FAQ

Frequently asked questions

Does our Whistle work underwater?


Yes!

After you begin blowing the HyperWhistle, the air clears the chambers and allows the whistle to sound underwater.

An interesting side note: Sound travels faster in water than in air, so the HyperWhistle frequency is higher underwater.
