Description
Description
Scientific Anglers Amplitude Smooth Infinity Warm is a half-size heavy floating line designed for warmwater conditions. Built with a warmwater-friendly coating on a stable core it handles streamers hoppers and poppers effectively. The extended head supports controlled casts at distance and maintains stability when fishing from boats or banks in warmer conditions.
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.
- 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.

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.
