Description
Description
The Scientific Anglers Sonar Titan Triple Density - Int-S3-S5 Sinking Fly Line is engineered to cast like a floater while fishing like a sinker. Moreover, its fully tapered design creates a direct, straight-line connection to your streamer, eliminating the clumsy “chuck and duck” feel. Consequently, this line allows you to fish streamers with precision and control at depth.
Featuring a triple-density build, the line blends intermediate, Sink 3, and Sink 5 sections for seamless transitions. In fact, this construction ensures your flies remain in the strike zone while maintaining superior casting efficiency. Therefore, whether you are stripping streamers for trout or chasing larger predators like largemouth yellowfish, and tigers, the Titan Triple Density is built to perform.
With a short, powerful head and Shooting Texture technology, this line delivers excellent turnover, reduced friction, and longer casts. Furthermore, its braided multifilament core ensures consistent performance in temperate climates. Ultimately, the Sonar Titan Triple Density – Int/S3/S5 provides anglers with unmatched depth control and casting smoothness in a sinking fly line.
Technologies
- AST – Slickness additive that reduces friction, improves shootability and extends line life.
- Shooting Texture – Textured coating that reduces friction for longer casts, easier pick-up and added durability.
- Welded Loops – Durable welded loops front and back for reliable loop-to-loop connections.
- SA-ID – Printed line identification showing taper, weight and density for quick recognition.
- Sonar – Density-tuned sinking technology for a smooth, stable sink profile and consistent depth control.
