Yep, we have become a bunch of softies, they'd have a good chuckle at the things we complain about. Oh you have to carry 3kg, you poor little thing. 😅

Sounds like you've got a bad coil strick as mine are not bump sensitive in any way, neither was JW's coil right up until it died, fortunately the aftermarket ones will be out soon and should be better build quality, they're hand made too so at least it means they're tested before leaving the factory, Be sure to add yours to the poll when you know if its a lemon or not 🙂 I'm starting with the NF 12x7" and if I like it I'll get the 8.5x6" too. I didn't want to start with the smallest as I'm satisfied with the sizes of small gold the 11" finds, I just want some more depth on it and if a smaller coil provides more depth on small gold I'll be happy, it should do, it's how it normally works for me. In the World in which we live now you don't need a King and a Queen, two Kings is very acceptable these days so who knows, maybe once I get some more coils the 6000 might move up the ranks for me too. Novic, I am just not the kinda guy to make it into the back country like that on foot, I would need to hike for weeks to get in there, and climb over many mountains on my way, these are not the little humps in the ground you Aussies call mountains 🙂 I really am amazed at the work the old timers have done here, and the distances and ground they covered to do so, it's truly amazing what they did. I guess they just kept walking and climbing to get to new places and followed the gold, I couldn't survive if I was doing what they did.

someone has had a similar question in the past https://www.detectorprospector.com/forums/topic/15389-whites-beachhunter-id-have-something-remarkable/

Yes, it's hot and dry in summer so the snow melts off those smaller mountains in the photos there, the bigger ones further in keep it. I bought the 6000 for the purpose of backpacking, the GPZ isn't ideal for that as it just doesn't shrink down enough and its hanging out the top of my backpack, the 6000 is ideal that it shrinks down small and quickly. To fit the GPZ in I really need to pull it all apart. I don't see either detector as being "King", they each have their benefits although I do prefer the 7000, perhaps the GPZ 8000 when and if it comes out will be king as it might combine the best of both detectors and offer a coil selection like the GPZ has available from the aftermarket. As people say already the 7000 with the aftermarket coils already fells like an 8000, only an 8000 very few people have.

The marketing for the 6000 makes dealer training seem not necessary, easy experts so I can see why some buyers may not feel it necessary to take classes. I think it's a shame big box stores are taking sales away from the personal service of a dealer. In NZ there is still lots of gold to be found, a coil is very small compared to the gold bearing ground as so few using them to begin with, the problem is you can't get to it, it's too inaccessible, it's not like Australia where people park up there with a caravan and start detecting. The best ground needs a helicopter to get to it, the old timers got there and worked it well but much is untouched. My dealer mate takes beginners on heli gold tours and the last one stumbled on a 16 gram nugget with his 6000, small for Australia I see people all the time show finds bigger but a good size for here. It keeps the hope alive ill have my turn. I'm looking down on the gold bearing valleys right now wishing I could get in there. This is why for me the 6000 has potential, a light portable detector that fits in a backpack easily is beneficial, getting it into the places is the hard bit. A lot of old timer mining out there, just no easy way to get there. I have found some gold down there, just wish I could get further in.

Sorry just sitting in the cafe at the ski field the past couple of hours trying to entertain myself. Got up early for first tracks and they've had a power outage, should have went to a different ski field but didn't think it'd be out this long. The USA customers are lucky to have dealers like you and Rob that share a passion and are not just about raiding their wallets. I'd like to go on one of your classes Gerry, it'd be interesting.

Prince Charles calls his Ross Royce dealer about an unusual problem he is having with his car. Dealer: Hello, thank you for calling Rolls Royce Westminster, How may I be of service Charles hmmmmm I'm not very happy with my Roll Royce Dealer: You must always be happy with your Rolls Royce, they're the best cars on the planet Charles: yes very good cars, very good, but my car has a problem Dealer: Rolls Royce don't have problems, you must be doing something wrong. Charles: Well if I turn on my stereo to listen to some music while going to visit the Queen my car becomes very erratic Dealer: yes Charles: This is my problem I can't use my stereo system Dealer: yes Charles: Can you fix this Dealer: No, this is not a problem Charles: Well, I want to listen to my entertainment system while being driven around, I have good songs to listen to like Crazy Frog Axel F Dealer: You can listen to your music Charles: yes but the driver tells me if I do the car becomes erratic and he gets very annoyed Dealer: yes, well you could always use headphones Charles: I don't like headphones and the photographers taking photos of my every move would wonder why I am wearing headphones in the Rolls and put photos in the magazines Dealer: Well, Rolls Royce are the best cars so if you want to continue to drive our cars and listen to your music you must wear headphones Charles: I was talking to the young boy that comes to cleans up the deification from my mother the Queens Corgis and his Rover from 1982 has speakers that work well, he can listen to whatever he wants to and his vehicle operation remains unchanged while doing so Dealer: yes, so is there anything we can help you with, Rolls Royce are the best cars on the planet fit for a Royal such as yourself. Charles: Why did you install speakers if I should not use them? Dealer: Customers like speakers, anyway Rolls Royce do not have problems, so how can I help you today? Charles: No there is nothing you can help me with, thank you, everything is great with my car and it's fit for a King. I will be King one day Dealer: yes, yes you will, good bye now and please tell everybody how great your Rolls Royce is. Charles: Thank you, bye for now.

Gerry could sell steak to a vegan. 🙂

Well they clearly point out the ZVT is always going to be better than PI for depth on bigger deeper gold and we're seeing that with the focus on the 6000 being away from that gold. It looks to me like they do plan on doing a GPZ 8000 and not stopping ZVT in favour of PI which I believe would be a massive mistake. Just slapping a small coil on ZVT has proven it holds its own or I believe beat a PI machine designed for finding small gold, the GPZ didn't need anything else done, just a coil change to accomplish this. It shows there is a lot going on under the hood. So if they were to make a GPZ 8000 and tweak it a bit more and release it with a range of coil sizes I think I'd be buying it, at the moment I don't think I am interested in buying anymore Minelab Gold Detectors, this mouse has jumped off the wheel. They jumps in technology are no longer enough for me to justify the price for my needs and I'm super happy with my current gear. If the PI's like the 6000 are beating ZVT on specimen gold perhaps that's something they need to work on and improve, they clearly improved on it over the 5000 to the 6000 as it appears the 5000 was pretty poor on it. The SDC was better on it so they knew what they had to do with PI I guess. My question is with ZVT being a bit of a hybrid almost VLF like detector is that the technology that could finally bring good discrimination and even the holy grail Target ID's to a detector like that? I hope I see that sort of thing in my lifetime. A coin capable Target ID detector with the depth of the GPZ would be outstanding and a real game changer the world over. People who don't think there are deep coins just haven't found any in the ground with the current technology, they're often there hiding away especially in places with softer soil or an ancient history. VLF's were trying to make us buy a detector for tasks like separate gold detectors and coin and jewellery detectors, over time this was no longer viable and they merged into one. Now we have multi purpose detectors that are as good or better than single purpose detectors, I would be as happy as can be if this also happened with high end gold detectors also becoming coil, jewellery, relic detectors for all environments. Minelab has seen in their bottom line coin and jewellery is where it's at for making money lately, so who knows what the future holds. Everything I've read leads me to believe ZVT isn't classified as PI, but it's so hard to understand what they're saying for my brain, it makes it hurt.

Nokta copied Minelabs detector, XP copied Minelabs quality 😛 Just joking, sort of, it seems almost every manufacturers quality has gone down hill lately. No brand seems immune, even those that were touted as the greatest build quality have resulted in many failures with their latest release. I don't know if it's related to their factories and Covid or what it is, hopefully things improve in the future and this isn't a sign of things to come. I was kicking back the other day and thinking about it and the only brand I own a fair few detectors from that I've never had a problem with are Garrett, I have four of their detectors two of which are near entry level and three of their pinpointers and never once had a fault yet other brands have let me down, especially Minelab. That's not saying Garrett's don't break down as I've seen a few Apex bite the dust, but at least for me they haven't. My only XP is a pinpointer and I love it. Sorry to hear of your problems Erik, I certainly know how frustrating problems with a new expensive detector can be and they really put you off using it, and you were just starting to make friends with that XP, you were starting to bond with it and now here we are.

Are you sure, it's so confusing in their documents it's hard to know, they're very much trying to differentiate it here They say it's continuous wave where as PI is not. Another disadvantage of PI is its capability at detecting very large nuggets compared to CW metal detectors, such as ZVT. CW means Continuous Wave and includes all technologies that do not have zero transmit periods (almost all technologies other than PI). Zero Voltage Transmission (ZVT) – ZVT has the same major advantage as PI for ground balancing in not detecting the major soil component X, but has the same advantage of CW metal detector technologies compared to PI for detecting very large nuggets because ZVT is CW (unlike PI that is not CW), and also the same advantage as PI for being relatively insensitive to saline soils compared to VLF. What is the ZVT transmitted field, and how does it differ to PI? Both ZVT and PI measure a signal (receive signal) immediately after a very rapid change in magnetic field. During the receiving (measuring) period, PI does not transmit a magnetic field at all, whereas ZVT transmits an exceptionally constant magnetic field (until the next very rapid change in magnetic field occurs). The ZVT transmitted field alternates between transmitting very steadily in one direction; e.g. North Pole pointing into the ground; then rapidly switches to South Pole pointing steadily into the ground, then back to North and so on. Figure 2 shows a comparison between the ZVT VRM soil signal and the nearest equivalent PI soil VRM signal; both transmitted magnetic signals being bi‑polar, with the same fundamental frequency and same rapid change of magnetic field period. It should be noted that the PI receive period is half that of the ZVT period, because the PI system shown in figure 2 transmits for half the time and receives for the other half of the time, unlike ZVT that transmits and receives simultaneously just about all of the time. The important difference in the VRM signals is that the PI signal decays away substantially faster than the ZVT system. This indicates that the receive signal for PI is less sensitive to longer Time Constant (TC) components compared to shorter TC targets than ZVT, and this is one of the main reasons why ZVT technology is better at detecting large nuggets compared to PI; another main reason being from the double length receive period in ZVT compared to PI for the same fundamental frequency. I can easily get lost in their technical mumbo jumbo.

The GPZ is like fine wine, it's only improved with age. 🙂 it's disappointing they're competing with themselves. All it does is pushes up the price, inhibits development, slows product releases and restricts products as they don't need to compete. Competition supercharges development. They're losing their crown with VLF's quickly if it's not gone already, now competition needs to come into the gold detector market the same way, I'm probably dreaming but it'd be beneficial for everybody but them. ZVT is at the infancy, there would have to be so much more they can do with it. PI, not so much.

I'm sure with time I'll come around a bit, I do like it, it's just not going to take the crown as easily for me as it has for some others, and I doubt it ever will as I've pointed out I hunt in quite bad EMI areas, why use a DD on the 6000 when I can use my normal coils on my 7000 and not be troubled by the EMI and retain my full performance, there are plenty of reasons I prefer the 7000. Really looking forward to some more coils for it though, one less thing to worry about failing too with the number of faulty stock coils a little aftermarket will give a bit more assurance there plus I like a few of the sizes available from the aftermarket guys over the 11" round. What it does do is point out people have different needs in different places and as we always say, no one detector does it all. if I lived in the USA I'd likely think it's the right choice for me though, just look at Steve's gold and the gold some others have posted, beautiful stuff and obviously some of that stuff is the GPZ's weak spot. Our water worn little lumps are no trouble for the GPZ, although it appears quite a few are trouble for the previous GPX 5000/4500. I think everyone should just be happy with their own choices, and they likely have reasons for them and enjoy whatever detector they're using. Steve was a straight shooter on the 6000 from the start and for that I'm very appreciative, I just didn't like missing out but I'll give my 6000 plenty of use, it's so light it can tag along in my backpack especially with a smaller coil on it. We all like certain detectors for certain reasons, not all of our reasons are the same.

The only association with King I have with it is the Burger King Whopper! 🙂 Just kidding, it's a decent detector but not promoted to King in my kingdom yet even as someone that chases the smaller gold which it's known as being so good for, we'll see how it goes with time, more use and some aftermarket coils! Ps, that ugly whopper may contain cabbage instead of lettuce if you're in Australia 😛

So it's the ground causing it and not the nugget? I had it happen once with the GPZ and put a video on here at the time showing it but I'd already thrown the nugget in the collection by the time I did the post and had no idea which one it was so I wasn't able to replicate it again. I never tested the nugget once out of the hole so I didn't know what caused it, I assumed something odd with the nugget not the ground.

You should video and put on YouTube that nugget going over the coil in an air test at various depths, it'll be interesting to see what happens. Unfortunately once you got it out of the soil it never went near the coil, it's a very unusual thing to happen with the inverted signal.

It's very easy for me to compare depth on deep targets, we have a lot of deep coins around here and I can assure you in my soil the 10x5" is nowhere near as deep as the 11" coil, but I wouldn't expect it to be, that'd be expecting miracles. The 11" maintains ID's to a much greater depth. A guy in NZ at the moment is trying to sell his Coiltek 15' coil for half retail price and only a few months old, it's oh so temping to buy it as I do mostly only hunt deeper targets but I've never seen a good review on it other than those done by Coiltek associates. A friend took about 8 months to sell his 14x9" Nox coil and had to take under half what he paid for it to sell it. The other two sizes are the lemon's, the 10x5" is a great little coil.

I've taken a bit of a renewed liking the to my GPX 5000 at the moment, it's threshold is music to my ears after listening to the death metal rock concert the GPX 6000 produces and now it's winter the beaches are devoid of people and prime for the picking. Our beaches don't have all that much junk other than the targets like bottle tops and pull tabs that I'd be digging anyway with a VLF if I was chasing rings so using a PI on the beach here isn't such a bad idea for the superior depth and beaches being easy digging, I've walked over 200 meters up and down a beach a few times in the second biggest city in the South Island and the spot was only a few km's from the city center and not hit one target at all, the beaches are just not covered in trash like some places so a GPX is a good choice of detector. it's about the only reason I have a small regret of getting rid of my QED, it was a decent light weight beach PI that could use GPX coils. This is why this Detech Concentric seems worth the investment, it's only one decent not even good ring find to pay for itself. We also have a lot of black sand beaches and more mineralisation on the beaches than we do on land in most cases even the beaches around here without going to the west coast's near pure black sand beaches are more tricky to deal with for a detector than the gold areas nearby so using the GPX makes a lot of sense. This 18" Detech is much cheaper to buy from Bulgaria which is cool, even though it's got a long ride to get here it's significantly cheaper and being so light for it's size should make a decent beach coil.

We had a couple of acres in Brisbane / Australia and all the houses surrounding us also had a few acres of land, we also had a big reserve bushland area across the road at the front and often had kangaroo's in our backyard usually after 4pm they would show up. One thing we always did is made sure our little dog was inside as he was a little Maltese terrier and felt the need to act tough and chase them around, the big red ones were a bit more bold and would try attack him so once we learnt that we had to keep him locked inside whenever they were around, we were well fenced but that means nothing they hop right on over even a 6 foot fence. The little dog turned into a bit of a nightmare there as he was always chasing down wildlife, had a few close encounters with snakes too with once him carrying one inside that he caught and eventually it was a spider that bit him that sent him to doggy hospital for 9 days. He ended up losing his dog door and we had to control his outdoor movements, I guess its what inspired getting rid of that house, as I said everything in Australia wants to kill you!

I'd say history was the reason, how many people wanted to use the DD on the older GPX series? I just went straight to aftermarket mono's with my GPX. I'd ordered the Coiltek 10x5" Joey before my GPX even arrived 🙂 The DD's vastly improve the 6000's EMI handling though, and the 14" DD was a real surprise with how sensitive it is on the small gold. A bit of market research will show the manufacturers DD's would be in high demand for the 6000.

The heel and toe are more sensitive as the windings come closer together, it's the same with all elliptical coils, but then for outright depth on larger targets the center of the coil is the deepest, it's only on small targets the heel and toe are deeper. For the 6" the most sensitive spot is always the very middle of the coil regardless of target size. For gold prospecting the elliptical is very beneficial if you can't get the center of the 6" over the target due to rocks or bushes. I think both coils are very good, each have their strong points. For outright small gold sensitivity the 6" seems best though.

Yep, $423 AUD for the coil and $31.60 AUD for shipping. I bought my Detech Arrow from them, they use quick shipping too. Thanks for the tip.

Convinced me too 🙂 Should have known, it seems the share many of the GPZ Concentric characteristics. I'm betting it's better in EMI too? They're certainly a good price. http://phasetechnical.com.au/product/detech-18-concentric-coil/ They might make a really good beach coil too. I've only got so many purchases I can get past the boss at a time and a few other coils are necessary at the moment but would you be willing to ship one of these babies to NZ at some point in the near future Nenad?

oh, Iphone, sorry to hear!

The middle is not as sensitive as the heel and toe on tiny targets nor as deep, as the targets get bigger the middle becomes the most sensitive and certainly the deepest part of the coil on bigger targets, as someone intending to use it for coin type targets this will not be an issue with you and in fact it's a benefit of the Coiltek to those who use it to hunt small gold having the really hot heel and toe. I haven't used mine for coin type hunting as I require the most depth possible so little coils serve no purpose for my coin hunts and if in a real junky area it makes more sense to put the 6" on rather than the 10x5" as the footprint is smaller, less chance of two targets under the coil at once. These are the sorts of things you've got to weigh up when you decide which to buy, both work really well, never seen someone break the ears off a 6" so it's likely just a problem with the bigger coils maybe sometimes due to people leaning on the detector getting up from a dig causing fractures with the bigger coils. Never seen someone break the Coiltek ears. Either way you cant' go wrong, both are good coils.
