hi to all
Today finished my project.passive detector based on vlf and elf frquency.

The results are very interesting for me.I was able to detect the fluorescent lamp at a distance of 3 meters in elf mod passive and 2 meter in vlf passive.

i was able to detect monitor pc at 4 mete in 2 mode vlf and elf .I am not fit to be tested.

I will reveal the buried metal?
What do you think?
I put a video
