The Fox 40 Sonik Blast CMG delivers a distinct, loud, clear 120 dB blast that can be heard up to a mile away — with a Cushioned Mouth Grip made of thermoplastic for superior grip and teeth protection during long stretches with the whistle held in your mouth. The 2-chamber pealess design has no moving parts to freeze, jam, or deteriorate, can't be overblown, and its chambers self-clear when submerged.
