The ACME Thunderer Finger Grip Whistle is the official whistle of Hockey Canada and its member branches. The ACME Whistle is built with solid brass and a cushioned finger grip while delivering a powerful tone. Popular among ice hockey referees, the Thunderer blasts a slightly higher pitch sound compared to the standard deep tone among other brands.

It has an easy blow, and instant response that makes the Thunderer a great option for new users and coaches alike. AMCE also used a lead-free design and a waterproof speed pea to ensure a clean sound each and every time!
