The Sonar Titan series features lines built on our popular Titan Taper, only, instead of floating, all of these sink. From fishing just below the surface in a small stream to dredging blue holes in the ocean, nothing helps you throw large flies better than the Sonar Titan lines.
Each of these lines are built two line-sizes heavy. However, they are designed to be used on rods with the designated line weight. We build them oversized to help turn over large flies and chuck big flies at even bigger fish.
Freash or salt water, it doesn't matter. We have a Sonar Titan built for the fish you're after.

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.

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.

When your quarry has eyes the size of dinner plates (almost), every little bit of stealth helps.
