Saunders invented the industry’s first bow 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. The copies that followed all suffer from repeated string slaps. You’ve seen dramatic video of these oscillations. The Vudu™ dampeners traps the string in its recoil chamber, eliminating multiple strikes and limb shock much more effectively than any other string dampener. Several options are available to give the Vudu™ bow string silencer even more mounting punch. Note: Vudu™ in slow motion video was shot with test parts before mold mold surface was dulled.
