The 12 Line

My understanding is that the conductive and ferrous grid in the CTX (and etrac) aren't really measuring the ferrous content or conductiveness of the metal. They are simply names that Minelab engineers assigned to the 2 readings. The FSB technology improved on the single number target ID and included a second measurement. In an attempt to eliminate false/duplicate numbers on different metals. The circuitry pushes likely target metals to the 12 line and then differentiates them using the other "reading". It also depends on what mode you are in. As you have prob already noted some modes will show silver and some other metals as a 01-xx number. For detectorsists, it allows another "cross check" to assist in target ID. I got my (obviously vague) understanding of this information from the CTX book by Andy Sabisch. A quick read through the beginning section on FBS technology will give you a much clearer explanation. Or, maybe someone here will offer some specifics.

Architex --
Yep, coherent is correct.
Detector ID numbers don't actually measure metal composition, of course -- which I'm sure you know. As I understand it -- similar to coherent's understanding -- Minelab's algorithms within FBS units process return signals in such a way that they can extract extra "pieces of information" from the waveforms of return signals that can't be extracted if utilizing a single-frequency platform. By doing comparisons between return signals from the different frequencies employed, the extra information extracted (or "removed," in the case of ground mineral contamination) is then plotted in x-y coordinate space, giving us the smartfind graph and the FE/CO numbers we are used to. Calling them "ferrous" and "conductive" numbers, though, are apparently not really "accurate" descriptions of these mathematical pieces of information, and CERTAINLY are not "measurements" of the actual target's metallic composition.

Not sure what "Al Gore's rhythm" has to do with it, but OK.
