The 10 Best Metal Detectors Reviewed

A metal detector is a tool that detects the presence of metal in a given area. Because these instruments are sensitive to the presence of all metal, they can be useful to detect metal-containing objects that are either imbedded within some other material or underground. You have probably seen someone waving one over the sand at a beach and undoubtedly, you’ve had to pass through a metal detector at the airport, courthouse, or sports arena.

A Mini Guide To Metal Detectors and Their Uses

As the scientific community studied and explored electricity and its manipulation, it became feasible to use predictable electrical activity to detect the presence of ore. This was useful in various settings—from the mining industry to the medical detection of bullets lodged within a body. Modern metal detection has varied applications for personal and commercial/industrial use. New metal detectors can even detect bombs, a widely sought after application in travel and security.

The basic mechanism by which metal detectors work is simple. An alternating magnetic field is created by passing an alternating current through a coil. If conductive metal is nearby, it produces eddy currents, and a resulting magnetic field, in the metal. A second coil measures this change in the magnetic field caused by the metal object can be detected and measured. Numerous refinements to the metal detector have been made over time. An alternate design employed two coils in electrical balance. When there was imbalance between the two, it was caused by the presence of metal nearby. It was possible to even differentiate between types of metals as each specific metal had a unique response to the current, however this assessment was difficult to make and sometimes lacked in sensitivity. Another method momentarily magnetised the ground with a powerful, quick current. The surrounding area would return to zero voltage at a given rate. However, if metal was present, a small current would form in the metal and the time to return to zero voltage would be increased. This method overcame several issues with earlier models. Today, there are a variety of different metal detection methods that can optimize the search for metal in a number of different scenarios.

Metal detectors are used in various settings. For example, industrial food manufacturers may use some sort of metal detection to prevent metal pieces from machines to be passed through in food to the consumer. In fact, this precaution is taken by many industries, including textiles, plastics, packaging, and lumber sectors. Metal detectors are also widely in the practice and field of archaeology. They can give researchers valuable clues and markers about what exists below ground. However, archaeologists underscore the need for preserving and surveying the area when trying to unearth a found object. A popular use for metal detectors is to provide security screening, usually in a place of gathering. The ubiquitous use of metal detectors in airports began after a series of hijackings in the 70’s. Today’s models are able to determine the approximate height or relative positon of the metal object to aid in surveillance. Lastly, people purchase metal detectors as a hobby tool. Some aim to find gold and other valuable metals, others seek coins and other discarded or lost valuables or relics.


Different Types of Metal Detectors

As mentioned earlier, the original metal detector had a simple configuration. From there, the machine has taken on various methods of action, forms, and applications. The beat frequency oscillation detector runs on the basic principle of the first metal detector, where the change in magnetic field caused by the effect of an induced magnetic field on a metal is measured. This is a common type, but also considered to be the weakest. They are able to detect metal up to two feet away, as indicated by a change in audible tone.

Very low-frequency detectors are popular because they are accurate and sensitive. There are two coils: a transmitter coil that emits current and a second receiving and amplifying coil. The first creates a well-defined magnetic field. A nearby metal disrupts this magnetic field and creates interference, which is detected and amplified by the second coil. This type of metal detector is useful in differentiating metals, which can signal the difference between treasure and junk.

A pulse induction metal detector is commonly used in security wands and at checkpoints. It is an expensive method, so there is some limitation to its prevalence. It works by creating a short, powerful pulse of current. The current, through a process similar to echolocation, passes through an area and is able to capture the relative feedback of materials nearby. This type of metal detector is not good at differentiating between types of metal.

Industrial metal detectors are usually built in a door-frame shape. They create an electromagnetic field and study the disruption to it as a person walks through. Because they are highly sensitive to metals, it is routinely required that one removes all metal on their body before passing through the detector to avoid nonsense false positives.


What to Consider Before Buying

​Today’s metal detectors are designed for specific tasks, therefore it is important to ascertain what the metal detector would be used for and in what setting, before selecting a model. While there are many available brands and models available on the market today, some types of metal detectors may not be practical. There are metal detectors that are used commercially (with no real means of personal use) or others that are prohibitively expensive. You must be able to strike a balance between cost and quality; a poorly functioning metal detector can miss valuable material or give off false positives that create unnecessary work.

Further, it is important to find a model that you are comfortable holding for long stretches at a time. Even light objects can feel burdensome after hours holding them outside. Look for one that is lightweight and comes with a shoulder strap or armband. Lastly, the operation of the machine should be simple (or at your comfort level), without lengthy calibration that may inadvertently compromise the quality of the search.
