Along my journey to create the best PI machine using regular electronic components (i.e. no ADC's or microprocessors etc.), I have reached a point where my limiting factor to better sensitivity (SNR) is the need to eliminate/reduce EMI that is picked up by the search coil.
Does anyone have...

Has anyone tried ESD tape for shielding PI coils?
I have looked at many ESD shielding sticky tapes in various widths.
One of them has a specified resistance of only 10? to 10E4 (1 to 10k).
The others all have very high resistances in comparison.
Might this be interesting for shielding a PI coil,
has someone... -

Found this picture of a RF? choke on the coil cable of a metal detector on the bay.
Since I have not seen this on coil cables before I am wondering if this
might help cutting down on EMI - or is it just wishful thinking?
