  1. What region are you in? The TDI as a ground balancing pulse induction detector shines in mineralized beach conditions. Volcanic islands for instance. Not so much on coral derived white sand beaches.
  2. As a separate item? I don’t know. No mention of it on White’s website. Obviously they are making them since they come with the GMX so maybe all it takes is a phone call to the factory. Which I have not done.
  3. Ok, it’s February.... where are the coils? 🤷🏼‍♂️
  4. The two detectors are neck and neck for gold finding capability. The 48 kHz White’s 24K at $729 is lower price out of pocket, but the 45 kHz Gold Monster at $849 comes with two coils and a rechargeable battery pack. If tuned as hot as possible but for stable operation the machines have almost identical performance. It is possible to overdrive the Gold Monster sensitivity to get a slight edge over the 24K, but it comes at the price of the coils becoming unstable and knock sensitive. I like both machines a lot and when I weeded out my collection they both stayed longer than most as I had a hard time deciding which I liked best. After a year of using both I finally sold the Gold Monster and kept the 24K. Why? Ergonomics had a lot to do with it. The 24K comes with an adjustable length rod, the GM a three piece screw together rod. Yeah, you can replace it, but why should you have to? The 24K “S” rod is counterbalanced by the battery pack under the arm, and is more comfortable than the nose heavy GM. The round handle on the 24K fits my hand better than the squared off GM handle. Finally, the 24K stays put when set on the ground and does not roll over like the top heavy GM. Each of these is a small thing in practice but all together add up to a solid ergonomic win for the 24K. The biggie for me however is enhanced options and control. I won’t make a list, suffice it to say the GM was designed for simplicity and as few controls as possible. The 24K on the other hand has a full suite of tuning options including full target id capability, which the GM lacks. I’m a control freak and more than anything else that’s what tipped it for me. The 24K is more versatile. Finally, coils. The GM you have the 5” round DD and 6” x 10” DD. The 24K has the 6.5” round concentric, 6” x 10” DD, 4” x 6” DD, and very soon 8” x 14” DD. To sum up I look at the machines as being a push when it comes to gold finding capability. Give me either and I will do fine and be happy. I recommend the GM for somebody who is control adverse and won’t read manuals. It’s as near automatic as you can get, just don’t overdrive the sensitivity. The 24K offers more versatility for those who thrive on that sort of thing, and along with the ergonomics out of box and extra coil options now I believe White’s has produced an excellent offering in the 24K. In my case at least it’s the one that stayed when the others went away. White’s Goldmaster 24K Data & Reviews
  5. Welcome to the forum! Check and see if you have any local metal detecting clubs... always a great place to start.
  6. I’m not too worried about the name. It just seems like this would be the next detector on the list at Nokta/Makro, and a reasonable target date might be Detectival in September for an announcement. Availability next year. Just guessing.
  7. The ferrous/non-ferrous break point in the 24K is set at 50 and gold in highly mineralized ground may read lower than 50.
  8. How Deep Can I Detect Stuff? Most items you will dig will be less than a foot deep and only huge items more than two feet deep. People in this hobby spend another thousand dollars to get another inch or two of depth. $300 can get you a top notch detector these days. Good locations and hours are the key to success.
  9. Take it to a local rock club or school geology department. Of post a really sharp photo.
  10. Did anything ever come of this contest? It’s been over a year since the last post.
  11. Too out of focus but at a guess I'd say arsenopyrite, a sulphide, and highly conductive. Second guess graphite. If it will easily mark up paper go with graphite. Whether some magnetic minerals sound off or not depends on the ground balance setting. Others that are conductive, like arsenopyrite, will pretty much beep no matter what. I have found many pounds of arsenopyrite while metal detecting so toss the sulphides are undetectable theory. It just depends on the sulphide.
  12. There is an edit button under existing posts Jim. I fixed it for you but you can edit your own prior posts for up to 90 days. Your welcome Larry. The 24K is a great nugget detector and with some knowledge can be used for other tasks as well.
  13. Nice looking backpack. Longest part is 24" so a GPX upper rod or CTX lower rod would not fit but that's not the pack's fault. Really made more for smaller VLF detectors. If I did not already have a pile of packs I might be tempted but at US$149.00 I'll pass. Not my language but the video is very good....
  14. With 2019 in the rear view mirror what will 2020 bring? Multi Frequency? Pulse Induction? One thing is for sure, this company is going places fast!
  15. Your numbers are posted so as to add a little confusion, so let's puts them in numeric order: Normal nail 0 nickel 28 tab 35 ring 40 penny 56 dime 70 quarter 82 GK24k nail 39 nickel 89 tab 91 ring 94 penny 95 dime 97 quarter 98 Discrimination systems do not tell you what metal you are detecting. Any metal can read almost anywhere on the scale depending on size. Also, the number range chosen is arbitrarily determined by the manufacturer. I assume you are using the standard White's -95 to 0 to +95 scale. There are many others, see the link below. Where target id numbers end up is determined by frequency, and the result can be raw or normalized. Low frequencies shift numbers lower. High frequencies shift numbers higher. Normalization picks one frequency, and makes all results fit mathematically to make memorization of results easier. For historical reasons White’s normalizes to 6.59 kHz. What matters is not the numbers, but the order of the numbers. The 24K is a very high frequency detector at 48 kHz and it is using raw target id numbers, so they are all compressed to the high end of the scale. As you can see the order remains the same. In other words, what you are seeing is what I expect with this detector. Keep in mind this is not a coin detector, but a gold nugget detector, so the emphasis was not in matching coin detector target id numbers but in getting good ferrous and non-ferrous separation. Leaving the numbers as high frequency raw results increases the target spread on the low end and enhances the ability to separate ferrous and non-ferrous. Note that on the normalized White’s scale the range from ferrous to nickel is 28 points. On the 24K it is nearly double at about 50 points. The low end has far more spread between low conductive target id numbers but the result is most coins lump together on the high end. See the V3i info at the link below for a good explanation of frequency effects and target id normalization. Lots of reading and links here to fill in the gaps.... What Is Metal Detector Discrimination an How Does it Work?
  16. All I’m seeing is this “I have very strong reservations if this unit will ever make it to market.” It does not matter what it does if you can’t get one.

  18. I don’t. They are made to be used, not babied. I’ve used hundreds of coils over the last 45 years and had few problems. I don’t recommend using them for a walking stick or leaning on them, but swinging and scraping the ground is what coils do day in and day out. Seriously, you are just having a little bad luck.
  19. If you are pushing down hard enough to deform the coil and shift the windings that’s could do it.
  20. If you have the sensitivity at a fine edge pushing down could put the coil in closer contact with the ground and cause an overload. Sounds like you are a little gun shy at this point.
  21. Superb post Chase! It will be the first one added to the Essentials page in quite some time.
