The Beatmaster is the official choice for international volleyball and beach volleyball referees.
Made in Japan from a durable ABS resin, the Beatmaster exclusively features the official FIVB logo.
The ergonomically engineered design aims to reduce referee fatigue when holding the whistle for long periods of time.
Mikasa also readjusted the basic design and improved airtightness and efficient airstream, which achieves a superior, stable sound.
A thorough study of how players hear the whistle sound during volleyball games helped develop Mikasa's optimum sound.
The customised 'no cork' design delivers a precise and sharp sound that can be heard above loud crowds in large venues.
