Advanced science and technology makes this the most efficient, loudest whistle ever produced by Fox 40. Extremely easy to blow, the Sonik Blast cannot be overblown and emits sound power that exceed 120 dB. The clear loud blast carries over the loudest crowds, ambient noise, and over long distances. Won't freeze, stick or jam. Mounted on a rubberised thermoplastic fingergrip for convenience.

Unique twin-chamber pealess design with four sound resonators.

Every colour, every model. AusRef stocks them all.
