Waterproof map case

For some time I have been looking for something to store my books and maps in while observing. The problem is, books and maps always get dirty and wet when used outside. Yesterday I got a waterproof map case (A3) and I had a chance to test it last night. It works perfectly. The map case is made of heavy transparent PVC (poly vinyl chloride) and is 100% waterproof. After inserting the books into the case, you can close the case with two aluminum rails that are held together with 4 screws. In the A2 map case you can easily get two books like the Rukl Moon Atlas (See image below).

I used the map case for 4 hours last night at the telescope. I only had to open the case once to turn a page. The humidity was 80%, but when I got indoors this morning, I immediately checked the books and they where completely dry. In time I will write a more detailed report in my equipment section with some more images, but for now I can tell you that I’m very pleased with this waterproof map case.
