What is a green whistle?

A green whistle is a type of emergency whistle that is commonly used by hikers, campers, and other outdoor enthusiasts for signaling for help in case of an emergency. Green whistles are typically made of plastic or metal and have a loud, high-pitched sound that can be heard from a long distance.

Green whistles are often brightly colored, such as neon green, to make them easily visible in outdoor settings. Some green whistles also come with a lanyard or clip for easy attachment to clothing or gear.

In addition to outdoor activities, green whistles are also used by lifeguards, first responders, and in emergency survival kits. They are a simple and effective tool for attracting attention and getting help in critical situations.
