Information about metal detectors and gold looking at Gold detectors frequencies and sensitivity to get rid of jamming and excellence among various metal disks or coil used in the detection.
Discrimination
Selective disclosure allows discrimination by eliminating all ferrous metals during the search (iron, steel, nails, capsules, etc.).Then the machine will only look for non-ferrous metal objects.
Contrary to what one might think, is not discrimination on a disclosure undertaking to discover all the valuable parts, small jewelry that can be eliminated by a very high distinction. We recommend that you use the discrimination with precautions to not pass side small objects but interesting all the same (for example the distinction that detector is set to remove the Tin from the rejection of l can also be a coin or gold ring).
About the performance of the machine is reduced approximately 20%. We note also that discrimination in small Nonferrous object under object of greater surface will not be detected.
The situation remains “all metals” stronger position in most cases.
Frequency
The working frequency of the detector (can vary from about 3 kHz to 20 kHz depending on the equipment). Detectors are often used by prospectors are sensor low frequency (VLF).
White has built example of devices that operate at a frequency of 6 kHz and at the same time providing good sensitivity and distinguish the good in any environment.
Sensitivity
The sensitivity is to modify the device in order to eliminate such Crackle c noise or spitting. These annoying references due to different types of soil.
Detection coil
End of the detector in the roll which was able to send signals to the device while scanning for surfaces to prospecting. Its size usually 20 centimeters in diameter but must be interchangeable disks to target (small drives for greater accuracy) and large disks for more in-depth research.
Means “GP” disc drive “great depth”.
Effects of Earth
Effects of soil are interventions caused by different types of soil by virtue of those compositions. This generates the wrong signals.
Is soil minerals in the formation of oxides contained therein on the opaque screen blocking the movement of the waves. The new generation of aircraft equipped with a Compensator is now on the ground to eliminate these genes interfere. It is noticed better prepared to mitigate the effects of soil stability perfect both in the air and on the ground with the disk. This setting must be changed regularly as transactions run on the best performance.
These settings can be automatic (based on the analysis made by the received signal processor) or manual (sliding potentiometer, current system remains the best).
