Locating a man made tunnel

[gopal123]

I have just done this methodology once to outline a departure burrow from the world's biggest jail in Iraq. It was horrendously moderate, however it worked. The main explanation I did it was that a previous partner demanded that I didn't require the exchanging resistivity framework, yet once on location the base leader truly needed us to confirm the passage area. It took three days to do a study that would have taken a couple of hours with a programmed exchanging framework.
