The details
100% Fluorocarbon
KastKing KOVERT ESSENTIAL is extruded in from Japanese Engineered and Sourced PVDF resin. Designed to sink fast with low stretch and essential features. KOVERT ESSENTIAL has outstanding quality while still offering good value.
Low Visibility
KOVERT ESSENTIAL has low visibility and small diameter making it nearly invisible underwater. When fishing for line shy fish, KOVERT ESSENTIAL is the perfect choice for ultra-clear water or when a low visibility fishing line is required to increase your catch ratio.
Fast Sinking
KOVERT ESSENTIAL is 80% heavier than water which allows it to sink quickly versus traditional monofilament line. The faster the line sinks, the quicker your bait or lure gets into the strike zone which can be advantageous for multiple fishing conditions.
Low Stretch
KOVERT ESSENTIAL has a stretch factor approximately 11% lower than standard monofilament lines. Lower stretch translates into more immediate hook sets and fewer missed fish.
