Came across a post on Facebook, about this gentleman testing a few aftermarket coils. This really opened my eyes this morning. I was under the impression that the Minelab coils were chipped and no aftermarket coils could be used. If this was the case? Why did they wait so long? The smaller coil would suit my needs just perfectly.   http://golddetecting.forumotion.net/t26022-gpz-18-coil-test-report

It is with great interest that I have been following the development of these coils on the Australian 4umer forum.

Having had a good run with the GPZ7000, (found enough gold to pay for it in less than two weeks) I looked forward to the production of the 19" coil which promised much extra depth. (according to the advertising, one could expect at least 30% more than the standard 14" coil) After much delay, I was at my local ML dealer early on the day of release. When I picked up the box I wondered what else could be in there, as surely all that weight could not be just a coil. Wrong. Oh, well, never mind, if it gives me all that extra depth I can put up with the weight. The appalling design meant I had to make up a workable skid plate, as the one supplied had little rubber patches that gripped on any grass, and worked as a brake.

 After exhaustive testing I could not get the thing to perform any where near the claims of the manufacturer, and the settings suggested by ML's 'guru' were just unworkable in most Victorian ground. I did find gold with it, but there was little hope that it would "unlock all those big nuggets at greater depth".

I then made the mistake of posting my findings on the 4umer forum, and stated that the 19" coil was over weight, over rated and over priced. I called it 'The Dog'. (a name that stuck) Having once been a tester for ML, finding hundreds of ounces with some of their prototypes, I mistakenly believed that I had some sort of credibility. Wrong again. I was abused, denigrated, and accused of being a sour old 'has been'.

To compound the situation, I was involved in testing a new Australian built and designed detector, which then resulted in another Australian forum devoting eleven pages of some really disgusting and personal abuse. One member of management of 4umer then banned JR Beatty and myself from their forum for life. Reason given. Trouble making.

I now read with great amusement: "I and a lot of others got burnt by the ML 19" coil"  Slim Pickins - 4umer management.

Exonerated, after all this time?????

Reg, please leave the grievances you have with other individuals on other forums at the door when you enter. This forum exists in large part for people, you included, to get away from all that. So don’t bring it here. Thank you.

There has been a thread about these aftermarket coils ongoing since April on the Minelab Forum.

Steve, I merely made the point that honesty is not always the best policy if one wishes to avoid abuse, and we the prospecting public are sometimes just tools for profitability. To not speak out about products that are less than claimed only encourages companies to continue to take us for granted.

I wish the company producing these coils all the best, but regret that this advance has had to come from Europe and not Australia. From what I can gather both Coiltek and Nuggetfinder wanted to produce aftermarket coils for the 7000 but for whatever reason were unable to do so. This has been a less than desirable situation, as there has certainly been demand for such products. Healthy competition is always beneficial for us the consumers, but has been lacking in this area.

Perhaps that is the case elsewhere but not here. Anyone is welcome, in fact encouraged, to post honest reviews based on actual use. I have never deleted a negative review of any product as long as it is above board and avoids name calling and stays factual/dispassionate in nature. Anyone abusing other forum members may be banned without warning. I simply will not tolerate it.

All I ever ask is people realize opinions can vary as to product usefulness and applicability at locations around the world. Each persons experience applies to them alone and do not apply globally. My opinions apply to my uses at my locations for my purposes and your opinions are based on your locations for your purposes. Therefore opinions may differ and any wise person looks at a wide range of opinions instead of relying on any one source. Cross talk and weighing in on people personally is never called for. The bottom line is I am sorry other forums allow that kind of behavior but I do not. That includes dredging up grievances from other forums and bringing it here. I expect this to be the end of the discussion on that matter. Thank you.

This thread is about these aftermarket coils. Let’s stay on topic.

Yes it's me that posted up about the new aftermarket coil on facebook and have been helping Stan do some testing, this 1 coil is in Australia and, now another 2 have arrived so there is only 3 in total so it takes some time to make sure they will work well and hopefully give the GPZ7000 users some extra choices in a range of coils.

I mostly use the GPZ14" coil on my 7000 but I did run the 18" prototype coil on my 7000 for a week or so and found a bit over an oz of gold with it in total, and the biggest nugget I found with it was a 4.14 gram nugget at aprox 8" deep in extremely mineralized  ironstone ground in Western Australia, as this is where all the testing has been done in Australia so far.

I was very impressed with the prototype 18" coil, it weighs about the same as the 14"GPZ coil has great sensitivity and I found it in some ways similar to a mono coil around the outer edge and the extra coverage with the bigger coil compared to the standard 14"GPZ was also a bonus.  It was finding nuggets from 0.1g up to 4.14g and plenty of 0.5g and 1.0g sizes.

Stan found some quit large pieces in his 6 day detecting trip, which he has posted about on the other forum

It ran very similar on the same ground when compared to the standard 14"GPZ coil  

I am looking forward to testing the other size coils as well.

cheers dave

If this overseas company can do it why can't or wont Coiltek &/or Nuggetfinder, or even Minelab for that matter??

Good question JW, as far as I know Nuggetfinder did some work on this very thing and for whatever reason stopped, and the others, well Minelab could for sure if they wanted to, but no word if they are or have, so overseas entrepreneurs have taken up the challenge and have something that works, does it work better, well that's where/why a bit more testing is going to be happening with this latest batch of 4 coils.

      Just my 10 cents worth on after market coils. I know this thread was about the coils for the 2300 but someone mentioned the Russian coils for the Zed. I made a small mention last week about me taking delivery of three of their coils. The 10 x 9, 12" round spiral wound & the 15 X 14. Last weekend with Simon I got skunked with the 10 X 9. I had great intentions of trialing all three this weekend but got off to a good start with the 15 X 14 & just stuck with it. Actually it is my 2nd outing with the 15 X 14 & it is proving to me to be doing a very good job on ground I have pounded to death with the Zed & the minelab 14" coil that had stopped producing gold finds.
      I will do a more in depth post later but just to show you how well this 15 X 14 Russian X coil did for me on ground that was no longer coughing up gold with the ML 14" coil. The depth were staggering. I bang on about how blown away I still am after 2.5 years of swinging the Zed & the ML 14" coil but this 15 X 14 coil is  next level. It runs quite a bit more sensitive so I am putting up with a bit more ratyness.  I tried to stay in my usual settings of High Yield/Normal & sensitivity up at 18-19. We had quite a bit of heavy rain the other day which made for much easier digging but it livened up the ground a bit. So wasn't able to handle the ratyness all the time. I have got into a good understanding of my Zed running in these high end settings I am pretty good though at dealing with it but it can get fatiguing with all that commotion & reading & deciphering the signals in between it all. But it pays off.
      3.3 grams at a good 14 inches. My biggest for ages.

       

       

      Some of the small ones were at around 4-5 inches. & 2  were just .06 of a gram.

      So small for that big coil at that depth. I think so any way.

      Total of 12 for 5.5 grams

      I am loving this coil. It has changed the face of my detecting for me on old flogged Zed ground. Ye Ha. Bring it on.
      Good luck out there

      It is unusual for a WM 12 to take over 24 hours to recharge? That is what I have recently been seeing when I recharge it after being out for about 6 hours of detecting. Does that mean the batteries need replacing? If so, how is that done?
      I will also take a look at the 7000 threads, but I don't remember seeing anything on this.

      My second outing with the zed I tried the factory presets except I used semi-auto ground balance and ground smoothing off. Tried those settings on a patch I've pulled many different nuggets out of over the last year. (4.5 ounces) The zed didn't get any more targets using those settings. 
      I then proceeded to increase the sensitivity up a fair bit but still no luck. I tried many settings/timings but alas no more gold with the zed on this patch.
      As a last ditch resort to try and justify my purchase of the zed after a 3.5-year wait, I cranked the zed up to the most aggressive settings I could get away with hoping to find something that my 4500 had missed.  
      The settings were... Extra Deep, Normal, sensitivity 20, threshold pitch 33, Locate patch, audio smoothing high. (also used steelphase booster with filter 3 to quite it down even more) (ferrite balance etc) 
      I was pleasantly surprised at how well the zed handled the ground using these settings compared to the gpx when running flat out. Hardly any hot rocks compared to the gpx. Unfortunately after a day of trying this and many settings and thoroughly going over small patches of ground that the 4500 had success on the zed found nothing. My conclusion is one of three things.
      1. I don't know what I'm doing. Although surely it's pretty foolproof using the zed in factory settings with a controlled coil swing and the coil slightly off the ground. 
      or
      2. Hitting my patch over the last year with the 4500 in Normal and Sharp timings with gain at 15 has done the job. Id previously used enhance with a high gain and done ok. But once i cranked it up in Normal there was still gold left that enhance couldn't hear. It makes me wonder if folk who say that they got gold in past patches with the zed ever bothered to max out the gpx on their patches first.
      or
      3. The gold was fairly shallow (350mm was the deepest bit found) and all within the range of the gpx so no chance for the zed to prove its worth.
      I was a little disappointed with the zed if I am honest but will give it time and look forward to seeing some kind of advantage over the 4500 that I hear about from others who have had 4500/5000 and now swing the 7000. The thing that I didn't like is that it's advised to keep the coil slightly off the ground. I'm a scrubber and like to use the coiltek Elites to push branches/leaves out of the way in an attempt to get right up close to the ground. Sort of defeats the purpose if you ask me to be swinging 3cm off the ground.

      My Z’s GPS will not connect to the satellites.  I have left this on for days now for it to connect and did a factory reset and left in for a day. No luck.  Anyone else have this problem and maybe a solution.  Probably gonna be calling Minelab but my warrenty is just out of date.
    • By Jin
      When you connect the zed up to install updated software does it tell you if you any updates have been previously installed? The machine I just brought has only been used a few times (3 years old) The chap I bought it off didn't know much about prospecting so I'm presuming no updates have been done.

      We've all had our 7000s for a few years now.  Much of the time we keep the same settings.  I'm going back to areas where I've used my 7000 and other detectors and not finding the small gold or the deep gold that I see some of my friends finding.  I haven't asked them recently about all of their settings.  I'll ask the general question now.  There is no RIGHT answer.  Maybe we all can learn something that will let us find a few more nuggets in our worked out patches.
      During my most recent gold trip I set up my 7000 like this:
      HY, Normal, Sen 8-14, Volume 8, TH 26, TH Pitch 53, Volume Limit 13, Audio Smoothing varied, GB Manual, Ground Smoothing Off or Find Patch, BZ Booster
      Using these settings I've found 15-50g meteorites at 8 inches but no gold (maybe I didn't get over it).  Hot rocks were manageable and few.
