Whats in the box:Whistle

A referee whistle like no other!

Introducing the NEW Fox 40 Caul! The Caul is Fox 40's first finger-grip-style whistle designed specifically to encompass a flexible finger-grip. Composed of a strong polycarbonate body with integrated over-mold CMG technology, Fox 40 has combined the pea-less whistle and finger-grip together in one continuous design.

Dual-chamber pea-less technology, combined with years of proprietary research and development, has resulted in a one-of-a-kind all-encompassing whistle and finger-grip. The Fox 40 Caul features a sleek design and highly-durable yet flexible rubber form-fitting finger-grip. Fox 40 has evolved traditional beat pea-style technology in to a pea-less style whistle without compromising the traditional harmonized trill tone. The Caul Finger-grip Whistle has crisp loud sound and is extremely easy to blow. Whistle has an 110dB rating.
