Something waiting there, beneath the sand
My metal detector is with me all of the time
I'm the inspector over the mine"
In fiction, it's common to see people on beaches looking around for stuff using metal detectors.
This often carries the stereotype (in Britain at least) of someone who searches the countryside hoping to find buried treasure. This is not as silly as it sounds, since hauls of artifacts made of precious metals are occasionally found in Britain, which is what leads to this kind of behaviour in the first place. It's technically legal (and landowners have a good incentive, since they're entitled to a share of whatever's found on their land) and there are even specific laws for finding buried treasure note , however for obvious reasons it greatly annoys actual historians and archaeologists, who'd rather see the sites properly excavated rather than plundered.
Frequently they'll also find unexploded bombs or artillery shells left over from one of the World Wars, sometimes to their regret.
Note, that in Canada, the long-running TV series, Beachcombers has the starring character, Nick, in an entirely different version of this activity. Namely, it is professional lumber salvaging using boats to haul lost logs into the water for towing to timber companies looking to recover their lost materials.
