Scientific Anglers Amplitude Smooth Infinity

The Scientific Anglers Amplitude Smooth Infinity is a half-size heavy freshwater floating line that does one thing particularly well — it works everywhere. Rivers, stillwaters, mixed fly sizes, long leaders, fast rods or moderate ones — the Infinity's extended head and balanced taper handle the lot without asking you to compromise. If you fish a variety of freshwater situations and want one line that keeps up, this is it.

Technologies

• AST+ – Advanced slickness coating that reduces friction, improves shootability and maintains slick performance far longer.
• 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 – Specialised tip coating that increases flotation for better line control and cleaner drifts.
• SA-ID – Printed line identification system showing taper weight and density for quick recognition.
• 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.
