1. What is Gold Tip Front Center?

Front of Center (FOC) is a measurement used in archery to determine the balance point of an arrow relative to its center. It is expressed as a percentage and affects arrow flight stability and accuracy.

2. How Does the Calculator Work?

The calculator uses the FOC formula:

Where:

• \( AMO \) — Arrow length measured using AMO standard (in inches)
• \( \text{Balance From Tip} \) — Distance from arrow tip to balance point (in inches)

Explanation: The formula calculates how much of the arrow's weight is distributed in the front half of the arrow, which impacts its flight characteristics.

3. Importance of FOC Calculation

Details: Proper FOC is crucial for optimal arrow flight, accuracy, and penetration. Different FOC percentages are recommended for various types of archery (target, hunting, etc.).

4. Using the Calculator

Tips: Enter AMO length and balance from tip measurements in inches. Both values must be positive numbers, with AMO length greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the ideal FOC percentage?
A: For most hunting applications, 10-15% FOC is recommended. Target archers typically use 7-12% FOC.

Q2: How does FOC affect arrow flight?
A: Higher FOC arrows tend to be more stable in flight and penetrate better, but may sacrifice some speed.

Q3: How do I measure balance from tip?
A: Find the balance point by balancing the arrow on a narrow edge, then measure from the arrow tip to this balance point.

Q4: What is AMO length measurement?
A: AMO standard measures arrow length from the bottom of the nock groove to the end of the shaft, not including the point.

Q5: Can FOC be adjusted after arrow building?
A: Yes, FOC can be adjusted by adding weight to the front (inserts, heavier points) or back (lighter nocks, wraps) of the arrow.
