Tungstens heavy alloys concentrate the maximum weight into the smallest possible space. As a result, a tungsten weight forces a lure or bait to increase its sink rate, reaching the desired depth more quickly than similarly shaped Lead weights will. Tungsten alloy weights also create twice the sound of lead weights, assisting in attracting the attention of fish. Swimerz Tungsten Barrel sinkers are highly desirable for fishing around rock or debris covered substrates as they are significantly harder than lead and will maintain their shape, also being much smoother in their finish than lead sinkers. Swimerz Tungsten sinkers are also widely used as counterweights in models, including slot cars, trains, boats, and as a counterweight, or ballast, in sporting items such as golf clubs, tennis rackets etc. Available in weights 1/8oz, 3/16oz, 1/4oz, 3/8oz, 1/2oz, 3/4oz, 1oz.
