Tuf-Line Metered Lead-Core Line features a tightly braided high-tenacity polyester multifilament yarn surrounding a 99.9% pure lead core, resulting in a smaller diameter than standard lead core lines. Its color-metered design changes every 10 yards with high-visibility dye, allowing anglers to accurately gauge depth instantly. Ideal for deep-water trolling, this line provides the extra weight needed for precise control and effective fishing in challenging conditions.
