Types of Metal Detectors That You Need To Know

If you are looking for a good way to know if a particular person is carrying any weapon with him/her, then the metal detectors can be of great help for you. So, what is a metal detector? Well, It is a device which is used to find metallic pieces. There are different types of detectors which you can use to find gold or any other metals. The most sought after ones are the gold metal detectors. Here are some of the types of metal detectors

VLF – Very Low Frequency

As the name suggests, these type of detectors are the most commonly used ones. With the VLF detector, several types of metals can be detected, and it uses two rounds of wire. The curl of wire on the outside is the transmitter while that within is the beneficiary. The transmitter discharges a low recurrence magnetic field which is in charge of the transmission. The recipient gets the flag and translates it as indicated by the magnetic heartbeat. Since this indicator can be utilized to recognize metals thus, it falls in the class of gold metal identifiers.

Pulse Induction detector

This type of metal detector uses a magnetic field to generate a pulse. Unlike the VLF detectors, it consists of only one coil. This is the most common type of detector which is used by the treasure hunters because of its ease of access. When a metal which is present underground reflects the signal, the pulse inductor switches the mode and listens for the source of the reflected sound and hence determines the position of the same.

Beat Frequency Oscillation

A metal detector which uses this technology is the simplest and the most inexpensive metal detector. They are mostly used by beginners because of their ease of access. Just like a VLF detector, this also uses two set of coils for the effective detection of the metals. An oscillator is used to create a constant signal at a particular frequency, and that is emitted by one set of coils. On the other hand, the second coil is responsible for the interference of this frequency and causes a change in the one of the audio.

This type of detector uses the technology of VLF detectors but lacks the fine tuning as well as the filtering ability of VLF detectors. Thus, the beat frequency oscillation detectors are less accurate compared to the VLF detectors.

Hence, keeping the above description in mind, you can very easily choose the type of metal detector required for your work. For example, if you are on a treasure hunt, you should use the pulse induction detector. On the other hand, if you want to look for gold, then VLF detectors will be the best one for you So, depending on your need, you are now free to choose the type of metal detector you want
