  1. I have to use the GPX coil sticker on smaller targets as the edge of the coil is not able to hear small faint signals. On larger targets the already mentioned above works pretty good. I would also add I use the Pro-find 35 pinpointer on larger targets when I do not bring the Gold Bug 2 along. This pinpointer has a few learning challenges, but is very sensitive on 3 grain nuggets and a lot more so on larger targets saving me a lot of time and energy in locating targets and not having to lift up a 4.6 pound detector multiple times to locate a target. I felt I paid for my Pro-find 35 the first two days using it. Ron’s Detector’s
  2. Gerry, Add 40% deeper to the GPX 6000 and there would only be one detector ever needed for placer gold, call it the gold vacuum. This detector is way better than I ever imagined the GoldBug 3 could of possibly been except for discrimination.👑 Nice job with the finds! Ron’s Detector ‘s
  3. Thank You all for your wise input. I really like the looks of the lightweight rucksack straps with the simplicity of the Zed bungee system on it. The addition of the guide arm also sounds like a winner for the 17” coil. 👍
  4. Felix arami, thanks for your response. yes, I would agree that Doc really came up with the best bungee systems that I’ve encountered so far. The longer lower shaft will also help taller people by allowing the bungee to be more forward on the shaft, in return helping to keep it from hitting the control pad so much. My post goal here is to figure out how to get more hours in a day detecting, lately been feeling the shoulder and back feeling sore after two days back to back detecting.
  5. Has anyone found a good balanced bungee setup that works well with the GPX 6000?
  6. I’m usually 30 or more miles away from cell phone service on my more remote adventures. A spare key is a necessity on the vehicle and a battery shutoff switch to keep door lights and accessories from draining the battery on multi day trips. Ron’s Detector’s
  7. Oneguy, I have had very faint small or deep target signals do this with the GPX 6000, mostly in heavily mineralized ground. I then usually scrape the ground surface with my foot and if the target gets louder or returns then I know it is a dig target, sometimes hot rocks will have the same sound volume as I dig down a few inches which reveals it’s probably a hot rock. Nice gold by the way👌 Ron’s detector’s
  8. If you’re ok with digging all targets with the GPX 6000 and feel confident that the corrosive salt water will not get into the control box then it will go deeper than the CTX 3030.
  9. The GPX 6000 does not have iron ID and it just has a heavy rain resistant control box, otherwise it’s a great detector for creeks since the coil is submersible, lighter in weight, and it has less cords to deal with. Also, this detector reaches a new level on smaller sub gram placer gold, definitely worth the extra money over the GPX 5000. Ron,s detectors
  10. I would also try a factory reset, I was not able to hear my tester target one day after using the same settings for a few weeks. Did a factory reset and put the same settings back in and everything was working normal again.
  11. Jeff, I would also really like a DD 6x10. I had mentioned a few reasons in the above post, but your situation also adds more rationale to having a smaller DD. Hopefully these new coils come out as soon as possible and match what the consumer needs reflect in our post.
  12. Steve, Thank You for the clarification on the warble and speaker feedback possibilities. I can now say my GPX6000 is running fine and cannot be compared to the GPX 5000 in regards to its rock solid threshold. I have also been able to hear through the excessive warble the majority of the time and also use the factory reset or noise cancel when it overwhelms me with excessive warble. The sensitivity is like no other detector that I have ever ran on the smaller placer gold sites. I’m also very pleased with its ability to use all the timings in conjunction simultaneously. I have found when using the external speaker while working in very hot ground (serpentinite) and using the lower sensitivity levels and lower volume levels it seems to lowers the amount of excessive warble. In some but not all situations the headphones do appear to help lower this excessive warble also. Hopefully these issues in the future can be fixed in the software or maybe a speaker replacement is necessary. Reminds me of when the the first GP Extreme models came out there was a similar issue in which was fully resolved by the time the GP 3000 was released and Minelab added the low-noise circuitry resulting in a smoother threshold. Thank You again!
  13. Steve, I was wondering what is considered a normal amount of warble for the GPX6000’s threshold noise as I do not have another detector to compare mine to. Could you please clarify how often you have to use the noise cancel to stabilize the detector and if using it always calms the unstable or noisy threshold down. I am trying to find any solution to settling down the unstable threshold on mine as it seems to run a little bit unstable in the higher sensitivity levels especially when not using the headphones.
  14. If you do not want to drive to far from the goldfields, there is a small chance one might find a diamond while gold mining. Hayfork Creek in Trinity County and the Cherokee hydraulic mine in Butte County have both produced some larger diamonds found while gold mining. That would be a double dandy day to find both in the same spot. Even better, platinum nuggets can be found in the serpentine belts in California which includes parts of Trinity County.
  15. I would recommend a used Minelab GP 3000/3500 for a PI and a Equinox 800 with 6” coil for a VLF. If this is over $2,000 then maybe a lesser priced single frequency VLF such as a Garrett 24k. These two detectors will cover most gold types you’ll most likely encounter and be able to handle the more difficult types of ground mineralization. If your goal is placer gold in heavily mineralized ground then just get a GPX 5000.
  16. I would really like to have a headphone and a wm12 with the jbl external speaker. I would have the ability to hear the threshold well enough with the jbl speaker when working alone and have headphones when working around others. The headphone I’d prefer could allow only one side to work or both sides so I could hear the wildlife 🙁.
  17. Chris Ralph’s book Fist Full of Gold is a pretty good training guide. Next DP forum past and current post research is quite comprehensive in learning the in and out of prospecting with a variety of detectors. Once you have read all this information you should be ready to get some detecting time in with very little problems. After a couple hundred hours of detecting you should be quite efficient with your detector. If you’re not finding much, then It’s all about better research on where things you would like to find were found before. 😎
  18. Trev, I had a question, can a 6x10 DD coil be equally as sensitive as the 11” stock round. Please see the above quote for a better explanation of what would help in handling the ground effects in my area. Thanks for any information. Ron
  19. IMHO The Mono 9x14 and 6x10 would work well in most of my areas. Also a 6x10 DD would really fit into a need i see here in the localized heavy mineralized ground. Let me explain this better, we have a mix of soil types were I detect, some serpentine and some granite/rhyolites. The Mono coils is preferred and fit most needs here in the granite/rhyolite areas, but the Mono coils do tend to false on the serpentine bedrock here. Maybe the 6x10 DD would be a good match for the GPX6000 as it is already very sensitive with the 11” and the DD could maybe balance this sensitivity out with the 6x10 DD, maybe even match the 11” mono sensitivity for matching gold nuggets sizes and also being able to handle the hottest ground located here. We already have a 14” DD and it looses a little bit of sensitivity in comparison to the 11” Mono, so I probably would not purchase a elliptical DD option for that size if I could just use a 6x10 DD coil instead with better sensitivity. I am also curious on how sensitivity on a 6x10 Mono would handle the ground effects, hopefully it can still handle the ground effects and not be to overly sensitive. Don’t get me wrong as I would love to have a more sensitive coil as long as I do not get an overwhelming amount of annoying ground noise. Coiltek, Can you please let me know your thoughts on these assumptions since you are the experts here. Also can the weights of the coils be lowered at all using carbon fiber or other materials?
  20. Just some thoughts I've noticed, I have had noticed some EMI when next to multiple cell phones or when using the external speaker, but when I leave my cell phone in the vehicle and use the headphones everything seems a lot better. I primarily use the 11" Mono and have worked within 30 feet of power lines with very little EMI, in fact less EMI than my older PI machine has had in the same area. I do seem to need to do a few noise cancels, this occurs mostly after I'm lifting the coil high off the ground and letting it back onto the ground frequently. Some tips I have followed are JP's advice on letting the detector warm up and remember that if things do not seem right, then it is best to do a factory preset. In regards to the coil twist, I would definitely like tighter shaft locks, but actually prefer not to have a fixed position coil lock. The reason for this is to have the ability to twist the coil at an angle parallel to the ground when working side hills within hydraulic pits, the holding the detector straight up and down and having the coil at different angles of the slope causes a lot less fatigue on my arms (shoulders) and is easier to swing the coil close to the ground. I am also prone to tripping a lot and pushing the coil into the ground pretty hard and have thought multiple times that I would of broke the coil tabs off if it had not been for the twisting of the shaft which absorbs most of the shock. It could beneficial if just the upper shaft lock did lock though, as i do like the Vanquish series square quick locks.
  21. I like running the GPX6000 like a hotrod and trying to hear through the chatter, so I have been using Auto + with success patch hunting in a area that has very few hot rocks, just hit the difficult button when I encounter a hot rock and its usually gone, but will still get a great response on the small gold targets when switching to difficult, if in doubt I just switch from normal to difficult mode to see if it's a metal target or ground effect. This matches up with what JP mentions on the small gold timings in the difficult settings. I also tried comparing the Auto to the Auto + but could only notice a very small difference. Would the Auto be comparable to one of the Manual setting, if so which number would closely match it? Another thing I have been trying to do is determine the high/low tone responses on different objects in Normal vs. Difficult settings to help in trashy sites. Steve Herschbach has mentioned this in a topic linked below and got me started doing some testing. My goal is to use these setting to separate out my most common targets, square nails. Please read the article below to better understand this concept.
  22. Seems like everything Minelab has been working on is improving, who knows where they will go next, maybe a GPX 6000 with a flip switch turning it into a Nox 800.
  23. Tony, IMHO Depending on your ground, most 20 kHz and lower frequencies are better at handling the more mineralized ground conditions. That’s why I use the Equinox 800 in heavily mineralized ground as it gives you a single 20 kHz frequency for hot ground or you have the multi-frequency option for less reactive ground when looking for smaller gold. It also has some really good discrimination abilities for trash sites. If any 20 kHz or lower detector doesn’t work in your ground then I would recommend a PI machine at that point.
