Illegal Archaeologists 非法的考古學家

For many, it's a gentle hobby 嗜好 involving fresh air, patience, and perhaps finding the odd coin left from times gone by 過去的日子.

Indeed, the report accepts the vast majority of metal detectorists 使用金屬探測器的人, as they are known, are responsible and report their finds.

But there are a small minority who loot 掠奪 ancient sites and sell the proceeds to the highest bidder 出價人, sometimes using violence against anyone who discovers them.

According to the experts, nighthawkers 夜鷹（這里指晚上出動用金屬探測器尋寶的人） are often very organised, targeting protected sites 受保護的地帶 across the country.

In one field in Suffolk, more than 200 holes were dug, destroying not only the crops 農(nóng)作物，莊稼, but invaluable archaeological evidence 考古證據(jù) which had yet to be assessed 估值，核實 by the experts.

Responsible metal detectorists point out the authorities do not help matters by placing the location of recently reported finds on the Internet.
