Todays finds.
the brass copper square thing,
Any Ideas what its for.

Now I detected a signal in an old tree, nice as this is what
I am looking for.
IT is
Tin or old can, but well if some 1 years ago
hid coins in this can, my question is
would I pick up the tin or would the coin value that might be
inside the tin shine thru and it looks like at least 7inches
detecting space to the center of the tree.

If the tin has all but rusted away you get a chattery signal that shows up both the high and low tones,... as you dig down the pinpointer gives off a loud close signal,....excepy as you dig expecting the target to be just down a bit you find zilch,...but signal still there,....eventually you dig through a layer of soil that is just rust(used to be tin lid) then more dirt,...still great target sound,...eventually you get to the goodies that used to be in a tin,....so after the rust level you need to go in carefully as you will have a close signal all the way to the targets ,...especially if there are a lot of them.
