Metal detectors: Quest X5, X10, Q20, Q30, Q40, Review

Here you will find Quest metal detectors review. The article has information about their origin, the manufacturer, which device models are currently on sale, whether they are worth the money spent, etc.

History of the company

Deteknix Inc brand has existed in the USA since 2007, however, metal detectors produced by this trademark were manufactured in China.

Everything started from detectors used for inspection by security services, then since 2009 Deteknix started manufacturing and selling metal detectors.

In 2018 First Texas Company bring legal action Deteknix and won the case. The court held that Deteknix metal detector model used hacked software of Teknetics T2 metal detector.

However, they succeed to make a deal and two companies settled out of court confidentially. After this Deteknix had rebranding and started using its new name Quest Metal Detectors.

At that, the company moved further, and they worked hard to create their own software and technologies. Thus, nowadays nobody can accuse them of using somebody else’s stuff.

In defense of the company we must say that they do try to design quality metal detectors. They are not cheap Chinese fakes that have flooded the market. The devices are fully-featured metal detectors, each of which differs from the other devices in the product line.

Besides, the company is growing and tries to produce new metal detector models. Certainly, when it comes to your own best practices and technologies, they don’t come all at once, but the company keeps developing.

The main advantage of QUEST metal detectors over metal detectors made by famous companies such as Minelab, XP, Garrett is the price of its products. QUEST devices offer a quite good functionality, which can be compared to the one of the beginner level metal detectors made by the above-mentioned manufacturers, while the price is sufficiently lower, and the price difference is sometimes up to 50 %.

The list of basic models with a brief description

The metal detectors are designed using a single scheme – straight three-segment shaft, a handle (looks like upside-down ‘T’) with a control unit on it, it resembles a handle of police baton.

This handle can be shifted along the shaft to enable balancing and adjusting the metal detector to the individual user parameters.

Displays of all Quest metal detectors, including Q20 are 60×70 mm large. The main feature of all Quest metal detectors is an embedded lithium battery accumulator, thus there is no battery holder on the device shaft.

Quest X5

Quest x5 is a new device produced in 2019. This is a multi-purpose metal detector to search for a wide range of targets, which is not very expensive.

Quest X5 uses classical VLF technology, its operating frequency equals to 8 kHz. The standard search coil the device uses is elliptic 9,5 DD (Double-D) coil.

Discrimination function of Quest X5 allows ignoring unwanted ferrous targets. The metal detector has 3 pre-set search programs – All metal, Coin and Jewelry.

Quest X5 has a simple and user-friendly interface, so it will take you several minutes to master the device.

You’ll be able to know what kind of target is under the search coil, before you dig it. Multi-tone sound target response provides low tone for ferrous targets, medium and high for non-ferrous ones.

Graphic scale has segments for all kinds of metals. However, VDI number is what helps the most when defining the target (large digits in the center of the display) – this is a numerical designation of the target metal type.

For precise identification of target center, the metal detector has a pinpointer mode.

The device uses an embedded battery accumulator as a power supply. Therefore, it can be charged using any USB jack or powerbank. The battery provides continuous operation time about 19-20 hours.

So, what makes X5 different from other low-end metal detectors produce by other companies?

The metal detector offers ground balance function, VDI, high signal processing rate, large contrast display with a backlit, an embedded flashlight, battery accumulator that can be charged using any USB jack, DD coil is included into the device package set, the device is protected from rain and at that the metal detector is rather light-weighted.

You will not find such a combination of functions in other metal detectors, only Quest X5 has it and….. Quest X10.

Quest X10

It is easy to guess that this metal detector is similar to the previous one, but it differs a bit. So, what is different between Quest X10 and Quest X5?

The device has an adjustable threshold tone, which is a professional function used to increase the discrimination function precision. Also, tones of target sound response can be adjusted in this device model.

Another feature is Pitch mode, when the sound response becomes dynamic depending on the signal – if the target is on the surface, the signal is loud, if the target is deep, the signal is quieter.

Quest Q20

Quest Q20 is a good metal detector for beginners. It has three search modes, adjustable ground balance, large display and long life of the battery accumulator. Also, the device is quite light weighted.

The metal detector uses VLF technology and has an operating frequency equal to 13kHz, which enables multi-purpose treasure hunting for targets of different size – from small coins to large stashes and relics.

Discrimination data can be seen on the graphical scale that has 10 segments, which allows quite precise identification of the target composition. Besides, for even more precise there is a VDI number on the display (it varies from 0 to 99).

Quest Q20 has three pre-set modes that allow automatically adjust the device for some specific search conditions.

The metal detector has automatic and manual ground balance function, which enables precise definition of the soil type and decreasing its influence on the signal quality. To provide convenient usage of the device, it is equipped with a flashlight, rubberized handler, that can be adjusted as well as there is a possibility to charge the device using USB jack.
