Features
- Fluorocarbon Leader Line – KastKing FluoroKote fluorocarbon fishing line is a premium combination of fluorocarbon and co-polymer, making it virtually invisible in the water. The invisibility can increase angler’s catch rate, especially in clear water situations.
- Exceptional Performance – The combination of the two materials maximizes the advantage of fluorocarbon invisibility with the low memory and superior castability of copolymer. So you can have similar qualities and performance of fluorocarbon.
- Higher Abrasion Resistance - Low Stretch, high strength, superior abrasion resistance, higher density, and greatly reduced visibility make KastKing FluoroKote Fishing Line a great upgrade from mono line and ideal low cost alternative to fluorocarbon line.
- Stronger Fluorocarbon Line – The diameters of the FluoroKote fluorocarbon leader line are less than KastKing Copolymer Fishing lines or other monofilament lines, resulting in a smaller, stronger line that gives you more reel capacity and increased depth with diving baits.
- Fast Sinking – KastKing FluoroKote Fluorocarbon fishing line sinks faster with low absorption. The unique fluorocarbon materials make the line extremely durable, offer great knot strength, and exceed in sensitivity. KastKing FluoroKote Line is extremely versatile, giving anglers piece of mind to fish almost any conditions and techniques with confidence.
