Scientific Anglers Sonar Titan Sink 3/Sink 5/Sink 7 Fly Line
Get this: we took one of our most popular tapers, the Titan, drenched it in various mixtures of tungsten powder, and created a triple-density sinking fly line that will absolutely change the way you fish streamers forever. This is a fully tapered sinking line, so it casts like a floater, but provides a straight-line sinking connection to your streamer. The days of chucking and ducking are finally over. Welcome to the triple-density revolution.
- Loads quickly and delivers the biggest flies to the furthest targets
- Excellent turnover due to short, powerful head
- Triple density construction provides straight-line connection to fly
- Shooting Texture reduces friction, providing longer casts, easier pick-up, and increased durability

FAQ
What makes the triple-density construction different from standard sinking lines?
The triple-density construction uses tungsten powder mixed into the line to create a straight-line sinking profile, ensuring the fly reaches the target without wobbling or drifting.
How does the shooting texture improve performance?
The shooting texture reduces friction during casting, allowing for longer casts and easier fly pickup while improving overall line durability.
Is this line suitable for deep water streamer fishing?
Yes, the straight-line sinking connection makes it ideal for deep water streamer fishing, delivering flies directly to target zones with minimal drag.

I’ve used this line for several weeks now and it’s made a huge difference in my streamer fishing. The sink is consistent and I can reach deeper areas without having to adjust my casting technique. The cast feels smooth and the line holds up well after repeated use.
Peter Marshall –
Switched from a standard sinking line to the Titan Sink 5 and noticed a clear improvement in accuracy. The fly goes straight down and lands exactly where I want it. Great for targeting structure in deeper streams.

The line casts well and the sink is reliable. A bit more expensive than others, but the performance justifies the price. I’m still getting used to the weight, but it’s definitely better than previous lines I’ve tried.
