The OPTIMUS. Built on the platform of the ONE stabilizer, we have improved this design and made everything lighter, more streamlined and kept all the performance! Our award winning SANDTRAP technology stops bow movement while aiming and minimizes noise and vibration. This technology also stops forward bow movement on the shot, keeping you on target longer. We eliminated the external rubber dampeners and replaced them with our internal silicone dampers. This aids the SANDTRAP to further reduce vibration. We went back to the drawing board on this series and took all the weight out of the stabilizer as we possibly could, while still maintaining our well known durability and legendary performance. The result is a stabilizer like no other with the majority of the total stabilizer weight at the endcap away from the riser. This provides the most stable shot possible. These are the lightest bars we have ever made! .500 diameter for the thinnest, wind cutting performance. 8" bar weighs 2.3 ounces(500 series) Each stabilizer is shipped with two of our knurled 1 ounce weights.(listed weight not including these additional weights)
