Conductivity Scale

[Canewrap]

Does anyone have a scale of conductivity for typical U.S. targets? Was wondering where a U.S. Nickel compares to a lead CW bullet? And, where is iron on that scale?

Unfortunately its going to very from make model and machine there is no set rules, whites detectores have the most typical sort of target IDs conductivity out there in general that you can find.It also will very by soil conditions etc etc.IMHO

Should be standard reading in every detectorist library.

It will vary widely with the detector you have. What detector are you wanting the scale for?

Whites 6000 meter as follows
iron 0 or very low readings
12 to 22 small foil, thin rings
24 to 30 nickel
30 to 42 pulltabs
42 to 50 alum screw cap
52 zinc
62 to 68 copper penny, dime
high 70 quarter
high 80 half
90 something dollar

If you mean like a 3 ringer or minnie,
it should read around the zinc range.
Of course meter readings can vary
and I am trying to go from memory
since I no longer have 6000 but that
should be in the neighborhood.
Nickels read fairly low on conductivity scale
of non-ferrous items while zinc is considered
about halfway point.
