Scientific Anglers - Frequency Full Sink (Type 6) Double Sided Fly Boxes Belt loop attachmentALL PURPOSE SINKING LINES If theres a better way to fish lakes and ponds than with a full sinking line, we havent found it. The Frequency Full Sink is the perfect sinking fly line for stillwater anglers; it handles streamers and wet flies with aplomb, cuts through the wind, and features a mid length head for great line control. We built the Frequency Full Sink with two sink rates and the idea that great subsurface lines dont have to cost a fortune.
