Got the 7000 back yesterday after it died on me a couple of weeks ago, and today I managed to get these two. Maybe I should send it away for repair more often. Not every day do I come home with 1.7 grams of gold

My detector failed a couple of weeks ago. I posted it off Monday last week and got it back Thursday this week. Took it out for a quick spin yesterday and all working fine. Thanks Minelab

Hi all, some of you have known me for many years as Mlgdave, owner of Goldbay.com and now I also own The Colorado Quartz Gold mine in California and ramping back up to run and mine 140 and 180 feet underground. This week me and my partner worked an old stope and found and extracted a killer piece! (more to come) I am living at the mine full time and should have some good stories and finds for you guys over the next few months/years Mlgdave

Overall, the GPZ is an awesome tool and I have been extremely happy with it since I purchased one about 6 months ago. But I thought I would gather what things people wish would be included as a future option/improvement such as software upgrades/gps options ... etc. Maybe I will forward the link to their marketing department (since I hear engineers are so difficult to work with ;p) Please list only your top 3 wishes for improvement/options/upgrades in order of priority ... if they are the same as others then that is fine. It shows we want similar things. My wish list: 1) smaller coil option - anywhere from 8-11" 2) software update allowing storage of a secondary settings (similar to GPX5000) 3) maybe a clock on the front screen

Hi guys, in your opinion, what is the best vid on youtube for someone just starting out with the gpz? Maybe something that walks you through the start up settings and stuff.

Wow, I'm sure others have found smaller (and I did find one flatter than this on Rye Patch) but Zeddie continues to amaze me with how deep the 14" coil will find tiny gold. My 5000 wouldn't have found this without the Sadie and not at this depth (I believe it was about 6" or so)... I don't mind digging up tiny stuff like this, provided it's gold and not the small tiny wire slivers I seem to find most of the time (black for contrast, dime for size). I of course didn't make wages, but I don't care, this Summer I've dedicated to learning the machine, not expecting it to produce so being able to see tiny gold come up really builds trust in Zeddie that I didn't have at first (I sold my 5000 to force myself to use and learn to love Zeddie and I'm starting to be ok with that sale). Thanks for listening friends. Jen

So, just one more issue during my Outing... I have been in the habit of tossing my ferrite on the ground...foolish me. They break into many pieces...so no more tossing... I wonder if the ring can be super glued back to one piece and function correctly? Or is it more like a metal ring that no longer gives the same signal once the circle is broke? Or do I need a new one? so many questions.... fred

Editors Note: This topic was split from the following thread - http://www.detectorprospector.com/forum/topic/3923-semi-auto-gpz-ground-balance/ I believe there is a lot of reasons of trying to turn GPX into a GPZ. They wont be never the same thing since they are in different technology . But anyone would like to walk around with an more affordable machine that could pack a punch of the " GREATEST". Im someone who started metal detecting and someday looking to upgrade to a heavier and more powerful machine. So after reading the pro and cons of each one i would pick a GPX over GPZ even if i found a Pound of Gold. -Lightest machine? GPX wins even with a larger coil. -Coils price and more coil options? GPX takes that. -immune to the hottest of ground? GPX i guess wins this since is a PI. Dont know where that ground exist but i know is out there. Okay so i have seen running a GPX with one of the newer coils could match the performace on depth on sub-gram nuggets and up. Now the GPZ would clearly stand out on tiny, spongy and specimen gold. But wouldnt you have enough money left to even buy a SDC 2300? I just dont see the reason of boasting a machine for ability to pick up super tiny gold when you need to pay so much for it. That headline for me fits more a GM1000 since its a way less expensive machine.

GPZ 7000 Firmware Installation Procedure (PC or Mac) 1. Download the desired firmware version from the GPZ 7000 Downloads Page. You can update your GPZ to the latest version or roll back to any prior version using this method. IMPORTANT: Ensure your battery is fully charged before updating. Do not turn the detector off at any point during the update process, or the update will not be applied. 2. Connect GPZ 7000 to the computer via the USB cable. A drive called ‘Minelab’ will appear. 3. Transfer the software update file. Open the ‘Minelab’ drive, then copy the software update file into it. The update files end with the extension ".ml3" - anything else is the wrong file. Wait for the file to completely transfer. 4. Disconnect the GPZ 7000 from the computer by ejecting the drive and then unplugging the USB cable. The ‘USB Disconnected’ dialog will be displayed on the GPZ 7000 screen. This can take up to 2 minutes to complete. 5. Upgrade the GPZ 7000 firmware. At this point if the update file was properly transferred to the GPZ, the following dialog is displayed: 6. Select Upgrade to begin the firmware update. A progress bar will be displayed. If you select Cancel, the software update file you downloaded will be automatically deleted. You will need to download the update again (from step 1) to complete the process. If the Low Battery dialog is displayed, charge your battery and start the update process again. 7. Upgrade complete. When the upgrade is complete, GPZ 7000 will automatically turn off. When you power on again, the detector will start with the new firmware. 8. Upgrade failure. If you experience any trouble applying the update, try following the update steps again from start to finish. If this does not work, contact your dealer or a Minelab Service Center. 9. You can also check your detector’s software information at any time via the Version Information function on the Reset page.

Got out to the hills for a couple hours today to have a play with the new software update on the GPZ 7000. Straightaway went to a spot that has variable hot ground that is noisy in the Normal Ground Type setting. The new Ground Smoothing with the Locate Patch option selected almost completely eliminated the ground noise, while still retaining really good sensitivity. It wasn't long before the first target revealed itself with a crisp, obvious response. Only an inch or so into the weathered quartzite bedrock, out popped a small, thin nugget: Next I hit a patch of variable ground that was really noisy; in fact it proved to be too noisy even in Locate Patch, so I turned the Ground Smoothing off and switched the Ground Type from Normal to Difficult, increasing the Sensitivity to compensate. The noisy ground completely disappeared, and within a few swings I had a nice solid target. Three inches down was a chunky, ragged little piece of gold: The new Semi-Auto Ground Balance Mode didn't seem to have much effect in the variable ground that I was hunting. Since this Mode fixes the X-balance, I assume it's meant more for uniformly hot mineralized ground types. The new Salty Soil Ground Smoothing mode was very chattery, even at low sensitivity levels and with Audio Smoothing set to High, so it's very susceptible to EMI, but to be fair I was in close proximity to power lines. All in all, a great update that provides more tools for the GPZ 7000 toolbox.

Hi Every one With the GPZ-7000, 2.5 yrs on and only a single update to fix the GB , Is it about time that the next update is just around the corner ? What is it that you'd like to see in the next fix or performance or what ever etc etc I for one would like to see a similar screen used as the CTX 3030 that shows you what target is what , surely ML should be able to do that by now ? or can they ? Cheers Marty

Interesting. This new Youtube channel popped up recently for somebody calling themselves X Coils It appears to be Russian? and they appear to be working on coils for the GPZ. Here is a peek at the 12" x 10". Personally, that's a bit too similar to the stock coil to interest me - I would rather see a 10" x 8". Still, it's interesting that somebody has managed to make some coils that might work on the GPZ without blowing it up. This is one detector that I will have to let others gamble with first on this sort of thing but I knew you would all find it interesting. Edit - the videos disappeared so I deleted the link. Here is the latest X Coil 2021 News

Hello folks, It's been a long time since I've used my GPZ because I had to move away from the Redding area where I was using it regularly. It makes sense to sell it and use the money for a new computer and engineering software for my business. The machine has around 200 hours and works perfect. It still has the original skidplate, so that gives you an idea of the minimal wear and tear. Can you please recommend a fair asking price so I can then put it in the classifieds with pictures? Thanks much.

I purchased my Zed in mid-2015, and since then I have complained about the display being difficult to see clearly. Then yesterday I realised that it is a "sunlight-readable" display, presumably similar to what is used on some of the later Garmin GPSs. That is, when the display is in full sunlight it can be seen very clearly. I'm assuming most people here probably already know this, but I've mentioned it in case there are one or two others out there who are as smart as I am and taken nearly two years to work it out. Col

This only fits the newer Minelab CTX 3030 and all GPZ 7000 units. Most people like me probably only want a replacement stand but for $15.00 with free shipping it is hard to complain. Except about the stand being so flimsy in the first place! Minelab Kit part #3011-0283 https://store.minelab.com/product-p/3011-0283.htm

Does Minelab limit transferring the warranty to several new owners, or can you just transfer the warranty once?? Talking about the 7000. Also hearing from multiple sources Minelab doesn't really do repairs, they just mail new devices back to you if there is something wrong. ????

Still love my 5000 but it's sadly neglected as of late., the 7000 is just a beast! Walked onto another little run in a wash today in a totally new area. Scored 19 grams in nuggets plus two specimens. * Just belted the species and got 1.4 out of the little one and 4.6 out of the bigger one plus probably about another 3 or so grams in fines to be panned off. * Fly not included in weight

I got out for a quick 2½ hour detect today at a spot where most times I come home empty handed but I know of some nice pieces that have come from there in the last 5 years and I got this half grammer. It`s not so much the size of the piece as the signal it gave off. I run a very low threshold, if I turn down the threshold just 2 numbers I can`t hear it, and this piece came through as very soft electrical interference. From the signal I was getting I had no idea of size or depth and I was disappointed it was only down 6" in super hard gravel. I was hoping what ever it was, it was going to be much deeper. But any day I come home with a rattle in the jar is a good day. cheers Dave

Doing a bit of testing on the new Evolution coil. Some may recall I was skeptical of the newer generations of coils and I said I would post a testing video when I got one of them to test. Results were not entirely surprising for those who don't like watching videos, but overall I am satisfied with the Evo. See below video for summary. GPZ is definitely king of the dinks, but superior overall on all targets too. If I had some crystalline or highly disseminated specimens to test it wouldn't even be a contest. These tests pretty much replicate my experience in the field - on medium sized stuff I am generally getting 1-3 inches deeper with the GPZ which may be like 10% improvements, but on smaller stuff I am seeing more like 40% depth improvements. Evo is definitely more sensitive and deeper than the 17x11 on every piece of gold I tested. Question is whether it's more sensitive then it's direct size equivalent which would be a 15" round mono. I think it would be, I'm guessing it's probably closer to a 16" round or maybe even a little better when it comes to the small stuff which is (like the GPZ) where I think the biggest gains are at since a 16" round mono would probably not pick up the last nugget I tested at all, or if so only right on the edge where the winding is at. What I'd like to test is whether or not it has greatly increased sensitivity to the crystalline/disseminated stuff but I sold all of it that I found this spring. After the last few generations of newer coils, this one seems like the first to make a noticeable change to me, but don't expect miracles. In other words, it's easily noticeable to me, but slight...but in a game of inches that can be everything. I have now made the Evo my default coil on my 4500 and put the 17x11 on the shelf for the first time in 5 years. For long exploratory trips where I spend all day weedwacking nonstop I'll still use the 17x11 because its much lighter.

The Minelab GPZ 7000 is an excellent meteorite detector. At the Franconia strewn field, the three small fragments shown below were "bread crumbs" that led me upslope to their larger parent individual; all were buried beneath the surface.

Just in case you were wondering - from http://www.codan.com.au/Portals/0/investorpubs/Half Year Company Announcement Feb 2015 Final complete.pdf in 2015: "Minelab launched the GPZ 7000 gold detector to the market in February. This is a significant new product platform that has taken five years to develop at a cost of over $10 million." The good news for Minelab is it has paid off as sales and profits for Codan have been up in the last few years after collapsing when the Africa GPX 4500 bubble popped. From the Codan 2016 Annual Report "while sales were strong in the developed world when the product was released last year, the most significant growth in our FY16 gold detector sales has come from the successful launch of this product into our African markets. The GPZ 7000® was launched in Africa in October 2015, and demand exceeded our initial expectations". Since Minelab's parent company Codan is publicly traded interesting tidbits can be found in their annual reports. A few more: "The GO-FIND® is now Minelab’s highest unit seller" "FY17 OBJECTIVES - Release two exciting new products – lower-priced gold machine for Africa and improved larger coil for GPZ 7000®.... Continue investment in product development to create next wave of new products in FY18." Nobody knows for sure how many metal detectors are sold worldwide but Codan alone currently does close to $100 million sales annually in detecting equipment. That does however include landmine detection equipment. Check out pages 19 and 20 of the 2016 report for more details.

A new Treasure Talk blog by Jonathan Porter. "Following on from my last blog about the GPZ 19 coil, here are some further tips to help you get the best from your GPZ 7000, irrespective of which coil you are using. The GPZ 7000 is not difficult once you come to terms with the way the technology performs over the ground. It is a blend of behaviours which are dictated by ZVT technology, the Super-D coil design and the detector’s ability to tap into the full gamut of target information, thanks to being able to run a very low noise floor without any major trade-offs to audio stability."
