Why spine testing matters
Wooden shafts can vary within the same nominal spine group. Measuring each shaft helps build a more consistent set and gives you useful information when selecting shafts for a particular bow.
Use the included instructions and conversion data, and always confirm that the chosen arrow specification is suitable for your bow.
