I managed a short outing today at the beach... garnered a quarter, penny, beach glass etc...but am mostly curious about this black slaggish rock...not heavy...that gave a nice clear signal...what is it?

Thanks in advance,

It looks a little bit like a worn/tumbled piece of coal… Dark or black rocks like hematite, magnetite and coal, as well as objects from outside our atmosphere—aka—meteorites will all set off a metal detector. Slag will also set it off…so there is that too!😵‍💫
It’s hard for me to say exactly what it is, as I’m more of a hands on person and my eyes could be better, but best of luck figuring out that “hot rock”. Someone with more knowledge will pop up sooner than later!👍🏼

Thanks 👍. It does have a melted look to it....maybe an ancient meteorite 😯

That would make sense...I was hoping for a mars meteorite 😏

The silver nugget was my other wish.

Looks like black slag from an old smelter. Look up the history of your area and you can see they had many smelters at one time.
