RIO GT Mono Tippet
The ultimate Giant Trevally tippet with larger mono diameters and higher break strengths to prevent being cut off on coral and sharp structure, while supple enough to seat larger saltwater knots properly.
Most giant trevally guides will tell you that the best way to land these incredibly powerful fish is to keep them from running far enough to cut you off on structure. Strong fluorocarbon might come to mind, but it sinks much faster than nylon at larger diameters and affects fly presentation. That’s why the standard leader configuration for GT fishing has become level monofilament with break strength in the 100-130lb range. RIO’s GT Mono is perfect in this application, striking the ideal balance between strength and knotability. Available in extremely high break strengths with excellent knot security and durability.
| Break Strength | Available Options |
|---|---|
| 100lb | Standard configuration |
| 130lb | High-performance option |
FAQ
What makes RIO GT Mono different from other monofilament lines?
RIO GT Mono offers higher break strength and better knot security compared to standard monofilament, with a balance of strength and suppleness that allows proper seating of saltwater knots without sacrificing durability on sharp structures.
Is the GT Mono suitable for use in coral-rich environments?
Yes, the higher break strength and resistance to cutting on sharp structures make it ideal for use in coral-rich environments where fish are likely to run into hard surfaces.
Does the GT Mono sink faster than nylon in larger diameters?
No, the GT Mono does not sink faster than nylon at larger diameters. It maintains consistent performance in water, unlike fluorocarbon which sinks more quickly.

Used this line on a recent giant trevally encounter in the reef zone. It held up well under heavy runs and didn’t cut on the coral. The knot stayed secure even after several hours of fishing. Strong and reliable.
Chloe Lewis –
Fished with GT Mono during a deep-water trevally session. The line resisted cutting on sharp rocks and maintained good presentation. Knots seated easily and didn’t loosen during the fight.
Dominic Mackay –
Good strength and feel. A bit stiffer than expected, but works well for the intended use. No issues with knot security or durability in rocky areas.
Brian Simpson –
Perfect for GT fishing. The 130lb version handled a large fish that ran hard without breaking. No snagging on coral, and the line stayed intact throughout the fight.
