Hey All - I can confirm we will definitely be making coils and release will be in first half of 2022.
Coiltek Quality - Fully Minelab Approved and no need to break a coil to make a coil.
We will be releasing more info on this in the coming months.
Stay safe everyone.
I was pretty excited about this one so I couldn't resist posting the video of it, it's a 12x6" prototype test coil being used on the GPX 6000 to find gold, it found 3 bits on it's first run. This was one of my favourite coils on the older model GPX and if I end up with the new GPX it will be a size I'd have to have. It's long sensitive nose was great getting up between the rocks I regularly hunt in. This is purely for information for those interested in following the progress of the coils.
These coils are not being sold by them yet, it's in a testing stage and they will require an adapter which involves removing a chip from the original coil.
You'll see in the photo the adapter inline on the coil cable which has the chip in it that was removed from the standard mono coil.
And the video
The 3 bits of gold found while testing it.
The one to the left was the one found in the video.
I haven't done a story on a gold find for a while, partly because once you find a patch with a bunch of nuggets everything else seems pretty insignificant, a couple of months ago I did just that, it's only my second patch but had quite a number of nuggets, I'd guess at least 40 (Correction: at least 80 nuggets) and over 30 grams in total. I lost count of both the nuggets and the grams we got out of it in the end. I did take a couple of videos on the first and second day of it, after that I stopped filming and just worried about detecting as filming videos is very time consuming and wastes valuable detecting time 🙂 That patch has been the highlight of my detecting time and hopefully I can find another in the future, I'll put links to the videos for anyone that wants to watch them and hasn't seen them already.
Now to the more recent adventure, one of the most common gold spots I've been to is being developed, very soon it will no longer exist, already a large area of it has disappeared over the past few months with more to go yet, seeing it's probably the closest gold spot to home and one I've found a reasonable amount of gold before so it will be missed greatly. It's obviously getting extremely hard to find gold there as it's not a huge area really and it's been done a lot over the years by a number of people being an obvious spot to look.
My focus on this day was to take advantage of how well the GPZ and Concentric coil handles EMI to hunt almost exclusive in and around the power lines where people including myself with previous setups were unable to really detect very well, especially with my GPX 4500, it was terrible near the power lines, and what inspired me to try out a QED which ended up working quite well under the power lines but just didn't have the power of the GPZ.
I didn't take all that many photos as my aim was to get some video, I always struggle to get gold finds on video as I just use my phone to film and I have to put it down to do the recovery 🙂 I have a GoPro but just haven't bothered to use it yet.
I went to some bedrock and worked my way up digging every signal and recording and deleting all the recordings as they were turning out to be shotgun pellets, this is entirely normal in this area as it has a big rabbit plague and shooters love spreading their pellets around all over the place for me to dig back up again.
Here is a video of the first gold find, a .109 of a gram nugget, I was pretty happy with that to start the day as often at this location I go home empty handed. I didn't get the entire thing on video and I had my detector in difficult from when I was messing around the other day doing some testing and didn't check my settings, I'd never normally use difficult in my soil as Normal works just fine. Fortunately it didn't prevent me finding the gold, or the numerous pellets before it
Once I'd finished that bedrock area I walked up under the power lines to detect hoping I'd find something others couldn't get, I took a little video there of how the detector was working under the lines, I really love how well the GPZ handles power lines seeing they're in many of my gold areas. You'll also notice at the end of the video the millions of bits of rabbit poo on the ground, this is the reason for the shotgun pellets everywhere.
You'll notice in the video I discover I'm in difficult and seem a bit surprised, this is when I worked out I may have wasted the past hour detecting in difficult and it went through my head now I'll have to go check that bedrock again 😛 I was quite happy at that point I took the video or I may not have noticed for the rest of the day.
I started detecting along under the power lines and ended up in a little area I don't think I've been into before, I'm terrible with directions and locations so it's quite possible I have been there before and don't remember it but it didn't look familiar, I was still recording every target dig to try get a gold find on video and managed to do it, I think this might be my first time ever getting one from start to finish on video, quite happy with that.
And a couple of photos of it.
And my lucky last nugget of the day if you could call it that was a 0.038 of a gram nugget, very shallow on some bedrock, it took me about 20 minutes to recover this one, but I only got a portion of it on video, I kept moving it around but couldn't pick it up, I had no idea where it was in the cleared area, I was wishing I had a VLF with me with tiny coil to narrow it down.
I'd imagine there are quite a lot of these little guys around it's just the amount of pellets you'd have to dig to find them would be crazy. I do it more for the challenge but the novelty wears off after digging a massive amount of pellets and not finding any nuggets and if you ignore the pellets you'll miss these little bits of gold.
So here are the 3 little bits for the day
and the weights
All a bit of good fun, I really enjoy chasing these little bits especially after the first one pops up to get you into gear looking for more. I can't compete with the photos lately out of Alaska for gold though, I'm just glad I can do the hobby near home and find a few bits to keep me happy.
Here is a little tour video of where I was detecting.
Keep in mind to run these coils you need to have an adapter and that involves cutting the end off your existing GPZ coil and making an adapter out of it, it should only ever be taken on by someone very skilled at electronics or really the best thing to do is get a professional to make the adapter for you to avoid any problems.
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.
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.
Part II: the adapter failure next.
By Steve Herschbach
I wanted to clarify this, in case people are thinking x coil is not welcome here, due to some x coil related members leaving the forum.
I support anyone or anything that legitimately extends our metal detecting capabilities. I applaud x coils efforts.
What I did not like was the fact that you have to take a perfectly good coil, and use it to create an adapter. The process is not simple, and if done incorrectly can fry a GPZ 7000. The repair will cost thousands of dollars, and that is not an exaggeration. Further, there appears to be nobody who will make these for people, and warranty that if the work blows up the detector, that they will insure those costs. In others words “do this at your own risk.” Seems simple to me. No drama, just “do this at your own risk.”
The knowledge of that risk was suppressed, and people who expressed concern were attacked and ridiculed. ANY mention of the risk was met with swift damage control that attempted to shout down the offending party.
THAT is what I objected to. I’m a pragmatic facts based guy. I could care less about the adapter. I do care that it is something that should be a disclaimer on any “oh these are the greatest thing since sliced bread” coming from parties who received many thousands of dollars in free product. And I mean seriously, who actually buys x coils? Because from this dumb Alaskans perspective, nearly everyone reporting on x coils is sporting free coils.
Are there people out there that have to buy your x coils? I’d like to know who those people are, and hear what they have to say. Even then, I’m surprised how little you can trust even reports from purchasers. I was under the impression from several people that the QED was a pretty good product. Now, the ex-dealer is revealing that they are in fact a crap shoot, with very poor reliability, and poor physical construction. The truth now seems 100% the opposite of what I was being told by people, including people who berate others for concealing things. I gave QED quite a bit of positive coverage here that I now regret, because the so-called honest reporting of purchasing owners turns out to be quite suspect. When people buy junk, they prefer to quietly move it along with little fuss. In the meantime, the rest of us are not getting a clear picture of the truth.
The same thing was going on with the Impulse AQ testing. Parties experiencing issues are protective of the developers, kind of a Stockholm Syndrome thing, where you protect your abuser. Because, you know, maybe the next thing they do will be good, and would not want to get shut out of that! So relevant facts about issues that might be perceived as problematic are suppressed or hidden. I bailed out of the project over that.
Anyway, back to X Coil. I just want to let people know discussion of them is welcome. What is not welcome is berating people for being concerned over the adapter. That should simply be the default position for wise people. “Do this at your own risk.” Concerned care, not panic. Second, since free coils rained down like crazy, it would be nice if reporters clearly identify themselves as people getting free gear. I’m serious. I’m truly an outside observer to all this nonsense, and there appear to be almost no people who report on x coil, that do not have at least one free x coil.
So that’s my question. Is there anyone out there that is just a person that bought these, and made or paid someone to make an adapter? A straight up no question purchasing end user? If so, I’d sure like to hear from you!! If you have free coils, love to hear from you also, but please let us know the whole picture.
And to mention one last time. Never did, still do not have any issue with x coil discussion. It’s ok to great product, exploring new ideas, and I thank them for that. It was all the skullduggery and drama that bothered me. I’d welcome sane discussion of the product, and if they ever make a coil for a GPX 6000, I’d be interested.
