When you are traveling or exploring in the wilderness, in addition to those professional equipment, it is also recommended that you bring a small wilderness first aid kit (or you can also call it "wilderness survival kit"). Don't look at it small, in critical moments may play a big role.
Box:
It is best to choose an aluminum or stainless steel lunch box (preferably with a handle). This is because the lunchbox itself can be useful for heating, carrying water or melting snow. Plastic boxes, while lightweight, cannot be heated, and their use is limited. Also, the metal lid of the lunchbox can be used as a reflector to signal for help in a pinch.
Tool knife:
A multi-functional utility knife is absolutely necessary in the field. Although it is not necessary to use a jungle fighting knife similar to the one used by Rambo, a Swiss Army knife is essential. It integrates the usual knife, driver, and scissors, but also a saw, screwdriver, file, and even a magnifying glass!
Needle and thread bag:
Both in the era of the Red Army's Long March and in modern armies, the needle and thread bag has always been a field essential for the military. Of course, the function of the modern needle and thread bag is not only the original simple sewing, the needle can not only pick thorns, but also in some cases can be bent into a fish hook, to improve food, and even save lives (of course, your needle and thread bag must be equipped with at least two fishing line).
Matches:
In the wild, fire is almost everything. It's important to bring wind and waterproof matches, but if you can't buy such matches, you can DIY some yourself. The method is simple: melt a candle and apply it evenly to regular matches, and when you use them, just get rid of the wax on the match head. In order to utilize the "strong" wind and waterproof function of our DIY matches, you can put them in an empty film box. You can't forget the phosphorus skin (which is used to wipe the matches), otherwise our DIY efforts will be in vain.
Candles:
A small candle is definitely useful in the wild. The flashlights, headlamps, and other modern lighting devices you carry become useless as the batteries run out. This time the candle will show its "hero". In addition to lighting, candles can be used to keep warm (but don't mistake your fingers for potatoes) and to start a fire. If you cut off the bottom of a mineral water bottle and make it into a lampshade, you have a windproof lamp for the field, which has enough "power" to work more efficiently.
Survival whistle:
It's just a whistle, but in the wild, it's more than just a black whistle you blow on the field. Now it can save your life. When you're in distress, you can use your whistle to lure rescue or scare away some small beasts (though not squeaking is the best option if it's a tiger, bear, or other fierce beast).
Aluminum film:
This is a 2x2 meter film coated with aluminum, available in gold and silver. It not only protects against wind and rain, but can also be stretched up to make a pergola to prevent direct sunlight. In cold areas, you can wrap yourself in it to keep your body temperature up. The biggest role of aluminum film is that it can reflect light, so that rescuers can find you in time. Normally, you can also spread it on the ground and use it as a floor mat.
North compass:
Even if you bring a GPS and your watch comes with an electronic compass, some primitive north compass is still essential. In the wild, no one can guarantee that the advanced equipment will not go wrong, and at this time, a small compass can help you find your way home.
Medical tape:
Don't underestimate any of these little gadgets, it's the fastest fixer. It's useful when your outerwear is scratched and your tent is blown apart. Although its basic function is to attach saran wrap, use your imagination a little and you'll find it can be of far greater use.
Dovetail Clip:
Although it's an ordinary office supply, it can be useful in many unexpected situations in the field. It has been used to clip broken backpack straps, pants with open threads, and shoes with the soles off Although we don't really want it to work, it might be useful to have a few extra on hand.
Pencil:
What kind of pen do you use when you want to write something in the wilderness? Parker? No, the most expensive may not be the best. The harsh environment in the wild makes pencil our best and only choice. It is recommended that you choose a pencil of 2B or higher.
Paper:
Preferably Post-it notes, preferably white.
Several bottles:
Put salt, fruit candy, vitamin C. These unassuming foodstuffs can be life-saving medicine in a crisis.
Finally, it is recommended that you put a waterproof Ziploc bag on the outside of the first aid box (a household refrigerator sealing plastic bag will do, and if you have a professional waterproof bag, it's more of a good thing).
