Frequency Sink Tip Fly Line

Streamers were meant to be fished low and dirty, so get that meat whistle down low and in front of fish fast with the Scientific Anglers Frequency Sink Tip Fly Line. Great for steelhead, salmon, smallmouth bass, or trout, this durable fly line excels when casting big streamers and multiple nymphs. The mid-length head provides anglers with more control of their line at long distances, and the sinking, ten-foot tip pulls your fly beneath the surface quickly.
