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

Purchased for my Grandson to help keep him safe in the woods. This is the very best product I've ever encountered, to be heard if you need to be located in a distressed situation, or maybe make a bear or cougar have second thoughts. This whistle, a boat horn, with bear spray, and most importantly a Byrna.The warning to not use inside, as well as hearing protection advised is spot on serious!

Item as described!

Works great, bought it in case I need to use in an emergency while hiking to call for help, fortunately I have not used it yet, but it whisples pretty far.

The media could not be loaded. I bought this for a wilderness bag and I wanted a whistle that was as loud as possible. The description claimed that this whistle holds the Guiness book of world records title as the loudest whistle at 134 decibels. I tested it beside 3 other whistles I have 1 cheap "survival" whistle, and 2 "coach style" metal whistles. I used my Apple Watch's Noise app to determine the decibels each one produced. I did it multiple times, to the point where I felt like I was in the hospital taking a respiratory test! Results: 1) "Survival" Whistle = 107 db, 2) Orange Coach Whistle = 118 db, 3) Green Coach Whistle = 119db, and finally the 4) HyperWhistle = 120 db. The HyperWhistle is bulkier than the coach whistles by maybe double. The size didn't bother me. What did bother me was that it wasn't significantly louder than the standard coach whistles. I am not an audio expert, at all. I wonder if maybe the HyperWhistle sound carries further than the other whistle's sounds? Maybe I'm being overy optimistic? Anyway, watch my video and you'll see the DB results on my watch and can hear the sound each whistle makes. I like the HyperWhistle, but I don't think I'd buy it again because it's just not that much louder.

This product is an awesome one, I will buy it for my people. Thanks

The included lanyard cannot be attached to the whistle. There's a clip on it but no place to clip the whistle on so now it's off to a local store to buy another whistle. The whistle is fairly loud but I don't have room in my pockets for it.

Nice

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
