The History of the Metal Detectors

The History of the Metal Detectors

The metal detector was first discovered by Dr. Gerhard Fisher, a German immigrant, during the late 1920’s and early 30’s. Dr. Fisher had invented and patented a working aircraft radio direction finder, which even Albert Einstein found intriguing. An adverse property of the patented aircraft direction finder was that it sometimes went awry when a large metallic object or other conductive situation occurred in the vicinity of the equipment as it was being used.

By studying those individual phenomena, Gerhard Fisher learned that these metallic objects were disrupting the electronic field between the transmitter and receiver of his devices. Extrapolation to the fore, he then went on to develop and invent his first metal detector, the Metallascope, in 1931.

He and 4 employees began manufacturing the Metallascope, which consisted of two large flat wooden boxes with copper wire coils inside, and circuitry which included 5 vacuum tubes and other various electronic components. From these humble beginnings in Gerhard Fisher’s garage in Palo Alto California was born the modern metal detector in all its variety and significance. Fisher laboratories continue to produce electronic metal detectors to this day.

Fisher Labs was recently purchased by First Texas Holdings Corporation, manufacturers of Bounty Hunter and Teknetics metal detectors.

The invention of the metal detector was the beginning of a new age. Never before had anyone know where all the money was going. The moneyers of the world had always blamed nefarious forces, the hoarders and what have you, for the disappearance of coinages worldwide throughout time. The real reason money kept disappearing is because the human race is a bunch of fumble fingered gumbies. The metal detector proved this in no uncertain terms, for the first time ever. This is why precious metals were removed from circulation by world banking.
