The card is made from clear plastic and comes with a Tyvek protection sleeve. It features map rules and UTM corners for the most common map scales found in the USA. It also features a compass rose with 22.5 degree increments, a list of ground to air signals, and other useful survival related information.
The best thing about the ESEE Navigation/Survival Card is the form factor. It is business card sized which makes it perfect for storing in a wallet or small E&E/Survival kit. It wouldn’t be your first choice on an orienteering course but its convenient size makes it more likely that you will have it when you really need it. This card, coupled with a button compass or small baseplate compass would make a somewhat imprecise, but very usable combination.
This card, like all other great tools, is simple and versatile. It also happens to be very inexpensive. Check it out at the ESEE website.
