Our team of professional archers and expert engineers are always looking for new ways to innovate and take our products to new heights.  With the all new S.O.S. (Stability Optimization System) Heavy Medal, archers are now able to directly mount an SOS unit directly to their bow using nothing more than a 5/16″ bolt (included). The Heavy Medal has a mathematically engineered and field confirmed wire unit pre-installed that provides the ultimate in stability specifically designed for a compact unit. The S.O.S. Heavy Medal can be positioned with 360 degrees of adjustability although we recommend setting the unit with wires oriented on a parallel/vertically  plane.
