Nockturnal Shift FIT Lighted Nocks (3-Pack) The Nockturnal Shift FIT takes the reliability of the original lighted nock and adds a major quality-of-life upgrade: an external slide switch. No more fumbling with tools or small pins to turn your nocks off after a shot; just slide the switch and you're ready for the next one. These are designed with a "one size fits most" approach, utilizing a versatile bushing system to ensure a perfect fit on almost any hunting arrow in your quiver. Key Technical Specs • Activation: Patented, string-activated piston-driven linear switch. • Deactivation: External manual slide switch (no tools required). • Battery Life: 20+ hours of lithium-powered illumination. • Durability: Impact-resistant, clear polycarbonate casing; waterproof and shockproof. • Weight: Approximately 25 grains per nock. Universal Fit Technology The Shift FIT system includes interchangeable bushings to match the internal diameter (ID) of your specific arrow shafts: • X (No Bushing): Fits .204 ID shafts. • H (White Bushing): Fits .233 ID shafts. • GT (Black Bushing): Fits .246 ID shafts. • S (Gray Bushing): Fits .244 ID shafts. Pro-Shop Tips for the Shift Nock • Consistency is Key: At 25 grains, these are heavier than standard press-fit nocks. If you are tuning for long-range precision or high-stakes hunts, remember that adding weight to the rear of the arrow will slightly stiffen the dynamic spine and affect your F.O.C. (Front of Center). • The Switch Advantage: The external switch is a game-changer for low-light practice sessions. It allows you to quickly reset without needing a specialized tool or a pocket knife, saving wear and tear on the nock housing. • Proper Seating: When installing the bushings, ensure they are seated perfectly flush against the back of the shaft to maintain true nock alignment and prevent "nock pinch" or erratic flight.
