 How Does It Work?


Okey, so let’s geek out a little about how metal detectors work

Generally, metal detectors use magnetism,  electricity and pulse induction (PI) technology.


Walk-through metal detectors work with a special coil in the midst of the machine, as well as on its top and both sides. The coil has a receiver and special transmitters to detect metal materials when someone walks through the archways. 


These days, walkthrough metal detectors are a part of schools, buildings, events, offices and concerts total security system along with cameras, door controls and emergency systems.

Metal Detector History


Well, in time at least. Metal detectors have came a long way. Here’s a brief history about them. 


1874 – Gustave Trouvé, a French electrical engineer invented a metal detector to find and remove metal objectives from people. 


1881 – Alexander Graham Bell made a primitive model of a metal detector. When President Garfield was shot, Bell assisted physicians by inventing a metal detector to find the bullet from the president’s body. The detector worked, but the metal coils from the president’s bed confused the detector. So the detector failed to find the bullet. 


1925 – Gerhard Fisher applied for the first patent for his metal detectors inventions


1941 – Polish Army engineer, Lieutenant Józef Kosacki created the first landmine metal detector. It was a long wand and dish which they used for military operations. 


1950 –  Charles Garret pioneered the Beat Frequency Oscillator machine. These were the first metal detectors with batteries, circuitry and portable designs. 


1958 – People began using metal detectors for archaeology. Don Ricket used one to map the site of the Battle of the Little Bighorn.


1972 – Metal detectors were first used in airports in the United States. 


Present time —  metal detectors are used for security, item recovery, research, hobbies and archeological exploration.
