You might wonder, can metal detectors detect gold? The answer is, it depends. Fortunately, the market today offers lots of products to aid in any of your adventures. You can quickly get metal detectors for gold, which effectively strikes rich, or even getting trash. But not all metal detectors can help in locating gold.
Gold Hunting with a Metal Detector
Metal detectors are products that aid in gold nuggets hunting. However, the metal detectors come in a variety. Some include hand held metal detectors used in finding shallow hidden treasures. They are cheaper but do not have a ground balance ability or block electrical interface of highly mineralised soil.
Meanwhile, you can go for giant coil metal detectors. They are perfect tools for highly mineralised soil, large, and deep hidden gold detection. It is a thrilling experience to find a big gold rush that can be highly profitable. However, the main task is always to locate the gold nuggets, which does not come easy.
Therefore, you need to have adequate knowledge of metal detectors. This article discusses the topics on metal detectors for gold and what to expect in the market.
When purchasing metal detectors, you are likely to choose either the VLF technology or Pulse Induction technology. The technologies are standard in the market and have a role in detecting gold. Therefore, all you need is to understand your area of hunting gold. It would be best if you also understood the various types of gold nuggets you are hunting.
So let’s begin by having a look at the concept behind metal detectors for gold.
How do Metal Detectors Work?
You have seen or used metal detectors at the security checkpoints innumerable times at the airport. But how do the sensors work when you walk through them? Most airport metal detectors use pulse induction technology to detect metals.
Inside the booth-like structure, a coil of wire on both sides works as a transmitter and a receiver. They send pulse currents through a loop which then creates a transient magnetic field. Depending on the metal detector manufacturers, the pulse sent can range between 25-1000 pulses per second.
So, any metal that passes through the detector disrupts the magnetic field created by the metal detector by creating a magnetic field of its own. That disruption makes the reflected pulse take longer, causing the sampling circuit monitor to sound an alarm for something unusual.
How do Metal Detectors Detect Gold?
Metal detectors can quickly locate gold through the use of electromagnetism (production of the magnetic field by current flowing through a conductor) force. However, metal detectors come in a variety and for different purposes. For instance, there is the walk-through metal detector that you will always come across in banks, airports, or other guarded spaces.
A standard metal detector will comprise a shaft, search oil, and control box. Such metal detectors will always use the VLF (Very Low Frequency) technology, the optional Beat Frequency Oscillation, or Plus Induction technology.
However, the VLF is considerably affordable and ideal for beginners with a low budget for a metal detector. The VLF is also most preferred for its moderate frequency of 3-70kHz, making it quick in detecting metal and jewelry.
Experts will commonly use pulse induction metal detectors which are mainly used in detecting gold nuggets. Its advantage comes with the ability to find and sense through maximum underground depths.
I will explain the concept behind the VLF model in sensing gold and metals for beginners’ better understanding. A VLF model handle comes with a head wire wrapped by a transmitter coil at the end.
A battery in the metal detector will provide the loop with an electric charge to generate a magnetic field around the coil. On the head of the metal detector, you will find another coil that connects to a circuit that ultimately connects to a loudspeaker.
Therefore, moving the detector close to a metallic object like gold creates an electric field, which initiates another magnetic field inside the gold. The new magnetic field created on gold will then overlap the magnetic field produced by the detector, which adds a surge of electricity through a receiver coil directing it to the receiver circuit, then to the loudspeaker, and then sets a beeping sound alarm.
The closer you approach the gold or metal, the more the beeping sound gets vigorous. That is due to more electricity flowing to the loudspeaker and a strong magnetic field created to the receiver coil.
Where Can You Gold Hunt With a Metal detector?
Before going for a gold hunt, it is best first to perform adequate research. Some of it will involve searching geographical survey websites, going into national or provincial offices for information and maps, or looking at the previous places you were successful in the gold hunt.
When done with the research, choose the exact geographical area and get permission from the respective authority before beginning the search.
What is the Necessary Equipment in Gold Hunt?
Before selecting a gold hunting day, consider gathering the necessary equipment for the task. First, you need to choose an effective metal detector for gold. Here you can do that by visiting metal detectors for gold reviews to help you get the best. You will find the VLF detectors in plenty of options, and to make your work more manageable in the search, go for automatic ground balance control.
It would be best to consider going for equipment with a depth display to determine the depth of your desired object. The giant coil detectors are best for greater depth, while the smaller ones are good enough for shallow depth.
It is advisable to have headphones that will help get to hear even the slightest alarm noise. Having all equipment ready, pick a day that you can go gold hunting.
What Factors Should you Consider When Selecting a Metal Detector?
As I have explained earlier, metal detectors create a small magnetic field that responds to objects hidden in the ground. But there are some factors to consider when selecting a metal detector.
- Aperture & Product Size
- Sourced Materials
- Types of rocks or soil underneath
- The depth of the object
- Metal Types
Therefore, the listed factors make the difference in metal detectors’ consistency and accuracy to uncover underground gold nuggets. A sensor with lower frequencies is not viable for gold locating because of gold’s low conductivity and size. It would help if you had high-frequency metal detectors in identifying such small objects as they are very accurate.
So, it would be best if you went for detectors that are PI-type or multi-frequency. The two types are the most expensive kind of metal detectors. However, they are the best with features that help in locating gold grains.
Do Metal Detectors Detect Gold Rings?
In the recent innovations by hobbyists, there is a lot to appreciate. Among them is the making of metal detectors designed for finding rings made of valuable metals like platinum, diamond, and gold.
However, the question is, “do metal detectors detect gold rings?” Yes! The majority of metal detectors can easily detect any ring regardless of its metal content. However, it is difficult for low-frequency detectors to identify gold hidden or buried deep underneath the ground.
If you lost a gold ring today, you are confident that you have a high chance of finding it. Therefore, getting into such a circumstance should not bother you.
Can Hand Held Detectors Detect Gold?
Yes, it is common for handheld metal detectors to detect ferrous metals which contain iron. The metals are highly magnetic for the detector to induce an electromagnetic field, causing detection. Meanwhile, it would help with particular handheld detectors to detect precious metals like gold, silver, or copper on the ground surface. They are commonly known as treasure hunting metal detectors.
However, they are not powerful enough to discover deep hidden precious metals.
Can the Garrett Ace 400 Find Gold?
Yes! It is a highly recommended product in hunting jewelry like copper, gold, or silver. The Garrett Ace 400 comes as a premium option that offers you a lot of working features.
Some of them include:

Will Garrett Ace 300 Detect Gold?
Garrett Ace 300 will only find gold jewelry but not gold nuggets. Nuggets are located in highly mineralized soils, which require a pulse induction machine to discriminate against other minerals like iron.
Fortunately, its multiple features make it at the top in a grade of entry-level devices. It yet remains the best option for beginners for having a simple interface. The price is low and affordable for the hobbyist looking for quality devices at the lowest price.
Can Gold be Found in Any River?
No! The ideal river to find gold is lode deposits, alluvial deposits, bench deposits, residual deposits, streambed deposits, flood layers of ancient rivers. A lode deposit is a fissure or cracks in hard rock full of gold. It is commonly the source of placer deposits.
It is essential to go for crevices or cracks in the rocks at the bottom of a stream. There is a high possibility of gold settling into them. Additionally, rough or irregular bedrock surfaces are good traps for gold.
Can Cheap Metals Detectors Find Gold?
Yes! The cheap metal detectors have the capability of detecting gold. Most of them use VLF technology which works efficiently for its moderate frequency of 3-70kHz. That makes it quick to detect metals and jewelry objects like gold.
Which Metal Detector is Best for Gold?
When choosing the best gold detector, you must consider your budget or target in the gold hunt. However, there are three categories of best metal detectors to select your desired product in my list. The products I selected have excellent and practical functions in detecting gold.
- Low Budget Product- Nalanda MD056
- Moderate product- Fisher Gold Bug Pro Metal Detector
- High End – Minelab GOLD MONSTER 1000
Do All Metal Detectors Detect Gold?
Any metal detector will locate gold, but the big difference between a cheap and expensive detector is the system in use. Some detectors lack ground balance ability, or block the interference of extreme mineralization in soil or rocks or even the depth.
Therefore, any detector can find gold but not the tiny flakes deposit you find in streams. The more sensitive a product is, the more you need to spend money on buying. A good experience in handling the product is essential in finding gold grains.
Which Detector is Best for Finding Large Deep Targets?
Two box detectors like Fisher Gemini-3 are good examples of metal detectors for finding large or deep targets. However, a two-box detector with a connecting handle works as a standard detector for it goes deep but can only help you find gold grains the size of a cantaloupe melon.
