Scientific Anglers Sonar Titan Big Water Sink 6+ Fly Line

In designing our SONAR Big Water Taper series, Scientific Anglers had one specific goal in mind: to create the world’s strongest fly line. Built on the industry’s first 100-lb. monofilament core, the SONAR Titan BWT Max Sink is built for the blue-water beasts of your dreams (or nightmares). With a super-fast sinking head and a core capable of pulling semi trucks from the depths (hyperbole), this is a line for 15-weight rods and fish that weigh more than you do.
