perfect for everything from trout to bass. There’s a reason we call it the Infinity: there is no end to what you’ll be able to do with it.

  • Features the revolutionary AST Plus slickness additive for superior shooting ability and increased durability
  • Floating Texture on the tip section for the ultimate in floatation; it simply keeps dry flies floating longer
  • Shooting Texture running line delivers longer casts, thanks to a reduction in friction
  • Extremely versatile general-purpose taper designed for most freshwater species; an excellent fly line for trout, grayling, panfish, bass, carp, steelhead, salmon, and pike
  • Made a half-size heavy to load fast-action rods, but works well with a variety of rod actions
  • Extended head length for long-distance casts and superior mending ability
  • SA ID - SA AMP INFINITY WF X F (X = line weight)
