Hopefully with a little prodding from JP, Minelab will take another look at concentric coil options for their next GPZ incarnation.

Thank you JP for that very balanced report. 

Whatever Ilya and his team have done is certainly working. These coils have basically given the GPZ the super sensitivity of an SDC ( or dare I say it the GPX 6000 ) but with the raw power of ZVT !

Some of the little bits I have been getting at prodigious depths rechaining my old patches have left me scratching my head  !

Well, I got tired of waiting for ML to offer a smaller GPZ coil and ordered an X-coil. I've never done any electronics soldering before and followed Simon's and Rick's detailed instructions, along with Chet's new procedures to make a patch lead using my 19" GPZ coil. I ordered the required plugs and accessories for the project. Took my time, checked with my ohm meter as detailed in the instructions, secured with double-walled heat shrink and everything worked perfectly on my 15" x 10" coil and the GPZ 19" coil worked great....nothing trashed or disabled.

P.S. Latest on FB X-Coils page. WOW!

Even JP stated "Pretty impressive"! Rick Bryant using an X-coil 17" concentric. Some are saying the new concentrics will work as well as the new GPX 6000.

"Rechaining an old patch. Another 2.5 grams today in 8 pieces with the 17 CC, including another crumb that won't move the scales that read to 0.01 grams 😉 Clear signal at 1 inch in HY Normal and still there in Difficult. Gobsmacked at how good this coil is 😃"

What an interesting turn this discussion has taken. Some people might have been right all along then, when all this started. Me, I am just disappointed that no authorized and ML-endorsed procedure exists to have the plug made, by an authorized ML repair shop, including warranty. Sure, do it yourself obviously works for many and this is great for them. However, I am one of these guys who does not take any chance with a 10k investment but rather trust the engineers who built it the way it is. I am on the NF12 waiting list (will it ever come to the US?.....) and will get my 6000 any day now. I hope I won't have a huge disadvantage then, only because I am relying on products that are made by professionals without the need for helping out myself.

GC Aye I don`t think you`ll have a major disadvantage waiting for the 6000, but I suspect from your questioning you may be heading in the direction of early adopters and will evolve into helping your self out in the future, tis the spice of life.

You are right, Norvic. For some reason I just can't jump over my shadow just yet. But this could all change when I come into your neck of the woods 😁

I've just been informed that the 26" GPZ Concentric I ordered will now be a 30" The designers believe this will be the ultimate manifestation of the ZVT CC and it should have some serious depth. 

I replied that I will now have to grow a right arm like a lobster. Oh well! what the heck! 

Exciting times! Could be like the old "Bismarck" days all over again?

I have been using a 15 inch x coil for over a year in WA. I went back to all my old patches and was thrilled with the results. Not only could I hear new targets but they were often clear loud signals on area’s I gridded. I became aware of issues from a couple of prospectors in the Pilbara that blew their boards but so far so good for me. I would sometimes have issues were the machine would start generating false signals especially under trees and I would have to turn off the machine for a while. This sometimes helped and sometimes didn’t. Eventually I discovered that if I ran her on semi ground balance I no longer had any issues. I also use electrical tape on the patch lead connector to stop it from coming loose. This is my first post though I’ve been following for years, cheers

Question did they do their own patch leads? or get an experienced person to do the plug/socket/patch lead?

This thread tells about some of the early adopters and covers the 'period' when the prospectors you referenced  'blew their boards' so to speak.  They did try to make their own patch leads in the field and it is my understanding there was an error/short in a lead made by a tech in WA.  It is a bit of a blur to me now but I was following it at the time.

As a result of their problems and some of the other discussion about fine wires and temperatures I sought out a tech when I got my 15x10 X-coil.  I've used it without patch lead problems.  It didn't exactly make my old patches new again (probably more my fault) but I've found gold with it and I've not put the original or the 19" back on the Zed.

I've stated in other threads I backed over my Zed shaft with a 4Runner tire and broke the lower shaft but it didn't break the X-coil or affect the adapter.  My 19" then became a lower shaft donor as well as the chip donor.

      I have been itching to try the 10" X Coil out in Nevada salt for almost 2 years now, but life has always prevented me from making it to Nevada until now. And luckily, I also now have an 8" to try as well, plus a 15" and 17" concentric.
      Welcome to salt country! Sodium, even lithium salts here, all kinds. Salt everywhere, just ask Elon Musk!

      The 8" kills salt. I can't be more plain than that, it does great in places the stock coil is utterly unworkable. And it kills salt while retaining a good bit of sensitivity and depth too. The 10" definitely cuts salt down too, but the 8" takes it down another level again. Patches I had laboriously, slowly struggled to detect with the stock coil in bone dry dirt in July were almost silent with this 8", even though the soil was slightly damp past 2 or 3 inches in many places. 
      That said, what I'm discovering is something Steve has mentioned in the past - the gold out here in a lot of cases is simply just not very deep. This is largely due to soil deflation, or what is sometimes called lag deposits. It just means that the light dirt blows away or otherwise erodes away, leaving behind the heavies fairly close to the surface. You know how when you drywash you can lightly blow the blonde sands out from behind the riffles and expose gold and other heavies? Similar thing, except over and over and over for eons. 
      Anyways, my point is this: even though this 8" is an absolute pleasure to run in places that caused me a lot of frustration from salt response in the past, I managed to get most of the gold with the stock coil years back. I am finding a few dinks in each patch now, and it's because the gold just isn't there anymore. But this 8" is definitely the cheapest way to get 6000-like performance in salt for current GPZ owners, in my opinion. Actually, having run both machines, I believe this 8" may actually be more sensitive than the 11" mono on the 6000, but that just a guess since I didn't get a chance to compare them before the patch lead broke.
      The response on this coil is crisp and sharp. It goes from 0 to 60 on targets, often skipping all the steps in between, and it's a perfect compliment for running settings like I do with low threshold (around 13) and low smoothing.
      Here's 3 I got today at an old dink patch. The big flat one was 9" under a basketball size rock, which means the coil heard it from the edge. Which to me was impressive as hell at that depth. The tiny bit of iron was at 1" and a great target. It's literally verging on pen ball size, and that I'm slamming it with a GPZ is just kinda impressive to me. The 3 nuggets might weigh 0.3 grams combined.

      I had no illusion the concentrics would work any kind of magic in the salt, but this is simply the first time I've been able to get into the field to try them since they were sent to me, so I'm making the best of it. That said, I've run them enough now to say that I do feel they do slightly better in salt than the stock coil. I don't know if it has to do with the smaller TX or what. The improvement is slight though. What I can say is these concentrics are definitely a lot deeper than the stock coil. I pulled a 1 grammer up from what is easily my most gridded spot in NNV, and I know it had zero diggable or even questionable signals left in it. The nicest, most museum quality piece of gold I've ever found came from about 6 feet away so I had hopes, but this one turned out to be average. This crystalline gold is stealth gold, it's very hard to detect. It was a very obvious signal on the 15" concentric though.

      Unfortunately, the concentric doesn't only struggle in salt but it also struggles in bushy areas since the sensitive part of the coil is well inside the rim of the coil. So if you have areas that look like this:

      Then this is not the proper place for a concentric, even if you do a bit of weedwacking with the coil. So, I switched to the 8". However, what I wanted to mention is that the concentrics actually are sensitive enough on the edges to pinpoint with on the coil edge. It's not easy, and you really need to be close to the target, but it is doable, which surprised me.
      I wandered around the brush haphazardly and more or less randomly for a few more hours and got two more little crystalline pieces. Here they are all cleaned up, including the bigger piece I got with the concentric. A drastic difference between the flatter type gold, and you can see why it's harder to detect.
      Before cleaning:

      After cleaning:

      In summary: 8" is a great coil for NNV salt. And the concentric is definitely deep seeking, as AraratGold had posted in the past, I very much agree. But I'm unsure if the restricted sensitivity towards the outer edge which limits the coil's use in rocks and heavy bush cover will mean I end up going back to my 17" spiral, or if the depth gain makes these concentrics worth running outside of wide open fields. Since I'm getting a 6000 I probably won't be using the 8" as much, but the whole reason I'm keeping my 7000 is because I still see a use for these bigger X Coils and I believe these concentrics are going to do great next winter in AZ for me if I get them in the right terrain, and I definitely am not ready to lose the ability to run the 17" round spiral yet either, which I also didn't get to test against the 6000, but I definitely feel is outperforming the 17" elliptical on the 6000 at depth. But that's a 100% guess right now, and something I can test later.
      One thing to add on from my Arizona 8" post: this coil ran dead stable with zero knock sensitivity here in Nevada. There is something either with the ground or the vegetation causing this 8" to have knock sensitivity down there in Arizona, but not here in Nevada. It happened daily in AZ, it wasn't a mirage. It felt like the machine was trying hard to stay balanced, then when I'd knock it against a rock or just slightly rub against a branch it'd go crazy, then back to normal. I mean 80 or 90 times a day, not my imagination. I'd have to go out of my way detecting not to touch anything. But here in Nevada, not once did it happen with either my pre-repair or post-repair patch lead, and I could knock the coil against anything, no problem. So whatever is happening there in AZ has to be related to either the ground or vegetation. Most of the knock sensitivity was against vegetation, not rocks. It felt like the machine would go out of balance a bit when hitting the vegetation, but that doesn't make sense, and I'm really not sure what the deal was.

      Thanks to Davesgold and the X-Coil manufacturer, I got a gifted 17x12 Spiral Wound coil. The manufacturer took notice of my multitude of problems with the connector modification and sent me a new coil from Russia.  Bravo Zulu X-Coil for prospector support.  The weather has improved here in Sunny Yuma so I replaced the 17" round with the new coil and took it for a spin.  I balanced it over the ferrite with no problems and I experienced no bump sensitivity. 
      The first thing I noticed is how well the coil balances on my modified hip stick rig.  I do a lot of detecting in the walls of desert washes, putting the coil on its side.  The 7000 tends to get the "wee waas" if you don't keep them flat, but this coil seemed to really tone it down and it balanced really nice for less strain on my arm and shoulder.  On relatively flat ground I think I could swing this coil all day for less wear and tear on my 65 yr old frame.  I ultimately didn't find anything in the walls, but I hit some old hillside drywash tailings and popped these 3 nuggets.  All were at moderate depths but I was amazed at some of the deep iron bits I found.  Without some side by side target comparisons I can't say that my depth is improved, but I'm getting a lot better ground coverage and I can poke it in between rocks and obstructions.  Even if this coil is no better than the original Minelab 14", it's a lot more versatile.   This will be my go to coil from here on.  I'll stick the 17" round on over worked out patches, but this is my new secret weapon.
      Again, many thanks to Davesgold and X-Coil

      I got my GPZ back from Minelab last month, which included a new 14" coil and lower rod.  Only $3600.00 AUD lighter in my wallet.  As you may recall, I bricked the detector after the Patch Lead was defective.  It's still crazy hot here in Sunny Yuma, but I was bored and still curious about the X-Coil, so I shook off my concerns and cut the connector off my brand new coil and built the Patch Lead myself.  I was extra careful with the heat from the soldering iron and did a respectable job of putting together the connection.  I did a few practice runs on scrap wire and connectors so I was a little more confident of my skill. 
      I got out 5 mornings last week for a total of about 12 hrs run time.  At sunup the morning temps were still in the high 80's and jumping to 100 by 9:00am.  Unbearable in the desert washes with no breeze.  The one thing that saved me was the synthetic chamois cooling cloths, one around my neck and one under my cap hanging down my neck. 
      The first morning I did a complete set-up with the detector since it was, for all practical purposes, a brand new machine with all new printed circuits etc.  I waved the 17" X-Coil over the ferrite and got the machine nearly silent, though still reacting some to the ferrite.  I started in the area where I found the 28 gram rippa last May.  This area has a fairly hot layer of clay about 12" under the overburden.  Last May we were able to run this zone using HY, Normal, Sens 12,  (Threshold 27) with the Patch Search mode to quiet down the machine.  The 17" X-Coil in those same settings was way too sensitive, so I had to switch to Difficult to quiet it down.  Because I knew I could only be out for a couple hrs, I focused on trying to get that coil over gold hoping to then play with the settings.  No joy the first morning.
      The next morning I went out to an area that had produced half a dozen 1 grammers when the GPZ first came out.  I knew it was deeper and a little quieter ground.  We tried Paul's 19" GPZ here when it first came out to no avail.  This time I was able to zero out the Ferrite and switch back to Normal from the Difficult setting.  The machine was still a little twitchy so I backed off the Threshold to 22 and got it humming along nicely.  I gridded the area pretty good and came up with a few deep trash targets and then, right as it started to get unbearable hot, I got a faint, sweet rising tone. A lot of digging and sweating produced a sweet 4 grammer right on the hardpack, about 14 inches down.  Now a 4 grammer at 14 inches should be well within the range of the GPZ and standard 14" coil, but I've been over that zone at least 6 times over the past 3 years.  The only significant difference is the ground is bone dry this year.  Last year there were still pools of water from late season rains.  
      The next morning I was back to the area of the 28 grammer.  I found that the machine was more stable and I could run in Gen, Normal, Sens 14.  I got a couple deep trash targets and chased a number of hot ground seams and hot rocks.  The settings were really sensitive to hot ground, but in my mind that's the only way to find good missed targets.  Right at the end of the morning I got what sounded like another bit of hot ground.  I switched to High Yield from General and it brightened up the target, but still hadn't convinced me that it was gold.  The target was in the sidewall of a drywasher's hole, so the 17" coil was pretty awkward.  I dug out the ground so that I could get the coil level and the target brightened up a little more.  By then I had hit the hardpack which tends to hide these small, reddish hotrocks.  I dug dozens in this same area, but I needed to check this coil's capabilities.  The hardpack was brutal in the morning sun so I had to go back to the truck and get my handy Aussie (DavesGold) made pick.  I'm not going out without it now.  About 8 inches into the hardpack out popped a nice 1.5 grammer.  I can guarantee I  stuck the GPZ standard coil in the hole a half a dozen times over the past 2 years.  
      Thur morning I got out in the same area.  I chose a wash that a produced 5 small nuggets, in the sub-sub gram range, in May.  I concentrated on the deepest gravels thinking deeper nuggets must be in there, just beyond the reach of the 14" coil.  I gridded the zone where a bench had formed on the inside bend of the wash.  I went at it from every angle and was about to surrender to the heat when I got the faintest of faint tones.  Again I switched to High Yield and it brightened up some.  I switched to Difficult, nothing.  I started pulling down the bank so that I could get a good level swing with the 17" coil.  Slightly improved tone, still unconvincing.  I pulled down another few inches and got a much improved tone.  I switched to Difficult and got a dull growl, more convincing yet.  After much digging into the hardpack out came a nice 1.8 grammer.   I even photographed the hole for this one.  The Aussie pick is 28" long.
      I'm really starting to like this coil.  It's light enough for all day use with the addition of my homemade hipstick.    I run the hipstick to the bottom of the frame in my lightweight framepack, which moves the weight to the back of the hipbelt and off my shoulder.  I'm also running the SteelPhase amp plugged directly into the GPZ, no wireless connection between.  As per some of JP's guidance, I'm running the GPZ volume at 2, adjusting loudness at the amp.  I'm running the Threshold between 20 and 22 depending on how twitchy the ground is.  For the most part I'm running General instead of High Yield trying to reach those deeper targets.   The first 2 targets were well within the reach of the standard 14" coil, but somehow I didn't find them over the past 2 years.   The last one, doubtful for the standard coil.  As the weather cools I'll start doing a quick change to the 14" coil over new targets for a comparison.   Right now, it's still to friggin hot to bother.

      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.

      Have the 10" x-coil sitting at home and now waiting on the 22"x 21" to arrive. Was wondering if others have purchased lower shafts for each of there x-coils or just use the original one and undo/fit the coils to that one? (haven't done the chip mod yet so haven't bothered fitting the 10" x-coil.)

      Hey Steve,
          You and I have known each other for a long time, even had some great times metal detecting together.  That being said, the X-coils at this point scare me off.  I had an opportunity a month or so ago to test several different sizes from someone that is affiliated with the manufacture.  I was a bit excited at first, then found out I would have to cut/modify an adapter/chip from another GPZ coil to use one of the X-coils.  
      To me, the trade off to damage or destroy a $600 - $1500 coil to just get an adapter to work on an X-coil is not my cup of tea.  I don't need a smaller coil that bad to do this.  That being said, other guys like to modify/fix/tinkle or whatever might enjoy this.  
      I find the GPZ 7000 stock coil plenty sensitive enough to find gold down to a grain in size.  However, a smaller coil like an 11" or so would be nice for tighter areas or areas with more vegetation.  
      We were kind of promised a smaller coil originally from Minelab and that never happened.  I think one more smaller coil from Minelab would have eliminated most of this stuff about smaller coils. 
      Keep in mind, at one point I sold more Coiltek searchcoils across the US than any other dealer.  I could probably sell a ton of the X-coils, but not at the cost of sacrificing a detectors warranty.  
      For the benefit of all GPZ owners, I hope someone like Coiltek, Nuggetfinder, Minelab, X-coils or whoever can find a better way to make a coil that will just plug right into the GPZ and work.  
      Just my thoughts,
      Rob Allison
