Similar to a good golf swing, boomerangs require patience and practice to develop the required skill.
Some boomerangs are easier to throw than others.
Today there are over 12 countries with national boomerang teams, including a US team. People are finding boomerangs to not only be a competitive sport, but also a great addition to mountain biking and backpacking, camping trips, kite flying, and just about any other outdoor activity. Write the United States Boomerang Association for further info. Lefties will throw clockwise, while righties throw counterclockwise. All models are available left handed.
