Scientific Anglers Frequency Sink 23 Float/Sink4 is a sinking-head fly line designed specifically for fishing with Booby flies and other floating fly patterns. The line's advantage lies in its ease of casting and handling while wading. A fully sinking line can be challenging in shallow water, but this line combines the best of both worlds with its sinking tip and floating body.
The sinking portion of the line is long and heavy enough to reach the desired depth, while still allowing for powerful and smooth casts that help you target deeper areas. If needed, you can use a sinking polyleader to achieve even greater depth.
Scientific Anglers Frequency Sink 23 Float/Sink4 - Features:
- Sinking tip and floating body
- Easy to cast and handle
- Especially suitable for fishing with Booby flies
- Option to use a sinking polyleader for additional depth
Keep your line clean to ensure optimal performance. Regular cleaning with soap and water or cleaning pads improves the line's floatability and durability. Clean the line every 2-3 fishing trips or whenever you notice dirt affecting its performance.
