Scientific Anglers Amplitude Textured Anadro Indicator Fly Line
The first series of lines to feature the revolutionary AST PLUS slickness additive, the Amplitude will shoot farther and last longer than any other line on the market. It’s slickness down to a science.
If you’re anything like us, the allure of big fish and big rivers is intoxicating. That’s precisely why we created the Amplitude Anadro. Designed with line control in mind, its extended rear taper allows you to cast a mile, mend with authority, and turn over nearly any rig imaginable—from dredging double nymphs to larger dry-dropper concoctions. Steelhead, salmon, and trout won’t know what hit them.
- Features the revolutionary slickness additive for superior shooting ability and increased durability
- Floating texture on the tip section for the ultimate in float control

The Amplitude line casts smoothly and stays on the water longer than expected. I’ve used it in fast rivers and it handles well with both nymph and dry-dropper setups. The texture on the tip helps keep the line floating, which is a big plus.

Great for long casts and precise mends. The slickness additive makes a noticeable difference in how far it shoots. I’ve tried several lines before, and this one stands out for its durability and control.

Used it on a steelhead run and it performed exceptionally. The extended rear taper allowed me to cast over a mile and still maintain control. The floating texture helped with rig stability in moving water.
