Answer: Metal Detectors
Explanation: Metal detectors are inexpensive and easy to use equipment used to discover relics of the past. While it is useful in archaeology as a tool that discovers objects from the past quite easily, it is also a threat to archaeology. Some hobbyists and looters who come across archaeological finds which may be important to understanding past civilizations or a different era do not report these finds. Even worse, some looters knowingly infringe on archaeological sites and are aided by the metal detectors.
