List of Great Survival Gear

Here is a good list of survival gear posted by Filipino Mountaineers Society:

Other gear essential are somewhat optional in there own ways but I personally like to carry them during my adventure to maximize my chance to survive or to get out alive. 

1.) Two-Way Radio is one of the most reliable means of communication and with the right knowledge on how to use it can definitely secure your safety, especially when you know the right frequency.

2.) Portable Phone, Extra Battery & Power Bank are a sure win in terms of calling for rescue as long as you have good network coverage.

3.) Torch or Head Light and Extra Battery can definitely make a big difference specially when trying to figure out things in the dark.

4.) Writing Pad, Pencil & Pen - Not only you can log all the proceedings of your event but it's another way of keeping yourself sane...trust me on this one because history has its potential means of repeating by itself and others may learn immensely from other adventurer's account.

5.) Clothing - It is wise to wear a layer of clothes according to the exact weather conditions. A great deal of knowledge on conduction,  convection and precipitation could save you from the natural elements in the great outdoors.

6.) Ration - As a responsible and organized adventurist, you should know the extended period of time of a certain event so that you can easily recharge and refuel without consuming your emergency ration.

7.) Identification - carrying all means of identifying you in case something goes wrong can be useful. I personally carry a piece of paper with my Name, Address and who to contact in case of Emergency. (Be sure to add the things that you might be allergic into so that it can be prevented by your rescuers...example: penicilline and so on...)

8.) First Aid Kit - Bandaid (Big & Small), Gauge, Batadine, Wet Wipes, Aspirin Tablets, Inflammatory Tablets, Water Treatment Tablets, Diarrhea Tablets and Duck Tape Role are some of the things inside my first aid kit.
