Molten Deevo whistle


The DEEVO® is a superior quality whistle designed specifically to suit the professional volleyball referee. Inspired by the powerful song of the blue whale, the Deevo was designed to cut through noise and resonate in all directions, ensuring that it can be heard throughout the entirety of the court. Its unique construction produces a thick and clear-cut high-pitched tone with a strong rising sound that instantly stops the game. A unique beat tone is created by the interference of two different tones measuring 4.10 kHz and 3.74 kHz. 

Beautifully presented in a custom-made presentation box with accompanying information flyer and basic lanyard.
