1. What is IBO Speed Standard?

The IBO (International Bowhunting Organization) Speed Standard provides a standardized method for measuring arrow speed from compound bows. It uses specific parameters to ensure consistent comparisons across different bow setups.

2. How Does the Calculator Work?

The calculator uses the IBO speed formula:

Where:

• Draw Weight — Bow's peak draw weight in pounds
• Arrow Length — Length of arrow in inches
• Arrow Weight — Total arrow weight in grains
• K — Conversion constant (typically 2.5-3.0)

Explanation: The formula calculates theoretical arrow speed based on bow efficiency and arrow properties.

3. Importance of IBO Speed Calculation

Details: IBO speed helps archers compare bow performance, optimize arrow setup, and ensure proper arrow selection for hunting and target shooting.

4. Using the Calculator

Tips: Enter draw weight in pounds, arrow length in inches, and arrow weight in grains. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the standard IBO test setup?
A: Standard test uses 70 lb draw weight, 30" arrow length, and 350 grain arrow weight.

Q2: How accurate is the IBO speed calculation?
A: The calculation provides theoretical maximum speed. Actual speed may vary based on bow efficiency and other factors.

Q3: Why is arrow speed important?
A: Arrow speed affects trajectory flatness, kinetic energy, and penetration power for hunting applications.

Q4: What factors affect actual arrow speed?
A: Bow efficiency, cam design, string material, arrow spine, and fletching all impact actual arrow speed.

Q5: Is higher speed always better?
A: Not necessarily. Higher speed often means more noise/vibration and requires proper arrow tuning for accuracy.
