Scientific Anglers Sonar Titan Triple Density Sink INT/3/5 Fly Line
The 5 inch per second sink rate makes this a great line for achieving depth, or fishing shallow with a fast retrieve.
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.
Features
- Loads quickly and delivers the biggest flies to the furthest targets

This line changed how I fish streamers. It casts like a floater but sinks straight, so I can get my flies to depth without constant adjustments. The sink rate is spot-on and the turnover is smooth. I’ve been using it for two weeks and it’s already my go-to for deep water.

The triple density makes a noticeable difference in how the line performs. I used to have to adjust my retrieve constantly, but now I can fish deeper with confidence. The cast is easy and the line holds its shape well in the water.

Great sink rate and solid performance. A bit stiffer than standard lines, but that’s expected with the tungsten mix. Works well in both deep and shallow conditions. Slightly more expensive, but worth it for the consistency.
