Ross Outdoors, Phoenix. Front of center (FOC) is how far forward your arrow balances. Measure your finished arrow with the point on and we will do the math.
- Arrow length: from the throat of the nock (where the string sits) to the end of the shaft. Do not count the point or insert.
- Balance point: with the point installed, balance the arrow on a thin edge and measure from the throat of the nock to that spot.
Uses the standard Easton FOC formula. Most hunting arrows land around 10 to 15%, and many big game hunters build higher with heavier points and inserts. Want help building a setup? Call us at 602-386-1266, or find your spine with our spine calculator.
