Be sure to follow the nock and arrow requirements for the specific crossbow model you are shooting.  Failure to use the required nock will void your warranty. 

Do not use moon or capture nocks in any TenPoint, Horton Crossbow Innovations, or Wicked Ridge crossbow.

All TenPoint and Wicked Ridge crossbows are now shipped with and require the use of arrows with Alpha-Nocks.  Failure to use Alpha-Nocks or the Alpha-Brite Lighted Nock System on any TenPoint or Wicked Ridge Crossbow may void your warranty.   Alpha-Nocks and Alpha-Brites can be used safely in any TenPoint, Horton Crossbow Innovations, or Wicked Ridge crossbow manufactured by TenPoint and will not void your warranty.
