10 Popular Metal Detector Manufacturers

There are many manufacturers operating in the metal detector market. Their products differ significantly in characteristics and capabilities, and therefore in prices.

Garrett

The American company Garrett entered the metal detector market back in the 60s of the last century. Today the company has 3 main lines for civilians:

1. for newbies;
2. for intermediate level;
3. professional models.
4. The best hair straightener comb - TOP 25 rating
5. In general, the company produces from the simplest ground and deep metal detectors to arched ones. Many Garrett models are used in banks, airports, and law enforcement agencies. There are products designed to search for mines, other explosive devices, and ammunition.
6. Macro

The company began producing metal detectors in 1986 in Turkey. For a long time, Marko METAL DETECTORS has improved its models and strived to produce the highest quality products and introduced innovative solutions. Most of the products are suitable for searching for objects in the harshest conditions.

Nokta&Makro

The company appeared in 2018 as a result of the merger of 2 Turkish brands “Nokta” and “Makro”. Today, the company's products are represented in more than 150 countries.

The trademark “Nokta METAL DETECTORS” appeared in 2001.In just a few years of operation, the company has won the recognition of buyers, both professional and amateur. The company's line included deep, ground metal detectors for detecting jewelry and coins. There were many proposals for commercial organizations.

The Russian company RGK began its activities in 2006. In a relatively short period of time, it has gained a reputation as a reliable manufacturer. The company not only produces metal detectors, but also specializes in the production of measuring and geodetic instruments for the construction industry.

Minelab

In 1985, metal detector production began in Australia. The Minelab company focuses on the ordinary consumer who searches for treasures for his own pleasure. The company also produces metal detectors for military and humanitarian (mine clearance) needs. It was here that the first model of the dual-frequency detector was released in 1989.

The company has a huge portfolio of developments, since most of the income to this day goes to innovative development. Consumer services operate in most countries around the world. All products must be certified and approved by ISO 9001 standards.

In 2008, Minelab became part of the Codan Group of Companies, which develops and produces equipment for satellite communications and high-frequency radio.

Teknetics

The company appeared back in 1983. In 1989, it became part of the First Texas Products group. The company’s specialists managed to make a real breakthrough in the industry back in the 2000s of the last century. The legendary T2 metal detector has appeared on the market. The line of these detectors is popular to this day, and many models have won professional competitions.

KIP-PROFIT

The Russian company KIP-PROFIT became known to consumers thanks to the release of the KR-30 Iskra. This is a budget ground metal detector, easy to use and reliable. Can search for a specific type of metal. The ergonomic body and optimal weight allow the product to be used even by children.

Quest

The American manufacturer Quest was created by the most ordinary lover of searching for artifacts. Several years of hard work have yielded serious results. Now the company produces the most modern detectors at affordable prices. Every Quest model is equipped with the latest features and reliability. Warranty support is available in almost every country in the world.

MetaScan

The Russian company MetaScan can be called the country's leading manufacturer. The company has been on the market for more than 15 years and produces a wide range of metal detectors:

underwater;

arched;

inspection;

ground;

to search for coins and precious metals.

The company boasts a full cycle and its own production. If desired, any model can be modified to suit customer requirements.

Svarog

The company appeared in 2016, it was created by search engine enthusiasts with many years of experience. Their main goal was soon achieved, the result of which was the Rubezh deep metal detector. A whole line of these detectors is now being produced, allowing you to search for small coins in the most difficult conditions and survey vast areas in a minimum amount of time. The company's specialists are constantly improving their products, introducing the latest technological developments.

What to look for when choosing a metal detector

When choosing a metal detector, the main thing is to decide on the purpose of the search.Then evaluate the functionality of the device. The presence of discrimination will make it possible to cut off garbage during the search. The point-point mode allows you to determine the location of the search object down to almost a millimeter.

You should always pay attention to the weight and comfort of the armrest and the length of the bar. How quickly a person gets tired depends on these parameters.

Models with headphones make it possible to work in any conditions without missing the detector signal.

View

There are several types of metal detectors, depending on the purpose of the search:

Ground ones are suitable for searching for objects of various sizes, even coins, that is, they are universal. The main purpose is to detect a target by cutting off debris and rusty objects.

Deep ones are used to search for large objects.

Submersibles are designed for submersion under water, that is, the housing must be completely sealed. As a rule, they are produced without a display and with special headphones.

Special metal detectors are selected depending on the purpose of the search, for example, for coins and precious metals. Typically not intended to be submerged in water.

Industrial models are most often used on construction sites. The main purpose is to detect metal where it should not be.

The military is designed to search for explosive devices, ammunition and mines.

Another type is security. They can be portable or stationary, and are used to search for dangerous objects at strategic sites or in public places.

Detection depth

Depending on what you plan to find underground or water, you need to pay attention to the detection depth of the metal detector. Small items, such as badges or coins, can be found at a depth of up to 1 meter.Larger objects, from a machine gun to a helmet - up to 2 meters. And the largest things are located at a depth of up to 9 meters, for example, tanks.

Even if the manufacturer claims the best parameters, check them with the operating frequency. For surface search, a frequency of 14 kHz or higher is suitable. For detecting large objects 3-5 kHz. Universal models – 6-8 kHz. Ideally, a metal detector should have an adjustable operating frequency so that it can be used for different purposes.

Facial cleansing devices - rating of the best

Ground balance

To significantly increase the efficiency of a metal detector, it is necessary to correctly adjust the ground balance. This feature allows you to reduce the number of false alarms on overly mineralized soils. In professional models, manual adjustment is most often found. Semi-professional and “beginner” models always have an automatic mode, which does not allow fine tuning, but generally copes with its task.
