BerkleyTrilene 100% Fluorocarbon 0.017in 0.43mm - Durable Clear Line

Our review of the BerkleyTrilene 100% Fluorocarbon 0.017in | 0.43mm finds it best suited to anglers who need a nearly invisible, heavy duty leader or main line that holds knots and withstands abrasion. The bottom line: this line delivers professional-grade shock and knot strength while remaining virtually invisible underwater, which helps land wary fish without spooking them. It is a dependable choice for serious weekend anglers and pros who need a 10 lb break strength in a 200 yd spool and expect reliable casts and fights.

Key Features

• 100% Fluorocarbon Construction: Provides a refractive index close to water so the line is nearly invisible to fish, improving presentations to wary species.
• Optimal Impact Strength: The PVDF formula offers exceptional shock and knot strength to handle sudden head shakes and hard strikes.
• Abrasion Resistance: Durable formulation resists wear from structure, teeth, and rough cover to reduce line failures during battles.
• High Strength per Diameter: The 0.017in | 0.43mm diameter yields a 10 lb | 4.5 kg break strength while keeping bulk low for smoother casts.
• Generous Spool Length: The 200 yd | 182 m spool gives enough line for frequent use and multiple rigs before re-spooling.

Who It's For

The BerkleyTrilene 100% Fluorocarbon 0.017in line is ideal for anglers targeting finicky freshwater species or any situation where low visibility of the line improves hookup rates. It suits those who prioritize knot reliability and abrasion resistance during long fights or when fishing around structure.

Less ideal are anglers who need extremely light breaking strengths under 10 lb or those who rely exclusively on extremely long casting distance from very thin-diameter braid; braided lines still offer thinner diameters relative to strength for long casts, so consider braid or a lighter fluorocarbon size if casting distance is the main priority.

Pros & Cons

Pros

• Consistently praised for strong knots and smooth handling, making it reliable for hookups.
• Nearly invisible underwater, which improves bite detection on wary fish.
• Great abrasion and shock resistance, reducing breakoffs around structure.

Cons

• At 10 lb break strength and 0.017in diameter, it is thicker than some alternative lines for extreme long-distance casting.

Specifications

Our Verdict

The BerkleyTrilene 100% Fluorocarbon 0.017in is a smart buy for anglers who need a stout, low-visibility line that reliably holds knots and resists abrasion. Its combination of durability, shock resistance, and near-invisibility makes it good value for those focused on hookups and clean presentations in freshwater and pressured fisheries.

Frequently Asked Questions

Is this line truly invisible underwater?
Yes, the 100% fluorocarbon PVDF construction has a refractive index similar to water, making it much less visible than monofilament.

What is the break strength of this diameter?
The 0.017in | 0.43mm diameter is rated at about 10 lb | 4.5 kg break strength and comes on a 200 yd | 182 m spool.

Will it cast as well as monofilament?
It casts well for a fluorocarbon of this diameter and is noted by customers to be smooth and reliable, though braid may cast longer for the same strength.
