Amplitude Smooth Infinity
Scientific Anglers Amplitude Smooth Infinity is an advanced fly line with a true infinite sink profile, engineered to sink uniformly along its entire length. This allows precise depth control for nymph and streamer presentations deep below the surface — especially valuable in strong currents, deep runs and large bodies of water.
The infinite sink pattern delivers smooth, controlled sinking without abrupt dives, giving anglers consistent contact with the fly and excellent feedback throughout the drift. Constructed with high-end core and coating technology, Amplitude Smooth Infinity produces stable loops, clean casts and reliable performance even in windy or challenging conditions.
This line is an excellent choice for anglers who prioritize deep presentations and maximum fly control with techniques such as euro-nymphing and tight-lining.
