Scientific Anglers Mastery Anadro Fly Line
If you’re anything like us, the allure of big fish and big rivers is intoxicating. That’s precisely why we created the Anadro fly line. 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.

I’ve used this line on several cold-water rivers and it handles long casts with ease. The mending is smooth and the line doesn’t tangle when switching between nymphs and dry flies. Great for steelhead and trout.
Tim Kerr –
The line performs well in medium water conditions. I appreciate the extended rear taper—it makes it easy to cast over 100 yards without losing control. A solid choice for dry-dropper setups.
Evan Johnston –
Used it during a salmon season and found it reliable in windy conditions. The line holds up well under pressure and allows for precise mends when working with indicator rigs.
Donna Dowd –
It’s a bit heavier than other lines I’ve tried, but the control and distance are worth it. Works well with streamers and poppers in open water.
