Best Gold detectors: Which One is for You?

Choosing the best metal detector for gold is not an easy task and for beginners it is almost impossible thing to do. On the market there are lots of offers and if you try to gain some insight on these devices, you will find yourself lost in the variety of models and prices. Besides, treasure hunting for gold can be very different. Someone is looking for it on the beach and someone is looking for nuggets. Both these targets require using different metal detectors.

In the current article we’ll discuss types of metal detectors, choose the best ones for gold prospecting, perform comparison study of the most popular models and help you to select the device with optimal combination of price and parameters. But, first of all….

Best metal detectors for gold

I have chosen the best gold detector on the market (from cheap to expensive), most time-proven and high efficient. If you think that there are more recommendable models, you are welcome to write me a message and I will include them into the list.

Fisher Gold Bug Pro

Fisher Gold Bug Pro review

Fisher Gold Bug Pro is a multi-purpose, high efficient metal detector for coin, relics and gold nuggets hunting on very mineralized soils. Despite the fact, that this model was designed specially for detecting small nuggets, unlike other metal detectors designed for gold digging, it can also be helpful when using small coins and jewelry.

Traditionally Fisher Lab designed Gold Bug control simple and easy-to-use even for beginners. Distinguishing characteristic of Fisher Gold Bug is that it uses sequential discrimination scheme, which is the most proper one when gold nugget hunting.

Sequential discrimination is a process when objects are excluded from the search one by one starting from metals with the lowest conductivity and further.

Also this metal detector has a ground balance function that can be adjusted both manually and automatically.

Operation frequency is 19 kHz. It weighs only 1,25 kg!

Garrett AT Gold

Garrett AT Gold review

Garrett (USA) has designed a new model of metal detector Garrett AT Gold specializing in non-ferrous metal and gold nuggets detecting. AT Gold has high sensitivity to small objects, like gold nuggets, rings, chains. For successful detection of nuggets, jewelry and small coins the device has high operation frequency (18 kHz) and minimized size of its search sensor.

Due to the fact, that AT Gold was designed basing on AT Pro, it can function under water, when it rains and in the places with heavy accumulation of dust and dirt.

The main difference between AT Gold and AT Pro, is that Garrett AT Gold metal detector has higher operation frequency 18 kHz (Garrett AT Pro has 15 kHz operation frequency); Garrett AT Pro is equipped with AT 8,5×11 DD coil in its set (it is a bit larger), while Garrett AT Gold has AT 5×8 DD coil (which is smaller).

Also Garrett AT Gold has wider possibilities when metal detecting on heavy-textured soils.

Minelab Gold Monster 1000 – best overall

Minelab Gold Monster 1000 review

Minelab Gold Monster 1000 – is a high frequency metal detector designed for treasure hunting on highly mineralized soil. Due to its high operation frequency 45 kHz it has very high sensitivity to small sized gold nuggets (0,2-0,3 gram). This metal detector was designed as the most adaptive system with several different configurations.

Minelab Gold Monster 1000 is completely automated device. That’s why you won’t have to adjust ground balance and threshold tone all the time. Therefore, while searching you will be able to devote more time to the process itself and not to the device settings. As for me, this is best gold detector on the market.

You have to make up your mind if you adjust the device sensitivity level yourself or use auto adjustment. At that you should keep in mind that automatic mode will decrease the device sensitivity for a sake of more stable productivity.

XP Deus II

XP Deus II review

Nowadays it is the best metal detector on the market. XP Deus 3 has accumulated all the best groundwork made by XP during all these years.

XP Deus II is a metal detector designed in 2022 that is one of the best multipurpose metal detectors nowadays. It is fast both for ground and underwater metal detecting, with FMF ® technology (fast multifrequency technology), extra lightweight (it weighs just 800 grams), the device is mobile and completely wireless: its control unit, search coil, headset, connection with a pinpointer are wireless. This is the best metal detector model designed by XP.

The most important about this novelty is its own technology, FMF – Fast Multi Frequency. This means the ability of the device operation simultaneously using a multifrequency from 4 to 45 kHz. At that, the frequencies in multi-frequency mode will be selected according to the device operation mode selected.

While XP Deus predecessor was good in many ways but not for beach hunting, XP Deus II can be used not only for beach hunting but the device also can be submerged up to 20 meters deep!

For underwater treasure hunting, there was designed a bone conduction headset that allows for hearing the weakest signals. Vibration mode was also added to the headset features.

Moreover, XP Deus II is a multifrequency device that efficiently searches both large-sized targets and small gold nuggets for which it has a special program, «Goldfield»

XP Deus II is as light weight as possible (it weighs 815 g max), which means that the device is very convenient in use. Since we all know how hard it is to sweep with any other device and then your hand starts aching. Now these issues are settled and you can enjoy using this metal detector.

Deus II is quickly assembled and dismantled and at that there is no chance of loosing or breakage of any device’s components. The metal detector has embedded batteries with at least 2 years term of service and then you should replace them with new ones. The batteries high capacity ensures very long service term without recharging.

XP Deus II can be considered the most light-weighted, ergonomic, and multipurpose metal detector with the highest efficiency when searching for any targets under any conditions. It is obvious that here we have a really new device, not just a veiled upgrade of the previous device model.

Minelab GPZ 7000

This is best metal detector for finding gold nuggets, heavyweight champion of gold metal detectors. But its price is very high.

This new metal detector by Minelab uses a breakthrough technology of gold detection – ZVT. This device stands head and shoulders above metal detectors of GPX series when detecting large and deep resting nuggets as well as detecting gold at any depth.

The device weights 3,32 kg, it has 14х13 waterproof coil. We can even call it a metal detector of tomorrow. All the results it demonstrates are significantly higher than that of previous Minelab models.

By means of this function (GPS-navigation) and application XChange 2 for PC you can put the marks you need on the map and also create a table of your own findings, record occurrence depth and weigh of nuggets and make any other notes in the field.

Now you won’t need a separate notebook or GPS, all information can be stored as a GeoHunt in your device and when you come back home you can copy all the data to your PC and show them on Google maps.

Supporters of serious, thorough approach to metal detecting by means of screen ‘Map’ can travel to the places they are interested in and look through GeoTrail, where they’ve been to, save their WayPoints (points that are of some interest to them) and FindPoints (their findings).

Another distinctive feature of Minelab GPZ 7000 metal detector is its high noise resistance and nowadays its is second to none in terms of this parameter. Due to its 256 channels of noise suppression you can use the device at maximum level of concentration, nothing strains your ears, there are no noises or sounds that distract you from the detection process, you won’t miss even the quietest and weakest signal from a target.

Can metal detectors detect gold?

Actually, on the market there are no metal detectors that can detect only gold. All these devices are capable of equally detect copper, aluminum, lead and other metals, not just gold.

However, there are metal detectors that are very good at detecting nuggets and jewelry or coins made from gold that rest quite deep under ground.

We can conventionally divide such models into two groups: devices for underwater and on the ground treasure hunting.

Quite often completely different demands are made for these devices because they function in various conditions.

In this article we’ll consider models that are used to find gold onshore, since we’ve already written about the best underwater metal detectors here.

In most cases people look for gold, silver or platinum jewelry in water. If you are going to look for jewelry on the beach or under water, you’d better read that review.

What are the features of these metal detectors?

So, let’s see, what metal detector is the best when searching for gold?

A metal detector for gold has some differences if compared with metal detectors of other types. These distinctions are due to features of the technology they use. Its main aim is to detect the smallest particles at final depth.

Though these devices can detect other metals, yet it isn’t proper to use them for ordinary metal detecting. The thing is, that the process will be complicated with constant signals received from metal rubbish which these devices are highly sensitive to.

Golden coins and other jewelry items are easily detected by devices that use high operation frequencies (i.e. higher than 14 kHz). The advantage of working at such frequency is the ability to detect small objects such as earrings, rings, coins.

Metal detecting of golden items has some peculiarities. Gold has conductivity and discrimination scale parameters similar to those of oxidized iron. Due to this a metal detector for gold should have an expanded range of ferrous metals.

Coins, nuggets and jewelry made of precious metals is most cases are small, that’s why the device should also be highly sensitive to small objects.

It has to be able to function on highly mineralized soils, since usually these are the areas where golden items and nuggets are detected.

Metal detectors for gold, nuggets and coins hunting mainly use VLF (Very Low Frequency / Low Frequency) and PI (Pulse Induction) technologies. Some of them are designed to work either on the ground or underwater, the others can function both underwater and on ground.

Nowadays VLF technology is a more widespread one, since it is more multi-purpose approach. Metal detectors that are using this technology have operation frequencies up to 100 kHz. The devices utilizing VLF- technology have efficient discrimination and support multi-frequency functioning.

However, one of the most expensive devices for gold hunting use PI technologies. These metal detectors have high sensitivity to the smallest objects and demonstrate stable productivity on mineralized soils where ordinary metal detectors just fail.

The key feature of such metal detectors is minimal set of functions and high energy consumption.

VLF and Pulse Induction – what’s the difference?

VLF-metal detectors have operation frequencies from 3 to 30 kHz; from 30 to 300 kHz (deep search) and from 20 to 100 kHz (in the upper soil layer), but there are also multi-frequency devices. They allow detecting large targets at low frequencies as well as coins, earrings, rings – at high ones.

PI technology means that the device emits a bunch of alternating short or long electric pulses (MPS, Multi Period Sensing) or alternating voltage is applied to its head (DVT, Dual Voltage Technology).

PI-detectors «see» gold deep under ground, they are very sensitive to small objects, ignore noise generated by soil rich in magnetic inclusions (sodium and potassium salts, ferriferous oxides) and «rubbish» (nails, pieces of various metal containing objects).

Often these devices function using some special programs.

For example:

  • «leveled sensitivity» (improves response from small fragments in mineralized soil, excludes signals from magnetic rocks)
  • «small gold» (improves the device sensitivity to coins and jewelry in mineralized soils)
  • «Salt / gold» (helps to perform treasure hunting in alkali soil, beaches, deposits with mineralized soils)
  • «Improved sensitivity» and or «fast response» (for deep metal detecting in neutral soils)

Example with a gold chain

One of the most popular things found by means of metal detecting is a chain or some parts of it. However, this is one of the most hard to find targets for a metal detector (it can be made from any metal, not necessary from gold).

The metal detector sees the chain not as a single object, it detects its chain links. The coil of the device doesn’t identify mass of the whole chain and it seems that it tries to ‘divide’ it into separate chain links and detect them as different targets located close to each other.

That’s why if the chain lies lengthwise, you won’t get sufficient detection depth. If its rests as a ‘pile’, there is a chance to detect it even at a large depth.

Another key factor is the chain link size – the larger (the heavier it is) the deeper the device can see such a target.

As a rule, only expensive VLF – detectors can see a chain even not very deep, if it lies lengthwise and yet not all of them can pass this test. PI detectors deal with this task more successfully.
