Bell’s metal detector was designed to locate the bullet inside Garfield’s body.

However, it wasn’t until the early 20th century that the modern metal detector as we know it today was invented. In 1925, a Polish-born inventor named Gerhard Fischer invented the first portable metal detector. Fischer’s invention used a coil of wire and a high-frequency oscillator to detect metal objects buried in the ground.

Over the years, metal detectors have continued to evolve and improve, with advancements in technology allowing for greater accuracy and sensitivity in detecting metals. Today, metal detectors are widely used by treasure hunters, archaeologists, and law enforcement agencies. So, the answer to the question, “What year was the metal detector invented?” is 1925 when Gerhard Fischer created the first portable metal detector.

Early developments in metal detection technology

In fact, the history of metal detectors dates back to the 19th century. The first metal detector was invented by Alexander Graham Bell in 1881, with the primary purpose of locating a bullet lodged in President James Garfield’s body after an assassination attempt.

Although Bell’s detector was not successful in finding the bullet, it laid the foundation for further developments in the field. Fast forward a few years to 1925 when a Polish engineer named Gerhard Fischer invented a portable metal detector that could be used for practical purposes. Fischer’s device was based on the principles of electromagnetic induction and utilized a coil and oscillator to detect metal objects.

This invention marked a significant milestone in metal detection technology and paved the way for further advancements. In the 1930s, the military began to recognize the potential of metal detectors for locating landmines and unexploded ordnance. The development of metal detectors during this time focused on improving sensitivity and portability.

Engineers experimented with different coil designs and electronic circuitry to enhance the detection capabilities of these devices. However, it wasn’t until the 1960s that metal detectors became more widely used and accessible. Companies like Garrett Electronics and White’s Electronics started manufacturing metal detectors for the general public, making treasure hunting and relic hunting popular recreational activities.

These early metal detectors were simple and relied on analog technology to detect metal objects. In the late 20th century, digital technology revolutionized metal detection. The advent of microprocessors and digital signal processing allowed for greater accuracy and discrimination of metal targets.

Modern metal detectors incorporate advanced features such as target ID, depth indicators, and ground balance adjustments, making them more user-friendly and efficient. Today, metal detectors are widely used in various fields, including archaeology, security screening, and industrial applications.
