The Amplitude Smooth Titan GT (New for 2025) is a purpose-built tropical floating line designed to load powerful saltwater rods immediately and drive bulky patterns with authority. It’s one size heavy for fast shots, features a slick, durable coating, includes a high-contrast sighter for line management, and comes ready for salt with heavy-duty factory-style loops.
When your shot window is measured in seconds and the fly is the size of a small bird, your fly line has to do two things flawlessly: load the rod instantly and turn over powerfully. The Scientific Anglers Amplitude Smooth Titan GT was designed for exactly that mission.
The first series of lines to feature the revolutionary AST PLUS slickness additive, Amplitude will shoot farther and last longer than any other line on the market. It's slickness down to a science.
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.
Fast-load, fast-shoot taper
Titan GT is built one line size heavy, so modern fast-action saltwater rods load with less false casting and deliver quick, aggressive presentations. The head is short enough to pick up and re-cast efficiently, yet substantial enough to keep turnover stable when the wind comes up and the fly fights back.

Tropical core, salt-ready build
A stiff tropical core helps maintain performance in heat so the line behaves predictably on deck and doesn’t turn into a limp noodle in the sun. Heavy-duty braided loops simplify rigging and protect connections when you’re pulling hard on serious fish.
Line control you can actually see
A high-contrast sighter section helps you identify line position at a glance—useful when managing slack, feeding line on a run, or resetting quickly for a second shot.
Where it fits
If you’re targeting Giant Trevally or other high-impact saltwater species and you want a line that’s designed for big flies, wind, and urgency, Titan GT is the tool.
