The Hyperwhistle – Worlds Loudest Whistle
According to the listing they claim it works underwater too and features a unique radial tri-frequency design.
They claim that it’s also 8 x louder than a standard whistle. That’s going to make someones ears bleed, I remember our teacher blowing that whistle near my ears and not hearing anything else for a whole day. Luckily you’ll be wearing the provided protective ear buds.
Perfect for a range of uses, survival, police force, sports and recreation, camping, hiking, boating and much more.
The Hyperwhistle (worlds loudest whistle) also comes with a nice little lanyard to attach it round your neck.
