Scientific Anglers Amplitude Textured Infinity is a half-size heavy freshwater floating line built for rivers and stillwaters. The long head design supports accurate mending and stable turnover with mixed fly sizes. Textured coating reduce friction for longer casts and improved flotation while maintaining dependable handling in cold and moderate climates.

Technologies

AST+ – Advanced slickness coating that reduces friction improves shootability and maintains slick performance far longer.
Floating Texture – Diamond-shaped embossed pattern that increases flotation and enhances line ride for superior performance.
Shooting Texture – Rounded embossed pattern that reduces friction boosts durability and improves shooting distance.
Welded Loops – Durable welded loops on both the front and back of the line for easy reliable loop-to-loop connections to backing and leaders.
Improved Dry Tip – The improved variant for increased flotation and cleaner drifts.
SA-ID – Printed line identification system showing taper weight and density for quick recognition.
TRP – Textured tactile band on the line that marks key positions for repeatable casting accuracy.
Camo Tips – Multi-colour blended tips that break up line visibility for stealthy presentation in clear water.
Braided Multifilament Core – Supple cold-water core that improves flotation reduces memory and provides smooth stable casting.
