TECHNOLOGY'S BLACK MAGIC...... Saunders invented the industry's first string dampener in 1997...The Deadly-Quiet™. The patented design absorbed excess string energy, helped get the arrow off the string faster to increase arrow speed and kept the string path aligned. Many have copied these concepts but all suffer from one common ailment - noise from repeated string slaps after the arrow leaves. You've probably seen high speed video of these dramatic oscillations. VUDU™ traps the string in the pistons recoil chamber, eliminates multiple resonant strikes and absorbs residual energy from the bow. Other string stop can not make these claims. The VUDU™ X-link™ mount uses eight nylon tipped set screws to lock firmly on a 3/8 inch cable-rod. An optional X-link™ with pivot pin adds extra reach and offset. Also available are front and rear riser-port options.
