ACME Tornado 635 ( Black, White, Orange, Yellow, Green, Blue, Pink and Red)
 
The ‘Brazil’, a nickname gained because of its extensive use in that country, especially in soccer.
 
Something different in sound and appearance, very loud, 120dBA, ideal for avoiding confusion when several matches are played side-by-side.
 
Marine/water safety and sport whistle. Extremely powerful in pitch and loudness. Unique design for those that want something that stands out in a crowd.
