Introducing the Percussion Plus medium thunderer whistle

The Percussion Plus large thunderer whistle produces a large deep tone and a far carrying sound for use in all environments. Made from tough, shatterproof polycarbonate, the iconic design is sturdy and durable whilst also being easy to blow.

The PP155 is most commonly used by sports referees but has a variety of other uses including for dog trainers, and even government officials and private security firms.

With a reliably consistent sound, the thunderer is a pea whistle so you can produce a variety of sounds by adjusting the airflow to produce a rolling trill with a range of effects.

Made in the UK

Percussion Plus whistles are manufactured in Birmingham and were carefully developed over a number of years. Outstanding craftsmanship and strict quality testing ensure every whistle is of the highest standard.

Developed in 1884 and used by every generation since, the thunderer was the world’s first sports whistle. To this day, the whistles are made by hand using traditional techniques and most of the original equipment.
