The Tunin' stick is an excellent stabilizer that reduces noise and vibration. The Accu-Flex Material is super lite and makes this the best stabilizer in its class, weighing just 4 oz. Adjustable from 4 to 6 inches, just rotate the Tunerz Accu-Flex sleeve while pulling away from the bow. Return to position by rotating and pushing back on the shaft. The Tunin' Stick works great by itself and greatly enhances other Tunerz Products.
