The StringTamer GII is a new and improved version of the original StringTamer. The Rear Mount design mounts to the rear stabilizer bushing of your compound bow but still allows you to mount a front stabilizer. Constructed from aircraft grade aluminum, this dampener is built to last. Featuring an ultra-soft rubber dampener that instantly stops string oscillations, the StringTamer GII quiets your bow and greatly reduces bow vibration. The Rear Mount StringTaner GII can be adjusted from lengths of 4-1/2 to 8-1/8 inches so it is compatible with virtually any bow. All of the mounting hardware you will need is included in the package, just install and go shooting.
