ENGINEERING THE PERFECT LINE:

The right line can be the difference between catching a bucketload of fish and coming home empty-handed.

Some anglers think line is boring. Nothing to get too excited about. But the right line can be the difference between catching a bucketload of fish and coming home empty-handed. The truth of the matter is that line is extremely interesting, especially to the scientists at Berkley. They put enormous amounts of time and energy into engineering the perfect line for every water condition, every species, and every type of fishing technique. Discover the best line for your fishing needs and let our science help you catch more fish.

Explore Our Process

Berkley Science and Why it Matters.

It starts with research & development in our labs at our Berkley headquarters in Spirit Lake, Iowa. Here we can test our new line tech and prototypes directly on the species we’re fishing for to see how it performs with various rigs & baits.

In fact, we design, engineer, and manufacture all of our line in the same building where our scientists are working diligently to develop the most advanced fishing gear in the world.

Then we take it to the water. We test our theories in real world conditions, with real fishermen. Our Production and R&D teams work extremely close allowing us flexibility & control through production to ensure the our lines work as designed, and as intended.

Bottom Line: We refine. Test. Refine. Test again.
And refine... as much as necessary:
Until it’s scientifically proven to help you catch more fish.

Berkley Line Resources, Tips & Techniques

Discover the Right Line For You

Every fishing condition is different and requires a different type of line. Check out the science behind Berkley's freshwater lines and how to choose the ideal line for your next trip on the water.

Monofilament

Attributes

  • All purpose, forgiving and easy to handle fishing line

  • Easy to tie knots with good strength

  • High stretch, forgiving line – optimal when fighting big fish

  • Neutral buoyancy so it floats; optimal for fishing topwater baits & spinner baits

Best Bets

FLUOROCARBON INFUSED COPOLYMER

Attributes

  • Combines the manageability of Monofilament with the abrasion resistance of Fluorocarbon

  • Nearly invisible making it less visible to fish

  • Nearly neutral buoyancy - ideal for fishing crankbaits & dropshot rigs

Best Bets

FLUOROSHIELD

All around most manageable Berkley line. Offers easy casting and knot tying.

Available Fall 2020

FLUOROCARBON

Attributes

  • Nearly invisible line making it virtually less visible to fish

  • More sensitive than monofilament; great for dropshot rigs & fishing jerkbaits

  • More abrasion resistant than monofilament for shallow cranking around timber and cover

  • Naturally sinking line, maintains direct contact with bait for enhanced sensitivity and feel - optimal for flipping a jig

Best Bets

100% FLUOROCARBON

Highest abrasion resistant Berkley Fluorocarbon. Ideal for fishing in heavy cover due to high abrasion resistance. Made with 100% Fluorocarbon ensuring near invisibility under water and sensitivity.

CONVENTIONAL BRAID

Attributes

  • 3x stronger compared to the same diameter monofilament and fluorocarbon lines

  • Toughness making it ideal for fishing heavy cover

  • Highly sensitive with near zero stretch – optimal for vertical jigging

  • Virtually no line memory(coil) for long casts with buzzbaits & swimbaits

  • Ideal for making long casts to cover more water

Best Bets

x5

Berkley’s strongest conventional braid. The 5-carrier construction offers great combination of casting, toughness, manageability, and sensitivity.

Shop Now

x9

Berkley’s smoothest and long-casting braid. The 9-carrier construction of Berkley x9 allows for great blend of toughness, manageability, sensitivity, and strength.

Shop Now

FUSED BRAID

Attributes

  • Strongest line per diameter and exceptional toughness – ideal for fishing the heaviest of cover

  • Fused technology resists frays and picks – it is 4x more abrasion resistant than conventional braids

  • Highly sensitive with near zero stretch – optimal for vertical jigging

Best Bets

FIRELINE

Most abrasion resistant line in its class. Berkley FireLine Ultra 8 constructed in a fusing process so it resists picks and frays in tough conditions. Low Diameter -- better casting
