Tenpoint Pro Elite 400 Alpha-Blaze Features The Tenpoint Pro Elite 400 Alpha-Blaze arrow uses the company s Alpha-Blaze Lighted Nock a one-piece nock and LED unit indexed with the vanes that press-fits into the arrow s aluminum bushing. When the crossbow fires the bowstring s force compresses the two halves of the nock and activates the light automatically so there is no separate switch to manage mid-hunt. The nock can be deactivated just as easily by pulling it straight out until the light turns off requiring no tools. With roughly twenty-four hours of LED runtime once activated hunters get reliable illumination for tracking the shot without draining the light before it is needed. Each 20 inch carbon arrow is inspected for straightness to within .003 inches and carries a 58 grain aluminum insert giving it the consistency serious crossbow hunters expect from a premium shaft. The arrows are fletched with 3 inch Q2i Fusion X-II vanes set at a slight offset for stable flight and the finished green color makes them easy to spot in the field. At approximately 410 grains per arrow the Pro Elite 400 strikes a balance between speed and downrange energy for hunting-weight broadheads. Packaged three to a set this arrow combines Tenpoint s lighted nock technology with precision carbon construction for confident hits at extended range.
