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 Display of Gold Detectors Tell

/in /by

When it comes to mechanical equipment collecting some kind of input from the environment, the method of their display of output also becomes very important. The quality, the material as well as the accuracy of output generated by metal detectors can predict their value to the users because sufficient information is provided in an understandable format becomes the key of the effectiveness of the equipment in question. Following are the available methods of display of gold detectors which can be found from beginner to professional level equipment and what exactly they can tell. 

Analog Gold Detectors

The most backward kind of option in some of the lighter variants and older models of gold detectors available include an analog display. It shares the least amount of information regarding the detection and is the least effective among all types. Basically, a needle is present in the middle of the lowest end of the scale. The scale may have divisions in numeric form or basic high low, where low determines the signals from far away or smaller objects whereas high or larger number characterizes strong signal from a relatively closer location or larger object. The needle deflects according to the magnetic field received by the recipient coil, if strong then towards the stronger pole and if less then towards the weakest pole of the circular or semi-circular scale.

Digital Gold Detectors

These are relatively modern display system having an LED (Light Emitting Diode) display where the system assigns numbers to certain metallic components to make sure it can clearly distinguish between ferrous and non-ferrous compounds. The numbers assigned to each group can be different and is usually in ranges as well where a certain range would determine the purest form of gold, whereas on the opposite end, the range would determine the pure iron or ferrous alloys. These digital displays are more practical as compared to analog and are seen very frequently in intermediate, advanced and deep seeking gold detectors. 

3D Graphical Gold Detectors

The most advanced form of display in gold detectors is when the display comprised of an LED backlit technology and the screen is able to show colorful graphs and can summarize the shape and size of the prospective object found or detected underground just by scanning it from the top. This output method used a different color to classify different type of metal and once again the colors can vary from model to model. 

Role of Frequency in Gold Detectors 2019

What Frequency means in Gold detectors

Frequency means how much waves are hitting the ground emitted by the gold detector. The magnetic waves formed by a change in alternating current in the coil of the detector generates electronic waves which hit the ground and colliding with the magnetic field of another metallic object, receives the input electronic waves generating detection output.

How it is measured

It is measured in KiloHertz (KHz), which means if the frequency of your detector is, suppose a 100KHz, then 100,000 waves are hitting the ground.

Relationship of Frequency with Depth

Frequency and Depth have an inverse relationship which means if the frequency of waves hitting the ground increases, they will penetrate the ground in lesser depth. But if a lesser number of powerful waves are emitted, they will penetrate the ground comparatively deeper. 

Relationship of Frequency with Sensitivity

In contrast, frequency and sensitivity have a direct relationship, meaning if the frequency of the number of waves hitting the ground increases, it will be efficient towards detecting minor sizes of the metallic objects, increasing the sensitivity of the equipment. more And if a lesser number of waves are hitting the ground it will be more difficult to detect smaller sized object ignoring them completely or partially, resulting in less sensitivity of the equipment. 

What High Frequency means

In sum, if the gold detectors are working on high frequency of waves, they will become unable to detect objects in more depth but the sensitivity will increase as no matter how less the depth is, nothing will be ignored within that range.

What Low Frequency means

Low frequency would mean lesser number of waves hitting the ground, so they would be more powerful and go deeper into the layers of the Earth’s surface. However, it will compromise the sensitivity of the equipment as it can ignore the relatively smaller chunks of metallic objects. 

Choosing the right frequency range detectors

Depending upon your specific needs, you can choose which detectors suit you the most. Using very high frequency can cause noise in output as the equipment would become sensitive to even the metallic particles in the sand which are irrelevant in terms of their value. But using extremely low frequencies would result in ignoring valuable pieces of metal. So choosing just the right amount of frequency range by using the help of technical specialists in our firm is highly recommended to make sure you buy the right equipment.
