Scientific Anglers Sonar Titan GT - New for 2025

When the bite is down, the water is deep, or the fish are glued to structure, you need a line that does two things well: get your fly to the right zone and keep it there. The Sonar Titan GT is built for that job. It’s designed around decisive turnover and strong energy transfer so bigger flies, heavier rigs, and wind don’t turn your day into a workout.

This is a “cover water” tool. It helps you fish fast and efficiently—cast, sink, strip, repeat—without constantly fighting the line or guessing whether your fly is actually in the lane. The feel is aggressive enough to drive a heavy setup, yet controlled enough to keep tracking clean and predictable. Whether you’re pulling streamers for trophy trout, hunting aggressive lake fish, or working salt-adjacent scenarios where depth and speed matter, this line is designed to keep you fishing instead of adjusting.

Best For

• Streamer fishing for big trout and aggressive predators
• Stillwater stripping, points, ledges, and drop-offs
• River runs where depth and speed are the trigger
• Anglers who want a sinking line that feels powerful and efficient

New for 2025, the Titan GT is for anglers who want their sinking system to feel deliberate: quick load, confident turnover, and dependable depth management.

*** Please Note: Sonar Titan Pelagic is a "cut to fit" customizable fly line. The line does not have welded loops. Instead the line comes with braided loops and instructions for attaching after the line is customized.

You've traveled half way around the world in pursuit of a fish that will test every single piece of your gear, you shouldn't have to worry about your fly line failing. With our 65lb. Tropical-core design these lines are designed to perform when it counts.
