All other fingergrip whistles are a standard whistle adapted to use a grip design - the Caul is the first model designed purely as a fingergrip whistle from scratch. Composed of a strong polycarbonate body with an integrated over-mould cushioned mouth grip for your protection, Fox 40 has combined the pealess whistle and fingergrip together in one continuous design.

This creation resolves the issues referees often face with other fingergrip whistles, with a compact pealess design in virtually indestructible polycarbonate, integrated cushioned mouthgrip to reduce impact on teeth, low profile to reduce the chance of getting snagged or knocked, and flexible fingergrip to absorb impact energy.

Dual-chamber pealess design for up to 110dB of sound power, these are very popular with basketball and hockey referees!

Every colour, every model. AusRef stocks them all.
