This whistle features a pea-less design that makes a sharp, penetrating call or signal - essential for outdoor activities.
Place the bridge of the whistle on your bottom lip and make a sharp, clear sound. Use your tongue to block the passage of the air quickly, after the appropriate length of signal.
Do not blow whistle directly in a person's ear.
