FLIR ONE Thermal Imager for iPhone 5/5s
Much like night vision, thermal vision allows you to be aware of your surroundings in the dark. You can have the element of surprise by “seeing” others before they see you so you know when it is best to avoid or confront. A thermal imager is a great tool in an emergency, but it is also one that most survivalists skip due to price considerations. The FLIR one unit is a fraction of the cost of a stand alone thermal imaging device, and attaches directly to your iPhone (and you can keep that charged up if you have the hand cranked charger we talked about earlier).
