Rocks that set off metal detectors/pinpointers

[Bucket Lister]

Is there a list of rocks & minerals that will set off metal detectors?
I found such a stone today--it was infuriating!!!! 🤬

After several minutes of sifting through substrate with my pinpointer expecting to find another rusty square nail, all that was left was one stone. It doesn't set off the pinpointer like being in contact with a piece of metal, but it does set it off--like being a few inches away.

No, it's not being set off by my keys or pocket change--BT-DT. 😳

So my thing about it is just this:
....

Dude. That's not a thing. That's a manifesto! 😲

Maybe copy it to your profile so you can point to it when people say you're nuts(?) 🤪

My girlfriend and I go out adventuring every week,

That sounds a bit like us... 50 years ago. 😝

We engage in foraging, scavenging, wildlife photography, relic hunting and other exploratory pursuits.

Yeah... exploratory pursuits... Is that what you kids call it today? 🤣

There's more I could say regarding why I go about it in that way but it boils down to logistics honestly.

No, it boils down to priorities. Nothing wrong with that; priorities can & do change. If you really wanted to take your detector, you'd find a way, as you already do. 😉

99% of the time I don't have time

People say they don't have time, or they can't find time. I say BS. I learned... A long time ago in a galaxy far, far away.... if/when you really want something--or to make something happen--you MAKE the time.

Vive la différence! 😁

Back in the 1990's I was gold detecting in an old placer mine outside Placerville, CA. One of the teachers that was with us showed us a really neat find, kind of like what you are describing. Anyways, long story short, that rock might have something inside of it. Have it opened up for inspection. You can wrap it in towel and break it up with a hammer, have a chemist dose it with sulfuric acid to eat the outer layers away. That teachers finding was a piece of quarts and he had a chemist dose the outside until there was a beautiful gold nugget exposed.
