The Scientific Anglers Sonar Titan 3D is a specialized full-sink fly line engineered for delivering large streamers and weighted flies to deep-holding Great Lakes steelhead and salmon. Its triple-density construction (I/3/5 sink rates) maintains a straight connection from rod to fly through the water column, while the aggressive front taper turns over heavy intruder patterns and articulated streamers with authority.
