explain me some things , if there is a metal box buried in 2meters underground you can see at the camera the metal box as it is live ? You went down there to buy the machine or to see how it works ?....it works like x-ray ?...for example , there is a metal box buried 2 meters down when you look inside the camera you see the metal box straignt without seeing the ground between you and the box ? ...if it happens something like that it is to dificult to belivie without some video from the event ! Does he sell's the machine and if it's yes what's the price ?
