Other ways for sos to seek help

fire

In the dark, fire is the most effective signal means. Light three fires and let them form a triangle (international distress signal) or a straight line. Each fire is about 25 yards (23 meters) apart.

As long as time and circumstances permit, light them as soon as possible, and be careful not to put them out until you need them. If you are alone, it may be a little difficult to keep three fires, so protect one fire.

smoke

Smoke can be used to attract attention during the day. The international distress signal is three columns of smoke. You should try to distinguish the color of the smoke from the surrounding background: if the background is light, use black smoke and vice versa. If you add some green leaves, moss or water to the fire, the smoke will turn white.

If you add some rubber, rags soaked in oil, etc. On the fire, the smoke will be black. In desert areas, smoke can't rise, and it always lingers on the ground, but in empty desert areas, pilots can still see it.

Using smoke as a signal is usually only suitable for relatively sunny days. Strong winds, rain and snow will disperse the smoke and reduce the possibility of your being found.

Smoke bomb. If you have smoke bombs, you can use them like flames. Grenade must be kept dry, effective when necessary, and be careful not to ignite the surrounding plants when using it.
