For metal detectors

Metal detector is a device that signals in the presence of metal objects in its scope.
The operating principle of metal detector is based on radiated electromagnetic field. The first metal detectors were developed in the 1960s and have been used primarily in the mining industry, in the security business and from the army. We’ve all seen on the news and movies, how metal detectors are used for localization of anti-personnel mines. Many of us have “met” with metal detectors at airports or in other areas with enhanced control of security. Metal detectors are invaluable to the development of science – the excavations and the study of historical heritage made the big jump thanks to the use of metal detectors.

Best metal detectors for hobby

History and development

 

At the end of the 19th century, many scientists and engineers have used the expanding knowledge in the field of electricity to seek a way of inventing a machine with metal. Using such a machine the discovery of iron ore would give a huge boost to the mining industry. German physicist Heinrich Wilhelm Dove discovered the Foundation of today’s metal detectors. The first metal detectors were inaccurate and have expended a lot of energy. In addition, they bumped into each other in a very limited range. Alexander Graham Bell used a similar device to find the bullet in the jaw of  President James Garfield in 1881

 

The first “real” metal detectors

 

Were developed in the early 1930s. Gerhard Fischer develops system to capture radio waves, which were to be used for navigation. The system worked quite well, but Fisher noticed that there were anomalies in areas rich in ore. He discovered that radio waves are upset by the presence of metal, and in consequence of this discovery is possible to develop a machine that detects metal. In 1937 he developed the first patented metal detector.
After numerous improvements and small discoveries today use accurate and precise metal detector.

 

Nowadays metal detectors find application in many areas of life:
Archaeology: metal detectors are indispensable assistant in modern archaeology. Unfortunately one of the drawbacks of accessibility and high quality of the metal detectors is the stormy development of treasure hunting.

 

Metal detector to the beach

Techniques for metal detecting on the beach

As a hobby:  the use of metal detectors just for fun is gaining momentum. There are several branches of sport hobby:
-demand for money: after events with the addition of many people is quite common to find a small fortune in the form of scattered coins. The regular “crawl” after a football match, a concert even political rally quickly will reimburse you the cost of newly purchased metal detector
-Lou prospects, too: quite popular in North America. With the help of metal detectors looking for gold nuggets

Treasure hunt: in some areas of the world where romantic legends tell of pirates, medieval battles, Royal intrigue always have secrets buried treasures
-Search of lost belongings: especially popular on beaches. I really can not imagine how many things can lose people along the beach.

 

Security and law enforcement

 

Maybe relatively late metal the detector goes into the work of law enforcement and the military. Metal detectors are indispensable means of locating explosive devices and mines. Metal detectors have already required attribute of public places with a large human stream and places with a particular security mode. Even at home in recent years, there’s no way to get into the Court, the prosecution, the district management, etc. without having to go through a scan.
