  1. I'm not sure if it's coincidental but since the update I've run into a number of areas that cause a strange oscillation on the GPZ. Basically, I can set the coil on these pieces of ground and not move it at all and it will just go "wee-woo-wee-woo" constantly and loudly as if there is a target underneath, it never balances out, manual or auto. Rebalancing over the ferrite does not seem to affect it, wether the ferrite is over that spot or away from the spot. At first it was small spots and I thought it was EMI related, but now I've found entire washes that do it, yet the next wash over is fine. I was inclined to think it was due to salt, but there is so little salt around here that I went ahead and tasted some of the dirt (yep) and it wasn't salty. Usually I can taste salt if its bad enough to interfere with my machines. These washes have a lot of black sand and a lot of banded iron formation chunks laying about. usually running in normal and switching to difficult takes it away for the most part but sometimes it's still there. Just odd that it never balances out. Has anyone else run into ground like that before? Most bad ground won't sit there and oscillate if you stop moving the coil even if its bad enough to not balance out.
  2. Over on Rob's forum at http://forums.nuggethunting.com/index.php?/topic/11709-gpz-customers-scores-nice-3-ounce-specimen-at-over-2-foot-deep/
  3. G'day All This has happened five times now. While detecting in normal/general I will switch to difficult mode and then get an audio blank - no sound, nada, niets...... There is always the short audio blank with the change of mode but this one just kills the audio all together....... I have to restart the Zed to get my audio back (audio thru wireless module not headphones). It does beep to confirm that it has changed modes, then deathly silence. Anybody else had this problem? Cheers BB
  4. Jonathan Porter, on 24 Oct 2015 - 8:55 PM, said: I was surprised I did not see further discussion of the information JP presented in the last sentence of the above post. I thought it was quite significant when compared to the older firmware version which dumped anytime the Quick Trac button was pushed. Just thought I'd give you another chance to read.
  5. I am writing a series of tips and "how to" blogs on the zed GPS system. Sure it can be improved, but it is actually something I am finding it to be useful. There is something to be said for it being up front and in my face at all times that makes its use compelling. I like it.
  6. When the upgrade first came out, a lot of ZED users were reluctant to change. I for one, thought if it was recommended, I should do it. I personalty believe it is more stable and more sensitive. I started to find very small pieces of trash in some areas that were virtually target free and some gold that was missed by some competent ZED users. The seven smaller pieces were found at Rye Patch and the others were found close to home in a very pounded area with all kinds of detectors. These were all found after the upgrade .
  7. Over the week I went detecting up in the high country before the storms hit. The soil was damp. All of the downed trees and wood debris was also wet. The gpz squaked all day on everything wet. Had to cut the sensitivity back to tone it down. Was running high yield,sensitivity about 9-14. High smoothing. I found 4 little dinks. But the wetness slowed me down a tad. I was being real meticulous too clean out this patch. Nothing was repeatable on the false signals. But just wondering if anyone else has had similar experiences?
  8. On the Minelab website at http://www.minelab.com/usa/treasure-talk/gpz-7000-ground-tracking-software-update "It’s now been a couple of weeks since the update was released and there are already some good reports coming in from around Australia, where many users have carried out the upgrade and seen noticeable performance improvements. For everyone who has not carried out the upgrade yet – I recommend you do so, along with using the yellow ferrite as part of the ground balance procedure. This will ensure you maximise your GPZ’s ability to extract gold signals from the ground noise." Original software – February 2015 (Control Panel: 1.0.8-57) Ground Tracking Update – October 2015 (Control Panel: 1.2.8-98)
  9. I spent 3-days in Rye Patch and I was suffering with the nosiey wet soil, on day one! What a change in conditions from the week prior. So I, updated my GPZ that eve, to seek some help and I did notice a somewhat smoother machine on the following days hunt. One of my hunting partners did not update and had a great hunt, but was checking out more hot spots with his pick than I. Until the next hunt! LuckyLundy
  10. Hello all, Peter in Australia, I have just joined the forum, so my first post. A bit of an old post, I just came across Lunk's Zed audio settings posted, 01 April 2015. And WOW the 0.065 gram test piece I have was instantly noticeable the way it jumped out at me. http://www.detectorprospector.com/forum/topic/830-lunks-zed-settings/ I would never have thought of trying this way. Thank you Lunk. Any more up dates on these settings? Any thoughts from others using these settings? Can't wait to get out into the field and try them out. Cheers Peter.
  11. Have no ferrite. Would firmware Ver 1 be better to use than Ver 2? Is ferrite super important to ground balancing in Ver 2? I am thinking of reinstalling Ver 1 until I get the ferrite. Thoughts?
  12. Minelab are pleased to announce the first software update to our GPZ 70000 detector. This free update incorporates a new Auto Ground Tracking Algorithm resulting in improved Auto Ground Balance functionality. This GPZ software update improves the detector’s ability to track to the ground, such that more of the audio you hear is from gold nuggets. Resulting in - More stable threshold Higher sensitivity Less false ground signal interference Precision ground tracking More gold found This update also maximises achievable detection depth in any given soil type by delivering improved tracking of the yellow ferrite when ground balancing. Updates can be done easily via Minelab’s XChange 2, or manually via a file transfer method when XChange 2 is not available (e.g. if using a Mac).There is no need to return your detector to a Minelab dealer. To download the October 2015 software update or to obtain the pdf version of the brochure below go to http://www.minelab.com/usa/metal-detectors/gold-detectors/gpz-7000?view=downloads If for some reason you have concerns you can also roll back to the original software version at the same page (January 2015 Firmware)
  13. Paying your dues at one of America's most pounded gold bearing ground, is no joke! Thousands of acres of land to swing your coil, it's a daunting thought of where to start your hunt if you don't know the area. I put in numerous hunts with no rattle in the poke bottle. But, you start learning as you pickup a nugget or two and the puzzle pieces start to fit. My buddy Rudy and I, hit Rye Patch for a 7 day hunt, we only lasted 6 days! I don't know if it was the heat during the hunt or the beers after the hunt, but we couldn't do one more day! We both swing the GPZ, but use total different modes, you may have heard me say you can't run this machine wrong. Find what modes and setting you like and master it. We'd call each other over to listen to see if one of ours ran better than the other on whisper nugget signals. We each heard, the smallest signals we could find for each other and finally gave up the challenge of the best settings for the GPZ. The one thing in common is a very slow swing of your coil and a good pair of headphones (not the stock ones, another story). Well back to our hunt! Nuggets where biting here and there, but we couldn't land one over a penny weight, several are close. But, in our book if it's not a dwt'er its a dink nugget. Dinks are the bread and butter, but we wanted some steak & lobster nuggets. Well late afternoon on the last full day hunt, Rudy radios me to get the shovel from my truck. As I'm getting the shovel a couple of other fellow prospector's introduced theirselves to me and I lead them with me to Rudy and his deep hole. A couple of good shovel fulls of dirt and the target was out. 7.3 dwts at 16" deep on a old pounded patch...Priceless! We had a blast on our 6 day hunt and we met some new friends in the high desert search for gold. Our total Wieght was a little over 27 dwts. Did I see there is a new download for the GPZ...do I have to...lol. Until the next hunt, low and slow LuckyLundy
  14. On Chris' AZO forum at http://arizonaoutback.ipbhost.com/index.php?showtopic=12293
  15. A post below from an Aussie forum, I have my ground balancing pretty much sorted but do have the occasional hassle in various areas so I hope there is some truth in the rumour! http://golddetecting.4umer.net/t22605-gpz7000-up-date "Hi fellow 7000 swingers, I heard on the grapevine today that either tomorrow Friday or next Monday that Minelab will be announcing the release of an up-date for the 7000; something to do with improved tracking/ground balance, the exact details are still under wraps. Like most here I will be very keen to see what improvement/s they have been able to come up with. Stay tuned. Cheers, AUoptimist."
  16. G'day all, Been some time since I posted on this site and have followed the GPZ threads with interest and how it now compares to the GPX. In one particular thread I read the GPZ Audio Smoothing when set to its OFF position is similar to a Stabilizer setting of 20 on the GPX. Therefore my question is in relation to the GPZ Sensitive setting, which is like the Gain setting on the GPX, and since both detectors have their range between 1 and 20 would you say the GPZ Sensitive default 9 setting be the same as running a Gain of 9 on the GPX 5000?, Thanks in advance.
  17. I know Lunk covered this last spring, but I want to reiterate. This morning I got the classic faint mew tone, repeatable in both directions. This is the kind of tone we live for, I knew it was gold because I was out of the trash zone and it was obviously not a surface target. I was running HY, Normal, smoothing off, gain 12. I decided to play with the settings a little. First I switched to HY, Difficult, same sensitivity. The target was barely audible and I doubt that if I was in regular prospecting mode it would have been sufficient to stop me. I already knew it was there, so I had too much advanced knowledge. Then I switched to General,Normal, same sensitivity. The target was still very clear. I toggled back and forth, clearly the Difficult setting faded the target. Low Smoothing had little effect, but I was in very quiet ground. My conclusion, at least for this quiet ground in Sunny Yuma, use Difficult as a last resort. The nugget was about 5 inches deep.
  18. We had a cold snap in sunny Yuma, 78 degrees at 0530. I went back out to the previously hammered gold drywash zone. I found the 2 bigger pieces 2ft apart on the shoulder of a worked out gulley. They were 8 to 10 inches deep under some drywash tailings, resting on a layer of hardpacked clay. I gridded the area with no more luck, although I had bootscrapped one spot a couple times. I decided to plug in my earphones and jack up the sensitivity to 16. I gave the area a good go no new targets, but I kept going back to the bootscrapped spot. With the threshold at 1 I was getting a faint stutter in one direction, but nothing on the backswing. I used my pick to pull down a couple inches of dirt. Ever so faint signal in one direction. I decided to settle this thing and dug up a foot square down about 4 to 5 inches. Finally, a repeatable signal. I got to the hardpack layer and after a couple tries got it in the scoop. Really tiny so I measured the depth. I measure 9.5 inches. Now I can't say that nugget was actually resting at that depth, but he was damn close. He weighs in at .1 gram. The total for all 3 nuggets was 1.1gram. I'm liking the Zed with the threshold at absolute minimum. The background is chattery, but a target breaks through with ease.
  19. Greetings. The Gpz 7000 is virtually a dead horse in ground that are saturated with a high salt content. Either salt lakes or just grounds that have a high mixture with salts will give the ZED a bad case of the howlees. The tracking on the ZED is slow and unforgiving in salts. Over highly mineralization the ZED works great and proper adjustments it will do what's it designed for to find Gold. For those who are going to be searching very salt saturated soil or lake beds then you may want to stick with your 4500 or 5000's. The Gpz will find gold down to a 0.05 gram and does better and deeper, but it does have it short fall but one hell of a good detector. AC
  20. Well, the GPZ 7000 has done again what nearly every new Minelab model has done. Introduction, big debate and controversy, slowly fading to acceptance of what is. It does surprise me how quickly the controversy just cut off however. We had one last burst from a couple guys on Finders Forum who were hating the GPZ, they sold them, and that has been that. Everyone now seems to have moved on and it is hard to find much discussion at all pro or con. Some people seem to think that means sales have not been that good but I do not think that is the case at all. I am more surprised at how many people seem to have a GPZ now because I thought the price would be a real obstacle. I admit to secretly hoping that might prove to be the case (sorry Minelab) as it would not hurt my feelings being the only guy out there swinging a GPZ. Just the opposite however - seems like everyone and their brother has one. Oh well. There is much a person could complain about but despite a couple tries I never could get klunker to really let loose on the forum with his unfiltered thoughts on the GPZ. The reality is all the negatives tend to get offset by one basic fact - the GPZ is a very powerful metal detector. I sold almost all my other nugget detectors and have been swinging the GPZ almost exclusively ever since. It packs both small gold sensitivity and extreme depth into one unit with one coil, and given that I can only swing one detector at a time I have every confidence it is what I want to be using. The only exception is in heavy trash, where I still might switch to a VLF. So those of you with a GPZ. Any thoughts now that some time has passed? Anyone that used one and still just really prefers to use a GPX or something else instead? Come on guys, let it all hang out one last time and give your best summary of what you think about the GPZ for those out there who may still be mulling the whole thing over.
  21. Can the 3030 use the WM 12 or the 7000 use the WM 10? I tried with the 7000 and the 10 and couldn't get a connect. I'll be trying again. Anyone else try it?
  22. I have commented in the past that as far as how it actually acts in practice the Minelab GPZ 7000 reminds me more of a "super VLF" than a PI detector. I want to carry that analogy a bit father in an attempt to help clear up a common question about the detector. What Gold Mode should you use? Minelab makes a unique prospecting VLF called the Eureka Gold. What makes it unique is that is can be switched between three frequencies - 60 kHz, 20 kHz, and 6.4 kHz. The high frequency 60 kHz mode is the hotter on small gold and in mild soils also gives excellent depth on all other sizes of gold. If you were to air test the detector this is the mode that would air test the best on a wide range of targets. It is the go to mode for mild ground and at high gain levels can be very impressive. The problem is a hot high frequency setting that really lights up the gold can also light up bad ground and hot rocks. This in turn can obscure desired targets. If the ground mineralization is bad enough penetration is severely impacted because sensitivity/gain levels must be drastically reduced in an attempt to reduce the response from the ground and/or hot rocks. If this is the case going to the 20 kHz mode will make the machine less sensitive to ground feedback and hot rocks. Some sensitivity to the smallest gold is lost, but by reducing interfering ground responses depth on larger gold is retained. In the very worst ground and hot rocks however even 20 kHz mode can be too hot. In a worst case scenario going to the low frequency 6.4 kHz mode can eliminate all but the absolutely worst ground feedback. Sensitivity to smaller gold again takes a hit but depth on the larger gold again is to a large degree retained under difficult conditions. The coil employed plays into this. Larger coils "see" more ground and are more susceptible to the ill effects of bad ground. This can be offset by using lower frequencies. In fact, the 15" WOT coil for the Eureka Gold comes with a note saying that best performance can be expected in the low frequency 6.4 kHz mode. The problem is that people are usually thinking about what mode gold responds best at. It is often more useful to think in terms of in what mode ground and hot rocks will be less inclined to create issues. If you can't get the machine to play well with the ground then finding gold becomes a bit of a moot point. Think of the GPZ High Yield Mode as being the equivalent of the 60 kHz mode on the Eureka Gold. General would be the equivalent of the 20 kHz mode, and Extra Deep a match for the 6.4 kHz mode. The GPZ Gold Mode names confuse people. Extra Deep should be the deepest, right? Well, yes and no. In mild ground General will outperform Extra Deep. However, in extremely bad ground or when employing yet to come larger coils Extra Deep will reduce or eliminate ground noise that keeps General from attaining the depths possible in milder ground. It is not that Extra Deep goes deeper. It is that Extra Deep is quieter allowing nugget signals to not be masked by ground noise. Which in turn delivers more effective depth. People are constantly confused I think by the fact that performance of metal detectors is not measured in absolute terms except in air tests. Which is why I consider air tests to be generally worthless when evaluating prospecting detectors. The most important thing by far is relative performance, that is, performance relative to the ground and hot rock situation. Machines can deliver spectacular air tests and fail miserably in the ground. In fact, the best air tests are most likely to fail in the worst ground. So for me High Yield is the go to mode because I frequent milder ground locations and unfortunately smaller gold is my bread and butter. In hotter ground where average nugget sizes are larger General might be the go to mode instead. It just depends. Extra Deep is a special mode that is very, very much equivalent to that 6.4 kHz mode on the Eureka Gold. It is going to actually be the less sensitive mode in mild ground. It only shines in the worst of ground and even more so when using a larger coil. Frankly, in 99% of the situations one might encounter with the stock coil High Yield and General are going to do the trick. Extra Deep is only really going to come into its own when a large coil is introduced for the GPZ 7000. If a person is running a large coil in really bad ground searching for multi ounce nuggets, Extra Deep is likely to be the go to mode. Hope that helps.
  23. So when you get out and run your detector in the right places, this is what you can find: Its the gold I've been getting in various locations in Plumas and Sierra counties in July, August and early September - just going out and prospecting for a few days at a time. I figure I'm probably out digging about 1/3rd of the time. This is just from my detecting in California - it does not show about a half ounce of fines and small bits from some days of dry washing nor does it show the gold I have detected in Nevada. All of this gold was detected using either Minelab's GPZ 7000 or the SDC 2300 - I find I am using both. I use the GPZ in areas with more open country and little in the way of trash, and the SDC 2300 when I am working in trashy areas. The SDC does not have any iron discrimination, but its faster to pinpoint and get the trash out of the ground when you are digging a lot of targets and you may find multiple trash targets in a single swing of the coil. I have used the GPZ in what were once trashy places after the trash has been cleaned out.The two make a great team. The largest nuggets across the top are 0.52, 1.10 and 0.41 troy ounces from left to right. Finding these big guys was very exciting - though every one is a joy to discover.
  24. The Minelab CTX 3030 has a clock on screen, and so I have puzzled over why it was removed from the GPZ 7000. I finally noticed the other day that the GPZ 7000 does have a built in clock but it is hidden. To get the time the GPS must be turned on, and it is off by default. Go to the Settings screen and activate the GPS. You also need to set the proper time zone in the Preferences/Time Zone screen. This does not adjust for daylight savings time so set accordingly. The easiest thing is just take your best guess then double check the time once you get this running and adjust if need be. OK, once you have a satellite fix you are good to go. I am always tracking myself anyway so my GPS is always on. Once set for on it stays on by default when you power the detector up unless you go back and shut it down. Now, push the red Store Button on the lower right control panel. This will bring up the Create Geostore page, and the Create Findpoint menu item will be highlighted by default. Select the Create Findpoint menu item and you will see this screen, and there is your current time! Normally at this point you would create a Findpoint by pushing the selection button again and adding the target (nugget) depth and weight. Instead, once you see the time, just push the Back Button on the lower left control panel, and get back to detecting. A Findpoint will not be created. In practice you push the Store button, then push the Enter (Checkmark) button, see the time, and then push the Back button. Done!
