Is there anything special required for a compass for use in Peru? I seem to recall something about the needle dipping, but I'm not sure if Peru is "south enough".
Anyone got a url for declination info there?
My nephew is trekking there soon and I was hoping to get him something from EMS rather than the internet before he leaves.
