Sonik Subsonik Mainline 1200m is a super-smooth, hi-tech monofilament designed for the carp angler who demands the very best. It is formulated using a complex extruding process that ensures maximum strength with a limited stretch factor, and it is designed to sink quickly, eliminating detection. The minimal stretch means that when fishing at range, indication is amplified greatly through the line, so bites register on the indicator and alarm quickly. Subsonik has low memory and excellent abrasion resistance, making it super tough and a good choice for the angler who fishes on snaggy waters for big carp. It also features high shock absorbency and is ultra-smooth, enabling a perfect line-lay on big pit reels, making it a strong option for the distance caster. Available in Brown, Green and Camo in five different diameters to cover all aspects of carp fishing.
