A digital tool assists archers in selecting the correct arrow shaft stiffness, often referred to as spine, based on factors like bow draw weight, arrow length, and point weight. This process is crucial for accurate and consistent arrow flight. For example, an archer using a high draw weight bow will generally require a stiffer spine than someone with a lower draw weight.
Proper spine selection is fundamental to archery performance and equipment longevity. Mismatched arrows can lead to erratic arrow flight, reduced accuracy, and potential damage to the bow or arrows themselves. Historically, archers relied on experience and charts for spine selection, but online resources now provide a more precise and convenient method.
