Scientific Anglers Frequency Intermediate Fly Line
There are times when you need to get your fly underwater, but not too far below the surface. The Frequency Intermediate fly line is designed for that exact scenario. With a slow sink rate, it effectively pulls streamers and wet flies under surface chop, placing them where fish are actively feeding.
- Especially effective for fishing streamers
- Thin diameter cuts through wind
- Ideal for use in stillwater situations
- Mid-length head for enhanced line control
- Sink Rate: 1.25 ips (Intermediate)
- Braided multifilament core
| Specification | Value |
|---|---|
| Sink Rate | 1.25 ips (Intermediate) |
| Line Type | Intermediate Fly Line |
| Core Material | Braided Multifilament |
| Best Use | Stillwater, river streamers in chop |
FAQ
What makes the Frequency Intermediate line suitable for stillwater fishing?
The slow sink rate and mid-length head provide better control and accuracy when placing flies near the surface, making it ideal for stillwater conditions where fish are often found just below the surface.
Can this line be used effectively in rivers with surface chop?
Yes, the thin diameter and slow sink rate allow it to cut through wind and surface chop while still delivering streamers to the desired depth, making it effective in rivers as well.
Is the sink rate adjustable or fixed?
The sink rate is fixed at 1.25 ips (Intermediate) and is designed for consistent performance in typical fishing conditions.

This line performs well in calm lakes. The slow sink rate helps get streamers down without dragging. I noticed better control when casting in light wind. Great for wet flies and streamers.
Victor Scott –
Felt like a natural fit for my stillwater setup. The thin profile cuts through wind better than my previous line. Slightly more sensitive, but that’s a plus for detecting subtle bites.
Harry Hughes –
Used it in a river with chop and it held up well. The mid-length head gave me better control during casts. Streamers went down smoothly and stayed on target.
Sarah Anderson –
Good value for the sink rate and performance. Not as fast as a sinking line, but perfect for getting flies to the right depth without sinking too deep.
