Sci Angler Frequency Full Sinking Fly Line
If there’s a better way to fish lakes and ponds than with a full-sinking line, we haven’t 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 don’t have to cost a fortune.

I’ve used the Sink 3 version on a quiet lake and it sank smoothly without tangles. The mid-length head gives me better control when casting. Windy days are manageable thanks to the thin profile. Great for streamers and wet flies.
Stephanie Robertson –
Felt like a solid choice for stillwater fishing. The sink rate is consistent and the line doesn’t snag easily. I prefer the Sink 6 for deeper water, but the 3 is good for shallower zones.
Carol Gray –
The line performs well in both calm and slightly windy conditions. The braided loop on the Sink 6 version makes tying on leaders easier. I’ve used it for several days and it holds up well.

Good value for the sink performance. It sinks steadily and doesn’t drag. The mid-length head helps with casting accuracy. Not ideal for fast-moving streams, but perfect for lakes and ponds.
