I get a real kick out of a current Johnny Walker commercial on TV (in the US only probably not seen elsewhere). It shows an expedition to the South Pole in 1908 and how they are getting there via COMPASS! The compass would not point to the geographic south pole. It would point to the magnetic pole. These poles, of course, do not coincide. Further, on a straight line path to the geographic pole, the compass would swing terrifically. You could navigate to the pole this way, under the assumption that you knew the variation of the compass for the sledging journey. Since the 1908 journey was a pioneering expedition, how could they know the variation? Wouldn't they be trying to measure the variation? Of course, its only a 30 second commercial but there are no sextants or theodolites. The commercial does show an individual HOLDING the compass and watching the needle swing. Yup, that will get you there!!!!
