VLF metal detectors are very sensitive to iron. Can iron be rejected while gold nuggets are still found?

Iron can be rejected by a VLF discriminator while still having the ability to detect gold if the discriminate level is set very low. Doing this, however, means that tiny pieces of gold may be lost due to the fact that the signals they cause are below the reference level of the electronic detection circuitry of the detector. The best way to hunt for gold is still in the All Metal mode, preferably with a detector designed with the extremely high gain necessary to detect the little pieces.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
