如今，熟练的金属探测员与考古学家和文物保护者一道工作，在战地考古中扮演着十分重要的角色，文物保护者负责精确地记录发现器物的位置，并进行“封装、贴标以及作标记”。
Today, skilled metal detectors, working with archaeologists and heritage preservers, play a very important role in field archaeology. Cultural relics preservers are responsible for accurately recording the locations of objects found and "encapsulating, labeling and marking".
换句话说，每件古器物都被封装起来，贴上标签，放在挖它出来时所开凿的洞里，以便在将其移走用于以后研究之前查明它的精确位置并绘制成地图。
In other words, each artifact is encapsulated, labeled and placed in a hole dug when it is dug out, so that it can be located accurately and mapped before it can be removed for future research.
