Description
Description
Scientific Anglers Amplitude Smooth Infinity Salt is a half-size heavy saltwater floating line built for fishing tropical flats and coastal shallows. Its longer head carries line efficiently for accurate distance casting and solid mending while maintaining control in wind. Designed for streamers and surface flies it suits boat and wade anglers targeting powerful inshore species.
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.
- Saltwater ID – Same as SA-ID but for saltwater lines.
- Tropi-Core – Extra-rigid tropical monofilament core designed to resist heat maintain stiffness and deliver powerful turnover in hot climates.
Temperature Rating
- Hot / Tropical – 20°C to 40°C
Target Species
- GTs (Giant Trevally)
- Tarpon
- Triggerfish
- Bonefish
- Permit
Types of Flies
- Streamers
- Poppers
- Crustaceans
Additional Features
- Half-size heavy taper turns over large flies and loads modern saltwater rods quickly
- Extended head design improves distance casting accuracy and control
- Profile supports long leaders for shallow flats and clear water presentations
- High contrast rear sighter helps identify the back of the line during long runs
- Optimised for fast presentations to moving fish in hot tropical saltwater

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.
