When you need to get your lures down to where the fish are, tuf-line lead core will get them there with total precision. Unlike other weighted trolling lines, tuf-line lead core is sheathed in tightly braided, high-tenacity nylon (instead of Dacron), and features a 99.9% pure lead filament. Both factors result in a thinner diameter than standard lines, for less water resistance, faster lure deployment, and more precise Depth calculation. Plus, tuf-line's break strength consistently runs above the pound test rating-important when trying to slow a streaking salmon on his first Bull run. Metered with a different color every 10 yards.
