Being able to see your line is often critical in helping determine bites when your line is only swimming off after a subtle bite. Night fishing presents one of the greatest challenges to seeing your line effectively. For years only nylon lines were available in high visibility under black lights. Sunline has designed the ultimate night fishing fluorocarbon line. It is highly visible under black light, so an angler is able to see his lines at all times. Night FC is 100% fluorocarbon providing all the benefits of fluorocarbon lines like high abrasion resistance, lower stretch and greater sensitivity. It is available in two color choices clear blue or the Hi-Vis Yellow color that is the most visible version. The clear blue is a great choice for dual purpose use for morning and evenings as you transition in and out of total darkness and then works well at full night. The Hi-Vis Yellow color is the brightest version under a black light and gives you highest visibility.
