Hi Clive,

Copper is paper sticker
http://www.ebay.fr/sch/sis.html?_nkw=CUIVRE%20COPPER%20AUTO%20ADHESIF%20BLINDAGE%20PICKGUARD&_itemId=300466986798

available on ebay for electric guitars, for example
they too research EMI shielding

Yes, a maximum of ferrite bead
throughout the jumper cables in the box, will reduce noise

Hey thanks Denis big guitar shop near here im sure they will have it. Hey a question--with any of Eric's machines you have owned that have a choice of two audio tones--which did you prefer?
Also, did you actually solder to that thin copper foil or glue?
Tried my tinfoil shield what a difference!

Hi Clive,

the cable is welded with tin (better conductivity)

I had 9 pulsepower
8 different model, one duplicate the Goldquest SSV3

this is the best audio I've ever seen on a pulse
with a little practice can recognize the aluminum, lead and gold course
with different tonalitées
shame that Eric does not continue and released a high voltage
with audio V3

Done--and it sounds great--very smooth now. Board is encircled with copper shielding and grounded. Also, thanks for the GG suggestion--thought I would try my Mr. Goldmaster's and holy crow they work.
So instead of putting a ferrite pod on the coil cable you say it should go on one of the internal leads? Would that be the power lead?
cjc?

i noticed one of your machines has a meter...is that iron discrimination ??? if so can your machine reject ferrous nails maybe at depth...or does that meter work on large size ferrous ???

Hi,

update my collection

red goldscan 5 is for sale

Good sale buddy.
Probably doubled your investment.
Ain´t many electronic articles world wide that can ever match this price increase when sold used at such an age.
And this is not poking a stick at Eric `cause he only built so few of them - on the contrary - it should rather make him proud - as well deserved.

Couple years ago I lined my plastic box with copper foil tape. Soldered a wire from the lid to the bottom box then attached it to the PCB.
I also coated the copper tape with a layer of epoxy.

I also built a copper box that fit inside the control box.

Now have a different way of doing it, works just as well as the above.

They also have spray on EMI coating paint. Have a can here, just haven't tried it yet..
