Unlike calculating arrow speed, which requires a chronograph, arrow FOC can be calculated with a few measurements and some simple math. You will need the following tools to calculate your FOC of an arrow; measuring tape, pencil, permanent marker, and calculator. There are 5 simple steps in calculating arrow FOC. Feb 07, 2010 · What is arrow Front of Center, and how do I figure out my Front of Center. F.O.C is a term used to express the percentage of weight forward from the center of the arrow. Having good F.O.C. is not only important in obtaining good down range accuracy, but crucial when it comes to achieving good broadhead accuracy. In any case, I would use either calculation of FOC as a "figure of merit" for comparison between setups, rather than an exact measurement. REAL FOC explanation - The actual FOC of an arrow is dependent on the distance between the arrow Center of Gravity(CG) in front of the arrow Center of Pressure(CP).

flight records, set using relatively high FOC arrows, are challenging this concept. Hunters need fairly high FOC. Broadheads exert a steering effect upon the arrow, due to wind-shear. Fletching must overcome these “wind-plane” forces. High FOC means fletching has a longer “lever”, and more steering control.
