I was wondering if the aftermarket coils were that much better than the Minelab, i.e Coiltek.

I'm very hesitant to go Coiltek because the GPX was designed to use only Minelab coils?

My fear is i don't want to hurt my GPX 5000 in the long term by putting a coil on it that Minelab doesn't like?

It seems like everyone with a GPX is using a aftermarket coil. I especially like the Coiltek 9" Elite

I'f you were me would you get a Coiltek coil?

Coiltek and Nuggetfinder have both been making compatible coils for Minelabs, a long time. That said you may have a warranty issue if you get a very rare defective coil...it does happen.

Minelab coils are often underrated...they are as good as any in my opinion....

I suggest you use the mono and dd coils that came with the detector, learn the machine, read the manual...

and then you too can buy 15 different coils...just teasing, I have been there

There is absolutely no reason not to use Coiltek or Nugget Finder coils on your GPX. In fact I would say limiting yourself to only Minelab coils would be avoiding some of the newest and best coils for the GPX. Minelab stopped making new Commander models years ago. Commander (Minelab) coils are generally underrated in my opinion also, but do not take advantage of some new innovations in coil design that have come about in the last few years. A lot of people think very highly of the Coiltek Elite coils.

Apparently, I am outdated...what are the Coils made by Minelab called? 

Phrunt, I never said it was likely. But non-stock coils on a machine with a warrenty can/do and will create problems-no matter how rare.

I realize there are many new coils available but I will maintain that no beginner needs to buy extra coils until they have learned their new machine.

However, if buying more coils is what he wants-buy, buy, buy...the dealers will love it. They certainly got plenty of my money. And I found gold with every coil I ever bought. Did I need them, no...but, I did want them, so, I got them!

just my opinion

Minelab Commander Coils

Click the image below for larger view.

I really like the 15 x 12 Minelab coils but where you really do need to go aftermarket is the big coils. I would never swing an 18” Commander coil when I could be using a much lighter aftermarket coil. The Minelab coils are very good, but they are also heavy.

I generally agree with you though Fred. People go chasing off after coils way to soon in a lot of cases when simply mastering what they have would be more productive.

Thank you everyone :)

I will stick to the Minelab 8'inch for awhile. But i was also thinking of ordering a Coiltek Elite 9"inch so i'll have it for the future just in case the coils become unavailable.

GPX failures due to coils are almost non-existent anyway. A coil may not perform well but it's not like a GPZ where things actually fry. The SD/GP/GPX is very forgiving in that regard, which is why there is close to 200 coils been made for them over the years.

No worries Simon 

like the geography and astronomy I learned, my information is outdated..

As an example,.2010 on tour with Mark Hyde a customer had a detector go bad. Then another went bad, these were not stock coils. He wanted to use his coils but Marks machine. Mark would not let him use that coil again...

so, like great white attacks it can happen. Also, when you send the machine in they generally want the coil too...

 I have never had problems with NF, or Coiltek

Don't beat yourself up, Fred.  I am (or at least 'was') a professional astrophysicist and frequenty find my knowledge has been superceded with recent discoveries.  That's a good thing for the field so I consider it a win-win when I find out my (old) ideas need correction.  It sometimes seems civilization is going backwards, but when it comes to real science (not pseudo-science nor "fake news", real, perceived, or smokescreened) we are always gaining as long as we keep things in perspective, with humility, and with an open mind.

      Based on Jasong's report that a GPX 6000 was on display in Quartzsite, Beatup and I drove up there this morning from sunny Yuma.  We did indeed see and touch the machine.  There will apparently be other opportunities in the near future including the Quartzite gold show in Feb.  Everything is up in the air, so don't count on anything I say as gospel as far as a schedule.  Nothing is firm, make your own plans accordingly.  The US release is still uncertain but it was suggested perhaps late spring or early summer.  I think mid Feb might be overly optimistic.  
      However; we saw and ran the machine albeit in the gravel parking lot of the RV show.  Only the DD coil could be run because of the EMI.  As of now, the US sales will include the DD coil and an 11" mono coil.  There will be a 17" Mono available as an accessory for the machine, but it's US availability upon release of the machine is still in question.  The African market has a corner on the market at this point.
      My observations are this:  As stated elsewhere, the machine is an ergonomic dream.  Well balanced when fully extended with really nice carbon fiber shafts.  The battery pack is detachable and has heavy duty rubber coating on the bottom to absorb shock plus the machine balances perfectly upright when setting it down to dig.  The Minelab spiel is no different than the star chart shown previously, so I can't really comment on the accuracy of those claims.   
      We ran the machine in the DD mode to eliminate EMI.  We detected  .1 and a .2 gram nuggets in the parking lot at a height of about 4 inches.  All of that is meaningless as far as it's actual performance in real world conditions, especially as it pertains to the Mono coil.  This sneak preview was never intended as actual testing and it started raining while we were there.
      From my perspective, I would seriously consider a trade down from the GPZ7000 purely from the ergonomics and portability.  I would hesitate if the 17" Mono was not immediately available.   I'll hit 67 yrs old this summer and just don't get up and down the rough terrain as well, especially with the weight and balance of the GPZ hanging off my shoulder.  
      That's about all I can tell you from a 30 minute preview in a gravel parking lot.

      I've been a successful business person in my life, and so the business aspects of metal detecting are something I follow more than most. It's an interesting industry to watch as it is fairly small, and I know a lot of the players.
      Lots of people have various issues with Minelab and some of the things they do. Yet one thing should be obvious. When it comes to genuinely extending the technology, Minelab tends to be the only game in town now, while others try to keep up. A big problem with U.S. companies is they got into this 10 year product cycle, while Minelab sticks more to a two year cycle. So where a U.S. company will have one machine for ages, Minelab will crank out multiple generations. People denigrate this as drip feed, but the advances are genuine, and after so many cycles Minelab is only extending the lead. They patent prolifically also, which helps build a wall around the lead they have.
      This success leads to a huge cash flow, that can be used to advance both the technology, but also the actual design complexity and sophistication, which is reaching levels where I can't see how some of these other companies are going to be able to hang in there. The competition should be grateful for the high prices on most Minelabs, as it gives them space to compete. Witness what happens if Minelab decides to drop a tech bombshell at a lower price into a mature market just to disrupt it, as has occurred with Equinox.
      The CTX 3030 I think does a good job of showing off Minelab design prowess. Nothing is perfect, but that is one sophisticated metal detector, both in function and physical design.
      Then I saw this on the GPX 6000 Reveal thread (thanks to VicR):
      Link to Australian design patents for the GPX6000 with the tech drawings just released. Looks like there are two design patents for the 6000 - 202014625 and 202013037

      I don't know about you guys, but what I am seeing is levels of sophistication beyond what we normally think of when we think of metal detectors. geoff_junk added the names of the designers. Cosmo Luppino, Dominic Paul Gralton, and Simon Hill. I do not know who these blokes are, but I suspect these are names that should be known because of what they are contributing. Long story short, there may be issues, but thank you Minelab for doing what you do. Imagine if the company did not exist what the available options would be, and I am sure a lot of people would agree.

      There is a Minelab rep from Chicago in Quartzsite right now with a GPX 6000 exhibiting it. Tomorrow is the last day, I can't make it down there though soon enough to see it. Anyone else in the area and curious to see might go to the Miner's Depot booth at the RV show though.

      My second hunt this past week was at my favorite EMI beach. Besides getting a new scoop I also decided to try a Coiltek 14" anti-interference coil for my GPX. I need every advantage when hunting this beach, so I decided to give it a go. I was hoping I could still use the coin/relic setting with this coil as it is the deepest, but it was not going to happen. So I changed timings and it worked well. Now all that was left was to see how much depth I lost. Honestly, at first I did not like the coil since I really wanted the most depth I could get, as the coins tend to be deep. But I kept at it and eventually did get 2 silvers that were around 12" deep. Not bad, but a bit short of the depth I wanted. Then something strange happened. I got another deep sounding signal and dug down around 12". Still no target with the pinpointer, so I scraped another 2 inches out, and finally I heard the target, I carefully removed 1 more inch and I flipped out a small copper ring. I measured the hole and it was 15". I couldn't believe I heard that ring that deep. I'm pretty careful with my measuring and I saw the ring flip over when I was pulling sand away, so I'm confident that it was not falling back into the hole. I use a spade to get the bulk of the sand away and then use my hand to finish finding the target. Although it's just a junk ring, I like the enamel design that the 40's through 50's era produces. I've found a couple religious medals before and they were enameled the same way. A couple more trinkets and lots of junk I didn't photograph, and that was it. I'm always happy to get any silver at this beach, so 2 silvers this time of year is a good hunt for me. Just happy to get out twice in one week.

      Hello All,
         Had a great time testing the new Nugget Finder "Z Search" Searchcoil today on a wash I haven't hunted in some time.  This small coil for the GPZ 7000 is much lighter, more sensitive and easier to pinpoint small targets with.  I was super impressed with the new coil, wish I had a few dozen in stock.  I also love the fact you don't have to modify anything, just mount and plug in like a stock GPZ coil.  
      I have already had 3 customers burn up their $8000 GPZ 7000 by making some wiring mistakes on adapters for aftermarket coils.  In my opinion, I don't recommend anyone voiding a warranty or sacrificing a $8000 metal detector if you make a mistake.  
      Pictured below are nuggets found today with the new coil here in Arizona.  The coil comes with a lower shaft, mounting hardware and skidplate.
