LimbSaver TwistLox Split Limb Bow Vibration Dampeners help keep you in stealth mode even after the shot. Noise, or lack of it, is a critical part of bowhunting strategy, especially when a second shot opportunity presents itself. Often, additional noise results from vibration from the limbs, riser and string. For archers, suppressing handshock and noise during the shot can be frustrating. LimbSaver solves this common problem with an innovative dampener design. LimbSaver TwistLox Split Limb Bow Vibration Dampeners install easier than any suppression system ever designed. Simply slide, twist and lock them into your bow's parallel limbs to finally put an end to noisy shooting and handshock. Includes 4 dampeners per pack. Weight: 1.1 oz. each. Made in USA.
