Tired of blowing a whistle in sports? Can't get your cheers across? Need to alert others in the mountains, outdoors, or on a dark road in case of an emergency? This electronic whistle solves those problems! Ultra-loud 125dB. Just press the button and a "Pee-yoo!" warning sound rings out. The cylindrical horn concentrates the sound, making it reach much further and more effectively than a whistle. Compact and doesn't get in the way, whether you put it in your pocket or hang it around your neck. Hygienic, as you don't need to put it in your mouth. Easy to take out and share with multiple people. Switch between 3 different tones to suit the situation. Useful for referees in games, traffic control, security, self-defense, crime prevention, and even bear deterrents in the mountains. It's reassuring to have one in your bag for emergencies.
