Deteknix Quest Q20 & Q40 Metal Detector Reviews

 

Deteknix, a relatively new competitor in the detecting world have released a line of metal detectors called the Quests.

UPDATE: Deteknix no longer trades under the brand name Deteknix. They have rebranded now to Quest. After much controversy about the first models of the Deteknix Quest metal detectors.

The metal detectors I am reviewing and talking about below are the latest models and not the controversial first models that were sued for copyright by First Texas Products.

There are 3 detectors available the Quest Q20, the Quest Q40 and the QuestPro.

Quite frankly I’m absolutely shocked at how little recognition these machines have had so far and why they aren’t making much more of a noise with detectorists.

Let me explain in depth what I have found about the Q20 & the Q40 metal detectors (quest pro review coming soon), their features, their pro’s and cons and their excellent value for money!

I’ve compiled all three detector reviews and assessments into one article page. You can jump to any part by using the table of contents.

Quest Q20 Metal Detector Review

Deteknix Quest Q20 Review

Let’s start with the Quest Q20 the baby of the Quest metal detector range and subsequently the lowest priced.

Quest Q20 Appearance

The first thing you are going to notice is the appearance. It’s innovative and sleek and has a slightly futuristic design and look to it.

When I first saw these detectors I thought that they were going to be very expensive.

The shaft is made up of 3 pieces which are demountable and adjustable.

Length can be adjusted from 80cm to 130cm.

It’s ultralightweight, weighing in at just over 1.1kg. 1050 grams to be precise. This is including the weight of the stock coil if you are to upgrade this would, of course, add to the weight.

When they first released the range there were apparently a few design flaws however these have all been ironed out now.

In general, the machine is very sturdy and comes with a 5-year warranty.

Q20 Control Panel & Buttons

On the control panel of the Q20, There’s a very large LCD screen complete with backlight. The Headphone Socket is located at the back.

There are 5 buttons in total: up and down arrows, an M for the menu, a pinpoint button, and a “level up” button.

The simplicity of a minimal amount of menu options and buttons is going to make this absolutely perfect for the beginner detectorist.

On the Screen, you receive a wealth of information on a large clear and easy to read screen. Firstly you have the target ID number, An Icon to represent the mode you are currently in, volume level, depth indicator, the target segments, battery level and when in the mode a pinpoint crosshair display.

Detecknix Q20 Modes & Features

There are 3 modes for the Quest Q20 these are coin mode, jewelry mode, and All-Metal.

All of the modes have the option to set ID discrimination so you can notch out target I.Ds numerically. There are 10 segments you can choose from.

For a machine that is so low in price ground balance is a rare feature, the Q20 includes a manual & auto ground balance feature this is achieved by selecting the menu option and pumping the coil up and down just above the ground or simply set it to Auto.

The inclusion of the USB chargeable lithium battery is another noteworthy feature of this metal detector potentially saving you hundreds over the year. The battery life is very good you should get roughly 20 hours worth of detecting out of a full charge.

Quest Q20 Buyers Guide

You can currently buy the Quest Q20 from a few places online. If you wanted to buy from a metal detector retailer then we have found them in stock on detectorbits.co.uk for around £230 with free delivery.

You can also purchase your Q20 from eBay and Amazon below for the following prices.

Buy a New Quest Q20 Metal Detector  for between £210 – £225

Buy a Used Secondhand Quest Q20 Metal Detector for between £120 – £170

There are not many used units showing up anywhere which is a very good sign. This is a solid indicator that people are not parting with the machine.

Quest Q20 Review Summary

It’s got to be said these Quest machines are a hidden gem in the detecting world, especially for the budget price.

The recovery speed of the detector is very fast. Faster than one would expect.

The depth capability of the Quest 20 is highly dependent on the mineralization of the ground but reports show that it’s hitting 8 – 10″

You’re getting a very attractive metal detector that is aimed at the beginner that includes the power of a mid-range machine all for a budget price. Basically, the machine’s performance is worth twice its price.

Quest Q40 Metal Detector Review

Deteknix Quest q40 ReviewThe next model in the line of Quest metal detectors is the Q40. The “middle” machine.

Most metal detecting companies seem to release in 3 models, for example, Garrett with the Ace – 150, 250, 350. Then Minelab with the X-terra 305, 505, 705.

So how does the Quest Quest Q40 fair as the middle machine?

Quest Q40 Appearance

Appearance wise nothing has changed from the Q20 so I won’t go into great lengths talking about it.

You can view appearance information for the Q20 above. Same colour, same innovative sleek design.

Quest Q40 Control Panel & Buttons

The control panel and buttons on the Q40 are exactly the same as the Q20.

The only difference between the two is the information you receive on the LCD screen.

You can see the information you will receive to the LCD screen on the image below.

Quest Q40 Modes & Features

So what added features and modes does the Q40 bring in comparison to its junior model the Q20.

As per the Q20, we have the preset modes, coins, jewelry, and all-metal, an added beach mode, and the addition of a much-welcomed custom mode so the user can preset their own preferences and fine-tune the program.

The Quest Q40 has all of the same features as the Quest Q20. (You can see these above in the Q20 specs) That being said it throws in a couple of major differences.

The machine runs at 13khz as opposed to the junior model which runs at 9khz. The frequency of this model can also be shifted when near other detectorists or in a location with high interference.

Wireless headphone technology is also a major upgrade from the Q20. You still, however, have the option of plugging in the usual headphones.

6 Tone response as opposed to the dual response in the lower model. Allowing you to receive a much more detailed audio response.

FESEN, this allows you to hear good targets that could be masked by iron or bad targets. Using this feature will increase the audio capability and allow you more of a chance of hearing the good signals.

So what’s the difference in price between the Q20 and the Q40?

You can currently buy the Deteknix Quest Q40 from a few places online. If you wanted to buy from a metal detector retailer then we have found them in stock on detectorbits.co.uk for around £370 with free delivery.

You can also purchase your Quest Q40 from eBay and Amazon below for the following prices.

Buy a New Deteknix Quest Q40 Metal Detector  for between £369.95 – £399.95

Not a huge difference in price between the Q20 and the Q40. For me, the wireless headphone technology is worth the price difference alone.

Quest Q40 Review Summary

After extensive research and speaking to a few detectorist who have used the Q40 it has to be said that I’m still shocked that more people don’t own one.

The Quest Q40 is an absolute steal for the price.

The wireless headphone technology is probably my favourite feature, no more tripping over your headphones or taking them on and off constantly all day.

Again you are getting far more power and performance than you should for what you are paying.

I’d highly recommend this to beginners and even to more advanced detectorists wanted to upgrade from their first metal detector. For the beginner with a slightly larger budget this is going to last you a long time and as far as I can see the detector is future ready with a Sync menu option which is not used at the moment.

I investigated the “sync” menu option further and it seems that you will be able to update the firmware in the future activating more features.

It has everything you need and it’s lightweight. It looks nice and there are so many reports saying the recovery speed is fantastic.

As I am writing about these Quest metal detectors I’m convincing myself to buy one as a spare 🙂

Please keep an eye out for my next update on this page where we will review the Quest Pro.

I am currently trying to get my hands on one to borrow so I can give you an in-depth review.  I’m thinking the worst thing about the Quest-Pro so far is the difficulty to purchase one in the UK.
