  1. I have been painfully considering a purchase of a 7000. Seeing the gold a friends 7000 is getting that seems to be out of reach of a 5000 is giving me reason for this consideration. However with the areas I used to have access to that facilitates the use of the large coils are being lost due to development and I would have little or no areas to go that there would be a benefit to the large coils. If Minelab would make a small coil like the 11 inch diameter that is stock with all the other models up to the 7000 it would justify a purchased. I wonder if it’s the technology in the electronics that will not work with a small coil.
  2. Seeing some barely-used gpz 7000's coming across the auction block. Weren't there early ones that had issues? If so how were these issues resolved? How can you tell if the unit on the auction block is not one of these? Having not owned one yet I'm a little behind and appreciate any feedback.
  3. Maybe a new thread if you have the time JP. "How to target large, deep gold with the GPZ?" Is it your conservative settings or something different again? How does the audio differ, etc? There are bits and pieces (linked below) that maybe all add up to an answer but if there are any other secrets you want to add JP, I'll listen
  4. Hello Johnathan the GPZ 7000 has been out for a while now, is there any plans to do a DVD. I could see how a soft ware upgrade could potentially make it harder to give any advice on settings as upgrades come along. Or is the whole thing a big head ache.
  5. I updated to the latest firmware in september, sunday when I was detecting I would lose my sound through the wireless, I plugged in headphones and no sound from the machine through them either EXCEPT for turning it on, and also when the WM wireless connects I hear that (but probably from the unit not the headphones) Anyone else have issues, I do see 2 other threads but have tried both fixes including updating again. No dice, need the GPZ! mlgdave
  6. With several GPZs working in a small area, is there a recommended auto tune procedure to tune each other out? Norm
  7. Just returned from my annual trip away (that's another story for another day), I've been out 3 times detecting since getting home and two of those were training sessions. Yesterday morning it was my turn to do my own thing for a few hours before the heat beat me to a pulp. A few minutes later and I had a plucky 1 gram nugget on a continuation of a spot I detected with my son Timothy back in July (got AU$800 worth off there for the session, much to the delight of his pocket book). There is a fair amount of trash and the obligatory shot gun and 22 bullets along with the added hassle of a high voltage power line, so I had to concentrate on the wide broad deeper sounding targets mixed in with the Sferic and 50 Hz noise, 3 hours of this and you find yourself needing a little lay down. This location is also problematic because it is on a slope above a straight flowing gully so the coil is opened up to even more interference dependent on where you are working on the slope. Long story short I plucked some nice gold for the effort which made the little lay down later on justifiable. Interestingly I pinged a solid 5 gram chunk in my old scrape from the 5000 days, a boomer signal for the GPZ and not that deep so can only assume the quieter running GPZ 7000 was clearly an advantage in a high EMI area. Just below it I got a nice deep warble that made my skin goose bump and sure enough 16 inches down a 13 gram slugster came to light pushing the mornings total to 23 grams of 97%-98% Clermont golden goodness. Considering I spent 2 weeks in WA this year without a piece of gold this was pure heaven especially since I have more signals to investigate over the next few days. The GPZ still continues to amaze me, if only it was lighter and more manageable so that other people could tap into its potential more fully. The weight really does detract from good detecting practices with this technology. The Super D coils really do need to be kept above saturation effect for maximum depth on the deeper pieces, the coil sweep also needs to be evenly controlled, all vital methods that are are adversely impacted upon due to too much outright weight for the average user.

  8. Well after getting skunked on my usual areas in Gold Basin today, I was getting the feeling that maybe I should try something new (I move around a lot, as people who detect with me will attest). If I'm not on colour or it feels wrong, I'll move at times several miles and start again..... So, I went to an area that I'd been hoping to try again after being chased out by trash last time.... it dawned on me today, why.... I got out of the truck, did a quick walk up to the side of the hill/bench and fired up Zeddie.... but this time, I thought... I'm not getting skunked today.... let's crank this bad boy up.... I had been running at sense of 10-15 today, depending on the area..... I thought to myself, let's give Steve's Mac Daddy Go Big or Go Home settings a run... In all honesty I'm usually running very similar settings, minus his hi gain. Well up it went.... wow, noise much but I figured.... I had nothing to lose, I'm learning the machine this Summer, I might as well see if i can get use to running super hot..... I did a quick ground balance and away I went... I got less than 10' and heard angels (well, ok, maybe it wasn't angel's but you all know the sound).... BOOOOOO YAAAAAAAAAAA nice rough little nuggy DEEEEEEEP. I proceeded to do a little "Beat the skunk, thank you Steve's settings" dance in circles..... as I was filling in the hole it struck me, why wasn't this found, out in the middle of a huge wide area, easy target... oh well.... then I commenced detecting..... and as I wandered and dug HEAPS of small trash that should have been dug by detectors before me, it dawned on me...... and then... mid thought... WOOOOOOOOOO WOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO oh man.... a pop can, like I need another one of those..... and down I dug...... hmmmm when did gophers start drinking soda, this thing is deep.... and then out came a 73 grain chunk.... oh yea.. oh yea... who your daddy!!!! I then realized, I'd found my first virgin patch, and on Gold Basin no less...... 20 sensitivity is my new normal....... wow, what a huge difference... I've gone from hating a chatty threshold to now realising the power that same noise has..... It was getting late, the patch is hard to get to/from in the dark so I left..... this story will be continued.... (I hope) I'll post updated cleaned pics after they get a bath. $324.00 at $50.00 a gram... I may have an extra ice tea tonight at dinner. Thank you Steve........ for your continued reference in some of your posts (including your one recently with the shovel in it) where you mention this may be an option for some.... it was for me today and is my new norm. Jen
  9. Here it is folks. Loaded with tuning tips! http://www.minelab.com/__files/f/254716/KBA%2024-1%20Basics%20of%20the%20GPZ%207000%20Technology%20Zero%20Voltage%20Transmission%20(ZVT).pdf "A significant technical achievement of GPZ 7000 ZVT technology was in creating the ultra‐stable transmitted magnetic field during the receive period, to ensure that the large reactive component of the soil signal, X, is not detected, in the same way that it is not detected in PI." 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.
  10. Back in the 4000 days and older gent named Bogene (in his 70's I believe) came up with a method of detecting that is basically turning the threshold off, screwing the gain and stabiliser up, and detecting like that. I've had a dabble with these settings but could never get my head around the no threshold part as it just sounds so damn wrong after being used to threshold since Jesus played fullback for Jerusalem. Yesterday we were detecting and old spot and it was noisy. I turned the audio smoothing to low on a few occassions, but don't really like the dullness it gives so went back to the off position, and played with the tuning on several occassions to make a smoother threshold. I had 9 little nuggets in an area I've had the SDC on recently and eventually decided it was a perfect time to try Bogene's setting on the GPZ. I started with High Yield and Difficult, threshold to 1, gain to 20, audio on 8 and scored one of the smallest bits I've ever found. I showed my mate and that was my first Bogene nugget. I tried normal but the ground wasn't that forgiving so eventually settled on threshold at 7, High Yield, Difficult, gain at 20 and audio at 8, and commenced to get another 14 bits. The detector is pretty much dead quiet, except for a very faint hum through the B&Z booster, and the signals are more like a mouse squeaking until you get the coil directly over the target. i found that on the faint ones, a large hole started got the coil closer and the target easier to find. On one signal we were digging I put the coil away from the hole on the ground and it squeaked. I scuffed the ground and moved the coil. That was the next target and next nugget. I would have thought that the coil would have to be over a target to get them, but brushing past some rocks and grass tufts produced a single squeak at times and some moving around of the coil produced an obvious target. I also found while experimenting that the 27 and 28 numbers I was running the threshold at are not the best for small nuggets and 26 seems to be ideal. 25 is where the threshold is in and out, but 26 seems to be the goods. I'm certainly not going to be using this method as my preferred setting, but it makes me wonder whether it might be an advantage on areas that people are having to run high smoothing on, so maybe someone who is having this difficulty might be able to try it out. BTW there is a picture of the nuggets for the day on my Facebook page at http://www.facebook.com/GoldCityDetecting?ref=hl Cheers.
  11. We'll i finally got to join the 1oz+ club!! My buddy Dave and i headed to Gold Basin for a half day trip. We hit our usualy spot and split up. I headed to a wash that i found a 5.4 gram piece a couple of weeks ago. I didnt hit the whole wash, so i figured id start where i left off. A bit later, i get a nice signal by a bush in the middle of the wash. It turned out to an 8 gram specie with some dark host rock mixed in. 10 feet away in the bank of the wash i get another screeming signal. This was the flat nugget, also about 8 g. I radioed Dave to tell him the good news. The next couple of hours there was nothing except a couple of meteors. I decided to hit the bottom end of that same wash on my way back to the truck. After a bit i get a nice signal in the wash, it was the .8g flat piece. The wash had widened out, and the bedrock was deeper, so i wasnt detecting to slow wgen i got a slight sound. I thought it was just ground noise because i was running the GPZ hot at 18 sensitivity and high yield and normal ground. I did a scrape and the sound was still there. I took about 6 inches off with the pick and the sound seemed more distinct. I fugured it wasnt mineralization but rather trash because the dirt was silt, not hard pack. I kep widening and deepening the hole and when i got to over a foot it was screeming. I was figuring tin can ir something. After about 6 more digs and around 2ft deep. I get it out of the hold. I did reach bedrock so i was feeling hopeful. It turned out to be a 1.41 (OZ) nugget and a pretty one at that, with a bit of quartz. I finally joined the club. I feel like i deserve a patch or something lol. I radioed Dave to tell him the good news, and he was eccited for me. (He was already a member pf the club) a bit under 2 oz for the day. I took Dave to the wash, with his big coil on the GPZ, to try to score him a big nugget, no luck. We packed up and headed home. oh and i finally paid for my GPZ in nuggets ...and some. thanks Chris
  12. 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
  13. Made it out for half a day yester to an old patch. My buddy dave let me borrow his big coil for the GPZ and i wanted to give it a shot. Good news, i scored 3 nuggets with it, bad newsI have a 9 in metal plate in my hip that sounds off every time i moved the coil to my right. Almost impossible to hold the coil far enough away to avoid the signal. Put heavy strain on my back trying to do that. So I switched coils and tried bumping up the sensitivity to 18 ground normal. I managed to get a couple more pieces. 4.6 gram total. Big was 2.2. I had found out my girlfriends brother is a closet prospector lol. He watches all thr shows but has never found any color. So i lent him my GMT and taught him my dig, rake, detect technique and he got 7 pieces for about a gram and a half. We werent getting cell service where we were and he didn't want his wife to worry, so we packed in early at 1:30. I text my girlfriend we were on our way. She asked why so early, and i told her Jason got sick. She text back with concern asking if was the heat? I replied "hes got a bad case of gold fever" lol in which she replied that i am a dork. I guess i am. Chris
  14. 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.
  15. Hi guys, looking for some advice. I have been lucky to have a 3km river section in north queensland mostly to myself for the last 6months...it takes an 90mins to walk in one way...so the few ounces have been well earned! A couple of small patches off to the side of the creek, the rest has been bits from the shallow creek bed. All pieces with my gpz 14 inch combo. I run it in normal high yield until the constant hot rocks slow me down too much and then its high yield difficult. Average depth would be 4-5 inches. deepest 9-10inches. Most common size has been 0.4 - 1.5 grams (with a few under 5gms) and i have dug NO deep holes for gold - very little trash in this area and deepest hole was for an old pick head. Question is, with the gold getting harder to find, would you recommend i try a 19inch coil over the same ground even though up till now there has been NO deep targets??? I heard you can run the 19 in normal a little easier than with the 14inch but i imagine hot rocks will still sound off and i cannot tell the different yet with a couple hundred hours on the machine! Thoughts appreciated. (ps a gpx with evo 14x9 has been over the patches too). stru
  16. 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
  17. Check out this week's Treasure Talk as Nenad Lonic details everything you need to know about owning and operating the Minelab GPZ 7000 19 coil. He covers ergonomics, swing techniques, field settings and managing different soil types. http://www.minelab.com/go-minelabbing/treasure-talk/in-the-field-with-the-gpz-19-coil
  18. opinions welcome regarding the "best" coil-cover for the 19 inch. I don't like the stock cover-but, that was a forgone conclusion.. I am not sure of the choices or durability of the manufactured items... I think the lexan is durable but...................more weight on a heavy coil. I will say that using the 19 inch makes the 14 seem a featherweight...in comparison. fred
  19. While up in the Sierra for a WSPA Outing I used my gpz. I had not used it since I did the upgrade. When I pushed the map button the man-icon came up but there were no tracks. The unit would mark a point and display it but no tracks to see where I had wandered. I also noticed the unit would not return to correct threshold in a timely manner. Nor did the other functions always work correctly... two different issues I think. What say yea? fred
  20. Hi all, Got a new video up recently, but I say (old) as the footage was taken just before Christmas!
  21. I've had my Zed now for over 2 years and less than 3. It is still under warranty. About a year ago I notice the pixels on my screen had developed a line in the lower right corner. I called Minelab and my only option was to send back the entire package in the original box. I may have done this at the time but I would have to wait a couple of months to get it back as there were no replacements available. Soon after I called the pixel lines went away and I have been using it just fine. Recently the pixel line has come back with even more lines. It is just a little distracting especially based on what I paid for it! Last week I called Minelab and they said they had plenty of units available. Call them back with the serial number and they would send an RMA number for me. When I called back they asked me the problem and I told them. I was then told I don't need to send back everything. I could send them the screen portion of the detector only. They would then send me a replacement screen which also has other parts of the brains in it. I imagine there is a board in there with the video and other functions so that would be replaced also. I don't know what is in the lower part of the detector. Has anyone had this 'fix' done and what are your results? They told me the day they get my screen will be the day they send out the new one. Mitchel
  22. 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.
  23. Went out yesterday for a full day of detecting. Wanted to try the new semi auto ground balance. Went with pretty much basic default settings otherwise. I have to say I was quite pleased with it. I was in one of my beat to death patches. Lots of magnetic iron stones, hot rocks. It ran very smooth. It seemed I could separate the targets very distinctively. The small bits of wire were a raspy on the edges sound. The square nails were bangers. The non ferrous targets were about the same as the gold targets. Had one really weird target sound. I always dig those. But I usually dig everything 95% of the time. But the weird sound was gold. Not sure if my focus was just better yesterday or it was the new ground balance. But my instincts were pretty spot on, on what the target was going to be. But very pleased with the new update and settings. The take wasn't too spectacular, but I avoided the skunk in a hammered patch.
  24. 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. GPZ 7000 Firmware June 2017 (Second Update GPZ 7000 Firmware June 2017 (20170630).ml3 - Version Information will display 1.10.8-2052) (11.26 MB) GPZ 7000 Firmware October 2015 (First Update GPZ_7000_UPDATE_IMAGE_20151009.ml3 - Version Information will display 1.2.8-98) (9.69 MB) GPZ 7000 Firmware January 2015 (Original Release GPZ_7000_UPDATE_IMAGE_20150130.ml3 - Version Information will display 1.0.8-57) (10.63 MB)
  25. 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.
