Scientific Anglers Sonar Titan GT
Designed for the most demanding saltwater scenarios, the Sonar Titan GT is built for two jobs: GT fishing and bluewater pursuits like marlin, dorado, and wahoo.
Featuring a floating running line paired with an intermediate sinking head (1.25 ips), this line helps keep large flies in the strike zone while maintaining control in current, chop, or offshore movement.
A short, powerful head and compact front taper deliver fast rod loading and strong turnover of oversized flies — essential when throwing heavy baitfish patterns or presenting quickly to moving targets.
Built on a 65 lb. tropical monofilament core, the Sonar Titan GT is engineered to perform under extreme heat and pressure without softening or failing when it matters most.

FAQ
What makes the Sonar Titan GT suitable for bluewater fishing?
The Sonar Titan GT features a floating running line with an intermediate sinking head (1.25 ips), which keeps large flies in the strike zone and maintains control in choppy or moving water. Its strong, compact design supports fast rod loading and effective turnover when targeting large fish like marlin and dorado.
Is the line durable in high-temperature environments?
Yes, the Sonar Titan GT is built with a 65 lb tropical monofilament core designed to withstand extreme heat and pressure without softening or breaking under stress.
Can this line be used for heavy baitfish patterns?
Yes, the short, powerful head and compact front taper allow for strong turnover and effective presentation of oversized baitfish patterns, making it ideal for GT fishing and fast-moving targets.

Used the Sonar Titan GT for marlin fishing off the coast. The floating line kept my flies in the zone even in choppy conditions. The 1.25 ips head worked well with large patterns. Very reliable in heat and saltwater exposure.
Lillian Robertson –
Fished with this line during a dorado season. The compact taper and strong head allowed quick turnover. No line breakages even with heavy flies. Performs well in offshore currents.
Simon Arnold –
Good performance in moderate to heavy conditions. The sinking head keeps flies where they need to be. A bit stiff to cast in light wind, but overall solid for saltwater use.
Tracey Terry –
Used it for both GT and wahoo fishing. The tropical monofilament core holds up well in hot weather. No issues with line softening or breaking during long sessions.
