Stainless steel add-on weights that let you tailor the weight of your indicator head to suit any situation. They fit all Solar indicator heads, including the new iPro heads for the Titanium system, as well as many other manufacturers' indicator heads. Each weight simply screws into the base of your indicator head, and your indicator chain or arm then screws into the base of the weight. Multiple weights can be used on one head to create the perfect overall weight.
