Scientific Anglers Frequency Intermediate is a slow-sinking WF fly line available in AFTM classes #5–#7. It has a total length of 25.9 m and sinks at 1.25 ips, allowing flies to be presented just below the surface.
The line is especially effective for fishing streamers and nymphs. Its mid-length head supports good line control, while the thin diameter helps the line cut through the wind.
Frequency Intermediate features a braided multifilament core, AST technology and a welded loop. It is designed for freshwater fishing and is particularly well suited to stillwaters and streamer fishing in rivers.
