The Icon combines three different vibration dampening technologies to perform at its efficiency level. The Vibasorb insert, into which is molded a vibration dampening geometric shape, features four flexible wings "flapping" out of sequence to dissipate vibration. Then, inserted is a rod that attaches rigidly to your bow to produce a reverse isolator effect. The Vibasorb insert expands into the flutes machined into the outer aluminum sleeve which ties everything together by creating a bond, resulting into a perimeter weighted gel cylinder. Ideal for today's short and quick hunting bows.
