Multi-frequency discrimination or Molecular Frequency Discrimination. The term refers to devices known as Long Range Locators used to find buried treasures, water, archaelogical sites, etc. We are told that Noah's Ark was discovered in Turkey using one of these things! Others deny this, claiming that the alleged Ark had been exposed for years, was easily visible from the air and known to the locals.
The main reason the world does not know more about these wonderful devices is because their users are mostly engaged in illegal activities. Of course, they don't think of it that way. According to them it is because of "State and Federal beauracracy" which "has made permitting so restrictive and the penalties so severe that there is a fear of announcing the smallest of finds."
As far as I can tell, an MFD is some sort of electronic device which can detect metal, infrared frequencies, temperature, magnetic fields or some other known property of physical objects. The likelihood that an MFD can distinguish Noah's Ark from a trash heap or buried treasure from buried garbage is about the same as a metal detector telling the difference between a gold watch and a pop top from a beer can.
