3. The material is aluminum alloy, and the surface is coated with anodic oxidation technology to achieve a durable color that does not fade, ensuring a longer service life.
The range of the survival whistle:
A whistle for survival does not necessarily have to be used in an emergency, such as to greet those in front or behind, to determine the distance, and to determine the direction of the sound source, and so on. However, there is a problem: sometimes, when climbing, one might just feel like blowing the whistle, and if one does it too often, everyone gets used to it and stops blowing when they hear others. They go on their own, and if someone twists their ankle or needs help, or if a new hiker who is far away from the group gets lost at a crossroad, it is very urgent if no one responds to the whistle because the others think nothing has happened. They are busy silently working hard, and they don't have the time to pay attention.
It's like the story of 'The Wolf Is Coming.'
