HyperWhistle Review: Hands-on Testing – Survival Cache

Whistles are one of those gear items that does not get discussed much. It may not be as cool as a knife, or as fun as a tool for starting fires. But over the years I have come around to the importance of having such a simple tool in my pack. 

Whistles are lightweight, compact, and can be carried from on keychain, lanyard, or stuffed in a pocket. Their value comes from its ability to produce a very loud, distinctive sound while expending little effort. Whistles can be used to signal for help from long distances, used as a communication device between members in a group, and to scare off wildlife. 

In this article, I will be trying out the HyperWhistle. I have known about this product for some time and was reluctant in purchasing it as I figured it was just another whistle. Well, it is not just another whistle and to find out why let’s get into the review by first seeing what the whistle has to offer. 

HyperWhistle Review

Style 

The first thing to notice is that this whistle does not look like other whistles. Most whistles are flat and small in appearance, especially around the mouthpiece. The HyperWhistle’s mouthpiece is quite large and round. Its body is also quite large and features a tri-frequency design.

Material

This whistle is made from Anti-microbial composite and constructed for all weather conditions. This material also makes the whistle naturally buoyant.

Sound

Capable of 142dB, the HyperWhistle is advertised as the loudest whistle in the world. It can be heard up to 2 miles away and even works underwater.

What’s Included

When you purchase this it comes with one HyperWhistle, a lanyard with an easily detachable plastic clip, and a pair of soft ear protectors. 

Color

The HyperWhistle does come in two available color options. Black or orange. 

Testing 

The first thing that I noticed after opening the package was that the whistle came with a pair of ear protectors. The company is either covering their bases in helping to prevent hearing loss or they are trying to tell me that this whistle is very loud. Probably both and I should have taken the hint at this whistle’s capability, but I didn’t. 

After removing the contents of the package I quickly attached the black lanyard to the whistle and took it out to my garage to try it out. Mistake number one. I placed my lips on the mouthpiece, sucked in a lungful of air, and blew. 

The loud, high pitched sound that was produced actually made my face scrunch up and caused me to drop the whistle. Luckily, it was attached to the lanyard which was hung around my neck. Okay, so don’t use whistles in enclosed spaces. Duh, you knew that but moving on. 

Next, I moved out into the wide-open space of my backyard. Thinking that this was going to drastically reduce the sound I once again ignored wearing ear protection. Mistake number two. I once again placed my lips on the mouthpiece, sucked in a lungful of air, and blew. 

While the sound that was produced was not nearly as cringe-worthy as it was in the garage, it was still piercing and loud. And I mean LOUD. Several dogs throughout the surrounding area began barking. I think they heard it as well. 

Tri-frequency Design 

The way this whistle is designed looks a bit weird when compared to other whistles. From what I can tell it is three whistles in one. There is one mouthpiece but three individual side ports where the sound comes out. Interestingly, when I blocked one or even two of these ports, the whistle still worked. Just at a more diminished capacity. 

Water Test

On the back of the packaging, it notes that the whistle is naturally buoyant. I love gear that floats because accidents happen and over the years I have dropped numerous items in the drink.
