Interesting feedback. Even with a smaller coil wouldn’t a PI have less reactivity to hot rocks than a hot VLF?
 

P.S. Not a challenge to what you have seen. Just trying to understand theories. The only thing I can compare to here is the SDC.

Yes a PI will have less ground reaction, in the case of the 6000 it’s pushing the PI tech to crazy extremes (even crazier than Steves insane sensitivity settings 😝), because of this ‘pushing of the envelope’ there can be undesirable behaviours in certain conditions like a tendency to be more prone to EMI, Salt and Saturation signals.

My point was if the standard 11” coil is achieving such ridiculous amounts of sensitivity in a ‘pushed to the very limits’ detector then there might be an issue in pushing that even further by making a smaller/more sensitive coil. All conjecture on my part and not intended to burst anyone’s balloon.  Logically a super sensitive PI is still going to be a better option than a VLF assuming the gold present is conducive to PI.

I'm located in California, USA and would also like to see an elliptical coil with a width in the 5-6 inch range. That size would make scanning bedrock crevices and rocky areas much easier to accomplish.

I don't want a more sensitive coil than the 11in factory round, as it already finds tiny nuggets. I think a traditionally wound small coil could tame it some against really nasty ground, yet the small size help it still find gold the size the partially flat wound 11in round Minelab already cleans up on.  

The issue is when making a smaller coil they will inherently be more sensitive due to the smaller size (more winds of wire to get the inductance right), everything gets more cramped inside a smaller coils housing so things like the solder joints can become incredibly problematic along with the proximity of the coil lead itself (I’ve discussed the GPX6000’s ability to ‘see’ its own coil lead on another thread).

An elliptical shape can very quickly leave the developer will nil room to put anything. I’m not saying it can’t be done just that there is a high chance that such a small coil could be problematic with GeoSense. The good thing about this forum is one of the developers is actively participating on the forum and will see the comments here and take them on board, the more people who ask the more incentive there will be to invest time and energy into overcoming any pitfalls. Demand will always drive incentive to invest. I highly recommend my American prospecting mates to put their name to this thread and push hard for this to happen, this is your chance to finally get the coil you desire. 😊

I can definitely imagine the construction of a smaller coil while keeping within the confines of the GPX 6000's requirements and managing it's extreme sensitivity will be a challenge. 

I know fully flat wound coils for the older GPX detectors were a maximum of 8-9" along the smallest dimension, due to space issues.  I wouldn't be surprised if there are considerations in manufacturing smaller coils like these that also hold true for the 6000.

I just hope we don't get something like a "plain vanilla" 8 inch round as the smallest coil due to technology or economic constraints.  While still much more user friendly at 8in over the 11in round, I'd be a little bit disappointed if that's as small as it got, as my SDC already has a stock coil that size for small gold.  Sure, the 6000 will beat the SDC for depth, but in confined, cramped areas, depth isn't everything.

Small coil sizes, increased sensitivity, more reaction to ground etc etc, takes me back to the swing from low frequency VLFs to higher frequency of the GM2 and GB2 with their small ellipticals and their productive popular performance, to just yesterday the success of the smaller X coils on the Z, tis elementary Coiltek and ML a small elliptical mono for the 6K will sell like hot cakes not just in the US but OZ too. You ever detect in FNQ OZ grass up around your ears you`ll know where I`m coming from.😉

Size does matter.....😜 But aren't we at a better place already? I remember those days trying to poke that Z/14 inch stock coil into small crevices, desperately trying to unleash modern technology into areas where usually only small VLF coils would fit in. Now with the 6000 we already have three great coils and more are coming, hopefully including smaller ones for us California bedrock freaks. Yes, we are at a better place. 😁

The 6000 being able to use mono coils opens up a world of possibilities for coil options. 

Round, elliptical, semi-elliptical, spiral wound, bundle wound, stacked-spiral..... the options are endless. 

What I want in the arsenal is a bundle wound mono in between the 11" round and 17x13". Reason is they are both too sensitive in some areas, and I want something that's deeper than the 11", but also smoother running. I think a bundle wound coil would achieve this, and I wouldn't be fussed losing sensitivity to the stuff smaller than 0.1 of a gram. Detech have a 12.5" round size which is an excellent compromise size, and loved that on my 4500. A less sensitive coil also means I'd be able to use Normal in more places, especially when the ground dries out. Mineralised clay and charcoal don't like being wet!

As an example of supply and demand though I can actually have a pretty good guess at the numbers of the new NF Zsearch coils that have gone out and as it currently stands I’d say my business here in Clermont has shifted an equal amount of Zsearch 12 coils as the whole of the US orders. Now to be fair the US winter gold season is only just starting up and the Zsearch was hard to get hold of at the end of the US season earlier this year along with the subsequent release of the GPX 6000 (plus the Zsearch is also an expensive add on), but this example probably goes a long way to explain why the need in the US has never been fully addressed which is a shame. 😔 

That and the Z search is only slightly different in terms of size than the original stock coil. Nugget Finder was not targeting the US market with this coil and my feeling is that anyone that bought it here in the US did so out of desperation for something different for the Z...they say it performs better then the stock coil so maybe that was enough justification to purchase...I'm still waiting patiently for a better coil selection for the Z (Coiltek you listening?) but have the 6K to play with till then...may have to go Russian eventually...

I would expect that Coiltek will be testing a range of coils to suit the 6k. The 14x9 would be my guess for the first release as they have the tooling and equipment already in place for that specific size.

Aye GC we sure are in a better place with the 6K in regards to coils, I love the 17 tis lightweight for its size and being eliptical is suitable to push through that grass.

Looking forward to the annual property owner burns to put it over some deep country the Z w/. 19 and X17CC coils scored on, see if it can sniff out a few deepies.

Hey Guys/Gals,

   I'm sure the 14x9 will be one of the first aftermarket coils from Coiltek for the GPX 6000.  It has always been a long time favorite coil for all detecting needs.  A smaller coil will also be nice, as there are goldfields with tons of brush, boulders and such that don't even allow a 11" round coil to hunt the majority of the ground. 

Steve - There is a smaller NF coil, the Z Search 12" Round for the GPZ 7000.  I have been using this coil since the release and I really like it.  They are back in stock again, plus they now have heavy duty skid plates for them.  

I have never tried a X coil to date on any Minelab PI or GPZ. 

Rob

      Seeing how this topic has numerous mentions across the internet, what are the range of faults exhibited? My nearest dealer is over an hour from me so I don't want to travel back and forth after picking mine up if I get a faulty one. So I know what to look for after collection and field test. 
    • By oldcoinhunter
      My first 6000 was faulty out of the box which they replaced with a new one. I've had the new one for 21 days and probably used it 8 days before it went bad.  When i was boxing it up to ship back i heard something rattling inside of it, not good. In researching i found that they've known them to have major issues since March or April, yet they have refused to address the issue with a production stop or at least look at the different production runs and recall those units. I think when it's all said and done there will be a substantial number of them that are faulty worldwide. As it stands now, Detector Center states that there is a" temporary" 10- 14 day time frame for repairing them. My bet is that it's not going to be temporary. If this failure rate continues there may be grounds for a worldwide class action lawsuit, who knows. Oh, and i owned a business for 40 years. Not a very smart way to run a business. JMO.

      Well my staff/I just finished the season and wrap up of field training for 2021 and our customers...and boy did it go out with a bang and big belly's thanks to Chef Rusty Bucket.  Smoked ribs, Bourbon shrimp in garlic sauce, berry pie and ice cream, smoked Brisket, bacon wrapped stuffed jalapenos and more.  Wish I would have taken more pics of the food.  As I have said before, the food/drinks/people are part of why I enjoy these trips, as I know the gold will eventually come.
      As many know, Gerry’s Detectors has been training out there at the burn barrel with a few different staff members since the 90’s.   We have been using just about every model of gold detector from the top manufactures as well as coils to see what the best results are.  The comparisons of customers detectors continue to see the improvements of technologies and capabilities which is what we want.  Yes there are times a more expensive detector may not produce the best signal response on that particular targets, but it’s what it is and part of learning.
      Some of what we found most amazing and it’s exactly what I expected would happen during the training at RP.  The gold nuggets being found during the 3 days of class was the most of any session in at least 5+ yrs.  More people went home with actual Rye Patch gold than what my staff/I have witnessed in quite a long time.  The knowledge shared was the same stuff we always go over, but the knowledge retained was higher.  The class size is usually around the same, but the amount of golden smiles of success was better than many yrs prior.  We know the VLF detectors when fit with small coils are going to find a few pickers, but to see the bigger PI machines perform so well and produce such higher %’s of beautiful NV gold was most impressive.
      So lets go over it again to see what my Staff/I observed, in no particular order.  Knowledge of customers detectors was actually retained, smiles of happy customers making the right choice of detectors, the amount of successful customers who went home with gold and the overall numbers of gold nuggets dug by the students.  There is one thing that I corollate all these positives and it’s the new GPX-6000, period.
      Yes we had SDC-2300’s, GPZ-7000, GPX-5000’s and the usual VLF’s in the class being learned by the students and those who were there with the GPX-6000 had the most Success.  But the success of gold nugget finds was just part of the fun.  Ease of operation and simplicity we’ve never seen from a PI Minelab was also most impressive.  The customers were actually not afraid of their detectors.  They didn’t worry if the timing and or sequence of adjustments was correct, as the GPX-6000 is pretty much a turn on and go.  The old way, a big multi page instruction manual (is missing) and now we get a 3 step Quick Start…and it’s true.  1) Turn On.  2) Raise/Lower Coil for 10s, 3) Begin Detecting.  Are you kidding me, no way that can’t be true.  We just paid $6000 for one of the latest technology fine tuned gold detectors in the world and all we get in the box to help learn, is 3 short steps with a combined total of 10 words?  
       
      Well folks,  it’s all true and so is the amount of happy customers who invested in our training and the new GPX-6000.
      If anyone thinks there was some other reason for the above, please chime in as all indicators are bulls eyed at the GPX-6000.  Overall the trip went exceptionally well consider the 100 yr rain storm that came through while we were down there.  I still love the natural beauty of Northern NV in the fall and the colors on the gold nuggets we dug.
      Hopefully the Spring/Summer class will be just as productive with a group of new enthusiastic customers and more gold being unearthed.

      Hello All,
          The new Minelab 17" Elliptical Searchcoils for the Minelab GPX 6000 have been flying off the shelves, definitely high demand.   Due to the high demand, I haven't had much time to use one, everyone ends of taking mine ... LOL
      I haven't seen much larger gold being found at depth yet, but I'm sure it is.  Curious how people and past customers are doing with this new 17" Searchcoil beyond covering more ground quicker?  
      We still have a few left in stock from the last large shipment and more on the way if anyone is still searching for a new "Christmas present.!"  Hahaha 
      Would love to see some pictures or at least hear about any success with the new searchcoil.  
      Wishing you all much success on the goldfield.
      Rob

      Each time I try and ground balance my 6000 there is no detectable change. While holding the GB button I pump the coil then move it side to side. It’s like it don’t work. I friend of mine says his does not either. What am I missing? I run in manual mode with the threshold on. The noise cancel works very well.

      This is from Steve’s GPX 6000 accessories page. 
       
      The following items do not come with the GPX 6000, but are likely to work with it based on what is known so far. This is preliminary guesswork, and it is not advised a purchase be made based solely on the information presented here.
