What is FOC and why is it important for archery?

FOC (Front of Center) measures how much of an arrow's weight is forward of its balance point. Proper FOC (10-15%) improves arrow flight stability, accuracy, and penetration. Too little FOC makes arrows unstable, while too much can affect trajectory.

How do I calculate arrow weight accurately?

Arrow weight is calculated by adding the shaft weight (GPI × length), point weight, insert weight, fletching weight (count × individual weight), and nock weight. The Perfect Arrow automatically calculates this using real manufacturer specifications.

What spine should I use for my bow?

Spine selection depends on your draw weight, draw length, arrow length, and point weight. Generally, higher draw weights require stiffer spines (lower numbers). Use manufacturer spine charts or The Perfect Arrow's calculator for precise recommendations.

How many arrows should I have in my quiver?

For hunting: 6-12 arrows minimum. For target archery: 3-6 arrows per end. Having extras allows for practice, replacement of damaged arrows, and ensures consistent performance across your set.

What's the difference between carbon and aluminum arrows?

Carbon arrows are lighter, faster, and more durable but more expensive. Aluminum arrows are heavier, less expensive, and easier to tune but can bend. Carbon-aluminum hybrids offer benefits of both materials.
