This is a phase-type VLF detector which utilizes a very simple coil configuration. In fact, it is an example of a TR detector that is not induction balance! The author claims that it does well with the "ground effect" but he is talking about ground capacitance, not mineralization, and the design does a poor job (if any) discriminating between precious metals and junk. However, it is good reading for learning about phase detectors and might make a good starting point for designing a decent VLF discriminator. Practical Electronics is now known as Everyday Practical Electronics, a popular electronics magazine that is owned by UK publisher Wimborne Publishing, Ltd.
