If you want to have an ideal outdoor trip, don't forget to prepare carefully before departure Don't forget to check if you have brought your whistle before departure Guidelines for the use of survival sentries [repost] A survival whistle doesn't necessarily have to be used in times of danger, such as saying hello to those in front or behind, determining how far apart they are, determining the direction of the other person's voice source, and so on..... However, there is a problem here, which is that sometimes when climbing a mountain, everyone just starts blowing their whistle. After blowing too much, everyone doesn't feel anything anymore, and they don't want to hear others blowing anymore. They just go their own way. At this time, if someone's foot twists, or if they need help somewhere, or if a new donkey that has been pulled far in the middle encounters a crossroads and doesn't know how to go, it is very urgent that no one responds when blowing the whistle, because others think nothing has happened, and they are busy silently grinding and don't have much time to deal with it, just like a wolf coming Symbol description: ● Short note (within one second); ■■■ Long notes (over 3 seconds); The interval between whistle sounds within instructions is 2-3 seconds, and the interval between instructions is more than 30 seconds (for example, repeating instructions requires an interval of more than 30 seconds) Communication (T): ■■■ (one long tone) is used for team voice communication to determine the direction of the whistle between each other.
