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, perform comparison study of the most popular models and help you to select the device with optimal combination of price and parameters.
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.
- «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.
Best metal detectors that detect gold
I have chosen the most time-proven and high efficient ground metal detectors for gold, though yet there can be another opinions. 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 – best entry level metal detector for gold
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!

White’s Goldmaster GMT
Whites GMT GoldMaster Series is aimed at gold nuggets hunting and this is a further developed model of Goldmaster family. This device has a perfect ground balance function and it is convenient to use it even in very tough conditions.
In comparison with the previous models of metal detectors made by this company, its sensitivity to small sized objects has increased due to using high-speed threshold adjustment control.
Ground balance function was simplified and improved, it became more precise and it’s performed in increments of 1/1000 by means of two buttons (“+” and “-”) on the front panel. Whites GMT metal detector has an adjustable speed of the threshold automatic tuning and response range switch.
Since gold nuggets hunting is rather specific process, to perform it discrimination was minimized. In Whites GMT discrimination functions only in ‘Iron/non-ferrous metal’ range. A special analyzer helps to define presence of iron in the soil and increases this probability.
Fast change of soil mineralization is offset by speed adjustment of threshold automatic tuning SAT. The device ground balance function has become easier to use and more functional. It is performed by means of two buttons on the device control panel. Whites GMT is also equipped with a mode of precise target detection (pinpoint).
