The Beiter Balance Clip is a small, but important tool.
It helps to determine the balance point of the arrow and
allows to easily calculate the F.O.C. (=front of center),
the percentage of the balance point from the mid of the arrow.
To do this, simply clip in the Balance Clip on the arrow and
move it until you find the point of balance. Measure the distance
in mm from the balance point to the arrow point (=S) and the
overall arrow length (=L).Following the calculation formula of
the F.O.C in %: FOC%=((L/2)-S)*100/L e.g. L = 780, S = 290 is
a F.O.C. of 12,82%. Balance Clip #1, e.g. for arrows with smaller
diameter, e.g. carbon,aluminium-carbon 6.5 mm
