How to send distress signal in the field
When travelers need help in the wild, they often need to use a variety of different ways to send distress signals, so that they can be found earlier.
(1) The internationally used mountain distress signal is whistle or light, which rings or flashes 6 times every minute. After an interval of one minute, repeat the same signal.
(2) If there are matches and firewood, you can start a fire and add some wet branches and leaves or grass to make it smoke heavily.
(3) If you wear colorful clothes, you should also choose bright hats.
(4) Use branches, stones or clothes to build SOS or other words for help on the open space. Each word should be at least 6 meters long. If you are in the snow, step on the words.
(5) Use the brightest and broadest clothes as flags and wave them constantly.
(6) When you see the helicopter approaching the mountain for rescue, you can light a smoke signal bomb (if any), or light a fire nearby to raise thick smoke, so that the rescuer can know the wind direction, which can help the rescuer accurately grasp the parking position.
