John McCann, owner of Survival Resources in Hyde Park, New York, where he teaches survival courses to adventurers of all ages, has developed an inventive survival kit small enough to fit in your pocket.

These 35 items, contained in McCann's survival kit in a tin, will help you survive outdoors should an unexpected emergency arise, whether you're going for a walk outside, or camping out for a few days.


Fire and Light
Spark-Lite Firestarter
One-handed fire-starter used to produce sparks to light the Tinder-Quick Fire Tabs listed below.

4 Tinder-Quick Fire Tabs
Waterproof, wax-impregnated cotton tinder, which can be ignited with a spark from the Spark-Lite Firestarter. They burn approximately 2 to 3 minutes, allowing you time to establish a fire using other available tinder and kindling.

4 Wind/Waterproof Matches
These matches are an additional means by which to initiate a fire.

Signaling
Cylinder Whistle
A small signal whistle can be used to identify your location to rescuers. It takes less energy to blow a whistle (3 toots are the international distress signal) than it takes to yell.

Mini Signal Mirror
A Lexan polycarbonate mirror can be used to signal rescuers and can be seen up to 20 miles.

Navigation
20-millimeter Button Compass
A liquid damped compass for navigating back to civilization.

Water and Food
Water Bag
Made from a Reynolds Oven Bag, it is marked with a 1 quart line in order to measure the appropriate amount of water for use with a water purification tablet. It can then be used to carry water while on the move.

4 Water Purification Tablets
The Chlorine Dioxide-based tablets provide protection from bacteria, viruses, and cysts such as Cryptosporidium and Giardia.

Fishing Tackle
Enclosed in a small plastic vial, it can be used to catch fish for sustenance. It includes two No. 8 hooks, four No. 10 hooks, one No. 14 snap swivel, and six BB split shots.

50-foot Braided Fishing Line
Used with the above tackle to fish, it can also be used for sewing.
