The ESEE survival / navigation notebook with cards is a great tool when reading a map in the wild. The notebook contains plastic, credit card-shaped cards with essential survival and map-reading information. From tricks to better estimate the width of a river to map and compass tools. These cards are attached to the notebook made from waterproof paper with the help of plastic screw. You can easily loosen this screw by hand after which you can also use the cards individually.
The paper is waterproof and made by the famous Rite in the Rain. This means that writing instruments with water-based inks have little or no effect on the paper. That is why we recommend using a pencil or ballpoint pen. A pencil will never be without ink. It won't dry out and it is easy to 'sharpen' with your survival knife. Perfect for this paper and survival situations!
