When setting out on any expedition, your priority should be your safety. Therefore, an emergency whistle is essential equipment for anyone involved in survival, outdoor activities, bushcraft, or trekking, for example in the mountains. The survival whistle is characterized by a very loud sound, even with a soft blow. This is thanks to its hunger-proof design, which ensures that even a weakened person can be quickly located by a rescue team, and the whistle itself will function flawlessly even in extremely low temperatures.
