Soft, comfortable and flexible form-fitting fingergrip – a referee whistle like no other!
The Caul is Fox 40’s first fingergrip-style whistle designed specifically to encompass a flexible fingergrip. Composed of a strong polycarbonate body with integrated over-mould CMG technology, Fox 40 has combined the pealess whistle and fingergrip together in one continuous design. It has evolved traditional pea-style technology without compromising the traditional harmonised trill tone. Crisp loud sound and extremely easy to blow.
Sound Power: 110 dB
