I like detecting for a variety of gold and really enjoy finding the stuff many higher end detectors can't see. I don't know yet, but feel the extra capabilities of the GPX-6000 will open up some of these areas I hunt with the VLF's to get even more of the gold and at greater depths or in worse soil conditions. As long as I am getting more gold, I'm happy. Will the new GPX-6000 see this kind of gold or act like all other PI's and the ZED and not see at all?
I recently recovered this 4.2 gram speci with the EQ-800 while running the new CoilTek NOX 15" round. My goal was to find a piece of gold with the 15" and I met that goal.
Part of some other testing back at base proved why I still like to take 2 detector technologies in the field. This particular beauty was found right in the middle of a GPZ-7000 grid area, along with 4 others while using different coils on the EQ-800. All 5 pieces specimens have visible gold and a couple how quite a bit, but to the point.
The reason I found them in that gridded area, is because the GPZ-7000 does not respond or on a couple right near 1" and that's it. I teach folks this in my classes, as well as try to educate others on the goods and the bads of different detectors and technologies. Sometimes I get detectorists who are good hunters with their detectors and have success, tell me I'm full of BS and their detector will find it.
I made a post on my FB (Gerry McMullen) and shared a pic of the find along with the true comments of, the GPZ will not see it. Between the private messages and or public posts, I was immediately informed by a few of BS and even told how I must not know the GPZ-7000. One well known GP-3500 hunter even said he guaranteed his 3500 would hear it.
I know gold detectors and I know how to find gold with a variety of gold machines. No I am not the best, but I most certainly can hold my own and I learn to adapt really fast to a new area. Traveling to different states and countries to hunt for and find many different kinds of gold has helped elevate my detector knowledge and skill of many models of detectors and the differing Au rocks I have collected.
So here is hoping the GPX-6000 with it's GeoSensing can respond to this little beauty. If it does, I know of some areas I'll be swinging the 6000. If it is like the GP-3500, the GPX-5000 and the GPZ-7000 and misses it, that fine too, I know what they can't see and realize it, I will also know where not to use the 6000.
Bottom line for everyone. Please learn the kinds of gold your detector is good at finding and what it is not, so you aren't wasting time in those areas. Or be sure you have at least 2 different detector technologies.

I was on the development team for both the Minelab GPZ 7000 and GPX 6000 detectors. I’m also a well traveled detectorist, familiar with the type of gold and ground conditions commonly encountered in the U.S. There are questions about how these two detectors compare, and I think I am ready to make some recommendations for U.S. prospectors. I make zero claims about these opinions applying to Australia or anywhere else. This is just my take on the current situation on the ground in the U.S. as regards these two metal detectors. This commentary is aimed specifically at a person considering both models, never having owned either one. You want to step up from what you have, to either the Minelab GPX 6000 for US$5999, or the GPZ 7000 for US$7999. What do you get for the extra $2000, and is it worth it?
Famed detectorist Lunk was in the area, and gave me a yell a few days ago. We met for a couple days of GPX and GPZ hunting. I’ve never hunted with Lunk, and wanted to, as I admire his detecting skills. He of course wanted to see the 6000, so we got together to do a little testing, and to compare thoughts.
The reality of nugget detecting in the U.S. is that we are on the tail end of the electronic gold rush. We never had the quantities of very large nuggets that Australia had, and many locations are nothing but small gold. People do not like to hear it, but the bigger the gold, the easier it is to find. The larger it is, the faster it goes away. Each nugget detected is one less to find, and anyone who has worked the goldfields for many years knows the patches are playing out. The determined detectorist can always find gold, but finding large nuggets, or large quantities of gold, is an ever more difficult task.
The technology is mature, with gains there hard won, and usually only on a certain class of gold, like specimen gold. The technology to find large, solid lumps of gold, is not improving as fast as the nuggets are depleting. Ultimately the geology rules, and the U.S. has many shallow placers that do not extend to depth. In the areas I hunt, gold is found down to, and on top of the caliche layer. The old timers and more recently bulldozer scrapes show that more often than not, gold does not extend at depth. A deeper detecting machine offers no real benefit in the expectation of super deep, large nuggets.
In my opinion, straight out of the box, the GPX 6000 is the better choice for most people in the U.S. who are considering the two detectors. The GPX 6000 simply does a better job without modification, on bread and butter, 2 gram and smaller gold. On larger stuff, the GPX 6000 will almost always hit the same gold the GPZ 7000 will find. I no longer recommend the GPZ 7000 to anyone but the most committed power users. Literally, the people who must have the most power obtainable. To actually make this happen, you will need not just a GPZ 7000, but some aftermarket coils for it to really get the full potential out of the machine. If you are that person, budgeting $10K for a GPZ 7000 and a couple accessory coils is not crazy, or out of the question. If you want to get the most power you can buy, go GPZ 7000. If you are convinced large multi ounce nuggets teams in at depth, and you want to get them, a GPZ with some aftermarket coils is probably your best bet.
0.037 gram bit, decent signal, not surface
I argue however that for anyone else, anyone else but the most committed power users, that the GPX 6000 is the better choice. I’ve said I have no issue hunting with GPZ owners as a 6000 user. I’ll now go a step farther, and say that as far as I am concerned, stock detector to stock detector.... I think I have the edge on the GPZ user for finding gold in the U.S.
The GPX 6000 out of box will clearly and easily hit small gold targets the GPZ 7000 misses entirely, with performance more like GPZ users experience when running a small aftermarket coil. The GPZ can match or exceed the 6000 on small gold with the use of the aftermarket coils, but you have to invest even deeper than the already large $2000 differential. The GPX 6000 with the 11” mono is close to Gold Monster sensitivity, though a smaller coil is needed to really make that obvious.
Further, the 6000, even without the DD coil, handles salt ground better than the GPZ 7000. Finally, the 17” mono can be added to the 6000 and still be under the price of the GPZ 7000, so you have a three coil machine for less than the single coil GPZ costs. The 17” mono is almost as hot on small gold as the 11” mono, while giving excellent depth on the larger stuff. It's light weight, and small gold capability, make this a near perfect patch hunting coil.
To sum up, if dropped on random locations in the United States, and I have to go with one of these machines, and my buddy gets the one I do not choose... he can have the stock 7000, I’ll take the 6000. I honestly think it’s my better choice for getting the most gold signals out of the majority U.S. ground.
Just my opinion, and feel free to argue otherwise. But from what I saw the last couple days, I have nothing to fear from going head to head with GPZ operators in U.S. ground. If anything, I think I have the edge. Toss in aftermarket coils and that changes, but stick to stock, I’ll choose GPX 6000 every time, not just for ergonomics, but for actual performance. If the gold in the photo below is your bread and butter, the GPX 6000 is a great way to go.

Out detecting with mates and took the opportunity to have a play with the new GPX 6000, and matched it against the older GPX 5000. Not a like for like comparison as the 5000 had a 12 x 8" Evo coil on it, but the results were interesting anyway....
A bit of a 'non-scientific' test of the two machines, to see how the new GPX 6000 performs. Done using two small nuggets and a sliding rod.. bit of fun!
It’s exciting when a new detector emerges, none more so than a new top notch gold getting machine from Minelab and the new GPX 6000 is as exciting as it gets. Just a little reminder about the virtues of the GPZ/14” an older brother he may be a little thick in the middle but this heavyweight can still sniff out a few crumbs in the pounded terrain in the desert of Gold Basin Arizona, from a few recent hunts.
