Scientific Anglers Frequency Boost is a half-size heavy floating line designed for anglers who want extra power without sacrificing control. It loads easily and suits a wide range of rod actions, excelling with larger or heavier flies. A versatile mid-length head makes it a great all-round choice for trout and mixed-species fishing in rivers, dams, and stillwaters.
