Scientific Anglers Sonar Stillwater Parabolic Sink Fly Line Dark Green/Charcoal/Dark Green, WF-5-S

Sure, the SONAR Stillwater Parabolic Sink sounds scientific, and thats because it is. These lines sink in a U-shape through the water column, suspending flies just above the bottom and creating enticing action with each strip. Built with 10- and 20-foot textured hang markers, these lines are a stillwater anglers dream and something many fish will never have seen before.
