Great Detector and Great Service

Review by LMeidl on November 15, 2015

I 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!

The GMT is a Great Machine But...

Review by Mike C on February 04, 2015

I 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!!!

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.

Review by James P on April 08, 2008

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 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 04, 2008

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 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.
