1st time metal detecting - can rocks set off detectors?

[Kreebo]

Today was my first day metal detecting and found this metallic rock. I was wondering what rocks set it off. Just trying to see if I can narrow down the list to identify this find. I’m in the middle TN region.

That could be just a glob of melted steel.

Yes, electricly conductive rocks can trigger a detector. They are called "hot rocks".

They are -thank good- rare in my little part of the world, its mostly alluvial soil here. I do have some lying around somewhere, though (mostly green = nice grade copper ore).

Around older homes you ll have to fight also coke/coal which kick the detector off (though these tend to have a unique signature, allowing to walk over them).

The stuff in question looks like slowtakon said, rather more than something melted (iron, alu) or slag than a natural rock.


And welcome to T-net!

Welcome to TreasureNet. Looks like melted metal of some sort.

I'm guessing an aluminum wad, and yes rocks can set off metal detectors. With some usage, you'll be able to tell the difference.
