Nockturnal brings their revolutionary lighted nocks to the next level with the Shift Nock series! They provide a vital indication of where your arrow hit the animal, and also aid in locating your arrow if you miss. They utilize the innovative string-activated, piston-driven contact linear switch, but also feature a thumb-activated switch that can be used to activate/deactivate the illumination. The internal LED and batteries are protected by an ultra-strong, impact resistant, polycarbonate casing, and are both waterproof and shock-proof. Includes 2 nocks per pack.
