Non-Strobing FIT Nock: Designed to fit nearly every hunting arrow on the market the Nockturnal Fit non-strobing base nock will fit X-diameter arrows, and each three-pack of Fit nocks includes three sets of Nock Collar adapter sleeves to fit GT, S and H arrows. Each Fit nock features ultra-strong, impact resistant, clear polycarbonate nock construction encapsulating the super-bright single LED that’s activated by a patented string-activated, piston-driven linear contact switch. Like all Nockturnal nocks, the Fit is guaranteed to reliably activate immediately when the string is released, and it can be switched off quickly and easily with the newly designed Nockturnal Nock Tool, a small screwdriver or most broadhead tips via an opening in the side of the nock. With well in excess of 20 hours of lithium battery life, each Nockturnal Fit weights approximately 25 grains and will remain brightly lit for plenty of time of arrow retrieval and can be easily spotted in daylight or darkness. Available in Red, Pink, Green, Blue, Orange and White.
