Molten Referee Whistle Valkeen with Flip-Grip – Reliable signals for referees
The Molten Valkeen referee whistle with Flip-Grip is a professional whistle designed for use in various team sports. It combines precise sound production with a well-thought-out grip concept for safe handling even in intense game situations.
The patented Flip-Grip enables fast and secure gripping of the whistle – ideal for smooth transitions between blowing and hand signalling.
The powerful, clear sound cuts through noisy playing environments and ensures that your decisions are clearly perceived by all players and coaches.
The lightweight design at only 113 g reduces fatigue during long assignments – no annoying pulling on the cord or in the corner of the mouth.
The discreet black colour meets the high standards of neutral game officiating and matches standard referee uniforms in nearly all sports.
What sets the Molten Valkeen whistle apart
Unlike simple pea whistles, the Valkeen is specifically tailored to the needs of referees in team sports. The Flip-Grip mechanism was developed so that the whistle remains within reach throughout the game – without fumbling or inconvenience. The precise tuning of the air channel and sound chamber produces a consistently clear tone that stands out from background noise even in crowded halls and stadiums.
Ideal for active referees and aspiring officials
The Molten Valkeen is particularly suitable for referees in basketball, football and handball – whether at club level, school or recreational tournaments. For beginners looking for their first whistle, this model offers a professional foundation without excessive complexity.
How to use the Molten Valkeen whistle
Hold the whistle with the Flip-Grip between thumb and index finger – the opening mechanism unfolds the bracket and secures the whistle in your hand. After blowing, fold the bracket back: the whistle is locked in place and does not dangle annoyingly on the cord. For optimal sound projection, exhale steadily and firmly – without overblowing.
