Hi, 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.

I 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.

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.
