The details
100% FLUOROCARBON WITH XTREME PERFORMANCE
KastKing Kovert Xtreme fluorocarbon fishing line is engineered using Japanese PVDF resin. Designed with lower stretch and higher abrasion resistance. Kovert Xtreme fluorocarbon fishing line loads differently than traditional monofilament, requiring greater force to stretch the line. Kovert Xtreme is exceptional when used as a main fishing line or as a leader material.
LOW LIGHT REFRACTION
Kovert Xtreme fluorocarbon fishing line has a low light refractive index making it virtually invisible underwater. Kovert Xtreme fluorocarbon fishing line is perfect for highly pressured water or ultra-clear conditions when you need a low visibility fishing line to increase your catch ratio. Fish just don’t see it underwater.
FAST SINKING
Kovert Xtreme fluorocarbon fishing line is 78% heavier than water which makes it sink super-fast versus traditional monofilament line. Fast sinking is a distinct advantage in many fishing situations where getting the bait or lure in front of the fish quickly, increases catch rates.
HIGHER ABRASION RESISTANCE
Kovert Xtreme fluorocarbon fishing line has a higher abrasion resistance than standard fluorocarbon lines. Kovert Xtreme fluorocarbon fishing line easily cuts through heavy cover. Higher abrasion resistance equates to fewer lost fish due to line failure.
Fast sinking, great handling, low visibility, shock resistant, abrasion resistant, Kovert Xtreme 100% fluorocarbon fishing line is sure to meet the most demanding angling conditions. Available in Clear color from 4 pound through 50 pound. Spooled onto 25 and 50 yard dispenser spools and 200 yard filler spools. KastKing Kovert Xtreme fluorocarbon fishing line and fishing leader delivers confidence in your lines performance under the most demanding conditions.
