If you are lost in the woods, forest, rainforest, etc. you will need a signaling device. There are many signaling devices, including automatic signal devices, manual signal devices, and short duration signal devices.

Automatic signal devices are devices that send a signal which another one picks up and tells it where the person is, that he needs help, and stuff like that. There are Electronic Position Indicating Radio Beacon, or for short, EPIRBs.

Manual signal devices are things like signal mirrors, whistles, flashlights, signal fires, flags, and laser flares. Signal mirrors are my favorite and are great during the daytime. Their reflection from the sun can be seen 50 miles away! That is farther than a whistle could be heard! During the nighttime, laser flares are great.

Short Duration signal devices are something like flares and smoke signals. They don’t last long but they are also great signal devices. They are not good during windy or rainy days, so I prefer getting a signal mirror or a laser flare.
