About the Use Standards of Survival Whistle [Repost]
A survival whistle 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 here. Sometimes, when climbing a mountain, one might just feel like blowing the whistle, and if one does it too often, others may not feel anything special about it. If they hear someone else blowing the whistle, they may not feel like blowing it themselves. They may continue on their own, and in such a situation, if someone's ankle turns or they need 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 blowing. Because the others might think nothing has happened, and they are busy silently working hard, they don't have the time to pay attention to it. It's like the story of "The Wolf Came."
Symbol Explanation: ● Short sound (within one second); ■■■ Long sound (over 3 seconds); The whistle sound within the instruction is 2-3 seconds, and the interval between instructions is over 30 seconds (e.g., to repeat the instruction, you need to wait over 30 seconds).
Communication (T): ■■■ (a long sound) is used for voice communication among the team to determine the direction of each other's whistle signals. After receiving a whistle command, it is used to indicate that the command has been received (similar to the shout "Hey~~~~~").
Assembly (U): ● ● ■■■ (two short and one long) Move towards the direction of the whistle call (similar to the shout "Assembly!!!!")
Advance (V): ● ■■■ (one short and one long) Rest time: represent the entire team's departure. During movement: represent accelerating forward (similar to shouting "Charge!!!")
Front Team Wait (W): ● ■■■ ■■■ (One short two long) Used when the front team needs to wait for the rear team due to the long distance of the march (similar to the shout "Please wait~~~ wait~~~~")
SOS: ● ● ● (Three short beeps) When in need of help, send out this signal. The receiver responds with a communication tone (T) to indicate they will come to assist (similar to shouting 'Help! Help! Help!')
SOS: ● ● ● ■■■ ■■■ ■■■ ● ● ● (Three short, three long, three short) This is the international SOS code, please remember it.
