With the power and intensity of today's crossbows, the patent-pending Universal Lighted Nock System from TenPoint helps you see your shot the entire way as well as locate and recover your bolt after the shot. The three-piece Omni-Brite system begins with a nock-receiver glued into the nock-end of the arrow and indexed or aligned with the arrow vanes. The nock-receiver insert is designed to accept the LED light unit and Omni-Brite Nock unit. Combine these three pieces for an ultra-bright nock lightning system and shoot with confidence. The force of the fired bowstring activates the nock after leaving a small gap between the nock and the arrow shaft loading. The LED unit battery life is approximately eight hours. The Omni-Nock system is designed to be universal for all crossbow manufacturers. The Omni-Nock features six micro-grooves that form channels to capture the bowstring properly, eliminating indexing problems associated with moon and capture nocks.
The Universal Lighted Nock System comes in a 3-pack and includes translucent Omni-Nocks, LED Units, Nock-Receivers (for arrows with shaft sizes .297, .300, and .306I.D), a Nock-Receiver and Alignment tool, and a refletching tool.
