The item is not much but was found 7 inches deep with the 5 inch Accelerator coil. I was testing it for depth and was surprised to find several clad coins at 6 to 8 inches deep. I believe I will use it more in junky areas. The stone is glass and the finish is plated silver. I also found a piece of iron 1.75X.5X.25 inches at the depth of my X1 pinpointer which is about nine inches. It rang up as silver. The depth scale was clear below the bottom on several finds but could still be pinpointed on the coil. The detector was an Explorer SE.
