Nockturnal lighted nocks make it easier to locate your arrows and track their flight during periods of low light conditions. A piston driven contact switch ensures that the LED illuminates when the arrow is fired. The lithium battery will keep the light on for up to 20 hours. Shoot it at dusk, and you can still find your arrow at dawn! No prep work is required, the nocks can go directly from the package to the shaft. Just insert, and you are ready to shoot.
