  1. Here is all the latest along with the new instructional video.... Video Review... Specifications and pricing....
  2. Such a beautiful country!
  3. I was looking at some old metal detector catalogs and got a chuckle out of these charts from the 1973 Garrett catalog. People get up in arms about advertising claims these days but get a look at these. To their credit they say "large metal objects" and do not define what that is (dump truck?) but we are talking 1973 BFO detectors here. I need to ditch my new detectors and get one of those old machines! Unfortunately depths were measured in inches then, not feet, on normal targets. The irony is the page is addressing "misleading advertising".

  5. People confuse good settings with good prospecting skills. I find gold so people want to know my settings. Maybe my settings suck, and I am just good at getting my coil over gold nuggets. I actually would tend to argue that more than claiming I am a settings wizard. That is another reason I hate to get into specifics because I am darned if I can say my own settings are even what is best for me. My own opinion is that I am sloppy on settings and succeed mainly though hard work. My technique boils down to crank that baby up and start swinging! JP knows far better than I what makes for a good setting given any circumstance.
  6. There are two types of Gain or Sensitivity settings. One type boosts the actual transmit (TX) power of the detector. The other type boosts or amplifies the receive (RX) signal. The GPZ 7000 Sensitivity setting is the second type. That being the case increasing the sensitivity is not actually making the machine more powerful. You amplify signals from nuggets, but also from ground noise and electrical interference (EMI). Ground setting controls directly affect the signals being generated. One ground setting may cause certain hot rocks to create signals. Another ground setting may eliminate those same hot rocks. Increasing the sensitivity in the first instance will make those hot rock signals and gold nugget signals louder. In the second instance, there is no hot rock signal that can be increased, so increasing the sensitivity control will not make those hot rock signals louder but will boost the response on a gold nugget. The Gold Mode and Ground Type are primary controls as they determine what the detector will or will not detect. The Sensitivity or Gain is a secondary control that amplifies the signals generated. The audio settings, Volume, Threshold Level, Threshold Pitch, Volume Limit, and Audio Smoothing all also act in their various ways to change how you hear the signal after the fact. They are less about changing the generated signal and more about customizing the sounds for your particular hearing. People still play one against the other however, lowering one while increasing another. The main problem when you dig into the details is that THERE ARE NO MAGIC SETTINGS. Different ground types, hot rocks, gold types, and background EMI call for different primary settings. Then our own hearing and brain signal processing call for different secondary control settings. Primary controls like ground type are actually simpler in my opinion. If you have a certain pesky hot rock, and one ground setting really lights it up, and another eliminates it, it is obvious with a bit of experimentation which setting is best. After that however things get messy. What we all want really is a detector that is dead quiet, and then gives a loud, unmistakable beep on a gold nugget, and nothing else. People often strive to reach this ideal level of perfection. The problem is that we all discover that a perfectly quiet detector gives up certain signals, typically the weakest signals. The Threshold control is an easy example. Many people do not like listening to a detector that makes a constant noise. Just turn the threshold down until the machine is like a coin detector - quiet until it goes beep. Most nugget hunters however live and die by the threshold and feel lost without it. It is those faint threshold disturbances that signal a very small or very deep nugget. Games then develop. Lower the Threshold but increase the Sensitivity is an example. It is like putting your foot on the brake while increasing the pressure on the gas pedal, with the great benefit being you can't burn up the brakes. You can still have your silent machine while boosting some signals that may have been lost, but finding the magic combination depends on what signals the primary controls are creating for you to modify in the first place, and that depends exactly where you are detecting. After years of going over this with hundreds of detectors and thousands of people I have come to understand it really is more about our ears and brains. We all have different combinations. We all have different ears, that is fairly easy to understand, and so the threshold setting you find too loud I may find too quiet. It normally just needs to be set as low as possible while still being audible, but that setting may vary due to our hearing. The second part is more to do with our brain. If you hate hearing a noise all day, you may want to set the threshold to just below where it is audible. I may want to set it where it is just barely audible. That may have a bit too much waver in the sound for some people as the ground varies, so they will raise the threshold even more in an attempt to smooth the signal. Which is correct? An engineer can tell you from a technical standpoint, but they would be wrong in my opinion. The trick to prospecting is in the end more mental than almost anything else. For most casual hunters it has to be enjoyable. If it is not, it is a burden to be borne, and we all can only bear a burden for so long. In my opinion the detector has to match your personal style in the way that makes you most comfortable and most likely to persevere and continue detecting. My brain and my style demands constant audio feedback. In theory I want a machine to be perfectly quiet and only make a sound over gold. Forty years of detecting has taught me it does not work that way for me. I like to have the machine deliver constant audio feedback, and so at a minimum I need to have a constant threshold tone. I like to hear faint ground variations as I go. Each detector has its own language, and apparently I have a brain that from long years of detecting has been trained well in these languages. People hear noise, I hear the symphony. It does not matter that much that I have poor hearing - I fix that with the controls and headphones, etc. What matter most to me is getting all the audio into my ears and to my brain, where the real work occurs. EMI makes one noise, ground makes another, rocks make something else, but with time it is the nugget signal that stops me dead in my tracks. Many people when coin detecting just want the machine to beep. Others want a couple tones. Most will balk at more than four tones. I prefer what is called full tones, which on my DFX means 191 different tones. I also do not like rejecting targets, but prefer for them to just have their own tone. It is all music to my ear, and I literally experience all attempts to reduce raw signals as a deadening of information to my brain. Critical information is being withheld and I am not happy. Too put it simply, if my machine is dead quiet, I feel deaf. That is a long explanation of how I detect. I am at one extreme. Another person will be at the other far end, trying hard to make their machine dead quiet unless over a nugget or a coin. In between we have the vast majority of people. seeking their own perfect combination that works for them. None is actually right or wrong - it is what works best for them. I am the renegade on this one because detectorists with more of an engineering bent will insist that no, running too noisy is bad, or running too quiet is bad. From an engineers perspective there is indeed a perfect signal to noise ratio for any given circumstance that is correct, and anything else is incorrect. The problem as I have found it is trying to impose one style of detecting on a person with a different style is hammering a square peg into a round hole. What matters in my opinion is to put very many hours on your detector while learning what every control does by way of experimentation. Then use that knowledge to develop settings that work best for your own situations and detecting style. Reading stuff like this is a very good start but at the end of the day it is like learning to play the guitar by reading about it. To learn and get good with a guitar requires constant practice and a detector is no different. I almost never discuss specific settings, but did so by publishing my Steve's Insanely Hot GPZ 7000 Settings. I kind of regret doing so now. The problem is people latch onto this stuff like it is some kind of gospel. Then you get Lunk's ZED Settings and the debate begins, which is "right" and which is "wrong". The answer is Lunk's settings are right for him, and my settings are right for me, and both of us would change them in a heartbeat if we thought it would be beneficial. More importantly, neither of us would ever advocate just using some settings gleaned off the internet as anything more than a starting point for your own experimentation, to find what works best for you in given locations depending on your own detecting style and preferences. Using some setting off the internet is like buying a car and then getting on the internet and asking which gear setting and throttle setting combination is best. It all depends on the road and the driver. The key thought I want to leave you with is that you just need to be in the ballpark. Detectors are actually pretty forgiving. The most important thing is to work on getting into good locations and practicing good prospecting habits like good coil control and long hours of detecting. Things like that have more impact on the gold you will find then the chase to find the perfect setting. Most nuggets I find to this day I would have found with a wide range of settings and indeed with many different detectors. You have to get the coil over the nugget, first and foremost. Well, way more answer than a simple question asked for, and maybe I just confused the issue. That's what happens when you give me a cup of coffee and put me in front of a keyboard in the morning! Below it says "using the highest stable sensitivity setting will achieve the best performance" (emphasis added). Or go back to Fred's answer above if I have thoroughly confused the issue.
  7. If you try to go to Rob's forum at it's old address at http://forums.nuggethunting.com/ you get a 404 Not Found error. The forum has been moved to a new location at http://forums.robsdetectors.com/ A lot of links just broke - looks like I have some housekeeping to do. Update any saved bookmarks you may have.
  8. I have not even scratched the surface of this website link. All kinds of diverse articles and photos from all over the country. There are many photos of legends in the prospecting world. I tripped over this site years ago, forgot about it, and then found it again yesterday while doing research. Check it out at http://www.billandlindaprospecting.com/
  9. Always nice to hear good news!
  10. People generally want to believe what they want to believe, and as long as you play to that it is relatively easy to con people. I could have been a great con man but my parents raised me right. Being in business I did see many played however. The three most common I saw in Alaska were: 1. Selling worthless ground by association/proximity. All you have to do is stake worthless ground on or near good proven ground, the more famous the better. For example, Bonanza Creek produced tons of gold, but only in the last five miles of its eight mile length. Stake claims on the worthless upper three miles, point at all the history and production downstream - easy sale. Regular folks do not understand how gold deposits work and think if found in one part of a location it is found everywhere else. 2. Just a little more money needed. We have this great ground, and have invested much time and money, and are now almost to the fabulous glory hole. All we need is for you to invest XXXX dollars now and by this fall you will get ten times that back. Somehow most of the money goes to paying my expenses/wages and the glory hole never gets found. Goes well with number 1. above. 3. Believe it or not I have seen the gold from water scam played repeatedly. Glacial silt in water is a popular source of micron gold that can be recovered with the right magic filters. Due to all the glacial silt in Alaska waters and the general Alaska mystique it is a popular destination for people running this scam. The fun part is you are generally wasting your time trying to talk people out of being conned. They will often defend the scammer and even get angry if you push it too hard. The "sunk cost" fallacy from the post above also applies to minds made up. We have invested ourselves into a decision, and will resist being proven wrong. So much so that when presented with contrary evidence, we will decide the evidence is wrong before admitting we are wrong. Attempting to talk someone out of being conned can actually make people more inclined to accept the con. Outright scams blend seamlessly into legal marketing and so caution is always called for. In general, if you are being told what you want to hear, be cautious. A. If you buy this detector device, learn it well, put in the time to research and hunt the right places, and work real hard at it, you may do well. B. If you buy this detector device, it will easily pay for itself. The difference is obvious - beware easy answers.
  11. Geobotany: Plants Associated With Mineral Deposits by Alex Dolbeare Science has shown, over the past few centuries, that there is a direct correlation between certain plants and their geophysical surroundings. ICMJ Article November 2014 (Vol. 84, No. 3)
  12. "NASA recently announced it's latest endeavor: Explore a giant metal asteroid the size of Massachusetts. Made up of mostly nickel and iron, the giant hunk of space metal is about three times further away from the Sun than Earth. Psyche is both the name of an asteroid orbiting between Mars and Jupiter — and the name of a joint NASA/ASU mission to visit that asteroid. The mission was chosen by NASA for one of its series of low-cost missions to solar system targets. The spacecraft will likely launch in 2020 and travel to the asteroid using solar-electric (low-thrust) propulsion. After a six-year cruise, the mission plan calls for 20 months spent in orbit around the asteroid, mapping it and studying its properties."

  13. The article linked to above goes into this subject in great detail. The short answer - this site does not strip GPS info automatically. Never upload any photo with included GPS info intact to any website if you do not want it to be shared. I personally would never trust a website to do it for me - it would be easy to make a website that strips and collects the information instead of stripping and discarding it. Do it yourself first as explained in the link above. Best solution is to use a camera that never collects it in the first place - i.e. a camera without a built in GPS.
  14. This is not exactly new since it was announced last October, but I was wondering if anyone has seen or used these yet? The new Garrett 14" gold pan has a asymmetric design and fixes one of my pet peeves, which was the small bottom area. The Garrett gold panning kits now include these new pans. Here is the new pan next to the old design for comparison...
  15. The Garrett specs out as faster at 17 milliseconds claimed (see spec sheet in first post) versus Pro-Sonic claimed at "less than 50 milliseconds". A GPZ WM12 tested out at 20 ms
  16. Now that is some fine gold! I have always been a nugget chaser myself, but there is something very fascinating about the recovery of very fine gold. It is an art in itself, and the plain fact is you can find tiny gold in a lot more locations than you can find gold nuggets. For many people developing skill at fine gold recovery is a far more productive path to finding gold than chasing gold nuggets.
  17. Back in November there was interest stirred up by reports of a dedicated gold nugget detector being made for XP for sale in Africa - the Depar DPR 600. Details were confirmed later by GaryUK who is tied in with XP and has tested the unit (and stars in the video below). The main news he related was that XP intends to market a version of this dedicated nugget detector outside Africa in 2017. The machine will be a very limited version of the upcoming DEUS V4 update. In fact I think the testing of this unit in Africa was key to the development of the V4 update. The new machine will come stock with the V4 high frequency coil and looks a lot like a DEUS. However, the software will be locked into several versions of the Goldfield program and will not have any functions needed for anything except nugget detecting. Final features may vary in the final US/UK version but here is what Gary says about the DPR 600: The DPR has no pinpoint mode, no expert menu, no multi-tone, no notch, no coin mode, no non-motion menu, no user updates (USB download will only support bug corrections). The current DPR version has no wireless headphone support, no headphone controller, does not support the DEUS coil with lower frequencies (only works with the two HF coils) and only supports 3 high frequencies, not 4. The DPR has a 2 year warranty the Deus has a 5 year warranty. These details were gleaned from Garys post on his forum but it may not be visible to people who are not forum members as I am currently. Andy Sabisch has also confirmed the existence of this new model planned for 2017 at Findmall. The bottom line is this machine will resemble a DEUS and will have a very limited feature set focused on nugget detecting, but at a lower price. No idea on price or availability for as we all know the V4 update is running late. There is nothing here per se for current DEUS owners because the V4 update will give a DEUS owners all the features of the new machine plus tons more. But for somebody looking for a very light weight nugget detector this new machine may very well offer an upgrade over existing single frequency models. I have always thought the DEUS was overpriced for people who just want to nugget detect, although it does have the capability. A dedicated nugget detector at a price more in line with what you expect of other VLF nugget detectors could be a very good move for XP in my opinion.

  21. That is too many people lost close together - I am sorry to hear it. That is the first gold I have seen posted found with the Racer 2. Have you seen any way in which it is preferable to the Gold Racer? I have a theory it might handle some ground more smoothly than the Gold Racer due to a lower operating frequency while of course also giving up a bit of hots on tiny gold. Notching might be handy for certain hot rocks or trash.
  22. The July 2016 issue of the ICMJ magazine contains an article I wrote reprising my 2011 trip to Australia to hunt gold with Chris Ralph and Jonathan Porter. Subscribers can view the article online at http://www.icmj.com/article-notloggedin.php?id=3479 There was of course a lot more to say about the trip than was contained in the article, and in particular I have a lot more photos to share. I kept a diary while on the trip, and this thread is intended to provide a much more detailed look at the trip. I will keep posting on this thread in a serial fashion similar to what I did with my Alaska gold adventures with my diary providing daily details. It all started in 2010 at the old AMDS Adventure Forum when I made this post on a thread: "Hi murph, You know, for many years it was my dream to go hunt nuggets in Australia. I got Doug Stone's books and read everything else I could and dreamed of those monster nuggets. But as years went by I read between the lines and figured it is a tough go to find the big nuggets in Australia these days. The fact is you only read about people making finds, but plenty of visitors to Oz find no gold. There is always the home team advantage. It is not so much what you know as who you know, and I'll always have a tremendous advantage in Alaska just because I've lived here all my life. Though I do have a few contacts in Oz that might give me a leg up on the average visitor. Still, it may be that my chance to visit Australia is coming as my circumstances have taken a turn for the better. So maybe in a couple years?" That in turn generated a response from famed Australian gold prospector Jonathan Porter: "Steve I will tell you this, if you ever decide to visit Australia it would be my pleasure to show you around. There is still plenty of potential here in Australia, the auriferous areas are just too extensive and in some cases very inaccessible so there just has to be good nugget patches waiting for someone gutsy enough to come along and swing their coil over that first lump. I intend to get into some tiger country this year and could do with a good partner who doesn't need a gold fix every day, interested? - JP" It turns out that JP and ICMJ Associate editor Chris Ralph had been discussing the possibility of a joint prospecting trip in Australia. I had met Chris previously when I had invited him up to visit my Moore Creek pay-to-mine operation several years earlier. A few messages were passed back and forth offline, and I was fortunate enough to be invited to join in on the adventure. Trying to pick the best time as regards weather was a big priority, and it was decided that the fall of 2011 would be the best bet for putting a trip together. Australia is in the southern hemisphere, and so the seasons are the reverse of what we experience in the United States. Our fall is their spring and we timed it to hit cooler temperatures that would be warming while we were there. Jonathan's advice was critical here. We wanted several weeks to give it a good go and decided the entire month of September 2011 would work well. That gave us plenty of time to plan and make arrangements so we put it on our calendars.

  23. Still looking for my first one. Great finds and better yet one to share!
  24. If I Google "alarm metal non-ferrous gold silver gpx 5000" I unfortunately get many returns for fake GPX 5000 detectors. No GPX 5000 can tell gold from silver and they do not have an "Alarm Metal" function. Google search result Unfortunately it is almost 100% certain that you have counterfeit machines.
