- Your phone – call for help and get located by the phone's signal. Your phone is a modern marvel you should always carry.
- Space blanket – this reflective piece of plastic can keep you warm when things get cold, or bounce away heat when you get too hot in the sun.
- Lighter – a simple butane lighter can give you fire. This ancient element can boil water, provide warmth, signal for help and perform a host of other tasks.
- Signal mirror – on a sunny day, a mirror can flash a beam of light up to 10 miles and they are perfect for signaling aircraft.
- Compass – even if you don't know where you are, a compass can still help. By determining the cardinal directions or following a straight line, you may be able to self-rescue (rather than wandering in circles as most people do).
- Lifestraw – these cheap water filters are lightweight and small enough for your pocket, providing gallons of safe drinking water from surface sources that could be otherwise contaminated.
- First-aid kit – injury is the second most common reason for SAR callout. Carry a small first-aid kit, with bandages and dressings for trauma. Bleeding control may save a life.
- Whistle – when SAR crews are close, blowing a whistle can get them the last few hundred yards. It could also catch the attention of a passerby.
- Flashlight – a light can signal your location after dark, help you find your way and reduce fear in the darkness (especially for kids). Carry a quality, waterproof flashlight with a long battery life.
