- No Assembly Required: Ready for immediate use out of the package.
- Lightweight Design: Each nock contributes minimal weight to the arrow for consistent flight.
- Durable Construction: Engineered for repeated use in various archery conditions.
3. Compatibility
Nockturnal-G lighted nocks are designed for arrows with a .165 inch inside diameter. This includes, but is not limited to, popular arrow models such as:
- Victory VAP
- Easton Acc
- Easton 4mm Axis Long Range
- G-UNI
Always verify your arrow shaft's inside diameter before installing to ensure a secure and proper fit.
4. Setup and Installation
- Prepare Arrow Shaft: Ensure the inside of your arrow shaft is clean and free of debris.
- Insert Nock: Gently push the Nockturnal-G nock into the arrow shaft. Apply firm, even pressure until the nock is fully seated. Do not force the nock, as this may damage it or the arrow shaft.
- Verify Fit: The nock should fit snugly within the arrow shaft. A loose fit can affect arrow flight and nock activation.
- Test Activation: Before shooting, lightly press the nock against a hard surface or use a bowstring to simulate activation. The LED should illuminate. If it does not, refer to the Troubleshooting section.

5. Operation
- Activation: The Nockturnal-G nock is designed to activate automatically upon release of the arrow. The force of the bowstring engaging the nock causes the internal switch to close, illuminating the LED.
- Deactivation: To turn off the lighted nock after use, gently pull the nock straight back from the arrow shaft approximately 1/8 to 1/4 inch until the light turns off. Alternatively, a small tool like a paper clip or the specialized Nockturnal tool can be used to depress the activation pin until the light extinguishes. Avoid twisting the nock during deactivation.
6. Maintenance and Storage
- Cleaning: Keep the nocks clean from dirt, mud, and other debris. A soft, damp cloth can be used for cleaning. Ensure the nock is dry before storage.
- Battery Life: The integrated battery provides approximately 10 hours of continuous illumination. Battery life may vary based on environmental conditions and usage.
- Storage: Store nocks in a cool, dry place away from direct sunlight and extreme temperatures. Ensure nocks are deactivated before storage to preserve battery life.
- Inspection: Regularly inspect nocks for any signs of damage or wear. Replace damaged nocks immediately to ensure safety and performance.
