The Scientific Anglers® Professional Series Full Sinking Fly Line is the leading choice for most anglers when they need to get their streamers and nymphs down quickly. Featuring a more uniform sink rate from tip to belly (1.25 to 8.00 ips), this weight forward Professional Series Full Sinking Fly Line offers a thin diameter which provides superior casting over other sinking lines. Designed with a single-strand monofilament nylon core, the Full Sinking line is specially coated with environmentally safe powdered tungsten for greater durability. Color: Dark Gray. Length: 90'.
