The Scientific Anglers Sonar Saltwater Intermediate Full Clear fly line is built for stealthy presentations in demanding saltwater environments. Designed with a full intermediate sink rate, this line allows flies to ride just below the surface, making it ideal for spooky fish that won't tolerate the shadow of a floating line. Its completely clear construction provides unmatched invisibility, ensuring subtle, natural presentations in clear flats, calm bays, or nearshore waters. The intermediate design also helps anglers maintain direct contact with the fly, improving strike detection and hook-setting power in wind or waves. Available in a wide range of sizes from WF-7-I through WF-12-I, this line is versatile enough for everything from bonefish and redfish to tarpon and other large saltwater species. Built with the durability, slickness, and reliability that Scientific Anglers is known for, the Sonar Saltwater Intermediate Full Clear line is a must-have for anglers who demand precision and stealth on the flats.
