I was detecting a big open area yesterday where a school used to be.I got a repeatable high tone and dug a small,gray colored on the outside, rock.It is much heavier than it should be for it's size.I compared it to the 9 1/2 pound meteorite my neighbors found and it appears to be the same composition.Their's was checked out by a meteorite hunter and he confirmed it was a meteorite piece,not hot rock.This is the second one I have found,The first was a piece,half the size of my fist.I found both with my CZ 70.Bill
