The Black Eagle Deep Impact Shafts are built for bowhunters demanding maximum penetration and consistency. Featuring a micro-diameter 4mm (.165") design, these heavy-hitting shafts deliver increased kinetic energy and deep impact performance. With .001" straightness and a +/- 1 grain weight tolerance, each arrow is super-sorted and spine indexed to ensure tight groupings and repeatable accuracy. Constructed from high-quality carbon, the Deep Impact shafts are built to withstand rugged hunting conditions. Each 32-inch shaft is optimized with the FOCOS 2.0 system, allowing for enhanced front-of-center tuning and performance.
