HyperWhistle (Safety Orange

Extremely loud whistle, a little expensive for a bit of plastic, but it does the job.

I was curious as to how loud a whistle could be do I bought one of these… damn me, it’s incredibly loud! I didn’t blow it very hard first time and it still made my ears ring. You really need to wear ear plugs if you’re going to blow it hard, because it’s way louder than you’d think possible. For a whistle, it’s very expensive, but it’s really well built, very lightweight and its power is undeniable - it is easily the loudest whistle I’ve ever encountered, by a long long way. I’ve got it for emergency use, and it’s said to be audible 2 miles away, so it’s functional and very handy if you want to be heard! Don’t blow it in a small space tho - you’ll know about it if you do!!! Awesome emergency whistle, two thumbs up 👍🏻👍🏻

It does exactly what it says on the tin, it is very loud.

This whistle is not your average sports whistle; it is super loud and has a range of up to 2+ miles, an impressive eight times the range of an ordinary whistle. One of the standout features of the HyperWhistle is its incredible sound output. A sound pressure level (SPL) of up to 142dB is eight times louder than your typical whistle. This makes it perfect for various situations, whether boating, attending sporting events, ensuring life safety, camping, hiking, or even police use. The durability of this whistle is also worth noting. It is built to withstand all weather conditions, making it a reliable companion no matter the environment. Whether it's raining, snowing, or even underwater, the HyperWhistle will continue to function flawlessly. I also appreciate the attention to detail in the design of this whistle. Its unique radial tri-frequency design ensures that the sound is carried efficiently and effectively, allowing it to be heard from a distance. Additionally, the whistle is naturally buoyant, adding an extra layer of convenience for water-related activities. The HyperWhistle comes with reusable hearing protectors, which is a thoughtful addition. This ensures that you can protect your ears while still enjoying the powerful sound of the whistle. The easy clip-neck lanyard is also a handy feature, allowing you to keep the whistle within reach at all times. It's worth mentioning that the HyperWhistle is a patented design (US8925478), which speaks to its uniqueness and quality.
