After a thousand years, a foolproof compass! It's the Model 8099 Eclipse from Brunton, which dispenses with the spinning needle in favor of two magnetic circles that align and show you the way. Can't remember what declination is, or how to take a bearing? Its shockproof case stores three indestructible data cards that tell you all that stuff. It has a clear pull-out base plate that aligns with a map, and many more features as well. The price is $79.95, pretty cheap insurance for when your GPS is addled.
