Quick Answer
Choose a whistle with a loud, high-frequency sound (above 3,000 Hz) that can be heard for at least a mile in various environments. Consider the whistle's durability, ease of use, and wind resistance. For example, a pealess whistle is a good option for wet conditions.
Selecting a Whistle for Different Environments
When choosing a whistle for your survival gear, consider the environment you’ll be in. For dense forests, a whistle with a loud, high-pitched sound is best. The Fox 40 Classic Whistle, for instance, emits a sound at 3,500 Hz, making it audible over long distances in wooded areas.
Choosing a Wind-Resistant Whistle
In windy conditions, a whistle with a narrow exit point is more effective at producing a clear sound. The pealess whistle, such as the pealess whistle from Fox 40, achieves this by using a small, narrow hole to expel air. This design allows for better airflow, making the whistle audible even in strong gusts.
Additional Features to Consider
When selecting a survival whistle, consider the material it’s made from. A whistle made from durable materials like plastic or metal can withstand harsh conditions. Additionally, a whistle with a safety feature, such as a locking mechanism, can prevent accidental activation. Consider a whistle with a breakaway cord or clip for easy attachment to your gear.
