Everything is better with fun sound effects and we believe that Boomerang should be blessed with sounds as well. Luckily, the Sonic Booma is the only Boomerang that whistles as it flies through the skies. Suitable for ages 8 and above, this boomerang is fun for all the family. Designed for a guaranteed return flight and made from flexible polymer, you can fine tune your flight settings. With a 15-20 metre range, kids and adults everywhere can spend hours of fun with the unique whistling Sonic Booma.
