Having the best whistles is essential for outdoor and survival uses. They are used for identification purposes and as a safety device to help rescuers locate you while lost in the woods or on water.  Whistles produce a very sharp sound that can be heard over long distances, even in noisy environments.

An outdoor whistle is a device to produce sound waves by the force of air exhaled through the lips. There are various types of whistles in the market, most commonly used on boats as short-range communication devices and for signaling purposes in case of distress. 

Many people do not own survival whistles, though they are small in size and easy to carry. But even if you aren't a prepper, you should always have a whistle with you because it could save your life one day. Most of us use mobile phones nowadays, but their chances of getting a signal in emergency cases are very less. 

Hence, it would help if you got the following whistles.

How To Choose The Best Whistle For Survival And Outdoors

A whistle is possibly one of the best and easiest ways to signal for help. However, most people don't know what type of whistle to choose from or how a whistle should be used in an emergency. Knowing which kind of whistle to choose (and why) can make all the difference between getting rescued and being stuck out there longer than you had hoped.

In choosing a whistle for outdoor, survival, and emergency purposes, the following considerations should be taken into account.


This is the most crucial consideration when choosing a whistle. The louder the whistle, the more likely it will be heard over background noises such as traffic, storms, etc. Whistles are generally rated by their decibels or DB scale—a measurement of loudness. A loud whistle can help alert rescuers that you need help or indicate that you are up and well.

However, it's important to know that decibel ratings for whistles are not the same as those for other instruments. A whistle can only produce sound between a range of frequencies, but a microphone or digital recording device can pick up sounds over a wide range of frequencies. For this reason, peak decibel measurements may not be an accurate indication of a whistle's effectiveness.

To determine which is the loudest, you need to perform a comparative test in your own environment. You can do this by going outside on a clear day and signaling for help at various distances from your home or workplace. To ensure that you are getting a true reading, you must test the signal of each whistle in an environment that is free from other ambient noise.

Another thing to keep in mind when looking at loudness scales of whistles is that the sound level can easily vary depending on the position of your mouth and lips around the mouthpiece. The closer your lips are to it, the higher the pitch of the sound.

Water Resistance

An excellent outdoor survival whistle should be waterproof and windproof. This is important because if you are in a situation where you need to use your whistle, it's likely that it will also be raining or snowing—or both! You don't want to find yourself standing there, unable to signal for help, simply because your whistle isn't working.


The design of the whistle is also essential. A bright color can help to make it stand out and be more easily visible. A larger, easier-to-blow hole means a louder sound could be made.

For outdoor use, the most appropriate designs are either pea or pealess.

  • A pea whistle uses a ball of whistling metal that is blown through a small hole. These are relatively easy to blow and produce a loud sound. However, many find them unreliable because of the moving parts. Moreover, they aren't that hygienic.
  • A pealess whistle uses a smaller chamber than the main body. You have to pass air over the special ridges on the whistle's surface to produce the sound. This is often considered to be more hygienic than a pea whistle. While it is true that they aren't as loud as pea whistles, they can still get the job done, especially in producing audible signals. Their stability is also impressive because of the absence of moving parts.


You shouldn't expect a cheap whistle to last you very long. Invest in something that will stand the test of time! Make sure it's resilient, made from tough material, and well-constructed.

The most common material used in making outdoor survival whistles is either plastic or aluminum. The latter can be more durable, especially when it's coated. For an even more resilient whistle, consider buying something made from ABS plastic or brass.

Comfort And Grip

There are survival whistles that have a cushion at the bottom end for comfort and grip; others come with thin wires attached to their sides so you can hook them onto your clothing, backpack, or keychain.

For convenience, it's often better to go for a whistle that has a lanyard hole at the bottom end so you can quickly hook it onto your clothing or other items. It will also be ideal if the length of this hole is adjustable so you can make sure it will fit all your needs.

In Summary

You must get the best whistles for outdoor and survival use. You'll never know when a disaster will strike. Hence, it would really be best if you can prepare for them. These whistles help rescuers and helpers find your location in times of emergencies. The distress signals you send through these whistles would one day save your life.
