Tenpoint

The Match 400 Alpha-Blaze arrow provides bright illumination at the shot and the same point of impact as the unlighted arrows. The Alpha-Blaze Lighted Nock contains a one-piece Nock/LED unit that is indexed with the vanes and press fits into the arrows Aluminum Bushing. Upon firing the crossbow, the bowstrings force compresses the two pieces and activates the lighted nock. Deactivate the easy on/off Alpha-Blaze lighted nock by pulling the nock straight out until the light turns off no tools required. The LED light of the Alpha-Blaze system lasts for approximately eight hours when activated.
