The FlexBall is not a tipical damper device. We thought as a complex piece for solve two questions respect the bow vibrations. Two types of vibrations was produced after the shoot, the first produced by the general movement that the archery impuls in the shoot execution pulling the bow, the second was produced for the impact of the string to the limbs, that is going onto the stabilizer. Our design is the most advanced on the market. Why? the innercore is the heart of the FlexBall, designed for the vibrations transmited onto the stabilizer, always protected of the external conditions, always working. The outside is the skin of the FlexBall, looking for eat the mayor movements during the shot execution and protecting the FlexBall innercore of he external condicions. The devide is a FlexBall the most advanced damper till today.
