Spin Racer Carbon Boomerangs are part of the "Spin Racer" series which are some of the top selling boomerangs in the world. A little heavier than other Spin Racers, the carbon fiber version is also more durable but it is designed more for older teenagers or adults. Throw overhand with lots of "spin"! Approximately a 35 yard flight radius in light to medium winds. The hole in the middle stabilizes the boomerang for more flight control even in medium winds.
