Frequently Asked Questions
What is a good FOC for hunting arrows?
Typical hunting FOC falls in the 10-15% range, balancing accuracy and penetration. Many bowhunters prefer 12-19% for added broadhead forgiveness at longer distances.
How do I measure my arrow balance point?
Rest the fully finished arrow (point, vanes, and nock installed) on a thin edge and slide it until it balances level. Measure the distance from the nock end to that balance point.
How is FOC calculated?
FOC equals the balance point distance from the nock minus half the arrow length, divided by the arrow length, times 100. A balance point ahead of center gives a positive FOC.
How do I increase my arrow FOC?
Add weight toward the front by using a heavier broadhead, brass insert, or weighted point, or shorten the shaft. Reducing rear weight, such as lighter vanes, also raises FOC.
