Matel and Gold Detector

Difference between Gold and Metal Detectors

/in /by

 

Aspects GOLD DETECTORS METAL DETECTORS
Purpose Gold detectors have the sole purpose of detecting gold objects buried underground, distinguishing them from the other metallic compounds, or completely ignoring them, because they are not precious.  Metal detectors have the purpose of detecting the presence of metallic objects buried in a medium whether it is ground, water, or otherwise to ensure it can be extracted or taken out of the system successfully.
Frequency Range Gold detectors are specifically designed to work with higher frequencies so that they will only respond to dense and precious metals with precision, and not ignore very close to surface gold nuggets.  Metal detectors are very versatile and depending upon the user requirement and size, they can work on several frequencies and the users have the flexibility to choose a suitable one.
Uses Gold detectors are a very specific type of metal detection instrument that is used for the purpose of finding treasures in form of gold coins, gold nuggets or relics statues, and antiques below ground, underwater, or for other multiple purposes.  Metal detectors are used for all purposes where the metal is required to be separated from nonmetal items for example for security purposes in walk-through gates, in the construction industry, in the retail sector, for physical research, in production of sensitive equipment, etc.
Depth Because of the nature of gold detectors working on a higher frequency, it is very difficult for them to work on very great depths in the ground and mostly work very close to the surface of Earth starting from one inch to a few meters. Because of the versatile nature of metal detectors, they are designed to focus on all or some of the specific class of metal objects, so they can have varying depth options from very less to very high as the frequency of them varies. 
Discrimination In gold detectors, the feature of discrimination is very important because only one metal is the center of attention which is Gold, so it must be separated from other metals during the detection process to avoid wastage of any time.  Metal detectors can be equipped with discrimination or not depending upon how the buyer intends to use them. If they want to use it for the purpose of identifying metals from nonmetals then discrimination is not necessary. But if the user requires to classify the detected metal as a certain type e.g. iron copper, aluminum, or gold, then discrimination in metal detection becomes helpful.
Coil Size Coil size has a variety of options to choose from depending upon the user’s preference, as smaller coil sizes will be more helpful in detecting gold nuggets, but bigger coils will be more helpful to look for bigger gold items.  Coil technology is pretty much the same in both, and size has a variety of options to choose from as well. It also depends on the user’s preference, as smaller coil sizes will be more helpful in detecting smaller items like insecurity, but bigger coils will be more helpful to look for metallic items for example in construction or research. 
Major Difference Gold detectors are a type of metal detector where the emphasis of the detection technology is to classify whether the metal is gold or other nonprecious metals, to target and mine gold from below the surface of ground or water.  Metal Detectors are a major type of detection instrument that uses a specified set of technologies to classify different types of metals or metals in general in a specific location underground or underwater which is not visible otherwise. 

 

It can be safely concluded that every gold detector is a metal detector but every metal detector is not a gold detector.

What Are Gold Detectors?

/in /by

Introduction

The Earth’s surface and core both are blessed with numerous resources which human beings exploit to keep the system running. These resources include precious and semi-precious metals hidden in many different forms below the Earth’s crust. One of the many challenges for people is to locate these metals and do the efforts required to dig in and extract them. Due to the technological advancements, it is now possible to determine if metal lies or not underneath the surface, without even starting to dig in. The modern equipment dramatically decreases the cost by showing probabilities of metal existence under the surface and saves much time. The equipment designed to detect specifically the gold-based metal and metallic alloys under earth’s crust is known as Gold Detectors. 

Categories of Underground Gold

The Gold which is naturally existing below Earth’s crust could be classified into two major types:

Gold Nuggets

The accumulated pieces or chunks of gold metal varying in sizes starting from the size of ballpoint pen’s tip to various ounces formed under natural circumstances by Earth core’s temperature and pressure.

Fine Gold

The gold particles in powdered or dust form mixed with other non-valuable particles from soil, which are not detected by any radiation or contact with the gold detectors. Their size is so small they are unable to affect the detection mechanism of even the powerful metal detectors.  

Basic Types of Detectors

Based on the types of outputs they provide, Gold detectors could be classified into four basic types which are:

  • Analog Gold Detectors

Detectors having an analog output where a needle deflects between two points when in contact with the threshold size of a metallic object showing relatively inaccurate reading but still signifies the presence of the object in question. These types of detectors are mostly obsolete but can be found in very beginner level equipment where precision is not the goal. 

  • Digital Gold Detectors

A rather advanced form of output where the model and build of detector assigns a number to the precious metal and non-precious metallic compounds where the readings close to the largest possible number indicate the purest metals underneath the surface whereas the numbers in lower possible ranges mean irrelevant metallic compounds.

  • Sound Based Gold Detectors

The type of detectors which make a beeping sound when metal is detected within its range and no other relevant information is provided whether the metal is in which category or its distance from the surface etc. However, the sound is louder in case of proximity and fades when the distance increases, which is vague but still effective in some situations. This technology can be seen in handheld security detectors as well as walk through gates.

  • 3D Graphics Based Gold Detectors

These gold detectors present the information in the form of colorful graphical representations where each of the colors means a specific metal or metallic compound in terms of the object’s purity. 

Huge Gold Nugget Found!

Recently, an Australian treasure hunter found a ginormous gold nugget weighing 49 ounces and grossing up to $49,000 in value! Yes, treasure hunting is a thing and gold metal detectors facilitate hunting them out from deep down the Earth. 

How Gold Detectors Work

Basically, gold detectors receive direct current from the battery, convert it into alternating current, which creates a magnetic field. This magnetic field emits electronic waves (eddy current) into the ground which when absorbed by a metallic object, create its own magnetic field. This new magnetic field distorts the earlier magnetic field and sends current to the receiving coil, which shows the output of positive metal detection.

 

Frequency of Gold Detectors

Frequency means the number of electronic waves a detector throws into the ground. Each frequency range is sensitive to a different type of compound and depending on the model and brand, these frequencies can vary. However a general rule is, that higher frequency results in decreased depth, but it becomes more sensitive and detects when smaller objects. 

Elements of Gold Detectors

  1. Coil

The circular base of the metal detector having the arrangement of wires in it in which the current flows and generates a magnetic field is called coil.

  1. Shaft

The long structure giving support to the coil and including a grip to hold the detector which makes it easier to carry and move the equipment around easily. 

  1. Control Unit

The device attached to the coil which receives input from the operator and gives output about the object is the control unit. 

Technologies in Coil

  1. DD Coil

An advanced form of the coil where the wiring within the apparatus is divided into two semicircles making a D and inverted D connected. It helps differentiate the ferrous and non-ferrous compounds within the ground which makes it easier to distinguish between gold and trash.

  1. Mono Coil

A simpler coil having wires arranged in its circumference where the circle is tightly wound covering more depth than DD coil but has the disadvantage that it does not discriminate between ferrous and non-ferrous compounds.
