GEEHUA 2 STKS Rvs Sport Fluitje, Scheidsrechter Fluit met Lanyard Luid Crisp Sound Fluit voor Leraren Ambtenaren Outdoor Sport Emergency

Stainless Steel Sports Whistle, with Lanyard Loud Crisp Sound Whistle for Emergency

Brill highly recommend

Short sharp blow and it works. It's not the most piercing whistle I've had but the current children are well behaved so it works for them. I'd want a louder whistle for outdoor use.

Used for hen do games. Great, hardly. Good value.

The harder you blow, the louder this sounds, so you can just give a quick, short blow for a soft whistle, or blow long and hard for a louder whistle. This is good if you just want to get attention but don't want to deafen yourself or people nearby.It comes clipped to a cord so that you can hang it around your neck, or clip it to your belt or existing lanyard.There are 2 in the set, so one for you and one for someone else, or a spare for when you lose the first one.
