Barnett's popular HeadHunter™ arrows just got an upgrade with innovative strobing lighted nocks. These rugged polycarbonate half-moon nocks feature multicolored strobing lights, tested to outperform static lights when identifying shot location and retrieving arrows in lowlight conditions. The arrows use a pressure-sensitive design to begin strobing on impact, and they'll continue strobing for up to three days. When not in use, easily disable the strobe lights with an on/off toggle switch at each arrow's nock base. No assembly required " begin using the HeadHunter 20" Lighted Arrows straight out of the box. Includes three arrows per pack.
