What is FOC?
- Front of Center (FOC) refers to the distribution of weight along the length of an arrow. A higher FOC indicates that more weight is concentrated towards the front of the arrow, which can improve accuracy and penetration when shooting.
How to Calculate FOC
To calculate the FOC of an arrow, you can follow these steps:
- Measure the Full Length of the Arrow (A): This is the total length from the throat of the nock to the back of the insert.
- Determine the Length to the Balance Point (B): This is measured from the throat of the nock to where the arrow balances.
