Endorsed by NFL pro quarterback Russell Wilson, this Aerobie Sonic Fin will have you throwing like a pro. Its hollow gyroscopic core creates incredible aerodynamic lift in the air, resulting in throws travelling up to 90 metres. Everyone has a different type of throw, and thanks to the adjustable fins you can move and alter them to align perfectly with your natural spin. And with its customisable calibration ring, it can be adjusted to suit left and right-handed throwers, so everyone can get in on the fun. It also features a whistle that is activated when thrown in the air, which will add more of a wow factor to your already incredible throw. Compete against your friends and see who has the best and longest throw with the Aerobie Sonic Fin.
