If you’re lost in the wilderness or facing down an attacker being able to signal for help is critical. One of the best ways to do this is using an emergency whistle. Unfortunately not all whistles are created equal and something that a coach or referee might love probably won’t serve nearly as well for a signalling whistle. To help you out we’ve reviewed some of the top whistles available today and put together a basic buying guide so you can find the best emergency whistle for your needs.

Storm Alert Whistle

Storm Survival Whistle All Weather

The Storm Alert whistle is marketed as the world’s loudest whistle and we can attest that it’s really, really loud. It’s been reliably measured at 130+ decibels when at full blast. It’s made from sturdy blaze orange plastic for strength and high visibility using a dual chamber design.

This makes it louder and easier to pick out than other whistles but that’s just the beginning of the Storm Alert’s features. It was built from the ground up with sailors, boaters, and divers in mind. Its design allows it to function perfectly even when submerged underwater.

The Storm Alert is so good at what it does that the US Military as well as dozens of law enforcement and maritime agencies issue them as a standard tool.

It’s definitely on the large side for an emergency whistle but considering its feature set we can forgive this. If you’re looking for a signaling whistle for your boat or dive kit the Storm Alert should be your first choice.

Gerber Bear Grylls Ferro Rod with Emergency Whistle

Bear Grylls is known around the world as an adventurer and survivalist. His partnership with Gerber has created some innovative and downright useful gear. The Bear Grylls fire starter and whistle combo is one of these tools.

It combines a nice ferrocerium fire starter in a tinder containing tube with a whistle. The whistle is built into the pull tab of the lanyard and is extremely small and lightweight. We tried it out and found it to be a bit quieter than stand alone whistles but still easy to pick out over a large distance.

SOG Flint Aluminum Survival Whistle

SOG Survival Safety Whistle

SOG’s mission is to produce the most rugged and mission ready outdoor and survival gear on the planet. Their Flint Survival and Self-Defense tool does a great job embodying this ethos. It combines a fire starter rod, pea-less safety whistle, and carbide glass breaker into a package about the size and weight of a pen.

The body is made from anodized aluminum and is just over 4 inches long when closed. To use the various tools you unscrew the o-ring sealed compartments and rearrange them. The fire starter produces a large spray of sparks and includes a large enough compartment to store some dry tinder.

The whistle is located at the top of the Flint near the attached lanyard ring. It’s very small but still loud enough to be heard over a very long distance. On the other end of the Flint is the carbide glass breaker/self-defense tool. Sadly we didn’t get a chance to gleefully shatter glass with it but we have no doubt that it would perform admirably.

If you’re looking for an ultra compact multi purpose survival tool the SOG Flint Survival Whistle and Fire Starter is an excellent choice.

Buyer’s Guide for Best Emergency Whistle

Because of their simplicity you don’t have to worry about too many issues when picking between emergency whistles. Price, materials used, and the style of the whistle are the main ones plus a few other factors for very specialized uses.

Price

An emergency whistle definitely won’t break the bank. You can get high-quality models for under $10 and will find it hard to spend more than about $30 on one.

Even high-end whistles made from materials like titanium are quite affordable and strong enough to last a lifetime. The sole exception to this is buying an emergency whistle as part of a multi tool. These can rapidly get more expensive than just a whistle itself.

Pea or Pea-Less

If you’ve ever used a coach’s whistle you probably felt something rattling around inside there. Early generation whistles used an actual pea, hence the pea/pea-less naming system. The purpose of the pea was to break up the flow of air and create multiple tones and intensities of sound.

This makes it stand out more against background noises. Pea-less whistles have a more even tone and are generally a little louder overall. The biggest difference between the two is their size and shape.

Pea whistles have a larger sound chamber and are a bit bulkier than pea-less versions. The pea-less whistles are longer, thinner, and usually a little sleeker looking in design. Most of the newest emergency and survival whistles will be pea-less.

Another major difference is in reliability. A pea whistle is much more susceptible to drops, dents, and water damage than a pea-less model. You have to deform the shape of the mouthpiece pretty badly to damage a pea-less whistle.

How Loud It Is

Emergency whistles need to be loud. Piercingly so. Just about every whistle manufacturer claims to have the loudest whistle in the world. Figuring out which one is actually telling the truth is a bit more difficult.

Sound intensity is measured on the decibel scale. Most whistles fall somewhere between 100 and 145 decibels. To put this in perspective a rock concert at full blast is about 125 decibels. Anything above that begins to cause physical pain to hear.

Many manufacturers unfortunately don’t list their decibel rating for comparison purposes but you can often find the information on other sites.

The factors that affect the sound of a whistle are generally resonators and sound chambers. Up to a point the more sound chambers and resonators present in a whistle will result in a louder sound.

Portability

The vast majority of emergency whistles are extremely easy to carry. To function properly they need to be below a certain size. Their overall design, a hollow piece of metal or plastic, also helps make them incredibly light.

The most important point in whistle portability is how you want to carry it. Most come with lanyards or other attachments. Those built into multi tools often fit snugly into a slot. Wilderness whistles can generally be less readily accessible than urban survival ones. They need to be ready at an instant’s notice while wilderness whistles have different priorities.

Durability

Emergency whistles need to be quite durable to work properly. They’re only useful in trying and potentially damaging situations. The way whistles work, even apparently superficial damage to certain surfaces can throw off their ability to produce sound.

Look for durable materials like polycarbonate, stainless steel, anodized aluminum, and titanium. These stand up to drops and can be stuffed into the bottom of a pack and forgotten until needed.

Is It a Multi Tool

By themselves whistles aren’t really multi tools. They fulfill several roles but most are closely related. Many full multi tools do include whistles as part of their tool loadout. If you’re looking for a multi tool whistle we recommend you check out one of these.

Water Resistance

Depending on how you plan to use your whistle true water resistance may not be much of an issue. All whistles can stand up to rain and splashes without blinking. When fully submerged though a non water resistant whistle will stop working until it dries out.

For boating, diving, or other aquatic activities you absolutely need a waterproof or at least water resistant whistle. These have specially designed cases and mechanisms that allow them to work after being submerged. Some specialty diving whistles will even sound underwater if you can believe it.

Why Carry a Whistle

A whistle is one of the most useful emergency tools you can carry and most people don’t even know it. It provides a lot of value in urban or wilderness situations and can be used for everything from signaling to defense.

Signaling – The most obvious use for an emergency whistle is as a signaling device. Whistles produce a piercing tone that can carry for miles. If you’re trapped in the wilderness or in an urban survival situation such as an earthquake this gives you a much greater chance of being found.

Self Defense – If you grew up in the 80’s or 90’s you’re no doubt familiar with rape whistles. These are manual or electronic tools that make a deafening whistling sound when triggered. They draw attention to you and can actually damage an attackers hearing if close enough.

Final Thoughts

Emergency whistles are inexpensive, easy to use, and extremely useful in a survival situation. Picking the best emergency whistle really comes down to where and how you plan to use it.

If you’re planning on going boating you absolutely need a fully waterproofed maritime whistle. For urban and self-defense needs ease of access and portability are king. In the backcountry is where volume and reliability become the key factors.

You need your whistle to be heard over potentially miles of empty country in the event of an emergency.

As long as you keep your specific needs in mind it’s easy to find a high-quality whistle for a very affordable price.
