Searching for a good metal detector isn’t an easy job. There are thousands of different types of metal detectors are in the market. But now you have to don’t worry, In this post, I’m going to describe all types of metal detectors for you.
Let’s without doing further ado, jump into the details of metal detector.
A metal detector was invented by Alexander graham bell in 1881. in early days metal detector was work on the basis of magnetism and electricity. But nowadays due to upgrade many different types of metal detectors are available in the market. In the below section, I added the best metal detector for entry-level, Relic hunting, saltwater, gold, freshwater, and kids.
What are the metal detectors?
Metal detectors conjure varied images to many people. To some, metal detectors remind them of the buzzing lights at airport security. Others associate metal detectors with treasure hunting. Some think of handheld scanners used in crowded events such as concerts or sports events.
All of these applications are true. Metal detectors are widely used for different purposes. But what are metal detectors in the first place? The following is a dictionary definition of metal detector:
– A device that senses the presence of metal,
Quite obviously, metal detectors are used to detect metal. These devices are able to do this through the use of electromagnetic induction.
There are several types of metal detectors. These devices are classified mostly by their size, shape, and purpose. There are the security metal detectors found mostly in airports and other places that require security checks. These metal detectors are stationary and are used to find potentially dangerous items such as guns, explosives, and other weapons so that they will not be brought into restricted areas.
There are also industrial metal detectors. These devices are used mainly in the production process for quality control. These detectors help ensure that products that are shipped do not contain sharp objects like pins and nails. They also measure overall metal content.
Another type of metal detector is the handheld devices used mainly for exploration, hobby searching, and de-mining in the military. Through the use of electromagnetic induction, these metal detectors can identify metal buried underground or in the water. Because these metal detectors are very portable, some hobbyists bring them to explorations and vacations to find relics and treasures such as old coins.
Walkthrough Metal Detectors
Walkthrough metal detectors are very useful for places that require security checks such as airports, schools, prisons, factories, high-risk government buildings, hotels among others. Walkthrough metal detectors are installed in these places mainly to detect the presence of firearms, knives, and other deadly weapons. These detectors can also detect other contraband items that individuals may try to sneak in or out of facilities.
Walkthrough metal detectors scan the entire body to detect weapons hidden in a person’s body. Today’s walk through metal detectors is designed to detect weapons and other dangerous devices. These metal detectors also detect razor blades and microchips. When a questionable item is detected, the detector produces an alarm signal, which can either be audible or visible or both.
When it comes to detection, most walkthrough metal detectors models are expected to provide superb discrimination, excellent target selection, high throughput, low false alarm rate, uniform detection within the entire archway, and a bi-directional system.
There are also some models that are designed for metal-free security applications. They usually come with one-eighth of an inch thick aluminum shielding panels, easy calibration for the program, and sensitivity settings.
Aside from the standard walkthrough metal detectors, there are manufacturers that specialize in portable walk-through metal detectors. With prices ranging from $3000 to $6000, these portable walkthrough metal detectors can be installed and operated easily since they are very compact and lightweight. Such devices are particularly useful in big crowd events such as concerts, sports games, tradeshows, exhibits, fairs, international conventions, and meetings, among others.
To maximize the benefits of the equipment, however, the installation of walkthrough metal detectors should be carefully aligned with the security and detection program of a facility.
For instance, metal detectors will not be of many benefits if the security personnel is not trained to operate these devices properly. They should also know the protocols when dealing with people detected to carry firearms or other questionable items.
With the increased concern for security due to the ongoing threats of terrorism, people have become accustomed to passing through walkthrough metal detectors whenever they enter buildings. Although there is much debate regarding privacy and even health-issues raised against the use of metal detectors, the importance of contraband detection devices such as the walkthrough metal detectors can never be undermined.
Fortunately, concerned government institutions such as America’s National Institute of Justice (NIJ) are not lacking in initiatives on setting standards for the proper use of metal detectors in weapons detection. As early as June 1974, the National Institute of Law Enforcement and Criminal Justice (NILECJ) — the predecessor of NIJ – has already come out with the NILECJ Standard-0601.00, Walk-Through Metal Detectors for Use in Weapons Detection, in June 1974. This standard would undergo revisions in later years with additional inputs from the public safety community and the manufacturers of metal detectors.
The latest standard, NIJ Standard-0601.02, Walk-Through Metal Detectors for Use in Concealed Weapon and Contraband Detection, already includes improvements in detection performance as well as new requirements for system performance, including operator interface and/or controls, more realistic test objects, environmental tolerance, electromagnetic compatibility, quality control and assurance, safety, and operator instructional and technical repair documentation.
These new standards and requirements are envisioned to further improve the technology as well as the use of walkthrough metal detectors for detecting concealed weapons and contrabands.

Garrett AT-Pro Metal Detector Review
Garrett AT-Pro is one of the most selling metal detectors from Garrett. This metal detector is the most versatile metal detector that you ever saw. using this you can not only search on a ground-level even you can search on pond, river, or in the ocean. It’s fully waterproof and can be submersible up to 10 feet. Check out some best features of Garrett AT-Pro Metal Detector
Operating frequency – Garrett At pro is working on 15khz frequency. Which is quite high compare to other well-known metal detectors. But it’s little less compare to the AT-pro gold version ( i.e, 18khz).
Audio Mode – Two types of audio mode is available in this metal detector one is normal mode other one is the pro model. Where is the pro mode you can customize pretty much everything according to your needs, knowledge, and experience.
Iron Audio – Iron audio is another special feature which generally not found in an entry-level metal detector. In this mode, you can set the discrimination from 0-40. Having a higher discrimination value is always helpful when you want to skip nails or junks.
Ground Balance – Ground balance is another important aspect of metal detection. When you are using this tool on a mineralized soil or you are using this on saltwater. In both cases ground balance is important. You can set ground balance automatically as well as manually. Ground balancing helps you to ignore signals that come from the soil due to the presence of iron and salt.
Features that I like –
- Fully waterproof as well as submersible.
- Can set up ground balance automatically as well as manually
- Available proportional audio as well as iron audio.
- 2 Years warranty.
Fisher F75 Review
If you are searching for a mid-range metal detector then you should go with a fisher F75 metal detector. Fisher is one of the old and renowned brands among the metal detector industry. It has an operating frequency of 13 kHz which is quite good compare to other mid-range metal detectors but still lower than Garrett pro. This metal detector is perfect if you are hunting for the coin, relic, or jewelry. Due to low frequency, you can find large gold jewelry but you can find small gold nuggets or flakes.
Let’s check all the features of Fisher F75 metal detectors
Operating Frequency – As I said earlier this metal detector working frequency is 13khz. So this is the perfect tool to find coins, relics, and jewelry.
Numeric target ID – Most of the mid-range metal detectors come with numerical target ID. Numerical target ID is nothing but a range from 0-99 where it shows any number according to metal connectivity.
Iron objects – 4-12
US nickels – Around 30
Aluminum pull-tab – 35-55
Clad dime – around 70
US quarter – around 80
US silver Eagle – Around 91
Search Mode – Fisher F75 has 3 different search modes. Those are motion all-metal, static all metal and discrimination mode.
Ground balancing – Ground balancing can be done by manually or automatically. Ground balancing is very important when you are searching on sea beach or ocean where iron and salt already in the ground. Ground balancing just neglects those.
What I like in Fisher F75 metal detector
- 0-99 Numerical target ID
- Super light weight and easy to carry
- It’s waterproof. But the control box is not waterproof. So you cant submerge the control box in the water.
- Best mid range metal detector to find relic, coin and jewelry.
- it also allows you to save your previous search session

Metal detectors are used to search for archaeological finds
Other people, on the other hand, find more practical day-today uses for their metal detectors. They use it to find septic tanks, missing tools, equipment, metal pipes, and other buried items. Others use it to find missing jewelry and other valuables while some waterproof detectors could even help find a ring that was lost in the lake or river.
From these applications, we can deduce five basic types of metal detectors: General Purpose-Coin/Relic/Treasure; Gold Prospecting; Underwater & Salt Beach; Cache Hunting/Deep Searching; and Industrial & Security.
Although manufacturers may design their metal detectors differently, most devices would have the same basic components. There are four key components that metal detectors must-have, namely:
• Control box – this enclosure is placed at the top of the metal detector and contains the ‘brains’ of the metal detector- the circuitry, controls, speaker, batteries, and microprocessor. Often there is a display unit with a jack for headphones built into the control box.
• Stabilizer- this optional component is usually an arm brace that keeps the unit steady as you sweep the metal detector back and forth.
