Gamakatsu G-Line Shock Leader Monofilament Line 0.47mm 15kg 50m

Gamakatsu G-Line Shock Leader — Reliable Monofilament Leader for Hard-Fighting Fish

The Gamakatsu G-Line Shock Leader is a purpose-built monofilament (single-strand nylon) leader line designed to handle the sudden shock loads of the strike, the abrasion of rough substrates, and the sustained pressure of the fight — all in one versatile 50 m spool.

High Knot Strength and Easy Handling

A leader is only as strong as its weakest knot, and the G-Line Shock Leader is engineered with outstanding knot strength so connections to lures, hooks, and main line hold firm under load. The supple material is easy to work with, ties cleanly even in cold conditions, and lies flat on the spool without excessive memory.

Tough Where It Counts — Abrasion and Flexibility

The combination of high abrasion resistance and genuine flexibility sets this leader apart for lure fishing. It is robust enough to withstand contact with rocks, gravel, and submerged debris, yet soft enough to let artificial lures move naturally and enticingly. The high breaking strain of 15 kg on a diameter of 0.47 mm means you get solid strength without unnecessary bulk in the water.

Choose the Right Variant

The G-Line Shock Leader is available in a range of diameters and breaking strains to match your target species and technique. Select the strength that fits your setup — lighter diameters for finesse spinning, heavier gauges for big-game or surf work:

• 0.47 mm / 15 kg — lighter spinning and lure presentations for pike, perch, and similar predators in snag-free to moderately structured water

• 0.57 mm / 20 kg — stepped-up strength for larger predators or heavier lures

• 0.62 mm / 25 kg — robust choice for demanding conditions or stronger fish

• 0.87 mm / 50 kg — heavy-duty leader for big-game, surf, or extreme abrasion situations

• Additional variants available (specifications not confirmed)
