GPX 6000 Rod Twisting - Owners Weigh In

Recommended Posts

The twisting of the shaft is annoying and I would consider an aftermarket correction.  I hope one eventually comes to the market.

On a side note, the 6000 light weight and technology rocks!

I wonder if tacky products, like this Golf Tac Grip Enhancer or Firm Grip might help.

Do not use any chemicals, just plain water is sufficient.

I had wondered these same things for the movement at both shaft and the rubber cover for the jack. A pine rosin certainly would introduce a tackiness that could reduce the movement. However, I’m uncertain what effect it would have on the polymers since rosin is used as a plasticizer, as well. Anyone brave enough to be the test subject? 😅

Well, I’m half way there, as the steveg longer lower rod I have came predrilled with a hole for the tab. So I’m going to find my best setting for it and drill at least one hole in the middle rod to match. Simply switching to the stock lower rod then be a shorter adjustment, if I add a tab to one of them also. I’ve got room to experiment as I have several each of both middle and lower rods.

Yea, twisting not that big of a deal, I can handle that but a Minelab or aftermarket fix will come along, sooner or later.

Righto awhile back I pulled the plastic nuts off the ferrules and cut 1/8inch off nuts this allows you to tighten extra without the thread binding as it does, so far works aok time will tell if this is a fix.

Don`t put your 6K down out of sight as if this fix doesn`t last you may find your 6Ks lost its nuts........😉

I have yet to experience the rod twist as my 6000 was defective right out of the box. Got it put together, charged the battery, turned it on - I emediatly knew something was amiss as it wasn't noisy like everyone says it is. I did a noise cancel and ground balanced it. I made sure threshold was on. I am in a backyard with power lines every where and the detector quieted right down, ran it over a 1.5 gram nugget and nothing. No response at all. It was as quiet as a mouse in the next county. I renoise cancelled and ground balanced and ran it over that nugget and other nuggets, even a quarter and no sound at all. In fact after I reground balanced the threshold went away. So I thought the coil might be bad so I switched to the 14"DD and tried both emi cancel and conductive ground cancel mode and still no target sound.  Well it has to be a defective machine. I also noticed two vertical shadow marks going down inside the LCD screen. Very faint, but when the sun is shining on it right you can see it. That morning I called Minelab and talked to Nikki and she said box it back up and send it back and we will replace it. They should be getting the new one in the mail today. Just my luck to get a defective one right out of the box. This was what I was afraid of with the 6000. As for the rod twist, that would annoy me, so I like Steve's idea of the grip stuff for golfer's or there has to be something else, maybe fixative spray for artwork, as it dries clear and hard and is designed to give a tooth to the surface to continue working and take medium.

Before my 17" coil arrived I had already ordered the parts needed to make my own shaft/lock pin extension
I used the lower part of a 5000 shaft and the lock pin at the other end, bought some carbon fibre glue and the job is done 

Total cost (if you have a old shaft) AU$45 and I can have the length I want

not to much of a big deal for me, ill straighten it out maybe once per hunt.
however, if you use the wireless headphones be careful with that charging cord, as mine just stopped working.
i had an extra power cord so not a big deal either.

Experiencing rod twist on my mine as well, if I keep the 6 I'll probably do some light sanding on the top of the shaft for added grip or do a drill and cotter pin through the shaft. I did purchase one of Steve (not Steve H)'s aftermarket longer shaft for it and it helped a lot....

I dont mind the shaft twisting. It usually takes a pretty good force to make it twist and its easy enough to twist back. Pushing down on the ground and then twist it back.   Also can be really handy to be able to twist it when you are on the edge of old workings or on a hillside. I also tend to find myself liking the controls turned in towards me. Just more comfortable. 

The only time I really had any issue is when the shaft was wet from a misty day. I could see a nice fix to be is to have longer locks. The added surface area would allow for more friction between the collar and the shaft which would in turn make it harder to twist.

      Morning everyone, 
      Had a search of the forum and although there are a few mentions of the 14" DD in various thread content I couldn't find a specific thread for discussion around it. 
      Did a video a few days ago getting a few small pieces of gold and small rubbish at a location I've found lots of small gold in a small area.  
      I know that I like watching videos and many of us often encourage others to do a video of this or that.  I figure that rather than asking everyone else to do it I should probably do some of the hard yards myself!  This is certainly not an advertisement of a Youtube channel and I have no illusions that my production quality or information provided is any better than fairly average  🤣
      Something for you Northern Hemisphere folk to watch during the cold months.  
      Happy for anyone to add to the discussion, link a video, show some DD finds or provide some tips on the thread.   
      The thing I found interesting about this was that the target shown at 3.55 mins was quite bright in Normal ground mode.  It ended up being no target at all and just a small pocket of really wet clay.  The fact that it brightened up with the DD surprises me.  The fact that it then brightened up quite a bit more in Normal maybe should have alerted me to the fact that it was ground noise and not a genuine target as the difference in signal on small pieces of gold swapping between Difficult and Normal has been quite small.
      Cheers, N.E.

      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.
      17" Searchcoil available here - https://www.robsdetectors.com/minelab-gpx-6000-17-searchcoil/

      stumbled onto a thread all about adjustable rods for the EQ800 that inspired me to search for an adjustable for the Monster.  Had no luck searching this forum and also the interweb, all I came up with was Doc's rod which doesn't interest me for my needs.  need something like the stock Minelab rod on the 6000 or very similar?
      Any ideas or links....?

      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.
