Scientific Anglers Amplitude Fly Lines

The idea behind the Frequency series is a simple one: three floating tapers, three sinking tapers, and limitless fishing options. We kept the choices easy and the prices reasonable. The only question that remains is this: what's YOUR Frequency?

 

Frequency Trout

Here’s an idea: instead of spending $100 on a trout line, pick up a Frequency Trout fly line and use the rest on your next drive-all-night road trip. The Trout taper features a versatile, mid-length head ideal for delicate dries; however, it also provides great line control for nymph rigs. If you’re a trout angler, this is your Frequency.

Features:

  • For use in cold to moderate climates
  • All-around trout fly line
  • Versatile taper excels with most flies and conditions
  • Excels in all weather conditions
  • Mid-length head
  • Formulated with Advanced Shooting Technology
  • Braided multifilament core

Frequency Double Taper

Here’s an idea: instead of spending $100 on a trout line, pick up a Frequency Double Taper fly line and use the rest on your next drive-all-night road trip. The Double Taper features subtle front and rear tapers ideal for delicate dries and makes mending at any distance a breeze. If you’re a trout angler, this is your Frequency.

Features:

  • For use in cold to moderate climates
  • All-around trout fly line
  • Versatile taper excels with most flies and conditions
  • Excels in all weather conditions
  • Formulated with Advanced Shooting Technology
  • Braided multifilament core

Frequency Boost

Let’s be honest. No one will ever turn down a little extra help with their cast. Luckily, the Frequency Boost, built a half-size heavy, provides just that. This general purpose floating fly line loads quickly, turns over large dries, nymph rigs, and streamers with ease, and features a mid-length head perfect for nearly all freshwater applications.

Features:

  • For use in cold to moderate climates
  • Excellent general-purpose line
  • Half-size heavy and more powerful than the Trout taper
  • Better with larger, heavier flies
  • Supple and easy to use
  • Versatile mid-length head
  • Braided multifilament core

Frequency Magnum

The Frequency Magnum summed up in six words: big flies, big fish, small price. Designed with an aggressive weight-forward head, the Magnum fly line is built for tossing large flies, turning over split shot, and blasting through the wind. In other words, this line is a bit of a bully - which is great if you’re targeting bass, big trout, and light saltwater game. It’s nice to have some muscle on your side.

Features:

  • For use in cold to moderate climates
  • Turns over large dries, streamers, and split shot with ease
  • For use in both fresh- and saltwater environments
  • Overweighted design loads fast-action rods
  • Braided multifilament core

The Frequency Magnum summed up in six words: big flies, big fish, small price. Designed with an aggressive weight-forward head, the Magnum fly line is built for tossing large flies, turning over split shot, and blasting through the wind. In other words, this line is a bit of a bully - which is great if you’re targeting bass, big trout, and light saltwater game. It’s nice to have some muscle on your side.

Features:

  • For use in cold to moderate climates
  • Special nighttime-glow colouration for visibility
  • Turns over large dries, streamers, and split shot with ease
  • For use in both fresh- and saltwater environments
  • Overweighted design loads fast-action rods
  • Braided multifilament core

Frequency Sink Tip

In moving water, getting flies below the surface while maintaining control can present a challenge. That’s why sink tip fly lines were introduced. We took this idea, put it at an affordable price point, and came up with the Frequency Sink Tip. Featuring a Type III 10′ sinking tip, the Frequency Sink Tip is great for streamer fishing from a boat, while wading, or just about anywhere—mall water fountains excluded.

Features:

  • For use in cold to moderate climates
  • Ideal for streamers and wet flies for trout, bass and bream in moving water
  • Fast-sinking 10’ tip sinks flies through the water column
  • Mid-length head enhances control
  • Best used in moving water
  • Sink rate: 2.5–4 inches per second
  • Braided multifilament core

Frequency Intermediate

There are times where you need to get your fly underwater, but not too far under the surface. That’s when you need the Frequency Intermediate fly line. Built with a slow sink rate, the Frequency Intermediate will pull streamers and wet flies under surface chop to get them where the fish are. Perfect for stillwater situations, and good for chucking streamers in rivers as well, at this price, it would be silly not to get one.

Features:

  • For use in cold to moderate climates
  • Especially effective for fishing streamers
  • Thin diameter cuts through wind
  • Ideal for use in stillwater situations
  • Mid-length head for enhanced line control
  • Sink rate: 1.25 inches per second
  • Braided multifilament core

Frequency Full Sink

If there’s a better way to fish lakes and ponds than with a full-sinking line, we haven’t found it. The Frequency Full Sink is the perfect sinking fly line for stillwater anglers; it handles streamers and wet flies with aplomb, cuts through the wind, and features a mid-length head for great line control. We built the Frequency Full Sink with two sink rates and the idea that great subsurface lines don’t have to cost a fortune.

Features:

  • For use in cold to moderate climates
  • Especially effective for fishing streamers
  • Thin diameter cuts through wind
  • Ideal for use in stillwater situations
  • Front welded loop on Sink 3; Sink 6 includes braided loop connection
  • Mid-length head for enhanced line control
  • Sink rates available:
    • Sink 3: 2.5–4 inches per second
    • Sink 6: 5–6 inches per second
  • Braided multifilament core

Frequency Saltwater

Here’s the deal: it’s still possible to get a heckuva fly line for less than 50 bucks. The Frequency Saltwater is a great all-around compound saltwater taper designed to load rods quickly and cut through the wind. What’s your frequency?

Features:

  • For use in cold to moderate climates
  • Overweighted to assist in punching through the wind and turning over large flies
  • Floating compound taper ideal for fish both on and off the flats
  • Built for use in a wide variety of weather conditions
  • Mid-length head
  • Braided multifilament core
