The Sport Hunter Xtreme was engineered to help provide superior stabilization while conquering shot-induced vibration, resulting in the ultimate hunting stabilizer. The Sims Internal Harmonic Dampener and De-Resonator combine to effectively minimize vibration transferred from the riser to the stabilizer upon release of the arrow. The individual 1 oz. end-weights allow users to customize their stabilizer to meet the ideal balance requirements of their particular hunting bow.Together, it equals added confidence to make YOUR shot of a lifetime.
