Garvee Handheld 3-Tone Electronic Whistle, Loud Durable Emergency Survival Lanyard for PE Teachers Referees Coaches Outdoor Use, Blue

Details

• Loud 3-Tone Adjustable Sound: Boasts high decibel output that cuts through noise, audible in both small and open spaces. 3 adjustable tones (controlled via side slider) offer versatility beyond traditional whistles—perfect for different scenarios. Note: Avoid pointing the speaker at ears to protect eardrums.
• Hygienic No-Blow Design: Eliminates the need for mouth-blowing, preventing germ transmission from shared use. Hand-operated control is cleaner and easier to sanitize than traditional whistles—ideal for shared environments like sports teams or training sessions.
• One-Button Easy Operation: Simple off-1-2-3 side slider for power and tone adjustment, with a front thumb control button. Power on, press to sound—one-button operation makes it convenient for referees, coaches, or emergency use. Not a toy; keep away from children.
• Handheld with Lanyard & Batteries: Crafted from high-quality plastic for a smooth, one-hand grip. Includes a lanyard to prevent loss, plus 4 button batteries (no extra purchase needed)—ready to use right out of the box.
• Widely Versatile for All Scenarios: Combines all functions of a traditional whistle—ideal for PE teachers, referees, coaches, pet training, outdoor camping, hiking, emergency survival, archery, or firearms instruction. High sound penetration suits indoor and outdoor use.
