Tornado Referee Whistle
This is the loudest whistle available as far as we know, designed for use in loud stadiums. It has no pea to jam, is easy to blow and has been used by football referees for years. It has a double pitch for clarity of sound both close and distance.
Comes with a warning- use ear defenders for prolonged use. It should certainly alert the timekeepers of the race start!
