Scientific Anglers Sonar Titan Full Intermediate

Scientific Anglers


Scientific Anglers Sonar Titan full intermediate lines are aggressive lines! Made to provide excellent turnover with big heavy flies. These lines are two line sizes heavy. Which loads rods quickly for less false casts to get your fly to its target. Less false casts means more time fishing, which means more fish! These are a favorite of ours here at Pacific Fly Fishers for shallow water bass, Salmon, and Sea-Run Cutthroat off of the beaches in Puget sound. The Sonar Titan Full Intermediate sinks at 1.25 inches a second which will give you a tighter connection to your fly as well as keep it the zone while stripping flies off the beach or in a lake.
