Aureous

so is this mod a variable sweep speed or just set to accept a wider range of speeds? my brother uses his tdi-sl as his primary detector due to the massive mineralization he has to cope with in his district. he will be very interested.....

I can totally agree with the user reports, here in Australia, I can state that there is no VLF high frequency machine more capable than the 24K. Ive owned and used them all, the Gold Bug 2 was my favorite until now....over 6,000 bits of gold with it. Im up to 500 with the 24k but injury and work have gotten in the way of detector time. A small DD coil is all thats urgently needed in my 24K arsenal. I can think of dozens of small gold locations that will benefit from this combo.....cant wait!

After having looked at this whole thread, Ive seen 2 glaring gaps in the posts, and from my own perspective they need to be said. I watched a good coil technician build a 10" GPZ coil way back in 2017. He deconstructed a 14" ML coil, worked out the parameters, made a patch block (not a lead, coz he was only doing bench testing at the time) and built 4 prototypes of varying merit until he built one that worked really well and was field tested extensively. THIS TOOK HIM 2 WEEKS......one man. On a technical standpoint, there is zero excuse for ML NOT to be able to build numerous designs OR give the task to either of the major coil players in Oz OR at least another 4 guys who are known to be top notch coil technicians. Indeed, both of the big players are logically rumored to have made several GPZ coil prototypes in the past couple years for just such a time. Again, NO EXCUSES. OK, 1st statement made. 2nd statement, and another really obvious one, a large coil selection SELLS DETECTORS. The more variable and adaptable a detector is, the more likely it is to be sold. At this stage in the GPZ's life-span anyone with a logical view of the detector industry should glaringly see that leftover warehouse/floor stock of GPZ's would sell better with more coil selection. With the GPZ about to be replaced, this would be an obvious time for ML to 'allow' coils to be made. I wish I could afford to buy a GPZ just so I could join in now.....

Still no word nor listing on the whites website for the new 24K mini DD coil.... anyone heard anything????

There IS a program out there to read the resultant code, Ive seen it done. The frequency variation is easy to discern though, part of the chip appears to be a simple frequency matcher. I would have to chat with the tech who showed me to get more info. He made 3 bench coils for the zed back in 2017. Just for fun I think...

Big tip for anyone considering making GPZ coils: once the patch cable is made, a sensor probe can be attached and the chip info is easily seen being transmitted from coil to the motherboard....those with the right equipment can determine what kind of data needs to be flashed onto the coil chip....I expect thats what our Russian friend has already done if he's making chipped patch cables for general sale...

The GB2 coil has a square windings connector. The 'fireworks' are 2x ground-shield sprays of light gauge wire to attempt deadening of ground noise. Always a difficult thing to attempt when utilizing concentric designs in the goldfield soil conditions. the rest of the loose wire is excess tuning wire to reach the correct induction and frequency match. Ive seen much cleaner versions of GB2 coils than that...musta been a bad day when that one was made lol

Re coil patents, the DDO design is an old one, both Fisher and D-Tex had DDO designs for certain back in the 70's and 80's. And, the Russian dude isnt the only one who has made GPZ coils. At least 3 other technicians/companies have made prototypes within the last 2-3 years....

For use on the 7000, the X coils are all DDO (or now re-named DOD)....3 sets of windings, One large transmit, two smaller receive. X coils also make a typical spiral wound mono for use with all GP and GPX detectors.

The family in question was using nuthin but Fisher 440's. 1st trip got them about 20oz....2nd was maybe 200oz. Nuthin smaller than 2-3 grammers though.....them was the days....

I had a chance to go with a semi successful gold prospecting family on a trip to Western Australia back in 1981 and had to decline because of school commitments. They went anyway, hit a huge patch and bought a car dealership with the proceeds (still running today) and made million$. If I went back, I'd drop out of school and stay in WA until I'd filled a bucket of gold lol

Editors Note: Split from Vanquish Thread Very true Reg, very few 'young'uns' are having a go....but a certain TV show is helping to a small degree I suspect. But from what Ive seen, the current 'instant gratification' generation doesnt have the patience or fortitude to spend time in the bush for more than half an hour...

Quite right, knowing what I do about ML in the past, their R&D dept is normally 4+ years ahead in concept/design/prototype phases at any given time. The reason Minelab have 'wrung the necks' of all their competitors (except, amazingly the Turks) is their massive commitment to R&D. Believe me, they can toss out a new detector whenever needed to fill a void, shrinking niche sales or to squash potential competition. Because all the boards, tooling and CAD is already on file, the lead time is fairly short. The SDC 2300 was released in a hurry and wasnt on the yearly horizon due to perceived competition from Garretts ATX. So, thats one particular case in point. Because of the news 'leaked' to the dealers, this might be on the cards again. If nothing tangible was revealed, this extended thread wouldn't exist past the Vanquish release info. But the release date for the new gold prospecting detectors will as always, entirely depend on sales volume of current machines and perceived or actual competition. But....the 4 year cycle is well and truly up for both the 2300 and the 7000. That much IS fact. We wait....and see....

Nukem, yes the 'vanquish being the GPZ replacement' horse bolted almost a week ago... no discussion there. But the 3 new types of detector due out in FY19/20 suggestions are still open to interpretation until official word is released.

Shareholder/Investor advice is updated quarterly with most companies, perhaps we can expect a surprise in October.... but who knows? Its not the first time that actual ML product info was 'leaked' well before its actual release....all we can say for sure is that there are more than a few models already overdue for replacement

So sad...they just never invested in new tech or new ideas. A company stagnated & fallen. RIP Tesoro. Jack Gifford will be rolling in his grave ? I was a huge Tesoro fanatic back in the 80's and 90's.... Mayan, Diablo, Diablo 2, Toltec 100, Bandido, Lobo, Dingo, Golden Sabre...many a dollar was spent by me and my Brother on Tesoro gear. Found my oldest coin ever with a Golden sabre, found over 100oz of gold with the Mayan and the Diablos, Lobo and Dingo. Found almost 1 tonne of meteorites with the Diablos..... If they'd have competed with the big 4 in terms of tech and innovation over the past decade, I'd still have their detectors in my arsenal.

See my previous post re the timeline and overdue replacement practices of ML. As far as 'rumors' go, if the info didn't come from the dealers that were informed about it at the recent dealer conference, it would indeed just be rumors. FY 19/20 is still a 12 month wait time and who knows exactly when either of the PI replacements will 'pop up'??? Maybe a betting man would expect just before Xmas???? ?

All us Aussies keep a very close eye on Minelab and its practices.... 4 years is about right for all of their High end gold machines to be replaced. The GPX4500 is the biggest selling pulse machine for ML (and maybe the biggest selling ever) but still, the 4 years were up and the GPX5000 was released.....despite the 4500 still selling well. Both the 2300 and 7000 are well overdue..... FY 2019/20 is still 12 months of potential wait-time....but the new 'Uber gold detector' wouldnt have been mentioned to Aussie dealers if it wasnt going to happen.

Throws the Garrett away in disgust lol Hilarious and cheeky....

Yes, quite right Rick. The years are a blur when you're old

Nukem, talk to a dealer who there at the conference. Tell them that you heard about the 3 different machines including a new Pulse gold unit due out this FY. If you know them well enough, you'll tell right away if its true. I've heard it from 2 dealers and confirmed it with a 3rd. The SDC is almost 5 years old and the GPZ is 4 years old in November. They are BOTH due for a replacement this FY. ML upgrades their units in each market niche every 4 years on average.

Remember guys, the info was that there are 3 detector types due out from ML this financial year. The Vanquish series is just one of them. The GPZ is due for replacement in November (4 years is up). The SDC 2300 is overdue by almost a year. Something to think about ?

NHNZ, I havent used the ground scan much but I can see that it functions as advertised. Yes I love the threshold on the 24K, it never wavers in most ground conditions, only in hot ground or salty ground. The 6x4DD still isnt being advertised yet?

Yes, the QED is more of a task to get running well if you're used to Minelab PI's....if its all green pasture to you, with zero PI experience, the QED will suffice nicely. Get some in field training with Reg or Stinky Pete and you'll find its a great unit at a great price. But get some flat-wound mono coils to run on it, the 9" Elite and 14x9 Evo worked great on mine.

Interestingly, the AU$12,995 price tag would indicate a gold prospecting unit in the same vein as the GP7000, same $$ number that I was told a few days ago. No coin/relic machine would sell for that $$
