As the product details describe, this map has one side that features a view of Patagonia, and the other side has a close up of Tierra Del Fuego.
The side with Tierra Del Fuego shows excellent detail, so if you are going there, this is a fine map to have.
However, the detail on the Patagonia side is pathetic. I have the ITM South American Continent map, and it shows almost as much detail of Patagonia; it is also made of a higher quality paper; and to top it off, I think the large South America map is also about the same price as this map!
It's a bit frustrating that the most detailed area of the map does not include some of Patagonia's most visited areas, like Torres Del Paine, or Mt. Fitz Roy.
If you are not going to spend much time in Tierra Del Fuego, or if you are traveling more in depth in other areas of Patagonia, like Torres Del Paine or anything to the north of that, this map isn't much use.
