Scientific Anglers Sonar Titan Sink Tip Fly Line
So you know where the fish are holding. You’ve done your research. But you just don’t know how deep they are. Luckily, the SONAR Titan Sink Tip fly line offers a variety of solutions for all of your depth-finding needs. Just below the surface? Try the Sink 3. Holding steady in the shadowy depths? Get the Sink 6. Experimentation is the name of the game, so maybe it makes sense to try them both. Built on our popular Titan profile to allow you to turn over even the biggest streamers while you’re searching for the biggest fish.
- Two line sizes heavy for loading quickly and delivering the biggest flies to the furthest targets; use designated line weight for your rod
- Excellent turnover due to short, powerful head

I used the Sink 3 in a clear stream and found fish right at the surface. The line turned over smoothly and kept the fly stable. Great for beginners trying to learn depth patterns.

Switched to the Sink 6 in a deep lake and noticed a big difference. The line stayed put in the deeper zones and helped me locate fish that were previously hard to find.

The Titan profile makes it easy to cast long distances and still have good turnover. I’ve used both models and they perform well in different conditions.
