The GMT is a great machine but...........
Review by Mike C on February 04, 2015
I have owned several Whites 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! Whites.......what were you thinking by not putting pinpointing capability on your best gold machine??? Huge mistake!!!

I 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.

My 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 1 20 gram gold nugget on my property the 3rd day I used the GMT. I was told that someone 8 years ago found 2 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!

I 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 excells.
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

Some 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.
