Use of different type of metal detectors in the market

A metal detector is an electronic device that uses electromagnetic induction to detect metal. You can find them in use at airports and malls, in mining and archaeology, and prospecting or treasure hunting. For whichever use you may need a metal detector for, you will have to make sure that the device is the right kind so that it will not hinder you from doing the job well. The following are choosing a metal detector tips.

Metal detectors in the market

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.

VLF - Very Low Frequency

As the name suggests, these types 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 coil of wire on the outside is the transmitter while that on the inside is the receiver. The transmitter emits a low-frequency magnetic field which is responsible for the transmission. The receiver receives the signal and interprets it according to the magnetic pulse. This detector is used to detect metals hence it falls in the category of gold metal detectors. 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 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 interference of this frequency and causes a change in the tone 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.


Uses of metal detectors

Metal detecting can be truly fun and exciting particularly if you discovered the best tricks to make the most out of your metal detector. But to begin with, you need to find the best metal detector that suits you. If you are only getting started on your metal detecting activity, choose the metal detectors for the amateur since it is easy to use and not complicated, which is what you primarily need. If you have stumbled upon the metal detector that truly suits you, then off you go on your metal hunting trip. However, even if you possess the metal detecting device, you also need to know where to find it.


Dry sand can become one of the best search areas with your metal detector- Beaches that are frequently visited by people would be best searched at around 5pm onwards, when almost all the people have gone home and the beach is nearly deserted by people that may hinder you from totally scouring the entire beach area. Shallow waters more often than not provide good outputs. The reason is that people stay more in the shallow part of the beach since they can actively play there while guarding their children, and the water can shrink the fingers, letting their valuables fall into the sandy water where things are truly hard to find.


If the beach is unavailable in your place, running some background research can always help you in trying to figure out historical spots near you where you can begin your metal hunting activities. There are a lot of success stories where an avid treasure hunter has been scouring a particular historical area for years and have discovered very expensive artifacts which was auctioned and sold for a hefty sum.


Lately, there have been quite a number of treasure hunts that became successful with the use of metal detectors. Recently some old coins were found in Somerset, England, by a novice treasure hunter who was just scouring the area with the use of a novice detector.
