Pulltabs

That depends on what settings you're using. They pretty consistently VDI low (high teens or low twenties), so if you're rejecting low VDI numbers, then yes, they'll be rejected. If you're accepting low numbers, then naturally, they will be accepted. You can use the frequency response to help decide whether it's a pulltab or a nickel.

Can someone post a graph of a nickel and a graph of a typical pull tab.....pull tabs can be all shapes and sizes and bent etc.....what type of "signature" are you looking for with a pull tab?

Yes, I realize that from the Minelab (why the heck can't they build a machine yet that can tell the difference between aluminum and gold in the ground anyway), butI would at least want to be able to tell the difference between a nickeland a pull tab.

Any ideas on why we still have such a hard time telling gold from aluminum in the ground - such very different metals - surely there must be some sort of signature that gets transmitted from the induced signal. Have you guys tried any heavy duty DSP algos that might detect a difference?
It's not something we haven't been trying to figure out (how to tell the difference). But, the signatures really do come in very similarly and when ground is added in the mix, it's just better to let the operator figure out what is best in their own ground. I personally don't know why they are so similar, but maybe Carl can answer that one.
