No wonder it was an Italian who discovered America.

I had to laugh when I saw a post by one of you fine UK citizens indicating 
ignorance when it came to understand how a magnetic compass works and how
to 
correct to and from magnetic and true. Can it be that most of you dear 
backwards people don't know how to navigate? Are you all over relying on 
your GPS units?

Here's a good link that will educate you and allow you to arrive at a 
destination using your compass.

I hope this helps.  And for those of you who think Columbus was a Spaniard

you're wrong. He was born in Genoa Italy and he invented the Genoa jib.
