  1. GMT Tiny Nuggy

    Finally! Found with White's GMT and the 6" concentric coil. Couple grains, about 3" deep. Smaller foot was perfect for working bedrock cracks and avoiding giant hot/cold rocks in highly mineralized ground.
  2. https://www.whiteselectronics.com/product/6-concentric-gmt-coil-micro-tireur/ DETAILS Previously only available in Africa, this 6 inch “Micro Shooter” coil for White’s GMT has been made available for the general public as requested. It’s been called “The Patch-Killer,” “That French Coil,” or “I Can’t Pronounce the Name,” but tireur is French for shooter. If you are after every bit of gold in an area, this shooter coil belongs in your GMT’s arsenal. Specially-tuned for mineralized ground, this nugget-sniping loop is a beast on small gold. Coupled with the GMT’s high 48kHz frequency, it’s highly sensitive to the smallest flakes of gold your machine can detect. The small profile makes it ideal for detecting in brush or rocky hill-sides, and with the small detection window you can more easily pick through tailing piles and areas with bits of iron from past mining operations. SKU: 801-3250-1 $149.95
  3. Whites GMT & MXT

    Hello Steve I have a? I bought a gmt a 2008 e series from a brian that was at gains creek when you found a big nugget with a Mxt . I have an mxt 300 the gmt I got from him seems weak or not ad great as my mxt can you help it's an old gmt 2008 e series is there a way I can make it better. the brian from amds aka akmining he know you I want it to be better than my mxt
  4. I am very new, is there any way to tell the approximate depth the item you detected? I have a GMT.
  5. I've been planning on some testing of the GMT's ability to find paystreaks of black sand. Finally went down near the Utah border and collected some sand to use. I was disappointed in how slow the GMT's indicator changed over the sand I used. Much too slow, unless you want to die of boredom before finding any. That's probably why so little is written about it. It only works in "autotrack", too. I tried various levels of V-Sat, Gain, etc., but nothing worked in a way I'd spend much effort doing. But, I DID find something that works.` I put the GB in Manual, and cranked the GB as POSITIVE as it goes (99). That way, it only responds to REALLY strong positive signals, and most negative signals. I turned the THRESHOLD all the way down. At those setting you hear very little ground noise, but still get a good response on the black sand. The gain can be adjusted to ignore the general levels of blacksand on a bar, but still respond to a higher concentration of it. The response is fast, so you can run the detector as if looking for gold. Of course, you won't hear any non-ferrous targets at these settings...they're strictly for finding concentrations of bs. The concentric coils had a definite advantage over the DD, but I would have no problem using the DD for this. I was using blends of pure magnetite,or at least ALL of the black sand I used could be picked up with a magnet, mixed with sand that had no magnetic iron in it. I used both a 1:5 ratio of bs to white sand, and a 1: 10 ratio. Both were detected at nearly 4". I didn't try any ratios below 1:10, but I'm sure a ratio of 1: 20 would be detected, but might be only at shallower depth, depending on where the gain was set, and that would depend on the level of bs in the general run of the bar being detected. Another thing on the mixes used....I used a teaspoon of magnetite in each mix. Put them in sandwich bags, and spread it into a thin layer. But, to be fair, the coils could always see the entire teaspoon of magnetite, as the test blend, even spread out, was smaller than the area of the coil. All of the sand used was smaller than #50. I tried using the "learn accept" function on the DFX, but could make nothing work on that for finding black sand. Tried several different programs and settings, with complete lack of success. Jim
  6. Around the time the Minelab Eureka Ace Dual came out I found this piece near Sofala in New South Wales with a Whites GoldMaster. Neither my Minelab 16000 ground tracker or the Eureka Ace Dual can hear it and a GPX5000 with the new coils can`t hear it, but the 5000 with the 8" Commander can hear it at about 1". It sg`s at 13 grams gold but I`ve never believed there`s 13 grams in it. Most of the little pieces around it are connected electrically. cheers Dave
  7. I received this question via email, edited to remove any tips as to the source: "Steve- been reading your reviews of detectors from way, way back. Now I'm looking for a bit of advice. I've got a claim where I've pulled nice gold, but the biggest single nugget has been just about a gram, pretty small stuff (but it's pretty plentiful). My GB-2 has really shined in this environment - shallow bedrock, low mineralization, and plenty of small gold. The issue is that my son doesn't want to let me use the GB-2, as he wants to use it all the time. That puts me in the market for another VLF machine. I've tried the GB-Pro, and didn't really care for it. Your review of the Nokta AU Gold Finder, and the Makro Gold Racer, both look pretty good. Other than the display and control box itself, are these machines really the same, or would one do better (coil size being equal) than another on small gold with low mineralization? The reason why I just don't go get another GB-2 is that it would be a nice bonus to use the new detector close by my son, while still hopefully having it excel and finding small gold. Any insights would be greatly appreciated. If there really isn't anything else that comes close, then I'll certainly go for another GB-2, even at it being as old as it is, but if there is another one that would excel in the above environment, I'd certainly appreciate your opinion on it." Well, in my opinion the 71 kHz Gold Bug 2 with 6" coil has been and continues to be the top of the heap when it comes to finding the tiniest bits of gold. So the real question is whether you feel like giving up that little edge the unit has over all the rest in order to run a machine right next to your son without the two machines interfering. You also have the advantage of being very well versed in the use of the Bug. Let's assume you do want to get something else however. You have mentioned the 56 kHz AU Gold Finder and Gold Racer, and they are indeed the same circuit in two very different packages. Coils from one will work just as well on the other. Other current new model alternatives would be the 48 khz White's GMT and probably the very soon to be available 45 kHz Minelab GM1000. Finally, I should mention the XP Deus V4 high frequency coil options hitting the market now in case you might consider a more exotic option. There also have been hints of a dedicated gold machine from XP this year. I would assume a small coil as being a must have, and an advantage with the Gold Bug 2 is you can get it with the small coil as a stock variation. So let's compare internet prices. Fisher Gold Bug 2 with 3.25" x 6.5" coil = $764 Makro Gold Racer with 5.5" x 10" coil $699 plus 4" x 7.5" coil $119 = $818 or Pro Pack $899 Nokta AU Gold Finder with 5.5" x 10" and 5.5" round coils = $999 White's GMT with 6" x 10" coil $729 plus 4" x 6" coil $127 = $856 Minelab GM1000 with 6" x 10" coil and 5" round coil = $799 A Deus runs $1250 plus the 4.7" x 9.5" elliptical HF coil at $425 = $1675 so not a good fit here for price and no smaller coil option than the elliptical. The only hope of that improving is if the dedicated gold machine shows up with the HF coil as stock. I have to admit that the reports of warranty issues with early Gold Racer models have me concerned. This despite the fact I have what must be the oldest Gold Racer and AU Gold Finder units in the country, and both are going strong. I have to assume the issues, whatever they were, have been ironed out. I don't know that for a fact however. If you got one and still had a problem, Nokta/Makro is famous for resolving issues with customer satisfaction. The units carry a two year transferable warranty. The GMT is the safe tried and true made in the U.S. option, and as far as performance the 56 kHz Gold Racers and 48 kHz GMT run neck and neck. The big unknown at an attractive price is the 45 kHz Minelab Gold Monster 1000. My best advice - wait! The flood gates are just now opening as regards reports on the GM1000 and at $799 with two coils it looks on paper at least to be an option worth waiting to find out more about. If you have to do something this minute, the GMT is the safe option if the reports of problems with the Gold Racers worry you. Personally, I have been very happy with my Gold Racer and would not trade it for a GMT. I have to note I finally did get another Gold Bug 2 with 6" coil however. If you are the sort of person who can't live without having that last small edge of performance, it is still the machine to beat for tiny gold performance in milder ground like you are describing.

  8. Been getting into macro photography, here are some close-ups of nuggets found with a GMT in Northern California by the factory's own Steve Howard. What's your best nugget picture? Interested in seeing different photographic techniques... might steal some ideas from those with more experience. I know "size matters" so having a reference like a US Quarter is good, but I think there is a lot of beauty in seeing just the nuggets - texture, structure, color, that sort of thing.
  9. Steve, I still have my old White's Goldmaster V-Sat. It's the same one I used when we hunted together at Crow Creek. I have two coils for it, the original coil it came with and the very small one that is used for tight places and bedrock. This is the coil that White's first put out when we lived in Alaska, small and black with no markings on it. Steve Houston introduced it when he came to Alaska on his promotional trips. I don't use the original one because I find it impossible to ground balance with that coil, so I am limited to just using the small one. That's ok by me since most of my limited and sporadic nugget hunting is in bedrock areas. The problem I am having is that I constantly get false signals and lots of other noise whenever the coil comes in contact with anything. If I bump rocks or brush, or if I even brush it up against wet grass it will false signal. this makes it impossible to "scrub" the ground as you advise people. I am wondering if this problem might be in the settings on my control box, perhaps I am choosing the wrong settings? I have tried just about everything I can think of, but it does this all the time and is very annoying. Is there anything that you can think of that I may be doing wrong?
  10. Thought this was a good tip on using a detector like the GMT in conjunction with traditional techniques. Just need a machine that can track black sand to locate a paystreak, mark the deposit with stakes and start processing material. Horrendous 144p resolution (filmed with potato) but info is solid!
  11. I was surprised, never having run a high kHz machine before, I nearly went off the road at first! Got my machine last week and got to hunt about 6 hrs. this weekend. Got skunked but was happy I got the feel for the machine and kept it on the road. I really got to see the difference between my PI machine, my AT Gold and this GMT (my red hot poker). This is the first time I've had two VLF machines with kHz ratings this far apart and the first time running 48 kHz. I'm laughing about it now. I was totally caught off guard and figure I might have been a little to cocky, so it makes me laugh. Another life lesson learned. And, I picked the river where I knew the hot rocks covered the bottom, shallow overburden and lots of exposed bedrock. So, how's that for cocky? So, I went up the river hearing, boing, boing - boing, boing - boing, boing - Ha! I loved it! (I was thinking, "I know you and.......I know you and.......I know you"! One thing I found concern with is, the Thold wouldn't run smooth till I turned the gain to 2 - 2 1/2. I need to do some testing to see how much I am losing by having to do this. Are there other tweaks to smooth the Thold without losing gain? It was a beautiful early fall day. Clear sky, light breeze and in the 70s. It was a great outing and the first outing with my GMT. So far, so good.
  12. that will enhance it's character and performance. Thanks for any help.
  13. After reading a quote from Steve that older VLF Detectors will perform much the same as newer ones (just without some bells and whistles), I jumped and got a Goldmaster 4B for $250. I know the adjustable frequency control is there for the detector to play nice with other White's Detectors in the area. Has anybody ever (to y'alls knowledge) ever modded one for a lower frequency range so that it would (conceivably) go deeper? One of the popular mods for a Minelab SD2000 was to add extra frequencies so it would perform better on smaller nuggets. I would be interested in going the opposite way on my Goldmaster. Any information is greatly appreciated. Thanks - Mike
  14. Hi, I read your opinion of the gmz, will it do the job or not?
