It all began with the innovation and ingenuity of a Scottish physicist named Alexander Graham Bell. Yes, the same Bell who is famous for inventing the telephone! In 1881, Bell created a device called the induction balance, which was the earliest form of a metal detector. The induction balance worked by using two coils, one to create a magnetic field and the other to detect any disruptions in that field caused by metal objects.
It was a groundbreaking invention that laid the foundation for the modern metal detector. However, Bell’s induction balance was not widely used at the time and was primarily utilized for finding bullets in wounded soldiers during the First World War. It wasn’t until the 1920s that metal detectors gained popularity among treasure hunters and archeologists.
During this time, the first commercially available metal detector, known as the “BFO” or Beat Frequency Oscillator, was introduced. This device used electromagnets and radio frequencies to detect metal objects. Since then, metal detectors have evolved significantly.
Today, we have advanced machines that use multiple technologies like pulse induction and very low-frequency technology. These detectors are capable of accurately locating a wide range of metals, from coins and jewelry to historical artifacts and buried treasure. So the next time you see someone sweeping a metal detector over a sandy beach or carefully scanning an ancient site, remember the journey these devices have taken.
Introduction
You might be wondering, who made the first metal detector? Well, the credit goes to Alexander Graham Bell.

Early Developments in Metal Detectors
Who made the first metal detector? The development of metal detectors can be traced back to the late 19th century. In 1881, Alexander Graham Bell, the inventor of the telephone, created a device called the Induction Balance. While this device was not specifically designed for metal detection, it was able to detect metal objects by producing a magnetic field and measuring any disturbances in that field.
However, it was not until the early 20th century that the first true metal detectors were developed. In 1925, Gerhard Fisher, an engineer and inventor, developed a new type of metal detector that used radio waves to detect metal objects. Fisher’s invention marked a significant breakthrough in metal detection technology and laid the foundation for future innovations in the industry.
Invention of the First Metal Detector
During the late 19th century, the first metal detector was invented, marking a significant milestone in the history of technology. Early developments in metal detectors were primarily driven by the need to locate and retrieve buried metal objects, such as lost treasure or weaponry. The first metal detectors were crude and relied on the principle of electromagnetic induction.
They consisted of a simple circuit and a search coil, which generated an electromagnetic field that could detect the presence of metal objects nearby. Although these early metal detectors lacked the sophistication and accuracy of modern versions, they laid the foundation for further advancements in the field. As they evolved, metal detectors became smaller, more portable, and more sensitive, making them invaluable tools for archaeologists, treasure hunters, and security personnel.
From locating buried artifacts to ensuring public safety, metal detectors have undoubtedly revolutionized a variety of industries. The invention of the first metal detector not only sparked a new era of exploration and discovery but also paved the way for future technological breakthroughs.

Further Innovations in Metal Detector Technology
metal detector technology, innovations, early developments, burstiness, perplexity. In the early days of metal detector technology, there were some fascinating developments that laid the foundation for future innovations. One of the earliest breakthroughs was the use of oscillators to detect metal.
These oscillators produced electromagnetic waves that would bounce off metal objects, allowing them to be detected. This was a major advancement at the time, as it allowed for more accurate and reliable detection of metal. However, there were still some limitations with this early technology.
For example, the oscillators were not able to differentiate between different types of metals, meaning that they would give a similar signal for both iron and gold. This created a sense of perplexity for users, as they had to manually dig up the targets to determine if they were valuable or not. Additionally, the early metal detectors were not very burstiness and were quite clunky and heavy to operate.
This made them less user-friendly and limited their practical applications. However, these early developments paved the way for further advancements in metal detector technology.
The First Commercial Metal Detector
In the late 19th century, Alexander Graham Bell, primarily known for inventing the telephone, also played a significant role in the development of metal detectors. During his work in the field of telecommunications, Bell discovered that certain metals could interfere with the transmission of signals. This led him to experiment with electromagnetic principles and devise a device that could detect metal objects hidden within the human body.
His invention, called the induction balance, marked the first commercial metal detector and was primarily used in finding metallic foreign objects in patients. Despite its medical application, the induction balance laid the foundation for the metal detectors we know today, which are widely used in various industries such as archaeology, security, and treasure hunting. So, while Alexander Graham Bell is primarily recognized for his telephone invention, he also made significant contributions to the world of metal detection.
The Development of Walk-Through Metal Detectors
“walk-through metal detectors” The development of walk-through metal detectors can be traced back to the invention of the first commercial metal detector. Before these devices were introduced, security checkpoints relied mostly on handheld metal detectors which required physical contact with individuals. However, as technology advanced, the need for a more efficient and non-invasive method of detecting metal objects became apparent.
The first commercial metal detector was invented by Dr. Gerhard Fisher in the 1920s. Originally designed for the purpose of locating lost objects in the ground, Fisher’s invention quickly gained attention from the military and law enforcement agencies.
It wasn’t long before the potential for security applications was realized. Over the years, the technology behind metal detectors evolved, leading to the development of walk-through metal detectors. These devices allowed for a more streamlined and effective approach to security screening.
Instead of individually scanning each person with a handheld detector, individuals could simply walk through a portal equipped with metal-detecting sensors. Today, walk-through metal detectors are commonly used in various settings such as airports, government buildings, schools, and entertainment venues. They have become an essential tool in maintaining public safety and preventing the unauthorized possession of weapons or other dangerous objects.
