GPZ Aftermarket Coils

Recommended Posts

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.

      I always wondered if there was even gold around where the X-coil manufacturer lives, I didn't know much about Russian gold or if Russia even had much gold.
      Here is a video broken into parts of the Russian manufacturer showing the different capabilities of the 17x12" X-Coil between the Standard GPZ14” Minelab coil being used near high voltage power lines in Russia.
      It's good to see he is a prospector.
      Sorry about the quality of some of the parts. 
      It's a deep hole he has to dig to get it, nice soft soil though... that'd make life easier than using a jackhammer 🙂

      A lot  been said about these x coils when it comes to the zed...but in the beginning there was mention of new improved depth with x coils for the gpx users. As  a gpx user and I am probably speaking for many...any news on the performance and availability of these coils. I know I am not letting go of my 4500 anytime soon...

      Note from website admin/owner - this thread and related X Coil threads are for informational purposes only. This website and I personally do not recommend taking any actions that may damage a GPZ 7000 and cause considerable expense if done improperly or for any other reason. A blown GPZ board can cost thousands of dollars to repair and it will be on the owner for circumventing Minelabs protections put in place just to avoid such circumstances. I have nothing against any of these folks and am hosting this information in the spirit of doing just that - sharing information that may benefit some. There are significant risks however and I feel I am not remiss were I not to post this note  And so there you have it.
       
      The manufacture of the X-Coils has made a series of short videos of making a patch lead, I don't have much data for uploads, so it maybe sometime before that all get uploaded, there are some pictures as well.  There are no speaking words so no use turning up the sound.
      He has Rosin/Flux in the dish that he dips the wires into and then applies heat with the soldering iron to remove the red varnish and other oxides, and then applies some solder to each set of wires.
      Here is the first video.
      This shows the extra shield wire attached to the blue wire

      Small heat shrink tube placed over this instead of the cotton the hold into place

      Ready for some hot glue


      The finished patch lead, he wraps tape around for extra strength and stiffens up the patch lead

      The x-coils aren't water proof? Is that right?
      Was heading away for 4 days of nugget hunting in the caravan this week but it looks like it's going to rain??️
      Any thoughts on whether the rain may cause any problems to these coils?
      I know i used to detect in the poring rain with the coiltek elites and the 11" and 18" were fine but my 14" used to false when pressed against the ground. This only ever happened when it rained and i think moisture was getting in where the cable entered the coil.. I was thinking maybe taping some plastic over where the cable inters the coil on the x-coils just to be safe. 
      Any other time id just cancel and go the following week but this is the last opportunity according to my wife to go for sometime. (new puppy that will need toilet training etc)
       Im keen to try out the new x-coils and hit a spot that may soon be exempt from prospecting in a few months time.

      Saturday morning Mrs JW & I packed up the caravan & headed off to goldfields afar. Having got the caravan all set up & sorted we headed off to see the farmer to let him know we were about for the weekend. I hadn't been over this way for a while so it was good to have a catch up with him. Where I wanted to go to try the X coils he told me that they had done a poisoned carrot drop by helicopter for rabbit control & it might pay to keep away from that area. Bugger. So we did. Which left me to go where I had already been over a few times with the X coils & that area had now dried up for me. I did try again but no joy. Other areas I went over I got sick of digging shotgun pellets. Bloody rabbits. I tried one more area before dark & managed one small bit. I didn't even get a picture of it as I had left the phone in the wagon & couldn't be bothered going back for it. It was one of those imagined type signals but there was something about the first little hint of 'was that a signal'? Not always being there I questioned it. But you know how sometimes you think you heard something very slightly that sounded a bit different to a bloody shotgun pellet. Even after a few scapes it still wasn't always there but I was sure I had heard something. I laid into the dig a bit more & then the signal came to life & it was a small bit of gold down in the schist bedrock. That was it though.
      Next day we woke to an awesome sunrise.

      Went up to investigate the area I wanted to get into. Damn....there was a helicopter loading up with more carrots out in the paddock. Bugger. So we went for a bit of a drive & on heading back past where the helicopter had been filling up we saw the helicopter flying off into the distance & obviously heading off. So I decided to go into an old turned over gully further down from where the helicopter activity had been. It was a gully that had dried up on the gold take for me with the Zed & ML 14" coil. On driving over the paddocks the carrot drop was obvious. So to were the bloody rabbits. On getting to the gully the carrots were not as prolific. But during the course of the day detecting I could see that the rabbits had had a good go at the carrots & there was just small shredded remains here & there of carrots.
      On the detecting side of things I was again getting my share of bloody pellets. Bugger. The 10" X coil loves these damn things. I was in High Yield/Normal & full max sensitivity. I was loathed to turning down the sensitivity so put up with the pellets & worked on the scrape it once & if it moves ignore it & move on theory. It still plays on my mind that any one of those could still be a bit of gold. But I cant keep digging pellets all day. So was going for the deeper signals that lived on past the first scrape.
      One such signal finally came from an old timers throw out pile. Note the rabbit holes...EVERY WHERE

      Mrs JW sitting up in the wagon. The grass was still a problem in the old workings. I have been hugely spoiled in the past & had the pleasure of detecting in here many times with no grass at all. Even with the Zed & ML 14" coil which did get me a few bits & pieces.

      Gold it was, small but.

      Then further down the same throw out pile.

      Note the carrot. And not a Garrett Carrot.?

      Another tiny bit of gold. Smaller than a pellet.

      I stuck to detecting close to the gully bottom they had dug out as there was a bit of bedrock showing. Hard to see in the photo but under the detector is the bed rock & I got a faint signal to the edge of the bedrock. On digging down the signal improved & was coming from a drop off point of that bedrock.

      At the low point I was into rotten crumbly schist. Signal booming I was 100% sure this was going to be gold.

      It was but it didn't live up to how loud the signal was & I was expecting bigger. Look at the depth though for that small bit of gold.

      I took this next photo as I guessed it was about the same spot as the photo of me with the brush cutter which was about 4 years ago when I cut out a heap of wilding thyme bushes.

      Looks like they haven't grown back....yet

      Not far from that last piece another signal down in the rotten schist bedrock. Note all the rabbit poo.

      Small gold again

      Just kept on coming

       

      Another almost imagined signal that had me investigate. Livened up at a bit of depth & down into the rotten schist bedrock.

       

      You can see the beauty of the smaller coil for getting in among those thyme bushes that ML 14" doesn't have a hope of doing. Note to up in the back ground how the wilding thyme bushes takes over valuable grazing land.

       

       

       

      A very thin flat flake

      Things then dried up for me & I went over to a couple of throw out piles that were away from this main run of workings & where I had snagged a few bits with the 3000 & the 4500 but nothing later with the Zed. They was no bedrock & the throw out piles where of clay & not down to the rotten schist. I wasn't liking my chances & decided that after going over these piles I would call it quits.
      I got a nice signal that lived down past the first couple of scrapes.

      Wasn't holding my breath as the soil was still pretty loamy but just getting into a bit of a colour change when the signal had moved.
      Ha...well I'll be buggered.

      Biggest bit of the day. I then got on to a bit of a roll.

      That nice colour change again. Rusty clay material.

      Out popped this small bit.

      And another from the same dig on checking my scrape out pile before back filling.

      Right beside a rabbit burrow I got a signal that lived on down quite deep.

      My final sassy bit for the day before calling it quits.

      All up 16 pieces

      For just under 1.5 grams

      Loving this coil.
      Best of luck out there

      Hi guys, Last Sunday Simon & I headed back to the area where we were at a month ago where I had a some success with the Zed & X coil 10 x 9

      We just carried on from where we left off last time all be it over ground I have hammered over the years & even with Simon we have been over it numerous times. Simon with different detectors & me with the Zed & ML 14" coil but not the X coils this far over. Simon was back on his 4500 & NF Evo coil but he knocked his sensitivity down to 13 to try to eliminate getting so many shot gun pellets. Seemed to work well for him, so on this rare occasion I got more than him.
      My first signal wasn't too long in coming. I was targeting the cracks & drop off shelf areas where there is usually a crack that gold could have dropped into. First signal was at the base of just such a little ledge drop off & schist fracture in the bed rock. note the grass growth. This isn't usually like this but I don't think the sheep are are allowed to graze in here any more. I said to Simon that if this is the case then detecting in here will get impossible as the grass really takes hold & makes it impossible to get the coil on to the ground & of course the grass loves the cracks & crevices where the roots can take hold in the deeper ground. 

      The signal had moved & was in that crack.

      Small though.

      But no catch & release.
      Carried on & a 2nd signal came in exactly the same type situation. A little schist drop off ledge.

      I actually wish I took a picture from when I first got the signal before disturbing the ground. So you could have worked out the depth. But I scraped away the dirt until I was down to the lower ledge of the schist bedrock before taking a picture. You can see where the height of the dirt was. Virtually right up to the top of that bedrock where the moss & lichen is growing. Note too the little crevice coming to light. The signal was booming but still down in that crack. 

      I had the pointy end of the pick as far as it would get into that crack & the signal was still down in there. I just knew it was going to be gold.

      I looked around for a long thin stick but no joy there. In a last ditch effort I positioned the pick with the handle 90 degrees to that rock face, which gave me the narrowest part of the pick to drag sideways along the crack to try to move the target. It wasn't easy but I finally managed to move it & get it out. 

      It made me work for it but bingo. Out it was.

      I could have sworn for the depth of the original signal that it was going to be bigger than that.
      Again on the edge of a schist drop off I got another signal. Note how the grass favors those schist crevice areas of deeper ground.

      Again in the corner edge at the bottom of that drop off.

      Another sassy bit of gold.

      No record breakers.
      I then hit a shot gun pellet grave yard which was driving me nuts. Pellet after damn pellet. One scrape & they had moved. I should have known better than to persevere with those type signals. Another signal, one scrape & it had moved.

      I hesitated about retrieving this one, but I did.  And was rewarded for doing so.

      Smaller than a pellet even.
      At this point Simon came up to have a look & to swap over to his Nox 800. He lasted about 10 minutes with that as the pellets drove him crazy. He went back to the 4500 & manged to snag a bit of gold. I wandered away & had a bit of a dry spell. I was hoping for another piece before I stopped for a coffee break & a bite to eat. It took a while to come & we were having the old sleety/rain showers coming through. When I got a nice little signal.
      It was down a wee bit & ended up being in a little hollow in the schist bed rock. It didn't take long for the little hollow to fill with water as it was in a natural small gutter run off. Hence why I detected down this little depression in the ground. 

      Small bit of gold it was. Well...not the smallest of the day.

      I then stopped for my well earned coffee. While having my coffee I checked my phone, which was very iffy with its signal. Blow me down, a message from Steve H. So I gave a quick reply stating what Simon & I were up to. I had 5 bits at this stage & Simon one. Simon at this point wandered up for a coffee & a bite to eat as well. After our break I headed down to where Simon had started detecting. I saw a lot of over turned rocks & slabs of schist. Just below one of his area I got a good little signal.

      You will notice up the right edge of the photo turned over slabs of schist from Simon. I was detecting those two cracks you can see with the grass growing in them. No surprise to me that I got a signal at the start of that one where the detector is.
      It wasn't a bad piece either. My biggest for the day.

      Simon saw me taking photos & asked if I got one there. I replied that I had & he came down to see if it was an area he had been over & hadn't got. I think he was satisfied he hadn't detected that spot. My reply was, Why not? Considering those cracks were right there. Any way. That was the last one for along spell. I did get one more but no pic of that. We called it quits as we had a bit of a walk to get back to Simon's vehicle. Due to the damp conditions, Simon's vehicle wasnt ideal to have brought in here. We had to park up further back from where we would normally. The wet conditions had made the glacial silt like grease & we had actually pushed his vehicles limits getting to where we did. Despite being 4 wheel drive his tires weren't up to it. On the way out we slipped of the track into the gutter. with me pushing we managed to get back on the track & it was a very slow slippery drive back to the main road & getting dark. We made it. Whew.....
      So all up for the Zed & X coil 10 x 9 was 7 little bits for not even one gram.

      This is my total of all detected gold from this area over the years. Just over two ounces & hundreds if not thousands of little pieces. The bigger bits seemed to have swum to the top.

      My pellet total that I brought home. There were many that I threw away down into no mans land that would never see a detector.

      Cheers.
      Good luck out there
      JW ?
