The Original Worlds Loudest Whistle up to 142db Loud, Very Long Range, for Referee, Coaches, Instructors, Sports, Teachers, Life Guard, Self Defense, Survival, Emergency uses

This whistle is quite large in size and not so easy to conceal when hung around the neck. But the sound is really really loud. U tested it in an open park, and it was deafening to say the least. It is well made and rugged and lives up to it's name as the World's loudest whistle.

I'll start by saying, do not be like me; this is not something to foolishly test out indoors, because, you easily run the risk of making yourself deaf, or, at least having some serious hearing damage. Don't be like me, and use this inside, as excited as you, rightfully, are, to test this the second it is delivered. I read, for a long time, what the "world's loudest whistle" was, and, found out about the Hyperwhistle. I can say, as the headline suggests, that this fits that bill, and then some. Pros: - This is easily the loudest whistle you can buy, so it is suitable for all sorts of applications. - Price is fantastic for what you get. - I tested this, on a long, pier, which is in a very rural area, with a friend, and the claims about distance, are accurate, if not a bit undersold; this could easily be heard much further away. - Does not require an immense amount of lung power to use, whilst still being ear-piercingly loud. - Unbelievably durable/well crafted - I wish more plastics/polymers were made to this standard, or, all were. This whistle can take a fall onto concrete from 3 stories, and it can be left outside (neither of those are anything I'd recommend), for 4 days straight, in a predominately saline environment, which does a good job at least tarnishing almost anything in less time, and, this shows NO signs of damage or anything; it looks brand new still after all of that. Cons: - I have absolutely nothing negative to say about this, and I have tried to find something.... - It isn't a "con", but, it sure would be nice, if this had the "NHL referee style" two finger ring guard, somehow implemented on future designs, or perhaps a variant product. The lanyard can do that job as well though. All said, this is a very very very, loud, whistle. I could see this being easily used for a means of self-defense, that would alert literally anyone, and buy someone time to escape whatever danger they are in. If more lifeguards had this - maybe they do use these, no idea personally - that also would be a very effective and affordable way to save lives, and, again, alert anyone on a beach. This is something that I would suggest anyone who wants to go hiking, or is into ANY form of exploration, be it nature, urban, etc. to have with them, as it really is tough enough to withstand anything, it CAN be used underwater (tested this myself, and even remembered to use earplugs), and, well, to avoid being more redundant, this could easily save your life, and it is so well made, that I've already been suggesting this to other people. I have nothing negative to say about it at all, because it's got the perfect price point for the quality, and accurate, if not modest, claims they make in their advertising for the product. 10/10 - 5/5 Stars - Excellent product, which I HIGHLY recommend! - RevengeOfThePiff

So, this guy is VERY loud. It has three chambers, unlike the majority of whistles, which have one. I liked that it was sturdy and made of thick plastic. The three chambers and the thick plastic mean it won't fit comfortably in your pocket. It comes with a wrist lanyard, but depending on what you're using it for, you might want to purchase a neck lanyard instead. If you're going with a neck lanyard, you REALLY need a break-away lanyard. Not just for this, but for any neck lanyard. The last thing you need is for somebody to run by and get tangled up in it, or have it snag on a fence or brush. It's a good-looking whistle, but it won't look as nice on a strangled corpse - go with a break-away.

it's ok, constructed well enough, but not as loud as I thought it would be. Does nothing to deter the neighbors dog from continuing to attack/lounge at us and others

first one I ordered didn't work... I did a return/replacement and it arrived in 2 days and works great! VERY loud.. myst wear the ear plugs.

They were not lying, it’s not false advertising, this whistle is the loudest whistle I’ve heard. I use this for training my dog, I get his immediate attention

Its loud, but not "blow your skirt up" loud. Very comparable to my old Fox 40 whistle. Will work fine for a sports feild. If you are looking for carry distance, it is pretty much inaudible past a half mile away, rather than the advertised 2 miles.

Bought it for hiking emergencies, and it is extremely loud. Definitely great for this purpose.

+++ TRES BIEN +++

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.

Ich benutzte die Pfeife beim Fahrradfahren. Ich habe festgestellt, dass sich die Leute bei einer Pfeife weniger erschrecken als bei einer Klingel. Die Lautstärke lässt sich gut dosieren, aber wehe es soll laut sein! ;-)

Excelente me gustó 👌 lo recomiendo

サイズデカいし、音は割と普通
