Explained: Arrow Spine

In this second installment of Nocked and Ready to Rock for 2016, John Dudley talks about arrow spine.

The spine of an arrow refers to how much that arrow flexes. You want some flex in your arrow, but not too much, which makes choosing an arrow with the correct spine critical for accuracy.

Dudley talks about how an arrow’s spine affects accuracy, before outlining the factors archers need to consider in determining the correct arrow spine for their setup. Finally, he talks about the arrow manufacturers’ charts bowhunters need to refer to when picking an arrow shaft.
