Scientific Anglers Sonar Stillwater Fly Line

A stillwater specialist.

Stillwater fly fishing is all about finding the right depth, and Scientific Anglers' Sonar Stillwater Fly Line's slow-sinking Sonar technology is designed to put your fly down in the strike zone of chunky bows, trophy cutthroats, and hyper-aggressive char. Scientific Anglers gave this stillwater-specific line a clear color to reduce its overall visibility in the water, and then added a responsive monofilament core, so you can feel the slightest tug on your fly. The line also features a smaller diameter to make it easier to cast. Speaking of casting, the Sonar also features a long, tapered head that excels at making long-distance casts on windy lakes.
