Hallmark's patented two-chamber pealess whistle. Sonic Science perfects the whistle. Our patented two-chamber design eliminates the pea (cork ball) normally needed to produce a "trill". Instead, two harmonically tuned air chambers create a wave energy phenomenon called a "beat". As a result, the Fox 40 whistle produces an extremely loud, high penetrating "trill". And because there's no pea to stick and impede sound, you can't overblow a Fox 40 and it won't freeze up in the colder months. Available in 2 colors, size Small only. 


Features:
  • Patented two-chamber design eliminates pea
  • Pea-less design won't freeze up in colder months
