Scientific Anglers Sonar Striper Intermediate

Scientific Anglers SONAR Striper Intermediate Fly Line

1.25 ips sink rate. Short powerful head. Built for the striper-specific angler.

The Scientific Anglers SONAR Striper Intermediate is the Northeast-focused intermediate fly line built specifically for striped bass anglers. The short, powerful head loads quickly and delivers the biggest flies to the furthest targets, even in the wind that defines striper fishing along the Northeast coast. The full intermediate sink rate of 1.25 IPS gets your fly just below the surface where most stripers feed, and the short front taper means superior turnover even with bulky bunker patterns or large bucktail streamers. Built on a braided multifilament core for cold-water flexibility and durability. Four weights cover the full striper rod lineup from 7wt through 10wt.
