What is a "hot" rock?

Can someone explain what a "hot" rock is?

I've been finding things that I can't explain as being anything else but rocks, but they register on my MD and pinpointer.

Could these be "hot" rocks?

Thanks in advance,
Renee

Yes, they have a mineral content that the detector reports as a good target. You can turn up the discrimination or turn down the sensitivity a little but you will lose a little depth and might cancel out detecting a thin gold ring.

One beach I detect has a great number of these mixed with the sand. I've tested my detector on a clean area of ground and balanced the detector. Then I lay some "hot rocks" down near some thin gold rings of various Kt. and see how the detector behaves. Many detectorist just tune these rocks out an don't know what targets they are passing over for others to find.

Thanks for the info!

This hobby sure takes in a lot of different areas! Now I have to learn about rocks and minerals, Civil War, Revolutionary War and history in general.

A hot rock, or cold rock, for that matter, is a rock or pocket of soil that has a different amount of mineralization than the surrounding soil. I believe this a basic explination.
