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.
