shielding the 7K

was wondering whether anyone has found a shield that fits above the coil to stop the field of detection from rising--would rather the field go downwards to zap any gold in the area.

just putting it out there.

Yeah that's something I'd wondered about about too Ray for a long while ,for my 5000 coils .Even posted that query on the ,what is it again Ray ,the knitting club forum ?1  ages ago ,still waiting for a reply  .Months ago got xrayed and got given a tea towel size blanket to cover my groin ,and I thought at the time ,well if this little light weight cloth is supposed to protect me ,why couldn't this also ,or something similar help shield the top of a coil better
