Scientific Anglers Frequency Intermediate

Scientific Anglers Frequency Intermediate is a slow-sinking, clear line designed for stillwaters, dams, and calm river pools where subtle depth control is essential. The 1.25 ips sink rate allows flies to settle slowly into the feeding zone, while the balanced taper loads easily and suits a wide range of rod actions. Ideal for nymphs and streamers in both moderate and cold climates.
