LRL with camera!!

[long]

Hello to all!

I was last month in Iran and I visited a man with his LRL. the LRL was an excellent locator because it has a camera and the owner was able to see anything under ground till 20 m deep. the camer of LRL was not a thermo camera but also a real camera was that. I mean he was able to see the things in real form. But nobody has ever seen this LRL because it is a black plastic and if he will work with the LRL he dos not need to remove the plastic. That is the reason why no body know which type of LRL is it.
Do you know about this LRL?
I'm sure which this LRL uses a special laser because one time I stand in front of the LRL and the man start on that and I became a vibration in my leg for a short time.
