Nano-Pro is simply the best 100% carbon target arrow in the world! Designed for FITA, NAA and NFAA long-distance field shooting the Nano-Pro is engineered with incredibly light yet strong 46-ton carbon. Nano-Pro arrows recover even faster out of the bow than the Nano-XR while delivering the flattest trajectory and superior down-range accuracy. It has the smallest diameter of any of our target arrows, nearly eliminating cross-wind drift. Unlike aluminum core arrows, Nano-Pro arrows won’t take a set (permanent) bend, consistently holding their initial spine tolerance for several seasons!
