Scientific Anglers Sonar Titan Triple Density Sink 3 / Sink 5 / Sink 7 Fly Line - Olive / Charcoal / Black

Scientific Anglers Sonar Titan Triple Density Sink 3 / Sink 5 / Sink 7 Fly Line - Olive / Charcoal / Black is built for anglers who want a true sinking fly line that still casts with the control and turnover of a floating line. Designed around the proven Titan taper, this triple-density sinking fly line loads quickly, carries big streamers with authority, and creates a straighter connection to the fly for better depth control and more direct presentations. The olive, charcoal, and black color scheme matches the line's segmented density design, while the braided multifilament core is tuned for temperate to cold-water fishing.

Key Features

• Triple-Density Construction: Sink 3, Sink 5, and Sink 7 sections help maintain a straight-line connection to the fly for better bite detection and solid hook sets.
• Titan Taper Performance: A short, powerful head loads rods fast and turns over large streamers for trout, bass, pike, musky, and stripers.
• Shooting Texture: Textured coating reduces friction for longer casts, easier pick-up, and improved durability over repeated use.

Scientific Anglers designed this Sonar Titan line for streamer anglers who need to fish subsurface efficiently without the sag common to many full-sink lines. The fully tapered design helps the line cast cleanly, track well, and stay connected through the retrieve, whether you are covering stillwater structure or stripping big flies through current.

Across the lineup, the line features a 33.5-foot head and 105-foot total length, plus welded loops for fast rigging. For anglers targeting fish that feed below the surface, Scientific Anglers delivers a sinking fly line that combines depth, casting ease, and dependable turnover in one streamlined package.
