My PI Depth Catch

[Kmouly]

I have a PI with 1m x 1m coil. It can detect a 15cm x 19cm unused PCB at 180cm easily.
The PCB is detected at 120cm with 50cm coil.

What's your opinions about it?

Is that an air test?

How much metal, and what type of metal is on the PCB?

Yes, It is.
The PCB is unused, there's only the thin copper of its surface and nothing else.

nice

Thats pretty cool, now we can go and find blank PCBs from old Egypt :P
Seriously, some Test Results with other Objects would be great.
And of course the Schematics and Coil Data, if your Friend is willing to share.
