Sonik Subsonik Monofilament Line 1200m 0.38mm 9.98kg Clear

Sonik Subsonik Monofilament Line — Long-Distance Bite Detection for Serious Carp Anglers

The Sonik Subsonik (Subsonic) is a high-tech monofilament engineered for demanding freshwater carp fishing, combining low stretch, low memory, and a fast-sinking profile in a 1200 m bulk spool.

Sensitive at Distance, Strong at the Hook

Produced through a complex extrusion process, the Subsonik achieves a tight balance between breaking strength and limited stretch. With 9.98 kg breaking strain at 0.38 mm diameter, this clear variant delivers reliable bite registration even when fishing at range — critical when big carp are feeding well beyond casting distance on open waters.

Built for Punishing Conditions

The line is exceptionally smooth, which promotes clean lay onto large big-pit reels and aids casting distance. Its high abrasion resistance stands up to gravel bars, snags, and hard lake beds, while the low-memory construction means it comes off the spool tangle-free session after session. Fast-sinking behaviour keeps the line pinned down, reducing surface drift and helping the rig fish more effectively.

Choose the Right Variant

The Subsonik range covers a broad spectrum of diameters, breaking strains, and colours to match your water and tactics. Lighter diameters suit open, snag-free venues; heavier options are better for close-range, weedy, or feature-heavy swims.
