Description
Scientific Anglers Amplitude Smooth Trout Standard is a true-to-weight freshwater floating line. Its mid-length head provides balanced turnover for dries and light nymphs. Suitable for cold and moderate climates it performs well on rivers and stillwaters where accuracy matters.
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 – The improved variant for increased flotation and cleaner drifts.
- SA-ID – Printed line identification system showing taper weight and density for quick recognition.
- Braided Multifilament Core – Supple cold-water core that improves flotation reduces memory and provides smooth stable casting.

Amplitude Smooth Line Features
Scientific Anglers took their revolutionary AST Plus slickness additive and put it into the Amplitude Smooth Series. These lines are smooth like traditional lines, but have increased durability and slickness due to the AST Plus, which is mixed directly into the coatings.
Each line is built with three colours to identify the separate parts of the line, and welded loops for quick and easy rigging.
