Scientific Anglers Sonar Striper I/S5/S7 Fly Line - Yellow/Charcoal/Black

The Scientific Anglers Sonar Striper I/S5/S7 Fly Line - Yellow/Charcoal/Black is built for anglers who need to get large flies down quickly and keep them tracking straight in the strike zone. Designed for striper fishing in both freshwater and saltwater, this full-sinking fly line uses a short, powerful head and short front taper to load fast, cast big patterns with confidence, and deliver strong turnover at distance.

Key Features

• Triple-density sinking design: Intermediate, sink 5, and sink 7 sections help create a straighter connection to the fly for improved depth control and better strike detection.
• Fast-loading taper: A compact, powerful head helps rods load quickly, making it easier to cast heavy baitfish flies and other large patterns.
• Braided multifilament core: Built for dependable performance with the strength and feel needed for aggressive subsurface fishing.

Scientific Anglers designed this Sonar Striper line for anglers targeting fish that feed below the surface, where much of the action happens. The 30-foot head and 105-foot total length give you a useful balance of casting efficiency and line management from boat, surf, or flats edges. The Yellow/Charcoal/Black color layout also makes it easier to identify the line's sections while rigging or managing retrieves.

Whether you are stripping bunker patterns for striped bass or fishing other large streamers in moving or still water, the Scientific Anglers Sonar Striper series delivers the sinking performance, turnover, and control serious fly anglers expect from a dedicated subsurface fly line.
