What is a Metal Detector?

A metal detector is an instrument used by the police, military or security authorities of the like to detect metal that can be or can act as a weapon. It is an electronic instrument that is formed on the theory of electromagnetism which is the combination of two fundamental theories of physics electricity and magnetism. Usually, it has two coils that stay attached to a handle through which electricity passes to the coils and they are able to form magnetic fields around them to detect the metals.

Its main purpose is to help detect metal nearby. It consists of a sensor that detects any hidden within other objects (or not) metal in its a magnetic field, be it buried somewhere within the ground. After sensing or detecting the metal, the metal detector indicates so through the use of speakers. As soon as there will be a signal, the speaker started producing a sound that would be audible. They detect tin, copper, nickel, iron, aluminum, lead, gold and metals as such.

They are usually used by security pales to detect weapons such as guns, knives and the like but they are also largely used in archeology to discover valuables from the past. They are also used as a hobby by many people as they go for treasure hunting, coin shooting or be it looking for lost valuables. There are different types of metal detectors, each having their own purpose and their own field of expertise. Sometimes they differ on the basis of their advanced technology and the purpose of their use while at other times they differ on the basis of the metal detector depth chart.

How Deep do Most Metal Detectors go?

Metal Detector Depth Range

The type of metal detector also depends on metal detector depth which is the depth up to which a metal detector can detect. Metal detector depth range becomes very important when one is doing archaeological research us using it as a hobby for coin shooting. By asking about the metal detector depth range what you are actually asking is “up to what depth can the metal detector detect metals buried into the ground?” Here is the simple answer: to generalize all the types and metal detector depth range, an average metal detector can detect metals buried into the ground up to the depth of 6 – 10 inches.

But other than the basic capacity of the metal detector, there several factors that determine how deep a metal detector can detect like soil, for example, it becomes extremely difficult for metal detectors to detect metals in clay soil no matter what the metal detector depth is. Other factors include the size of the object or the period in which the metal was buried. The metal detector depth range is also determined by the machine that we but not it’s capacity but other factors like its condition, the size of its coil (which is the main instrument in detecting metals), its batteries and the like.

Best metal detector for depth is the highest tech ones (obviously). This keeps on changing year after year and the metal detector depth range keeps on increasing. The latest best metal detector for depth can detect up to the depth of 12 inches or one foot.


A metal detector is an important instrument for security and also for archeology and people whose hobby include coin shooting or treasure hunting. The metal detector helps in detecting weapons or things that can be used as such are detected by the security personnel through these metal detectors. And for the archeology and coin shooting the metal detector depth becomes very important. But the metal detector depth range does not just depend on the capacity of the machine but also on other factors like soil, size of the objects, and things as such.

However, the best metal detector depth can be found in the most modern of technologies that come with most expensive of the prices. It becomes important to not only know the metal detector depth, for being able to use it to its full potential one has to know the technicalities and should have that level of expertise.
