Compatibility ruleThe groove must be indexed square to the string on every shot. If the odd-coloured (index) vane is not down, the string can sit on the rim of the nock and dry-fire the bow.Ravin warrants only its own clip-on nock; any other nock design negates the 5-year warranty. The clip physically captures the string so it cannot slip off the bolt at 400-plus fps.
