Cardiosport GT 1 Heart Rate Monitor

The Lumenok lights up instantly with shot inertia, and replaces existing arrow nock of Gold Tip arrows. Available: Single pack, Three pack. Color: Fluorescent Orange, Fluorescent Green. Sports and Outdoors

Requires no magnets, no glue; it contains no Switch or any other moving parts. Nothing to attach to the Bow or glue into the Arrow to make it work. When nock is fully seated against the "electrically conductive" end of the carbon or aluminum Arrow shaft, the Lumenock lights. Wiggling the nock Back and forth in the Shaft breaks the electrical contact between the Arrow Shaft and the Lumenock, causing the Light to go off. Lumenock will automatically be activated upon the Release of the Arrow when shot. Will remain lit For up to 40 hours or until retreived and is turned off by wiggling it Back and forth. Nocks will operate hundreds of times. Lumenock : The original. Made to fit in the Super Uni Nock system.
