Saunders offers more Deadly-Quiet string silencers than ever. The Extreme model mounts on a 3/8" cable rod and sports a variable 3/8" to 1 5/8" offset. This variable offset allows the dampener to be set at the ideal location. Regardless of which model you choose twang, vibration and overdraw string slap vanish. The Deadly-Quiet's shock absorbing piston, smooths and deadens string travel without the abrupt dead stop of other systems. To make the system even more absorbent the contact head is a super soft gel. Protecting this gel from wear is a durable synthetic sheath. Superior deadening and better for your bow...now that's a winning combination.
