Complete Buying Guide to the Best Metal Detector
A metal detector is a tool that detects presence of metal. It is an electronic instrument that helps find metal in objects or buried metal objects.
It typically consists of a handheld component and a sensor probe swept over the ground. If metal is detected, a needle on the indicator moves or there is a change in tone in the earphones.
Most devices also indicate the distance of the metal. The nearer it is, the higher the tome or the movement of the needle.
There are also stationary types or “walk through” detectors that can conceal metal objects in one’s body or things. These are used for security screening in public places, courthouses or prisons. The simplest one uses an oscillator that produces alternate current passing through a coil that produces alternate magnetic field.
The first metal detectors were created in the 1960s for industrial applications. They were used in detecting land mines, weapons in airport, treasure hunting, archaeology and geophysics.
They were later developed to be used in various industries. You can find them being used to detect reinforcing steel in pipes, wires or concrete buried in floors and walls; or to detect foreign objects in food.
Today, they are used in various countries and purposes. They are useful in archaeology, civil engineering or as a hobby and in security.
This complete guide will tell you the basics of metal detectors, its types and your options in which to buy. You can also learn about the important considerations in buying a metal detector.
Types of Metal Detectors and How They Work
There are several types of metal detector, but the most widely used is the VLF, or the Very Low Frequency type.
A typical one should be lightweight with a control box, stabilizer, shaft and coils. In order to understand how metal detectors work, you have to learn what these components are for.
To make it simple, most metal detectors work based on the laws of electromagnetism. The instrument uses battery to produce a penetrating magnetic field in the ground. Metallic objects will be charged with magnetism below the ground and sends a signal to the detector that alerts the user.
Depending on the unit, it can tell the type of metal found and how deep it is. Most units can trace up to 12 inches below the ground but there are others that can detect at deeper levels. These are the common types of metal detectors:
Beat Frequency Oscillation (BFO)
BFO is the most basic metal detector technology that uses Beat Frequency Oscillation. It uses two coils of wire, one large and one small. The larger one acts as the search head or search coil that locates the metal. The small coil is found in the control box.
The coils are connected to the oscillator that creates large numbers of electronic pulses of current every second. Frequency is quite offset between these coils.
As electronic pulses pass through the coils, they generate radio waves picked up by a tiny receiver inside the control box. This produces audible tones based on the difference on frequencies between the coils.
When the larger coil detects a metal, the current that flows through it creates a magnetic field around the metal. This interferes with the radio waves’ frequency that produces the audible tone. BFO uses the easiest and least expensive technology.
Pulse Induction (PI)
Pulse Induction technology uses a single coil as both receiver and transmitter. Some use two or three coil series.
PI sends electricity passing through the coil, causing magnetism. When the bursts of electricity end, the magnetic field reverses polarity and collapses, producing sharp electric spike. The spike causes another current to run through the coil.
This process is repeated until the detector is given different current reports on the type of metal sensed. If the detector is over a metal, the bursts produce opposite magnetic field in the object. When the bursts stop, it causes a reflected pulse.
The metal’s magnetic field makes it longer for the pulse to disappear. It works just how like echoes, which makes the PI type not so good in differentiating between metal types. However, they do well in areas with salt water and metals.
Very Low Frequency (VLF)
Also known as Induction Balance, VLF technology is more widely used among the different types of metal detectors. This system uses two coils, one acting as transmitter that swiftly gives off electricity. The other acts as the receiver and antenna to pick-up and increase frequencies from metals.
A current passes through the coil, creating an electromagnetic field. The magnetic field is pushed down into the ground and pulled back out. As it goes back and forth, it reacts with any conductive objects and generates its own magnetic fields.
The polarity of the metal’s magnetic field is the opposite of the magnetic field of the transmitter coil.
VLF type of detectors can distinguish metal types through phase shifting. Phase shift is the variance in timing of the frequency of the metal and the transmitter coil.
Highly conductive metal has longer phase shift, as its magnetic field takes longer to alter. On the other hand, less conductive objects’ magnetic field takes quicker to alter due to the smaller phase shift. VLF detectors are excellent in identifying types of metal but are more expensive than the others.
Components of Metal Detectors
Regardless of type, metal detectors include the following components:
Stabilizer: it keeps the detector steady as you sweep it over the ground. It is usually a brace that add comfort in supporting the detector’s weight. Most manufacturers include stabilizers as standard component of metal detectors though there are some that offer them as optional equipment.
Control Box: the “brains” of the metal detector, where the controls, circuitry, speaker, microprocessor and batteries are found. Some models contain jacks for headphones.
Shaft: The shaft is the one that connects the search coil to the control box. Detectors vary in the design of the shaft. Some are shaped like a flat S, which places the LCD/meters, and control in easy adjustment and viewing. Some are adjustable so users can set the right distance according to their height.
Search Coil: the part responsible for sensing the metal. It is also called search head, antenna or loop.
Audio Jack: this is used for connecting the headphones. Headphones may or may not be found in detectors, but having them eliminates background noise so users can focus on the tones that tell the presence of metals. Headphones may also extend battery life for less current is required and operating time is significantly increased as well.

Choosing the Best Metal Detector
The best metal detector is one that works for you.
You might just be starting out with the hobby or you are already an experienced hunter. For newbie, you might consider other items such as shovel or bag to carry your discoveries.
If you are serious about getting a metal detector, it takes careful researching as opposed to getting the advice of an expert who is likely to have developed preference for a specific model. These are the things you should consider before attempting to buy one:
Frequency of Use
Determine how often you intend to use the instrument. Perhaps there is no need to buy an expensive model if you are out to go for hunting only on weekends or when time permits.
You can go for simpler models with not so advanced features that may complicate the process or add to the price. However, if you have decided on making metal detecting a part of your life, you might as well invest on something that is packed with features and a price you can afford.
Type of Usage
If you are thinking of buying a metal detector that the whole family can use, choose one that has adjustable components. This makes it possible for the device to be used even by children.
You can also go for something that is lightweight so everyone can enjoy using it even for longer periods without straining the arm or back. The height is also an important consideration. It is not smart to use a detector that requires a lot of bending just to search for a coin.
As mentioned, metal detecting can be challenging for particular type of soil. You can go for detectors with ground balancing. This allows you to search in soils with higher concentration. If you want to search on beaches, look for models that can be adjusted to use at different areas so you don’t have to buy something expensive like specialized salt water detectors.
Metal detecting, like other outdoor activities, involves different levels of experience. Some people even get assistance from trainers before they claim themselves experienced hunters.
The good news is, there is a metal detector for every level of experience. However, simple and sophisticated detectors tend to be more expensive. Experienced hobbyists do not need to buy specialized detectors but inexperienced ones need the help they can get.
The Item to Search for
You have to be careful in picking the type of detector to buy especially if you intend to work on land mines or the like.
Some people who are into treasure hunting are knowledgeable about a particular treasure. There are metal detectors designed for this task based on the composition of the treasure.
Some models may not determine the metallic composition of the items found in mines. Wrong purchase could lead to waste of time and money.
It is important to figure out how you plan to use the device and in this regard, the manufacturer is the best source of information before making any purchase.
Models that are more expensive can guarantee accuracy in metal detecting, but this is not always the case. This is where knowledge in metal detecting proves to be very useful.
You might end up with a flashy detector with poor functionality. Looks is not a priority in buying a metal detector. In every product, what you need to consider the value for money you are getting.
Take the above considerations carefully.
Metal detecting is not a new craft.
In fact, metal detectors have been developed since the 19th century. It only gained prominence after World War II with the intent of clearing mines. Since then, it developed and sustained by supply and demand.
Treasure hunters seek metal detectors that could perform better while manufacturers invested more money on research. This has resulted in innovations year after year.
The market is now very competitive, while consumers benefit from having as many options. However, this could also lead to confusion but with the wealth of information found online, there is no reason to settle for anything less than the best metal detector.
Again, patience and research are enough for you to get your money’s worth. While it is challenging to buy a new metal detector, the joy of being able to own one and enjoy the hobby is worth the initial difficulty.
