For all LRL dreamers: 25 feet (7 m) underground

History buffs using the cameras, which can scan objects as deep as 25 feet underground.....

These cameras measure either heat or infrared levels on the surface
They don't hit the ground at all
I used both models, but only the heat or the infrared wave that was present on the Earth's body.
You can't trust 100%
Underground animals
Rotten roots
Concentrated jar and silica
Shaved grass stacked on top of each other
Coal and minerals
All metal spells
He feels many other things
They have a lot of mistakes and they are not reliable

Yes, that is limitation.

But heat on the surface always represent inner soil structure (inner structure temperature

conductivity in time span - so it is importan to take measure at the proper moment).

Another important factor is how precise is camera in its resolution.

I tested thermal camera (not very precise and expensive) with buried clumps of

coper wire and it was able to differentiate buried position of metal from surounded
soil till about 10cm of buried depth of metal.

The Thermal scan is very well

Nice test Nicolas..

Are those cans filled with water or empty?

Empty cans have poor heat accumulating properties.

Those cans is totally Empty but in Saudi Arabia have much humidity.
