A boomerang is not thrown like a frisbee. It has to be thrown almost vertically, with an inclination of about 10–20 degrees and with a lot of rotation (spin). When facing the wind, throw with an angle of 30–45 degrees to the right (left-handed: to the left) of the wind. Be sure to choose a field that is big enough. Watch out for passers-by, and do not throw when people are standing in the range of the boomerang. See also the link provided in the section below.
