Best Metal Detector for Gold Nuggets

Marc McDermott

Are you looking for the best metal detector for gold and are flabbergasted by all the choices – and the crazy price tags? This article will help make your decision a no-brainer.

Our top pick for best value for all-around prospecting is the Fisher Gold Bug Pro; a powerful gold detector that’s perfect for beginners and those on a budget. 

We recognize that not everyone has the same intended use, skill level, or budget. That’s why we give you several recommendations in this guide. So, what are the best metal detectors for gold?

Best Entry-Level Gold Detectors

Best Intermediate Gold Detectors

  • Fisher Gold Bug 2: Most sensitive to small nuggets in neutral ground
  • Garrett ATX: Submersible to 10′, a PI gold detector also great for saltwater and relic hunting
  • Minelab Gold Monster: Best option in it’s class for automatic sensitivity and ground tracking

Best Expert-Level Gold Detectors

* The GPZ 7000 uses Zero Voltage Transmission (ZVT) which effectively gives you two machines in one – a deep PI machine, and a high frequency VLF machine.

Our Buying Guide

E​ver since James Marshall’s 1848 discovery of gold at Sutter’s Mill, gold prospecting in the United States has been the ultimate treasure hunt.

Prospecting gold nuggets with a metal detector is a thrilling hobby that’s both fun and (financially) rewarding.

But with so many machines on the market, how do you know which is the best metal detector for gold?

This go-to guide is packed with useful information that will help you make the right choice so you can start digging your very own gold.

How to Choose​

Before we get started, I want to make a public service announcement if I may.

All metal detectors will find gold nuggets if they’re in the ground (and big enough) – not just gold detectors.

A gold metal detector is simply a detector designed specifically to detect tiny targets in mineralized ground. That’s pretty much it.

So what makes a good gold detector?

It may surprise you that it’s much easier than you think to choose the right detector.

Some of the biggest factors include:

  • Where (geographically) you’ll be doing most of your gold prospecting.
  • The size of gold nuggets that have been found there in the past. If you don’t already know, I recommend joining a local prospecting club or talking to local claim owners.
  • Ground conditions. Is it highly mineralized? Is there a lot of trash?
  • Other uses. Do you want to use the same detector for coin, jewelry or relic hunting?
  • Budget.

You’ll need to ask yourself these questions before you even consider which detector you’ll buy.

Spoiler alert: there is no universal ‘best metal detector for gold’.

Although the GPZ 7000 is close for those of you who can afford a detector that’s the same price as a car.

The question should be, what is the best gold detector for your answers to the above questions?

Just because the Minelab GPX 5000 costs more than 6x the amount of the Fisher Gold Bug 2, doesn’t mean it’s better.

If I were hunting in low/moderate ground on top of bedrock in an area where the nuggets tend to be small, I would actually opt for the Gold Bug 2 over the GPX 5000.

Am I crazy? No….not the last time I checked anyway…

Now let’s dive into the reasons why this is the case by deciphering the most important elements of any gold machine.

Detector Technology

The first thing you have to decide is which technology to use – VLF or PI.

VLF stands for Very Low Frequency and is the same technology used in detectors built for coins, jewelry, and relics.

VLF detectors broadcast at frequencies measured in kilohertz ranging from 3 kHz to 70 kHz.

Here are five reasons why you might choose a VLF over a PI

  • You’re a beginner.
  • You want to use the same detector for other detecting like coins, jewelry, relics. (Read more on the best metal detector for coins).
  • You’re hunting for small to medium-sized nuggets at depths under 8” (most common).
  • You’re hunting in areas with lots of trash and need to discriminate.
  • You want to spend less than $2,000

PI stands for Pulse Induction and is used in specialty detectors designed for maximum depth in highly mineralized ground.

PI detectors broadcast pulses and are measured by pulses per second.

Here are five reasons to opt for a PI machine over a VLF:

  • You’re an experienced gold hunter.
  • You want a specialty machine built just for gold nugget hunting.
  • You’re hunting for larger gold nuggets at greater depths AND aren’t so much interested in the smaller, shallower nuggets.
  • You’re hunting in highly mineralized ground with low levels of trash.
  • You have over $2,000 to spend.

Now that we’ve identified the two camps let’s talk about some technical differences.

Operating Frequency

We already discussed that VLF detectors are best when searching for nuggets that are small to average in size.

The next thing to decide is the operating frequency of the VLF.

As mentioned above, VLF machines typically range from 3 kHz to 70 kHz with the most popular gold VLF machines in the 13-50 kHz range.

That is a huge range. So which is better?

Again we go back to nugget size.

Side note: This guide is not about where to find different sized nuggets, but larger nuggets will most often be at the highest elevations of your site, while the smallest will be at the lowest elevation – usually in a stream bed.​

In the United States, larger nuggets are most often found in Alaska, medium in Western States, and small in Eastern States.

The biggest and best nuggets in the world are typically found in Australia.

Now back to the techy stuff…​

There is an inverse relationship between frequency and nugget size (as well as maximum detection depth).

Both lower frequency VLF and PI detectors will find larger nuggets at greater depths – but will struggle to find smaller nuggets at shallow depths.

Alternatively, higher frequency VLF machines are better at finding smaller nuggets at shallow depths – and struggle to get greater depths.

So which is better? Well, neither…

It all depends on your particular area and the what’s been found there before (and at what depths).

The same concept holds true for search coil size. Again there is an inverse relationship where larger coils get bigger targets at greater depths, and smaller coils get smaller targets at shallow depths.

Smaller ​coils are also better for rocky areas where you need to maneuver around large rocks and get into tight spaces. 

They’re also preferred over large search coils in highly mineralized ground​ since they will ‘see’ less of the ground at any given time.

Let’s revisit my comparison at the beginning of this article between the GPX 5000 and Gold Bug 2 to help understand my reasoning.

The Gold Bug 2 is a 71 kHz VLF machine with a small, 6.5” coil.

The GPX 5000 is a PI machine with a large 11” coil.

So if you’re hunting on bedrock in an area with small nuggets and ground that is not highly mineralized, the Gold Bug 2 is the clear choice.

Using the GPX 5000 in this scenario might actually cause you to miss nuggets altogether!

I don’t know about you, but I’d rather dig several small nuggets than no nuggets at all because my machine is only looking for large ones.


Another factor in determining what range of frequencies to look for when choosing a gold detector is the ground mineralization for where you’ll be hunting.

After all, gold is most commonly found in areas of mineralization – at least to some degree.

Lower frequency VLF and PI machines will handle high mineralization much better than high-frequency VLF.

If you’re in areas of extreme mineralization such as black sand in a stream bed, then a PI will likely be your only option as it will see through the ground and not false.

So you probably don’t want to hunt with the Gold Bug 2 for example if you’re in areas of high mineralization if you want to avoid constant falsing.

Another feature to consider when dealing with mineralization is the ground balance.

Almost every gold detector comes with automatic ground balance (or ground tracking) – but not all ALSO have manual ground balance.

So I recommend you invest in a machine that has both forms of ground balancing.

Is your head spinning yet?

It’s really not as complicated as I’m making it sound.

In fact, it’s probably more complicated for me to explain all this in writing than it is to decide on a detector.


In addition to the varying degrees of ground mineralization, you also need to consider how much trash is in the ground.

Now I use the term trash loosely here. When I say trash, I’m referring to anything that’s not gold.

VLF detectors have the advantage of electronic metal discrimination – meaning you can choose to ignore trash signals and only focus on good, gold signals.

Alternatively, PI detectors either struggle with discrimination or have none at all.

So if you know you’ll be in areas with a high trash density, you might do well to opt for a VLF detector. Otherwise, you’ll spend your entire day digging trash.

Parting Words​

That wasn’t so bad, was it?

If you’re new to metal detecting and these concepts are not already familiar to you, I recommend reading this article a few times.

Once you understand everything we’ve talked about in this article, your biggest question should be: “What if I want to find both small shallow, small nuggets, AND large, deep nuggets?”

Excellent question!

The reality is that unless you can anti-up for a Minelab GPZ 7000 (currently $12,499 MSRP), you’re going to want two machines.

My best advice is to get the Fisher Gold Bug 2 for your small, shallow gold, and whichever of the Minelab PI machines your budget allows for the deep, larger nuggets.


Now that you have a better idea of which gold detector is best for you, here are a few accessories I highly recommend for all prospectors:

  • Plastic scoop to wave dirt/rocks over coil during recovery.
  • Pick to hammer through rocky ground
  • Pinpointer or coil probe to quickly pinpoint those small nuggets
  • Coil Cover to protect your coil from damage
  • Vials to store your fine gold
  • Shoulder or chest harness to take the weight of the detector off your arm
  • Different coils to adapt to the location your hunting
  • Headphones to hear those faint gold signals
  • Strong Magnet to quickly pickup iron trash and ‘hot rocks’ before digging


I hope this article was helpful and puts you on the right path for choosing the best gold metal detector for your needs.

    Thanks Mark that was really helpful!

  5. Mr nas

    I regret not reading this article before I bought mine. Recently i bought MD 508 metal detector. It’s purpose was to prospect gold but today seems to be a waste because it never worked for me, it would make noise through out. At least now i know that i have to consider a lot before i buy 1

  6. Derek Stallings

    Excellent information for a newbie like myself! Thank you…Derek from Southern Oregon

  7. dave

    thanks for great review

  8. shaw

    hi Mark.
    can u tell which one is better, Gemini 3 or Garrett GTI 2500.. i want is for deep seeking. i will be going middle east for some treasure hunt. thankx

    • Marc McDermott

      Those are 2 totally different machines and can’t be compared. Gemini is used to find very large deep objects like oil tanks.

  9. Karl

    Hi Mark, I hava lead for gold coins buried in Mexico. I dont know how deep they would be but some treasures have been found in the area. What would be the best for less than $2k?
    Thank you

    • Marc McDermott

      Hard to say. I’m guessing it would a cache that’s buried quite deep? If that’s the case then you should think about a 2-box style detector like the Fisher Gemini III.

  10. Alex

    Hey Mark,

    Is there a gold detector that works well in shallow water? I was planning on getting the GB2 and buying both coils. I’m close to the Feather River, Oroville area. they find lots of gold in the Rivers up there. I’m brand new at this. I appreciate your time and advice.

    • Marc McDermott

      Hi Alex. How shallow are you talking? If you want a completely waterproof gold detector, then take a look at the Garrett AT Gold

  11. Rob

    I live in Northern British Columbia, Canada and I was wondering which unit would be best for black sand, hot rocks and mineralized ground… The Equinox 800 or the Garrett Infinium LS.
    Thank you for your reply. I appreciate your article.

    • Marc McDermott

      I’d probably go with the Equinox.

  12. Bogdan

    What is the approximate price of FISHER GOLD BUG 2? Has an LCD screen? Can you link me?

  13. Geoffrey Nelson

    Howdy Mark,
    I am a gold miner in Alaska and have been wanting to add a detector to my arsenal for years. Lots of cleared bedrock after washing placer gravels and of course I can’t help but wonder about anything great I might have missed. We get nuggets up to 2 ounces and in the glory days of the Porcupine gold rush there were pieces much larger than that found regularly. The ground here is very hot in places and HIGHLY mineralized in places. I was wondering if you think the Garret ATX would be better than the Gold Bug 2.
    Thanks for your time.
    Kind regards from Alaska

    • Marc McDermott

      Yes I’d go with the ATX over the GB2 in that case. If budget is no issue, look at the Minelab gold machines.

  14. Roland Kuss

    I live in calgary alberta do i need a garret 400 i 0r is 400 good so confused thank you

    • Marc McDermott

      I believe the 400i is more for European markets.

  15. William Coates

    Thanks Mark, I’m a beginner and this information has really helped me. I’m looking to venture into the prospecting process and want to incorporate a metal detector in my hunting.


  16. Dave Graham

    I read your article and found it very informative,I appreciate having good information. I have been hobby metal detecting for about 12 years, as I get closer to retirement I am hoping to do a lot more detecting. I currently own a Whites MXT, which I have two coils for, the standard search coil and a double D it is the only detector I have ever owned. I like to hunt coins and relics but I would like to be able to do a better job hunting for gold. I live in an area with a lot of mining history in North Central Idaho. The MXT has a prospecting setting on it which I use when I use the double D but I have never been successful finding any gold. Would the Gold Bug 2 be a lot better for finding gold? Please let me know your thoughts.
    Dave Graham

    • Marc McDermott

      It really depends. Do you know other prospectors in the area? Ask them the size of nuggets they’re finding and what detectors they use. The Gold Bug 2 is a gold-only detector. I would not use it for anything else.

  17. Richman

    i want to hunt for big nuggets but i am on a tight budget, is it feasible to use the GPX 4500 and what are the pros and cons of using it.

    • Marc McDermott

      What is your budget? The GPX 4500 is not cheap.

  18. Johnny Armani

    Hey Mark, thanks for the info! While I was looking up some of the gold metal detectors you recommended I came across the Bounty Hunter brand of metal detectors. Do you have any experience with? They seem to be even cheaper than the Fishers but do they do the job?

    • Marc McDermott

      Hey Johnny. The Bounty Hunters are moreso for kids and folks that go detecting like once per year. I wouldn’t use for gold. Bounty Hunter and Fisher are the same company, just serving different markets.

  19. Gary

    A good Article you have there.
    I live in Western Australia and prospect with a GPX 4500…my last trip 110 pieces in two weeks, I would be rich if I could find a detector which discriminates better any suggestions?
    I am also developing my own coils…very small 3″ to get in amongst the bushes… I used a minelab probe at one point but the snakes did not like me probing them in the bushes so I need to be further then arms length.
    regards Gary

    • Marc McDermott

      Thanks Gary. I’d stick with Minelab for all things gold.

  20. Maddox

    It helps a lot just wanted to say thank you very much for taking the time for people you don’t even know. Your the man!

    • Marc McDermott

      Thanks Maddox!
