Scientific Anglers Frequency Full Sink - Old Box

Same line as current model just in the Old Box

All-Purpose Sinking Lines - Type 3 & Type 6 

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. SA built the Frequency Full Sink with two sink rates and the idea that great subsurface lines don’t have to cost a fortune.
