Purchasing the right metal detector can be a tough decision particularly for beginners. This is because there are hundreds of models currently on the market. Moreover, there are many metal detector review sites offering contrasting views and tips. Ensure you find the best metal detector. You need to carefully consider your selection. You also need to know the different components that make a metal detector.
The components of a metal detector are the ones that make it possible to carry out its job. It is necessary to understand the various types of technology, which are associated with the metal detectors. A typical detector is one that is lightweight and has some parts. They include:
This part is used to maintain the metal detector steady. Remember that a detector is used by sweeping it back and forth.
This is a part that contains all controls, circuitry, batteries, speaker, and microprocessors for a metal detector.
It connects the box to a coil. It is usually adjustable so that people can easily set it at comfortable levels for their height.
This is one of the important aspects of every metal detector. In fact, it is this part that senses whether there is a metal there. It is also known as “antenna,” “loop,” or “search head” by some people.
Some units have a means of connecting headphones to a metal detector. Others have a control box below the display unit and shaft above it.
The process of operating a metal detector is quite easy. What you need is turning it on and then slowly move it over an area where you need to search. In most instances, you will move it forward or backward over a target object. It will then produce an audible signal. Nowadays, there are advanced models that provide the display, which pinpoints the metal type they have detected.
The following are types of technologies that are used in metal detectors:
VLF – Very Low Frequency
This is a very popular type that is available on the market. It is mainly made of two coils: receiver coil and transmitter coil.
Unlike VLF metal detectors, the PI system uses the single coil as both the receiver and transmitter. Some models have two or three coils working together.
Beat Frequency Oscillation
This is a basic method of detecting a metal. In this systems, there are two coils where one is a head and the other a coil that is located inside the control box.
