Industry leading 100% SK99 German made ultra-low stretch flying lines. Pair the 2m Pro Line Extensions with your 22m Pro lines to create 24m lines for extreme boosting. The Navigator / Pro Control Systems are supplied with 22m Lines, with a split at 12m, which is far enough for the bar to travel to completely depower our largest kite when you flag out. Remove the standard 10m top section of line and replace with the 2m pro lines for 14m lines ideal for school or foil racing. IMPORTANT: We recommend switching all your lines at the same time. Different age lines may have different wear characteristics.The Pro Lines are compatible with the Navigator Pro and Navigator, but mixing left and right rear lines with different diameters may affect kite performance.
