Gpx-6000 Normal Vs Difficult Timings

Recommended Posts

Has anybody done a quick air test on a U.S. Quarter or other large target with Normal vs Difficult Timings?

I have tested Normal vs Difficult and found that Normal is not deeper than difficult on large targets. (Manual 10 or Auto +1 Sensitivity)
I also get very broken or confused signals while using Normal at fringe depths while Difficult gives nice & clear high-low signals.

Do others notice normal timing giving greater depth on large targets over difficult timings on the 6000?

(There may be something wrong with my 6000. In addition to Normal giving zero extra depth for me,  I have received an intermittent "coil error" with both the 11" & 17" mono coil.  This usually happens after using the machine for some time in the field and once it starts, it won't stop even with a full factory reset. I have the machine scheduled to go back to Minelab and I am hoping they can reproduce the "coil error" fault I keep getting.)

i have not done too much testing with the 6k. i got it out of the box and into the field and have not looked back.
as for Normal vs Difficult Timings. in Normal i have have found myself digging hot ground targets then switching to Difficult, and the target disappears.
i now hunt mostly in Difficult, every location is different. manual when i can, a bit more sensitive, i think?
instead of using a U.S. Quarter, might i suggest lead. it often sounds very similar and preforms very much like gold.
i might have to do a bit of testing myself.

Hi Don. 

Can't say I have done a lot of air testing between Normal/Difficult but do find the same as Bishop outlined above re: ground noise.   Normal tends to liven up false signals a bit more in the areas that I work.  Extensive checking of targets over a few months showed that Difficult lost very little re: hearing a genuine target but it sure cleaned up the ground noise issues.  This is likely different in a lower mineralised area. 

I have not received a 'coil error' warning at any time since I've had my GPX6 so I think you're right in requesting Minelab to have a look at it.  

Next time I'm out I will try an air test of a coin between Normal and Difficult for my own interest.   

Hope you get it sorted  👍

It's entirely possible something is wrong with it. Mine was defective right out of the box. Sent it back the next morning after it arrived. I was told they have some new ones in box's they would send one back to me now they don't have any left due to defective ones coming in. Now they are telling me they will get my replacement sent out as soon as more come in. Who knows when that will be, a few days, weeks or months. Especially with how things are going with shipping.

Hey Guys,

   I have been hearing this, but have yet to have one of my customer with that problem yet.  Many are thinking it was a certain batch of serial numbers or units that could be defective.  I just got another batch in, so I'm hoping none of these are part of that group, if that is really the case.

Same with mine, defective out of the box, Minelab wanted me to send it in for repair, which I was not impressed with after my neighbor having just had his 4500 in for over a month for repair then having to send it back to get PROPERLY fixed as it came back with a different problem. It's fixed now but that was not a path I was looking forward to on a brand new detector..... Thankfully Doc stepped in and helped me get a replacement the next day.....

My 6 will be here this coming Wednesday. They made sure it is working properly before they sent it to me. The Detector Center are good folks.

      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/

      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.

      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.

      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.
