KastKing Kovert Fluorocarbon Fishing Line and Fluorocarbon Leader Description:

  • 100% FLUOROCARBON – New KastKing Kovert 100% pure fluorocarbon fishing line is engineered and manufactured in Germany to be the best fluorocarbon fishing line and fluorocarbon leader material available. Kovert Fluorocarbon Line delivers exceptional performance when you need a sensitive, shock-resistant, ultra-low visibility clear fishing line or fluorocarbon leader for tough conditions.
  • VIRTUALLY INVISIBLE UNDERWATER – Kovert 100% Fluorocarbon clear fishing line and fluorocarbon leader material have a light refractive index similar to water making it virtually invisible underwater. It’s perfect for highly pressured water or ultra-clear conditions when you need a low vis fishing line to increase your catch ratio.
  • PERFECT AS MAIN LINE OR LEADER MATERIAL – Greater force is required to stretch Kovert 100% Fluorocarbon fishing line than standard monofilament line. This can be an exceptional benefit when using it as a mainline or when using it as a fluorocarbon leader line material attached to low stretch braided or super lines. Kovert Fluorocarbon line is also waterproof, so it has the same strength, sensitivity, and handling characteristics under the water as it does dry.
  • FAST SINKING/HIGHLY SENSITIVE – Kovert 100% Fluorocarbon line is 80% heavier than water so it sinks much faster than traditional mono fishing lines. This can be a distinct advantage in many fishing situations. Its highly sensitive nature also improves strike detection and improves the feel of your fishing line while increasing your hook-up ratio.
  • LINE DISPENSER PACKAGE –KastKing Kovert 100% Fluorocarbon fishing line and fluoro leaders are perfectly spooled in amazing 50Yds/200Yds packages with a line dispenser function. It keeps your excess fishing line in the package without tangling or getting loose. The 50-yard spools are perfect small, easy-to-store, leader spools.  Use the larger 200-yard spools to fill reels or when you use a lot of fluorocarbon line as fluoro leader material.
