VLF Technology VLF Metal Detectors HowStuffWorks

The metal detector can determine approximately how deep the object is buried based on the strength of the magnetic field it generates. The closer to the surface an object is, the stronger the magnetic field picked up by the receiver coil and the stronger the electric current generated. The farther below the surface, the weaker the field. Beyond a certain depth, the object's field is so weak at

VLF Phase Shifting HowStuffWorks

Since most metals vary in both inductance and resistance, a VLF metal detector examines the amount of phase shift, using a pair of electronic circuits called phase demodulators, and compares it with the average for a particular type of metal. The detector then notifies you with an audible tone or visual indicator as to what range of metals the object is likely to be in. Many metal detectors

PI Technology PI Metal Detectors HowStuffWorks

PI-based detectors are not very good at discrimination because the reflected pulse length of various metals are not easily separated. However, they are useful in many situations in which VLF-based metal detectors would have difficulty, such as in areas that have highly conductive material in the soil or general environment. A good example of

Anatomy of a Metal Detector HowStuffWorks

Operating a metal detector is simple. Once you turn the unit on, you move slowly over the area you wish to search. In most cases, you sweep the coil (search head) back and forth over the ground in front of you. When you pass it over a target object, an audible signal occurs. More advanced metal detectors provide displays that pinpoint the type of metal it has detected and how deep in the

7 Best VLF Metal Detectors! (+How they Actually Work)

VLF vs PI Metal Detectors What’s the difference? Pulse induction (PI) is a more sophisticated type of detecting technology Indeed, it involves a high voltage pulse that is sent into the ground. The PI technology does not get affected by ground minerals, unlike VLF detectors That’s they are the Best choice when it comes to gold prospecting! Below a table that gather the main

Unlike pulse induction (PI) metal detectors, VLF metal detectors tend to offer better discrimination against trashy targets and many VLF machines now give the option of configuring tone frequencies, setting separation speeds, and switching between frequencies. However, target depth tends to be a limitation in VLF machines compared to PI machines. PI machines will punch deeper in the ground but

In a VLF metal detector, there are two distinct coils: Transmitter coil- This is the outer coil loop. Within it is a coil of wire. Electricity is sent along this wire, first in one direction and then in the other, thousands of times each second. The number of times that the current's direction switches each second establishes the frequency of the unit. For example, some models have a frequency
