Archery bow having improved design to absorb shock and reduce vibration

Abstract

The present invention generally relates to an improved archery bow having a greatly enhanced ability to absorb shock, vibration and sound. In order to achieve improved sound and vibration dampening, the bow riser, and optionally the bow limbs are coated with an energy absorbing and/or dampening coating. The coating is permanently attached to the riser and/or the limbs of the bow and greatly reduces undesired vibrations and/or noise generated by and during the archery bows use, without interfering with the performance of the bow. The invention also relates to treestands and archery accessories having a low noise profile.
