The Centrum Premier combines ±0.001-inch straightness tolerance, NO SPINE Technology, premium high modulus carbon construction, and the ARCOS system to deliver elite-level accuracy and consistency. What is NO SPINE Technology? NO SPINE Technology is Altra's proprietary manufacturing process that helps improve tunability and consistency by reducing traditional spine-related variables. Are components included with the shafts? Yes. Each shaft includes the A.R.C.O.S. Insert/Outsert System and nocks. How accurate are these arrows? The Centrum Premier features an industry-leading straightness tolerance of ±0.001 inches and is weight matched to within ±1 grain per package. What type of target should be used? Altra recommends foam-style targets when using arrows equipped with the ARCOS system. Bag-style targets may cause the outserts to become lodged in filler material, potentially damaging the arrow or ARCOS components.
