Scientific Anglers Sonar Titan Triple Density

Triple-Density Line for Throwing Big Streamers.

The SONAR series takes your fly and puts it right in front of the fish. Whether you’re throwing streamers for trout, big flies for muskie, or even fishing stillwaters, we have the perfect sinking line for you. Get down, and stay down, with SONAR.

Two line sizes heavy for loading quickly and delivering the biggest flies to the furthest targets; use designated line weight for your rod
For use in moderate and cold climates; braided multifilament core

Advanced Shooting Technology

Scientific Anglers’ patented dry-slick technology provides continual line slickness, allowing the line to shoot farther as it moves through the guides. Lines with AST easily shed dirt, algae, and other parasitic drag particles, allowing lines to cast farther, float higher, and stay cleaner than traditional lines.



Scientific Anglers Line Identification

Meet the Scientific Anglers Line Identification System. SA•ID is an innovative line-marking system allowing you to identify your lines at a glance. Wonder if a shooting head is 200 grain or a 300? Just look at the SA•ID. The SA•ID can be found on the first 1-2 feet of the tip section of your line.



Shooting Texture

The Scientific Anglers Shooting Texture features precisely replicated hemispherical divots, similar to those found on a golf ball’s surface. This evolution of our texturing technology has less texture on its surface so it feels like a traditional fly line but performs with the benefits of texturing. The result is a line that lasts longer, floats higher, casts easier, and, most importantly, fishes better.



Sonar Sinking Technology

For every one fish eating on top, there are ten feeding beneath it. Our SONAR sinking technology takes flies to where the fish are: beneath the surface. Using proprietary tungsten formulations and unique tapering, the SONAR sinking technology gets flies down, and keeps them there.



Welded Loops

Exceptionally slick and strong, our Welded Loops produce smoother casts and easier turnover with a seamless fly-line-to-loop transition, making for softer landings and cleaner pickups. The sleek design also maintains buoyancy for improved fly-line flotation and enables quicker connections between fly line and leaders or fly line and backing.
