Scientific Anglers Amplitude Smooth Infinity Warm
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.
Temperature Rating
- Moderate – 10°C to 25°C
Target Species
- Trout
- Bass
- Carp
