Release the boomerang at a slight upward angle (in relation to the horizon). Distant treetops are usually a good rule of thumb. Keep it off the ground, but don't put it in the clouds!! Too low of a release angle creates a high-climbing end of the flight. A touch more release height will create a level, more consistent flight.
#1. Determine wind direction and velocity.
#2. Depending on the model throw 40-60 degrees off the wind.
If the boomerang lands in front of you, throw more into the wind. If it lands behind you, throw more off the wind. You must know wind speed and direction prior to each throw. Right handed: throw right of the wind. Left handed: throw left of the wind. As you become more proficient you will be able to handle more and more wind.
