• Auto ON: Lights activate automatically when the nock is shot, eliminating extra steps in your setup.
• LED stays on: The light remains powered until you manually unclick the nock, ensuring visibility through the entire flight and impact.
• Universal fit: Universal collars fit most arrow shafts (G, X, H, S), simplifying setup across different setups.
• Material: Polycarbonate blend nock designed to work with standard arrow shafts, including aluminum shafts, for broad compatibility.
• Color and pack options: Blue color available in 3-pack (also offered in 6-pack); other color options include Green and Red for quick identification.
