Scientific Anglers Amplitude Big Water Taper Fly Line

When it comes to chasing the world’s largest and most powerful fish, you need gear you can trust. The Scientific Anglers Amplitude Big Water Taper (BWT) is the pinnacle of fly line technology, designed to handle the most extreme fishing challenges. Whether you're targeting giant trevally, arapaima, or other bucket-list species, this line is engineered to perform under intense pressure, offering unmatched strength, durability, and casting performance.

Built on a 100-lb monofilament core, this line is virtually unbreakable and capable of handling the hardest-fighting fish in the ocean or freshwater. Extensively tested this line is perfect for targeting trophy species like giant trevally, arapaima, tuna, tarpon, and more.

The Amplitude series redefines performance with its ground breaking AST Plus technology. This coating reduces friction for smoother, longer casts, even with heavy flies. It also makes this line eight times more durable than traditional fly lines, ensuring your line withstands the rigours of saltwater and big fish battles.

The floating texture tip ensures exceptional flotation for easy pick-up and visibility on the water whilst the shooting texture running line improves casting distance and accuracy, enabling you to reach distant targets with ease.

Built one size heavy for maximum power and quick loading which is perfect for making quick shots at moving fish. This also helps when casting large wind-resistant flies in challenging conditions.

On the rear of the line a high-contrast sighter marks the back of the line, helping anglers keep track of line placement and monitor fish on long runs. The Heat-Resistant core stays stiff and responsive in tropical climates without tangling or memory issues.

The Scientific Anglers Amplitude Big Water Taper is available in a range of line sizes for you to choose from in our drop down menu and comes in a black/surf/sand colouration.
