Poor man's metal detector

摘要

Imagine a pleasant stroll on the beach with your trusty old metal detector, when suddenly it gives off a loud tone. After digging for a few minutes you stumble upon a ceramic pot filled to the rim with antique coins and jewellery... Eternal fame and great wealth lie ahead of you (after the government has taken its fair share...)! Admittedly, these strokes of good fortune do no happen very often, but it's still the dream of any treasure hunter. Bu then, once or twice a year there's a short article in the paper about some lucky guy who finds a medieval or Roman treasure on a field or in his back yard. Are you the next one?
