Can you use multiple whistles for different signaling needs?

Choosing Multiple Whistles

Selecting the right whistles is crucial. Opt for a combination of loud and high-pitched whistles that can be heard over various distances and in different environments. For example, a pea-less whistle and a pea whistle can serve as a dual signaling system.

Signaling Techniques

Develop a distinct sequence for each whistle to avoid confusion. For instance, three short blasts on the pea whistle could signal that you need assistance, while six short blasts on the pea-less whistle indicate that you’re in a life-threatening situation. Use at least 10 seconds between each sequence to allow for clear interpretation.
