This online tool assists archers in determining the appropriate arrow spine for their specific bow setup. It considers factors such as draw weight, arrow length, and point weight to recommend a spine value that optimizes arrow flight and accuracy. For example, a recurve archer with a 28-inch draw length, shooting a 45-pound bow with 100-grain points, might be suggested a spine of 500.
Proper spine selection is critical for consistent arrow flight and accuracy. A mismatched spine can lead to erratic arrow behavior and poor groupings. This digital resource simplifies the spine selection process, making it more accessible to archers of all experience levels. Historically, determining appropriate spine often relied on complex charts, experienced intuition, or trial and error. This automated approach removes much of the guesswork and allows for more precise and efficient arrow tuning.
