1. Dual-frequency design. Different-sized sound chambers on the left and right generate high and low frequencies simultaneously, ensuring penetration in various environments and conditions.

2. Anti-slip design for the whistle mouthpiece. You don’t need to hold it with your hand; you can also hold it with your mouth without worrying about the airflow blowing the whistle away.

3. It is easy to produce sound. When trying to survive or asking for help, focus on conserving energy; a good survival whistle can produce sound easily. Some products on the market may make a loud sound, but it is not easy to produce sound.

4. Integrated design, robust and reliable.
