The Scientific Anglers Sonar Striper Sinking Fly Line is engineered for anglers chasing powerful saltwater species in changing depths and conditions. Available in Full Intermediate (1.25 IPS) and Intermediate/Sink 5/Sink 7 Triple Density options, this line is built two line sizes heavy with an aggressive 30-foot front taper that loads rods deeply and drives large, air-resistant flies with ease. Whether stripers are smashing sand eels in shallow water or cruising deep drop-offs for pogies, the Sonar Striper delivers fast, accurate casts and precise presentations.
Constructed on a braided multifilament core, this line stays supple in cold to medium water temperatures while maintaining powerful turnover and control. AST Plus slickness technology ensures longer casts and lasting smoothness, while Sonar sinking technology provides exact depth control and an even descent. The Seamless Density design blends densities gradually to maintain a straight-line connection to your fly, reducing hinging and improving strike detection. Finished with welded loops and SA•ID line identification, this line is built for efficiency, reliability, and maximum performance on the salt.
The Full Intermediate version keeps flies just under the surface—perfect for shallow flats and calm tides—while the I/Sink 5/Sink 7 Triple Density gets down fast for deep rips and fast currents. No matter where the striped bass are feeding, the Sonar Striper Sinking Line keeps you connected and in control from the first cast to the final retrieve.

AST+ - A new formulation of Scientific Anglers' patented dry-slick technology provides continual line slickness over the lifetime of the line. Up to 50% slicker than the original AST and 200% more durable than the competition. Fly lines with AST Plus cast farther, float higher, and stay cleaner than any other lines ever built
Welded Loops - Exceptionally slick and strong, Scientific Anglers' 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.
S/A Line ID - 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.
Sonar - For every one fish eating on top, there are ten feeding beneath it. Scientific Anglers' 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.
Seemless Density - Seamless Density technology is a gradual mixing of densities that provides a smooth transition between disparate densities, providing less hinging and a straight-line connection to the fly as it sinks.
