* Gold responds well to radio frequencies because of its high conductivity and does not corrode like other metals in the soil. The high density of gold makes it interact greatly with radio frequencies and has a significant effect on the radio frequencies reflected from its surface. It reflects the radio signal well
* Metal detector radar uses radio frequencies to penetrate the ground to accurately detect metals. The best medium frequency range. This range is balanced with penetrating power and accuracy.
* Schottkine diodes are better than germanium for detecting weak electrical signals. ( Pin diodes) are specialized in very small capacitances and are used when high-sensitivity detection characteristics are needed.
* Photoelectric technology uses light to detect metal resonances by measuring changes in light

Hi Omar!
this description is very interesting and I think very accurate!
