  1. Please try to stay on topic folks. This is one of those threads that might get the “cleanup on aisle 5” treatment later on once it runs out of steam. Just a FYI I sometimes clean up old threads that way for archival purposes, so people finding them later don’t need to wade through the off topic stuff. It’s like reading two separate threads mixed together, or listening to two conversations at once. If I can I split stuff into separate threads, but sometimes it's just random commentary. Not a huge deal, and if people want to run off topic I don’t go worry about it most times, but people who post off topic should also never expect their posts to last for eternity. My sensitivity to the issue varies with the importance of the subject, and I consider this to be one of the “subjects for serious, sober discussion”. The SD2000, SD2100, SD2200, GP Extreme, GP 3000, GP 3500, SDC 2300, and GPZ 7000, all had/have a built in warble that could be interpreted as an unstable threshold. So does the GPX 6000. Only the GPX 4000/4500/4800/5000 could obtain a rock solid threshold under normal circumstances. In my case, my GPX 6000, to the best of my recollection, seems no worse, and maybe better, than the SDC 2300 when it comes to threshold. Then on occasion it gets worse than that. On average, in an 8 hour day, I might apply the EMI cancel about a half dozen times. I am not normally in areas where there is EMI, and I think the issue is internally generated in some way by the software going off track. This seems to be related to using the external speaker, so perhaps a feedback loop in the circuit, or the software seeing the magnetic field generated by the speaker magnet/circuit? Long story short after 48 years of detecting I don’t hear metal detectors so much as make them an extension of my ears and mental audio processing makeup, and I think this does differentiate me from other detectorists at some level, as I seem to hear things others miss. I have a high number of what I refer to as “imaginary signals”, signals so faint I don’t actually hear them so much as experience them at some gut level. I do think we are all wired differently to some degree, and I think listening to detectors for 48 years has tuned my audio processing brain circuit in the way a violin players skills are tuned through decades of practice. I always ran my GPZ 7000 maxed out and noisy, and treated the noisy threshold as a threshold in itself, compensating with relatively low volume settings. I use the GPX 6000 external speaker a lot, and when I do, I run the unit at the lowest volume setting. My brain does not mind a noisy threshold, in fact in some ways I prefer lots of audio feedback, as it keeps my brain focused on the audio. If a threshold is dead silent, I will lose focus, and so I very much prefer a faint threshold. Noise is tolerable to me as long as it is consistent noise, as my ear rapidly calibrates the noise level as “normal” and just part of the threshold itself. I am highly tuned to abnormal signals, things that break the norm, whatever that may be. So what drives other people crazy, I do not hear at all. My perfect machine runs a threshold, with the machine hot enough that there is continuous faint ground feedback, and my ear “rides the threshold” looking for signals that break whatever norm is established through use. So it’s a hard subject to describe in words as I do think we all have a genuinely different experience of what constitutes noise. Some people can’t tolerate any threshold at all, and have to run silent. I’m at the other far end of the spectrum. So again, the several SDC 2300 I had all had the “Minelab warble” familiar to people who ran older Minelabs. My GPX 6000 normally runs at least as good, and I’d say better, than a normal SDC 2300. Yet it is never as rock solid as the other GPX models. Then, maybe a half dozen times a day, regardless of external EMI sources, it just seems to go off track. The EMI cancel may settle it, or may need to be applied twice, even three times in the rarest cases. I’ve recently switched more to just doing a full reset, but have not done that enough to know if it’s any more effective than the EMI button. I think many people are experiencing genuine EMI issues, and seriously, that’s a different problem. The machine is super sensitive, and I would expect EMI sensitivity to be part of that mix. What I am experiencing and describing is more something I think is inherent in the machine and it’s processing, like a software glitch. I’m not swearing to that, but it’s my best gut feel about what I’m seeing in the field in areas where genuine EMI simply can’t explain what’s going on. Overall, I consider the issue a minor annoyance at worst for me personally, so don’t what to make it sound like more than it is in my personal situation. But I do think there is something going on, and it’s not impossible it varies by machine. Toss in genuinely experienced EMI, bad coils, and peoples different tolerances for even normal noise, and it’s a hard issue to get a full handle on.
  2. My 6000 is working just fine also, but that does not mean that many are not, and it does seem to be more than just a detector here and there. Issues in any new equipment are to be expected…. that’s why we have warranties. But there does seem to be more amiss with quality control on the 6000 than just the oddball unit. https://www.prospectingaustralia.com.au/forum/viewtopic.php?id=37305 https://www.prospectingaustralia.com.au/forum/viewtopic.php?id=37186 The 6000 is not a lemon per se, but it seems many individual units might be. It’s got me feeling kind of lucky mine has been purring along so well. It does suck, because a good running 6000 is a joy to use, and I hate seeing so many peoples day end up ruined by a bad out of box experience. It’s like opening a gift and finding a lump of coal. Again, this is not a $300 detector, but one of the most expensive consumer level detectors ever sold. That in itself sets the bar higher than might be the case with an inexpensive detector.
  3. They are at it again - here is your chance to be a star! Hello, I hope this email finds you well. My name is Rhys Towse, I am a Producer at Raw TV, in London, we are the producers of Discovery Channel’s GOLD RUSH. I’m getting in touch with you today as I am currently looking to speak with gold miners to appear on A NEW TV SHOW! We are looking for small mining operations based in either the lower 48, Yukon, Alaska or British Columbia who are relatively green to the mining game and hungry for gold! Do you know any young gun’s out there mining? Or any old-time miners whose son or daughter is taking on their own small operation for example? Ideally, they would: have been mining for at least 1 season have a crew of at least 3 an existing camp set up with their own heavy equipment in place including, wash plant, excavator etc If you know of anyone who might be interest it would be incredible if they could fill in an online form here: https://www.raw.co.uk/takepart/2387 , Also is there any chance you might be able to forward on this email to anyone you know who might be keen to talk to us about this opportunity? Thanks, Rhys
  4. Spot on Jen. This is the Achilles Heel of the GPZ 7000 and GPX 6000. Both detectors bang hard on certain hot rocks, generally the same hot rocks, that prior Minelab models can either reduce, or eliminate entirely. Usually in my case they are rare enough that digging them is more annoyance than problem, but if you get into locations where you hit them every few swings or more, they can pretty much shut a person down. That's why to this day I still advocate the GPX 5000 as the machine for all locations and situations over these two newer models, as it is in my opinion the most versatile Minelab PI made still. The SDC 2300 is also great, but more limited in coil selection and settings, so I give the overall nod to the 5000. In any case, I wanted to highlight your comment, as the newer GPZ 7000 and GPX 6000 get a lot of positive commentary from lots of people, including me. But it's important to note that for some locations they can be a total fail. There still is no one perfect machine for all situations, and may never be.
  5. I'm very sorry for everyone experiencing issues with the 6000. This plus rod and EMI issues take the shine off the machine. There are way too many production issues with this very high priced detector. Not a good look Minelab. People expect more at this level.
  6. I’m not trying to argue with you, and if you want to believe that everyone that buys a nugget detector is finding lots of gold, that’s fine by me. It’s certainly what the manufacturers want everyone to believe. Just buy one, run right out, you’ll pay for it in no time, be making money fast. Yup, that’s the ticket!
  7. When there is not a single beep left. If I spend a solid day on a location, and can’t find a single target, including trash, I’d call it done. As long as a bit of trash remains, I figure there is still gold. I’ve never had a location go completely target free yet though, so at this point there’s not one of them I’d not give another go. New detectors has a lot to do with that. As soon as I have a new machine, all the old places just got a new lease on life.
  8. Actually it’s pretty easy to generalize if you are in retail and deal with thousands of customers. The vast majority of nugget detector owners in the U.S. are hobbyists, and most find little gold. Out of all the people in the U.S. who own nuggets detectors right now, the number who find more than an ounce of gold a year is a very small percentage. The people doing very well are the rare exceptions. That’s not speculation, it’s a fact.
  9. What you see is not what others see, but based on your browsing history and what Google thinks of you. They pay the website bills, and if everyone blocks them, eventually the forum closes. I love you all, but not enough to pay money to visit with you. The time I invest in upkeep is one thing, cold hard cash another.
  10. Great post Gerry. I see two basic types of gold nugget detectorists. The pros can be illustrated by the couple Aussie posts above. If you are seriously out detecting for gold, with a desire to make money at it, you’d better be focused on WEIGHT, and weight comes mostly via staying in larger gold. That honestly is less about the detector, but more about genuine prospecting skills, and forging your own path. Many models do well on the larger stuff, and for some a GPX 5000 may still be a better solution than the newer rigs, just for coil selection, and tuning options. Or a newer model, whatever suits your gold and ground. I genuinely appreciate you guys and what you do, but what follows is aimed more at the U.S. detectorists. My apologies to you few U.S. pros. You know who you are… keep going for weight over nugget count. No need to ditch a GPZ or even GPX 5000 for a 6000 if weight is your goal. The main U.S. market at least, tends to be more hobbyist oriented, and about relentlessly pounding old locations. The big gold tends to go first, so it’s been an arms race with new Minelab detectors, each generation getting better at generally hitting gold previous generations have missed. Some big gold still gets found, sure. The GPZ 7000 in particular hit smaller types of gold or specimen gold very well, while still retaining major punch on big gold. But most people just want to go home with some gold, any gold at all, and after GPZ the big stuff is getting very thin in many common locations. The GPX 6000 seems to deliver the performance one might expect with a GPZ 7000 and a smaller X Coil. The SDC has an advantage in tuning out certain hot rocks, but it does miss a class of gold that the GPX 6000 hits. There are some rocks, you tune them out, you lose gold. So a GPZ or 6000 is a mixed blessing in that regard. If you have a serious hot rock issue, and still want tiny gold, a SDC is a great solution, but don’t think there is not a cost associated with its aggressive hot rock cancellation. That, and limited coil options. For tiny gold and specimen hots, seriously giving all but the hottest VLFs a run for the money, the 6000 is optimized to hit gold that both a SDC and an unmodified GPZ will miss. That does mean more hot rocks, but frankly I’ve not found a place yet where I can’t deal with them, mostly by ear and by eyeball. If digging a few hot rocks means I get gold others missed, I’ll do it. If I really put the pedal to the metal, my 6000 will hit small gold about as well as the 19 kHz series VLF detectors, assuming similar coil sizes, but with more punch. So like GPX 6000 versus Gold Bug Pro with 11” coil, well, except for trash handling, the VLF can now stay home. It’s only the 48 kHz and higher models that can hit tiny bits I miss with my 6000, but I am talking sub-grain bits. 480 grains to an ounce, and bits less than 1 grain. Say 10th of a grain or less. To make an ounce, you need to dig 4800 1/10th grain bits. That’s a lot of digging, and frankly, for that stuff, it’s maybe time to break out the dry washer. Gerry asked me early on about specimen gold and the 6000, and my answer was not to worry. The 6000 is probably the best PI made to date for specimen gold, and I’ll post some of my finds in that regard soon. It may very well be my new “thing” with the 6000, hunting pocket gold. Dispersed gold in rock is just another version of small gold, and the 6000 with 11” mono kills it. But I digress. Long story short, I’m not surprised your customers are seeing the number count go up at Rye Patch and other locations. I’ll offer some advice for that. People with VLF skills have an edge with the 6000 and tiny bits. Main thing is SLOW DOWN. Speed kills the 6000, it’s not a fast swing machine, and those in a rush to cover ground will miss the tiny stuff, and big stuff at edge of detection depth. “Small signals” not small gold. I’ve been bouncing back and forth between manual sensitivity max at 10, or Auto+ with threshold on, and have yet to decide which is best. I don’t think you can just go with one, it depends on the ground. But mild ground, I’m currently favoring Auto+ with threshold on (hold ground rule button 4 seconds to engage threshold on in Auto modes), as the auto sensitivity can push above manual ten in the right conditions. Just remember in some ground, it will also auto adjust lower than 10 manual. There is not a cut and dry answer, you just have to try both. Then slow down, and get your tiny signal ears on! Only improvement I can see would be a 8” round mono, or 6”x10” mono, both for tight locations, but also because they enforce the slow down rule. Overall however, I’d still probably stick with the 11” mono myself, as being best on the small stuff, while still having max punch on up to 1/4 oz type nuggets. 17” mono for covering ground/patch hunting, plus more depth on larger than 1/4 oz gold. Rod twists, and some warble now and then, whatever, this machine is deadly in my hands on my ground. Your results may vary, but I’ll selfishly admit that’s not a major concern for me. I’m about done for the year, but am looking forward to ramping things up next season, hunting places I’ve never hunted before. No more pounding old locations, it’s time to make one last big find before I simply can’t do this stuff anymore. In two years I’ll have been detecting for 50 years, a half a bloody century, and the GPX 6000 is definitely putting some new spring in this old detectorists step.
  11. Not enough discussion here anyway, so it’s got that going . I’ll go with the optimistic view that they are waking up, giving website at least a little attention (they should put new product like the 12” coil up, one would think), and maybe getting ready for new product for 2022. I’d still like a proper Impulse Gold, if such a thing is ever to be. The Impulse AQ is interesting, but in my ground a properly functioning ground balance is more important than an attempt at PI discrimination. Any new single frequency I really don’t care about any more. FT has some great single frequency models, and we can mostly all agree that anything new in single frequency is just a remix of something old. The tech is maxed out. CZ going away does however imply to me a new multi on the way. It’s not a secret one was in the works for years (CZX) that finally ran into a development dead end. But they are bound to have picked up where that left off, and I do think the CZ being discontinued means we will see something in that regard. So maybe a new multi, a genuinely finished PI or two, and hopefully a full website revamp. The discontinued models need to be archived, and replaced with the new lineup.
  12. The Minelab E-TRAC, Safari, Explorer SE Pro, Explorer SE, Explorer II, Quattro MP, Explorer XS, and Explorer S can all employ the same coils.
  13. Unfortunately, with Minelab controlling coil sales via embedded chips, this is unlikely, a loss for both Minelab and their customers, in my opinion. I’d buy one for my Equinox in a heartbeat. Oh well, can’t have everything, but at least lots of other detector owners will have the option, including the older BBS and FBS owners.
  14. The Time Ranger Pro is a F19 with new stickers, so yes, these coils will work. The coil they list for the 19 kHz G2, will work on the G2+ of course, plus F19, Time Ranger Pro, and all Gold Bug variants except Gold Bug 2. Coils made for the AT Pro should also work on the AT Gold and AT Max, just like Garrett AT coils work an all the versions. As long as they correctly match the AT spec, that is. The F75 coils should also work on the Fisher F70 and Teknetics Patriot. Once you add all the variants up it's a long list of models. Detech should compile the complete list just to be clear for people. For reference, here is the Fisher and Teknetics Coil Compatibility Chart
  15. I have the Bigfoot for DFX, which was what it was originally designed for. The figure 8 winding has built in EMI cancellation properties, making this coil actually deeper in some areas than more conventional coils, as it eliminates "silent EMI" issues. But the big advantage is pinpointing. The DFX cuts out the rear half of the coil, so only the front 9" works when you hit the pinpoint trigger. It works so well you hardly need a pinpointer at all. The Bigfoot coil, being a figure 8 winding, has a reversed polarity front to rear. The DFX corrects for this, but the MXT and M6 do not, so you get reversed signals front to rear on MXT and M6. They work, but this takes some getting used to. But for the DFX, it's a real dream coil. The DD does have a couple advantages over a figure 8. There is a relative weak area in the middle of the figure 8 winding, where the coils cross. The DD does not have this issue, with a consistent signal front to rear. So MXT and M6 users will see an improvement in front to rear signal consistency, no signal reversals, and no dead spot. This polarity reversal would be an issue also for Garrett, Minelab, and Fisher owners also, so realistically DD is the only option for general sales. Fisher, Garrett, and Minelab users, well, all I can say folks, this is a coil well worth consideration, an option you've not had up until now. It is 4" wide so depth is more like a 4" coil stretched out, not like an 18" round coil. Though it's a little better than that actually - in surface area you are getting more than a 4" round for sure. But really the name of the game here is coverage, and if you get used to one of these for walking a huge beach, sports fields, etc. smaller coils start to seem snail like. Jewelry hunters- just get one!
  16. I have been lobbying for over 6 years - more like a decade - for somebody to produce a replacement for either the White's Bigfoot, or Tesoro Cleansweep coils. These narrow 18" long coils are superb at scanning large areas for relatively shallow targets, making them excellent for jewelry detecting in large fields, and for vacuuming up recent coin drops. They are so efficient at this that some planted coin hunts prohibit them as an unfair advantage. Also great for beach detecting recent drops, relic/coin hunting huge fields, patch hunting for gold nuggets, even meteorites. See my long thread here for details on the subject. The short story is that the Bigfoot was a 3" x 18" figure 8 wound coil, specific to some White's models. This design has advantages, but is very hard to make, pretty much a hand made coil. And to really work best, a detector needs to be optimized for it (see additional post below). Barring some process breakthrough, I expected getting this coil back into production to be difficult at best. I therefore also concentrated on the Tesoro Cleansweep design as an option, as it is simply an elongated DD coil, much easier to produce properly in volume at lower cost, and with no oddball operating characteristics. I tried to get Nokta/Makro in particular to make these, as they are generally open to new ideas, and I thought, and still think, a detector sold with this coil as stock would be a unique offering that would attract attention. That came to naught, unfortunately. Then, about a year ago Detech contacted me on another subject. I used that opportunity to once again bring up the elongated coils as an ignored market, and they seemed enthusiastic about pursuing it. But then nothing, silence for a long time. I pretty much gave up hope. I was contacted by another old detectorist on the subject recently, and said just that. I had lost the original contact info from Detech, and was resigned to these coils never happening again. And frankly, I have one, so I'm covered. I just wanted so much for others to be able to get their hands on these coils, especially for machines that never had them as an option. Well, miracles happen!! I just was notified that Detech is producing a 4" x 18" DD coil that will be available soon (not sure how soon, but they may chime in on this thread hopefully). I do not know the weight or price, but with Detech I am sure that the price will be reasonable. The best part is that it will be for more than one brand of detector. The list I was just provided with: - MINELAB'S EXPLORER / E-TRAC / SAFARI - FISHER'S F75 - TEKNETICS T2, G2, GAMMA / OMEGA - GARRETT'S ACE AND AT PRO - WHITES' DFX / MXT / M6 And so without further ado, let me give you your first look at a genuinely new product for some detectors, the Detech Arrow! One of my favorite all-time coils is the Detech Ultimate series, so I know they make some great coils. This is a niche coil, but one many people crave. I want to give a very personal thanks to Detech for doing this, as it is something I have tried hard for a long time to get somebody to do, and they have granted this old guys wish finally. Thank you!
  17. No worries here. I think a lot of the time manufacturers think we are just bitchers and complainers. I have been quite critical of all the manufacturers at one time or another. On these forums at least, there is more to it than just tossing rocks. Most of us genuinely love metal detecting, and we really care what is happening in the industry. We first get frustrated, then even angry, when we see these companies making stupid moves. The U.S. companies in particular have been drowning in arrogance. I’ve watched for very many years in frustration, while Minelab, once an unknown upstart from Australia, has eaten all their lunches. They’ve seemed completely blind to what had been very obvious to me for a long time… that Minelab was literally going to put a few of them, if not all, out of business. Then along came Nokta/Makro to add extra pressure. They are lucky the Chinese were asleep forever, but Quest is just the first that will add even more pressure. Tesoro did not even try, just committed willful suicide by doing nothing. White’s tried, but woke up just a little too late, and now they are gone. First Texas is just a mess, but their volume in low end big box product has masked this. To me they are in more trouble than they seem to think. Their mind share with most of us is evaporating, if not already gone. Just like White’s, there are the faithful who stick with companies to the end, but most of us have moved on. If they think cranking out cheap units for Walmart will keep them alive forever, they will learn that never works, never has. The irony is they bought Fisher and Teknetics to try and escape the Bounty Hunter low end trap, but in the last few years they’ve let both those premium brands languish, if anything gutting them to give their best products to Bounty Hunter. It’s not that they have not been trying, but their efforts have floundered, or been misdirected. The marketing is a non-cohesive disaster, almost non-existent. The main efforts seem to go into placing pallets of product at Costco and taking care of their big box customers, not taking care of the small dealer network. The Fisher website, as has been noted, was downright embarrassing in its non-updated, neglected state. It perfectly encapsulated my view of the company… just an ad hoc, sticking fingers in leaking dams approach to the business. Sounds like I have it in for them, but just the opposite. I probably care more about the company than many people that work there. Detecting is my life long passion, and I find it almost offensive watching the U.S. manufacturers run their businesses into the ground through arrogance and neglect. Mainly arrogance. They all think they are so damn smart, and that people like us are just unfair critics or idiots. No, many of us just see what they don’t, brands we know and would love to support, but who simply don’t seem to care enough to engage with us, or listen to us.
  18. Yeah, it’s me, and the picture is real. It was cold (was snowing earlier in the day)…. I was wearing a coat for that. Try doing Tahoe at 40 degrees with a stiff wind, and I suspect you’ll wear a coat also. There was a group, and we had diverted from a planned nugget hunt due to snow. I used what I had in the rig, my pick magnet to recover the small ferrous trash, and dig / recover targets. Not my preference, but it worked for me under the circumstances. In fact, nugget hunting techniques work rather well for hunting micro jewelry, the type that drops through most scoops. It was not a posed photo shoot, though I did shoot some video tips on the 24K at beach because, yes, it’s a great small jewelry machine. This photo was shot by somebody when I was not even aware of it, and they decided they liked it well enough to use it anyway. Sorry I’m not the typical faked gal in bikini photo. Not royalty for sure, just an old guy in a coat with a pick. Regardless, let me remind everyone this is the First Texas Forum, and bringing up other brands is as welcome here as bringing up Chevy on the Ford Forum. If you want to get into brand versus brand stuff, we have a forum just for that.
  19. Hopefully making room for new stuff. About time they marked discontinued stuff as discontinued, as the site was getting pretty bad before due to lack of attention to things like that. I had a soft spot for the CZ and it’s unique target id system and distinct sounds. We’ve been begging for a smaller digital version for over a decade. Maybe miracles do happen?
  20. Main issue for me was SDC poor ergonomics and hardwired coil. Even if they detected gold identically coil to coil, the GPX in the long run will benefit from a better coil selection, like that 17” mono. Still, for a person wanting a simple to operate, easy packing gold vacuum, the 2300 is a great little detector, and close to half the price of the 6000.
  21. “A California woman discovered a 4.38-carat yellow diamond in Arkansas' Crater of Diamonds State Park last month, the state Parks Department said. Noreen Wredberg, of Granite Bay, California, was visiting Hot Springs National Park with her husband, Michael, when she decided to stop by Crater of Diamonds."I first saw the park featured on a TV show several years ago," Wredberg told the Parks Department. "When I realized we weren't too far away, I knew we had to come!"” more at https://www.nbcnews.com/news/us-news/finders-keepers-woman-finds-4-carat-yellow-diamond-national-park-n1280650

  23. If you want a PI to go with your Gold Bug 2 (don’t sell it) the last two used Minelab GPX 4500 on eBay went for $1650 and $1800 respectively. That being the case, I’d patiently shop for a clean used GPX 4500 or GPX 4000. I’d not drop below to the GP or SD models just based on battery differences alone.
