1. What is Arrow FOC?

Front of Center (FOC) is a measurement that describes the balance point of an arrow relative to its length. It's expressed as a percentage and affects arrow flight and stability.

2. How Does the Calculator Work?

The calculator uses the FOC equation:

Where:

• \( FOC \) — Front of Center percentage
• \( L \) — Arrow length in inches
• \( AMO \) — Balance point from nock end in inches

Explanation: The equation calculates how much of the arrow's weight is distributed in the front half of the arrow.

3. Importance of FOC Calculation

Details: Proper FOC is crucial for optimal arrow flight. Higher FOC (10-15%) improves stability for long-distance shooting, while lower FOC (7-10%) may be better for short-range speed.

4. Using the Calculator

Tips: Measure arrow length from nock groove to end of shaft (not including point). Measure balance point by finding where the arrow balances perfectly.

5. Frequently Asked Questions (FAQ)

Q1: What's the ideal FOC for Victory Gold Tip arrows?
A: Typically 10-15% for most hunting applications, but depends on your specific setup and shooting style.

Q2: How does FOC affect arrow flight?
A: Higher FOC arrows are more stable but slower. Lower FOC arrows are faster but may be less stable at longer distances.

Q3: Should I include the point when measuring arrow length?
A: No, measure only the shaft length from nock groove to end of shaft (not including point length).

Q4: How can I adjust my FOC?
A: Add weight to front (heavier points, inserts) to increase FOC, or reduce front weight to decrease FOC.

Q5: Does FOC affect broadhead flight?
A: Yes, proper FOC is especially important for consistent broadhead flight and accuracy.
