Metal Detectors Through The Ages
Metal detectors got their start late in the 19th century. With the knowledge that scientist were acquiring in this technology it led to the development of the metal detector. One of the first known use of a metal detector was Alexander Graham Bells account, he used a metal detector he had made to locate a bullet lodged in the chest of then president Garfield.
In 1930, the next big step was taken in modernizing metal detectors. It was Gerhard Fisher who first came up with the notion to use radio frequency as a means to develop a more practical metal detector. Once Lieutenant Josef Stanislaw Kosack refined this radio frequency idea, these metal detectors were used extensively to clear away land mines that were left behind from the retreating Germans in World War II.
Further development was brought on by people such as Charles Garrett and Mr. White. With their respective inventions such as the Oremaster Geiger Counter and the BFO (Beat Frequency Oscillator) machine, and the development of the transistor the modern metal detector was born. “Todays models are fully computerized, using integrated circuit technology to allow the user to set sensitivity, discrimination, track speed, threshold volume, notch filters, etc., and hold these parameters in memory for future use. Compared to just a decade ago, detectors are lighter, deeper-seeking, use less battery power, and discriminate better.”
Today metal detectors are use extensively, they are used in the pharmacutical, food, home land security, entertainment industries. We trust metal detectors to keep us safe and to provide hours of enjoyment when we go treasure hunting.
