Tenpoint Pro Elite 400 Select Features The TenPoint Pro Elite 400 Select Arrows are precision spine-indexed to increase accuracy by 33 percent over the standard Pro Elite 400 carbon arrows delivering tighter groups while maintaining the same point of impact shooters already expect. Each 20 inch arrow weighs 410 grains plus or minus 1 grain and is built with a 58-grain aluminum insert that produces a 13 percent front of center balance for stable accurate flight. The 3 inch Q2i Fusion X-II vane fletching is indexed with the arrow s construction for consistent spin and trajectory downrange. Every arrow is inspected for straightness to within .001 inches and each package is weight-grain matched within 1 grain per arrow for uniform performance across the set. These arrows are built to work with the Alpha-Blaze lighted nock system which uses a one-piece nock and LED unit indexed with the vanes and press fit into the arrow s aluminum bushing for bright illumination at the shot. The Alpha-Blaze activates automatically when the crossbow s bowstring force compresses the nock and it can be deactivated by simply pulling it straight out with no tools required. The LED lasts approximately twenty-four hours when activated and can be used in any railed TenPoint Wicked Ridge or Horton Crossbow Innovations crossbow without voiding the warranty. Sold in a 3 count package these arrows give crossbow hunters a consistent accuracy-focused option for the field.
