Debate: Should we use metal detectors on known burial sites?

I was at a dig near a Native American mound in Ohio back in October when a volunteer pulled out a metal detector and started scanning the edges without asking first. The lead archaeologist shut it down fast, saying it could disturb grave goods or human remains. But another crew member argued we might miss small artifacts that tell us about trade routes. I get both sides, but where is the line between being careful and missing data? Has anyone else been in a similar spot where a tool caused this kind of split in your team?

That 2018 Cahokia thing reminds me of when I accidentally set off a metal detector in a museum gift shop once, thought I'd discovered a lost artifact but it was just my belt buckle. I get the worry about disturbing stuff, but if we're going to use metal detectors on known burial sites maybe we should just stick a sign on them that says "please don't scan the dead, kthanks." At the end of the day, you can't ethically unring that bell once the detector finds something that changes the whole story.

The 2018 dig up at the Cahokia Mounds had the same argument when someone wanted to use ground-penetrating radar. The elders on site made a good point that if you can't see it from the surface without tools, maybe it's meant to stay put. Sometimes respecting the site means accepting we won't get every piece of data.

Push back a little here, @tylermurray, but tools like ground-penetrating radar don't dig anything up, they just let us see what's already there without disturbing it at all. Isn't that actually more respectful than leaving potential knowledge buried forever without even knowing what we're missing?
