Review on 🔊 The Original Worlds Loudest Whistle: HyperWhistle - Up to 142db Loud, Long Range, for Referee, Coaches, Instructors, Sports, Teachers, Life Guard, Self Defense, Survival, Emergency uses by Josh Maher

I bought this whistle because I work in a high school. If there's a student fight, we'll get reinforcements. All have normal sports whistles. They work well for calling for help and quite well during gameplay. HyperWhistle is a game changer. A fight broke out on Wednesday. I turned on the afterburner to stop him. I blew my whistle when I was about seven feet from the struggling students. They were so shocked at how LOUD the whistle was that they stopped fighting! I tried to lead both students into the office by the hand. One fought back. I blew the whistle again and grabbed her hand as she tried to cover her ears. The bottom line was that they would rather reach the principal's office quietly than hear me whistle a third time. A disciplinary referral is better than a hospital referral. *** 01/28/2019 I still stand by my original recommendation. I broke quite a few fights with him. The students know that sound and he understands that you don't want to be near him. That puts ANY rape whistle to shame. When someone is near you and you don't want them to, this whistle will send that message. *** February 1, 2020 My whistle works great. My director became a believer and bought one for himself. Yesterday, with his help, I managed to catch a fleeing cell phone thief. She tried to run. When I blew the whistle next to her, she tripped and fell to the ground. The noise caught the attention of the school inspector. The phone and the naughty student recovered.
