Japan’s top tungsten company is now available to the US market. The Reins TG Tungsten Down Shot Sinkers have a design that makes it easier to pull thru rocks, weeds, or brush with fewer hang ups. Reins tungsten down shot sinkers give you the ultimate performance with a specific gravity of 18.2, making each sinker 40% smaller than its lead counterpart. Reins sinkers are constructed of 95% tungsten and 5% nickel alloy making them 1.8 times as dense as lead and environmentally safe. The dense tungsten material provides a smaller profile, faster sink rate with increased sensitivity.
