Review by Fran on June 21, 2020I've owned this Machine for about 7 years now. This GMT detector is so accurate and sensitive to all targets that it is like an extension of the user that's holding it. You can determine the target and depth with the signal response after a little experience and getting the feel of the machine. The screen reports to you the target ID and is spot on accurate which helps illuminate digging trash and is always spot on. Best mid range detector for hunting the Gold.
Review by Cody on January 19, 2017Well, yes, there were some detectors that were hard for me to use. Trying to tune this detector was simple. It just took a little help from my friend. It was easy after that. There are different features to it that turned me on to this detector. The features on this metal detector that I like are that they are lightweight and compatible. They are really strong. My friend had his for 10 years and dropped it several times. They are very good reliable detectors. If you are a coin hunter or meteorite hunter, this is the detector for you. Other White's products can have the same effect as this one. This will detect gold but if you really want to find those BIG NUGGETS, then I would recommend the Spectra V3. My typical find is gold coins and jewelry and small gold nuggets. I would recommend this detector to anyone who likes to find treasure. So get out there and find it. Good luck!
Review by Michael T. on November 9, 2016This detector is very user friendly for the novice or expert. My only complaint is that the scale that detects a percentage chance of a trash / metal target is 100% correct all the time and I dig all targets. So I have to start trusting that scale more to dig less junk and spend more time chasing the gold. I highly recommend this unit especially for the beginner that can afford it. The auto-mode is a no-brainer and you will find gold!
Review by Richard E. on July 11, 2016This is an excellent model for finding gold in the desert. When the GMT indicates a high level of black sand. Set up your dry washer and run two or three buckets. Then pan it out to see how much gold you have. I have found small nuggets to the size of a grain of salt. It hasn't failed me yet.
Review by Anonymous on April 15, 2016Hi, I've used both units extensively and still own both. If I want to hit the smallest gold possible, I'll be using the Gold Bug 2 with a 6" coil. The GMT is close but the GB2 has the edge for small gold. However, the GMT gets much better depth in hot ground on large nuggets than the GB2. For overall performance I think the GMT has a better balance of both small and large gold performance. I'm generally willing to pass on sub-grain gold to get better depth on larger gold. I'm not saying the GMT will not hit sub-grain gold as it will quite easily. I'm just saying the stuff I can get with the GB2 that the GMT can't is very tiny indeed. I guess which raises the question of why I'd care to use the GB2. Well, when checking hardrock quartz samples even a flyspeck can indicate rich gold ore. When using the detector as a replacement for a gold pan, again, even a flyspeck can tell me I might want to set up a highbanker. The GB2 excels at these uses. They both have dramatically different iron rejection capabilities, both with pluses and minuses. The GB2 uses a iron rejection system that basically ignores iron targets. The GMT always signals iron, but indicates via a meter the probability the item may be ferrous. If the probability is high enough, you also get an audio indication. The issue is that in many soils a very small or very deep nugget at the edge of detection depth will often signal as iron. If you have the iron disc engaged on the GB2 and pass over such a nugget, the machine will ignore it, and you'll never know anything was under the coil. So the smart way to hunt with the GB2 is to hunt in all metal, then engage the disc to check the target. If it reads iron, knock off some soil and try again. If it still reads iron, it probably is. But in some rare cases the target that initially read as iron will now read as non-ferrous. The problem in really trashy sites though is that it is tempting to just hunt in iron disc mode. I've done it myself.
Review by Larry R. on March 16, 2016I have been metal detecting for about five years now, and I've used many different types, from Bounty Hunter to Minelab. I now own a White's GMT DD and if you hunt for gold you can't go wrong with this detector. It's pretty much a turn on and go detector. The most useful feature in my opinion is the auto ground balance. I just turn it on, pump the coil a few times, and wallah you're all set to start detecting! For those of you who like to manually adjust your ground balance; this is the easiest machine I have ever had the privilege to operate. The second nice thing I like is the iron discrimination. I have found that when the White's GMT DD tells you there is a 70% or more chance that your target is iron, it really is! I usually wouldn't dig a target with that high of a percentage, but with anything less you better believe I'll start digging.
The White's GMT DD is very user friendly and also light weight. It only takes four AA's batteries while still lasting many hours. It hasn't failed me yet, but I always take extra batteries just in case it finally runs out of juice. I live in the desert and my main hobby is detecting for gold. The penetrating power of this detector is amazing! It has detected some tiny nuggets that I didn't think were possible to get a signal from, but they are in my gold vile and seeing is believing. I have also picked up some nice size loud and clear nuggets, a mercury dime, and even an old Army can dump (along with some of their can openers and such.) So, if you are in the market for a gold detector and then some, White's has priced this detector within reach for a lot of us folks that can't afford a $4000 detector. You won't be disappointed.
Review by LMeidl on November 14, 2015I researched detectors for quite some time before buying the White's GMT. If you're looking for gold nuggets (even super tiny ones) this detector will do it. In this price range you really have 2 great choices... the Fisher Gold Bug Pro or the Whites GMT. Don't expect to use this at the park for coins or rings, as it is a nugget shooter and will have you digging every pull tab and bottle cap in the park. In my testing, it picks up nuggets as small as 0.30 grains (not grams, but grains... way smaller). You need to read the forums to fully understand the setup, but it is worth it. Good luck hunting!
Review by Mike C on February 4, 2015I have owned several White's metal detectors capable of finding gold. They were the 4000 D, 6000 DI Pro, and the Goldmaster Series 2. They all did an excellent job of finding gold, went fairly deep, and could pinpoint precisely. I paid for these machines many times over with the gold they found for me. Now I own the GMT, which is an excellent machine. It will locate pieces of gold almost too small to even worry about, detect very deep, and will almost eliminate the chore of digging iron. There are almost too many good things about it to mention here. BUT... this machine cannot pinpoint anything! It does not even have a pinpointing program! It takes forever to locate a small gold nugget and requires digging a large hole and detecting for the target by the handfuls of dirt. Forget trying to pinpoint a coin in a park, the size of hole you must dig would get you kicked out in nothing flat! White's... what were you thinking by not putting pinpointing capability on your best gold machine??? Huge mistake!!!
Review by Mark K on May 28, 2009I purchased my Whites GMT from Kellyco a few months back when my other gold detector quit working. I spend a lot of time nugget shooting all over the U.S. so I needed a good unit. That's why I went with the GMT. I have friends that use the GMT so I knew what it was capable of. It's easy to use and it helps you find the gold better than some gold detectors I’ve used that cost a lot more. I recently took my GMT on a nugget shooting trip and came home with over 2 oz of gold. I would definitely say if you're looking for a good unit for prospecting that's easy to use and reasonably priced the GMT is a good choice.
Review by James P on April 8, 2008My White's GMT has been reliable and easy to use. I did read the entire instruction book that I got online before my detector arrived. I also used it the first few times I used the GMT. The battery life is amazing, the batteries last a very long time. I live in a remote area, so the headphones are not needed, but help and keep your ears warm in the winter. The interesting feature about this metal detector is that you can track black sand. In my creek, the smaller gold is unusually in or under black sand deposits.
The operation is simple, and I found it does balance well. We have lots of hot rocks, I mean lots. I think the worst obstacle for me had been getting past them. I know this will come with experience, but I still want to dig. I found one 20 gram gold nugget on my property the 3rd day I used the GMT. I was told that someone 8 years ago found two 8 ounce nuggets on my little mountain, so there could be more. I would like to purchase another detector, one for treasure too.
I will probably get the one that shows what object is underground before you dig. I have had other metal detectors and they went through batteries fast. I can work for a couple of weeks easy using headphones and batteries are still good. It even finds gold! Have fun!
Review by Johnny M on April 3, 2008I can't tell you how many forum posts inquire what kind of mid priced metal detector prospecting enthusiasts should purchase for finding all types of gold.
The White's GMT was designed to do just that!
With a price that won't break your bank the GMT is a highly praised instrument. Equipped with headphone jack, external speaker and easy to read LCD screen the GMT is the perfect tool in the arsenal of the modern prospector. It is extremely sensitive to small gold so it allows you to find placer pockets and follow placer pay streaks with it's low profile, narrow, 5" by 10" DD coil. A unique quality of the GMT is to analyze potential gold targets by analyzing target iron content.
A lower percentage of iron in a reactive target raises the probability it's gold! The GMT will follow those black sand deposits so important to the prospector and analyze their iron content and alert you when there is gold! I have detected gold down to half a flake with my GMT and the it goes wild for single pickers. Troubled by those nasty hot rocks your GMT will help identify them and reduce your digging.
The ability to analyze iron content also make the GMT a great meteorite hunter. In the middle of a black rock strewn lava field near Stanton, Arizona I found my first meteorite as big a a lime. Another troublesome condition facing the prospector is ground balancing in high iron content soils. The GMT was designed to compensate for these conditions and excels.
I have used the GMT in the gold rush area of Northern California and as far North as the Nome region of Alaska and found the GMT quite at home in those high mineralized soils. Incorporating automatic or manual tuning features make the GMT a gold grabbing machine with excellent sensitivity to all sizes of gold with an easy to understand control box with startup presets.
The GMT is also economic to operate as you can receive up to 40 operation hours on 8 AA batteries that slide in and out of the control.
Review by David K on April 1, 2008Some women lose their husbands to other women, others to professional sports like football. Well back in the early seventies I felt like I was losing my husband to his new hobby metal detecting.
If he wasn't working or at home, which wasn't that often in the summer, he was always out metal detecting. He would come home day after day showing me what he had found that day. With stories about how he had almost missed a coin because it was so deeply buried or maybe because it was setting on edge and he wasn't getting a good signal.
When the bitter cold of winter set in and he was know longer able to use his detector he was like like a little boy who had lost his best friend. Through the winter I devised a plan that I thought would get us back together again in the summer.
I thought if you can't beat them join them! Unknown to him I took the coins and jewelry he had found that summer cashed them in and bought my own detector.
Thirty years ago detectors weighed six or seven pounds that didn't sound like much but within three hours my shoulder was killing me and I had to call it quits. As I walked off that grassy field I saw that I told you so look on my husband face. However the next day I was back out there even if I was sore.
By summer's end I could stay out as long as he did. Today most detectors are only two to three pounds. Until my husband had a stroke thirty years later up until then we were a common sight around town swinging our detectors.
We enjoyed coin hunting the best and have found that what they say about a place never being hunted out is true. We have come back to parks or old school yards years after we thought they were cleaned out and found more coins and jewelry. Until he had a stroke we bought a new detector whenever a new model came out.
Review by Butch N on March 17, 2008Presently I do not own a metal detector. I use one from a friend of mine. He has a White's GMT, and we nugget shoot. I find the GMT is easy to tune and easy to use. I really liked the fact that metal detecting, is not only fun, it also gives me the opportunity of getting out of the house. We have an area that we detect, with all of the research that we have done, from archives, and history, both factual and rumor. We have narrowed down an area of about one square mile. But right now there is about 20 feet of snow in the area, sort of hampers any kind of searching now. We packed in on foot in the past, but I think any further searches will be done with the use of mules, to carry not only us, but all of our supplies. The area that we search is high in materials that usually causes some machines that my friend has tried, to be hard to alleviate the background noise. Since he has gotten the GMT, it is easy to tune and balance the machine. We have found nuggets in the stream, that is the drainage for the area, that we intend to search this summer. I don't have all that much experience but for all I know of the GMT, I find it easy for a relatively new individual to this hobby, to operate the detector. I have and would continue to recommend this unit to anyone that will listen to me. Thank You.
Review by John F on March 17, 2008I purchased my White's GMT DD detector used, and it was made for Sears so none of the the names fit and I chose one under White's because they made this one. It was my very first and only detector but I loved it and it produced very nicely for this beginner. There are many old foundations around me here in NY and I found so many interesting items with this detector. Old pocket watches, lead toys, Indian head penny, 1907 quarter, horse bells, locket necklace, a bullet that didn't fire. As I said, so many different items and each one had my heart just pounding with excitement, YEEEE HAWWW LOOK AT THIS! I had so much fun with this old detector and it wasn't even a top of the line, just an off brand by White's. That is why I highly respect these White's people, thank you White's. Now for the part that I am really writing this for. I was at home one day when I got a call from a friend, he said (in a very concerned voice) John I heard you have a metal detector. This guy use to make fun of me and couldn't figure out why anyone would waste time with those things (he who laughs last LOL). He said his sister lost a very expensive ring while swimming in a pond and was wondering if my detector would work in water? I didn't know if it would but heck I was ready to make him eat his words if I could. Long story short - I put the coil into the water all the way up to the detector box and started moving it around when YEEEE HAWWW guess what? Beep beep and up came the ring. That day I became the hero for his sister and what a feeling. Thank you White's company.
