Scientific Anglers Sonar Titan WF Sink Tip Fly Line

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.
