Conductivity, permeability, susceptibility tables of somes...

Is possible magnetic resonance in PI? (Larmor), but i think involves much gauss and current.

The problems are what they have always been: a large piece of any metal listed, can look like a small piece of another. That is why I keep coming back to clock speeds of return signals through a microprocessor to go to the next level. If you can get the speed of the return, you can judge the size, and if you can judge the size (along with the conductivity), the microprocessor can figure out what it is via a pre-loaded tables for metals, and if we know what it is (Whites for instance gives a % probability on a display (MXT-VLF) we can decide to dig or not.
I sure hope all this can be figured out in my lifetime.

OK, so most important is density... I think the solution is an electronic densimeter via ultrasonic beam, for example, this is an idea in my mind. Via computer software the MD shows the density of the metal previous analisis of the density of the terrain... Ideas

It can be done with increased number of sampling and comparing, but so far no one has programed a chip to do it, I suspect in the near future it will be in next advance in PI.

I think, as Don pointed out above, the ultimate is probably within grasp right now. The question is, who will take the leap and build it? Probably, the pulse market will be driven by the multiple band detectors in the VLF mode, as they are fast becoming what the majority of people want (a screen that tells you what it is, how deep it is, what it is likely composed of). Most of us in the pulse world are (gasp) techno-geeks obsessed with depth, mineralization, or other issues (scuba) and it is a small market. There is another, darker side: if you build what we pretty well know is achievable, you knock out not only the competition's line, but the rest of your own line becomes virtually unmarketable overnight. Many of these small companies put on a brave face, but essentially operate on a shoestring, and that is an unthinkable thing to happen. Much more sound business to market by evolution than revolution -- so we may have to wait awhile, and be offered true discrimination for this metal, but not that other metal, and tones for this, but not for that, until we finally get what somebody probably knows how to build right now in one box.
