How Does A Gold And Silver Detector Work?

How Does A Gold And Silver Detector Work?

The operation of a gold and silver detector is not as simple as it seems.

Did you know that the metal detectors apparently date back to the shooting of the President of the United States, James A. Garfield, in July 1881?

One of the bullets directed at the president was lodged inside his body and could not be found. Telephone pioneer Alexander Graham Bell quickly improvised a metal-locating electromagnetic device called induction balance, based on an earlier invention by German physicist Heinrich Wilhelm Dove.

Although the bullet was not found and the President died later, Bell's device worked properly, and many people credit it as the first electromagnetic metal locator, or gold and silver detector.

Portable Gold and silver detectors were invented by Gerhard Fischer, an electronic engineer born in Germany (who also spelled "Fisher") while living in the United States, and he applied for a patent on the idea in January 1933.

He called his invention the Metalloscope-a "method and means to indicate the presence of buried metals such as minerals, pipes or the like".

In the same year, he founded Fisher Research Laboratory, which remains a leading manufacturer of metal detectors to date.

Dr. Charles L. Garrett, founder of Garrett Electronics, pioneered modern electronic metal detectors in the early 1970s. After working for NASA on the Apollo lunar landing program, Garrett focused his attention on his love of treasure hunting or hunting for amateur gold and silver and his company revolutionized the field with a number of innovations, including the first computerized metal detector with digital signal processing, patented in 1987.

But you probably want to know for sure, how does a gold and silver detector really work?

What makes a gold and silver detector buzz when you pass it over buried treasure? Why is it important to keep the detector moving?
This is the way it works:

How a gold and silver detector works

  • A battery at the top of the metal detector activates the transmitter circuit (red) that passes electricity down through a cable in the handle to the transmitter coil (red) at the bottom.
  • When electricity flows through the transmitter coil, it creates a magnetic field around it.
  • If you pass the detector over a metal object (like an old grey wrench), the magnetic field penetrates directly through it.
  • The magnetic field causes an electric current to flow into the metal or gold and silver object.
  • This flowing electric current creates another magnetic field around the object.
  • The magnetic field passes through the receiver coil (blue) moving over it.
  • The magnetic field causes electricity to flow around the receiver coil and up to the receiver circuit (blue) at the top, causing the loudspeaker to vibrate and warn you that you have found something.

 

So, since you know how a gold and silver detector works, what do you expect to have one and get down to work with your hunt? Here are some treasures to be found in Latin America.

Detector Online Training

With your new detector, you will receive a Quick Start Guide, a valuable resource designed to guide you through the essential steps of operating your new device seamlessly. This user-friendly guide is tailored to ensure that even beginners can quickly grasp the fundamental functions and features.

For those seeking a more profound understanding, a comprehensive manual accompanies your purchase. This detailed manual delves into the intricacies of your detector, providing a wealth of information for users eager to explore advanced settings and capabilities.

However, the pinnacle of expertise in harnessing your detector's full potential lies in professional training. While guides and manuals offer a solid foundation, professional training takes your knowledge to the next level. Through hands-on instruction and insights from seasoned experts, you'll gain a deeper understanding of your detector's nuances and unlock its optimal performance.

During the individual training, our detector Expert addresses your wishes and questions, provides you tips and tricks and helps you to improve your chances of success with your detector.

  • Theoretical introduction
  • Overview of the functionality and operating modes of your detector
  • Using the detector on the test field
  • Tips and tricks for advanced users
  • Improving your measurement procedure
  • Evaluation of the scans on the detector display
  • Answers to your questions

In addition to a general introduction to the functionality and operating modes of your detector, the detector Expert explains how to use the detector efficiently in the field. In doing so, he can correct small errors during the measurement and advise you on special features of your search projects.

You will learn how to check your measurements and further improve your scanning technique independently. You can also draw initial conclusions about potential target objects in the underground.

  • Service & Support: for entry-level, experienced and professional detectorists
  • Schedule: After you add the paid training, we will contact you to schedule your training with our expert.

Trainings are charged per hour! Additional costs may apply for training sessions. For special requests please contact us at info@detectorpower.com
