You do not look for Bio agents in the ground with a metal detector.

Nuke agents, stored in lead, would be detected with a metal detector.

That would send a realy loud alert to the person operating the detector. (I know because a 12 pack of beer cans burried on the beach in Corpus Christi makes you think that you have found gold).

The person operating the detector, getting a really loud alert from his detector, would not flag and walk forward. It could be a mine.

While I am typing this, while watching FNC, it looks as if they are throwing swords on a tarp in the back yard.

Did you or anyone else see that?

Swords? Probably probes which hit on solid objects buried in the earth.
