The Alpha-Blaze Lighted Nock contains a one-piece Nock/LED unit that is indexed with the vanes and press fits into the arrow’s Aluminum Bushing. Upon firing the crossbow, the bowstring’s 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 twenty-four hours when activated.

The Pro Elite 20-inch carbon arrow is TenPoint’s premier 410-grain 20” carbon arrow.

Built for speed, the Pro Elite 400 is fletched slightly offset with 3″ Q2i Fusion X-II Vanes and TenPoint’s Alpha Nock HP Nock and Alpha Nock HP Nock Bushing. The Pro Elite 400 is fitted with a 58-grain aluminum insert and inspected for straightness to within .003″. TenPoint’s Alpha-Nock HP features a deep bowstring groove, a large smooth radius base, and elongated ears. Its HP Aluminum Bushing increases strength and accuracy. The string on TenPoint’s extremely narrow crossbows wraps tightly around the center of the Alpha-Nock HP resulting in straight nock travel and precision down-range accuracy, while minimizing string serving wear.
