X Coil Connection Problems

Recommended Posts

Nothing wrong the motherboard as the detector still works fine with the Minelab coil.

 I doubt that the multimeter caused the problem because it was not working first, that’s why we tested it, and we didn’t touch the 3 small pins with it.  Thank you for the info Chet.

My thought from the start was that it must be the coil, as the original patch lead was done exactly as per instructions and looked to be a very fine job.  

We are about 6hrs away from the nearest McDonalds here Mitchel, no electronic stores out this way.

With all the doomsday scenarios you blokes have came up with I am glad to be testing with someone else’s detector 😂

Will give an update once we get to try another coil.

Does the manufacturer send a replacement coil in this case, or is that still to be determined?

I'm sure a faulty coil would be replaced but still.... with a bad coil you'd be more likely to get a coil that doesn't work well, not one that's not seen at all.... I'm still placing my bets on the chip.

Here is an easy test for you, why not put a microphone end back on the coil the chip was cut off and test the original coil using the patch lead.  That will tell you if it's the coil or the patch lead.

When I said people had asked about things 'here' I didn't mean about on the forum but HERE in the United States.  Many of us can't solder or have the soldering equipment although we could go to Harbor Freight and get that stuff for under $20!

Steve probably did it right.  

So ... there is still a problem I hope you have fixed already.

When I make the patch leads I also put another plug on to the original coil. That way it can still be used. Have you tried the original coil with the patch lead? If it works then the fault is with the x coil. If not then either the patch lead is wired incorrectly or the ic in the plug has been damaged.

I recall JP mentioning this issue in the past but this is the first user I've seen post about it. I dont watch other forums, are other people having this problem too? How common is it?

My original Zed 14" coil housing got damaged.  It still worked and detected gold, but it was getting really touchy in desert weeds and undergrowth.  I used the coil connector from that coil to make the patch lead.  I followed all the directions on soldering, but the first chance to check it was when I got to WA, as the new X coil was waiting for me out here.  When it wouldn't work out here, Trent gave the connection a pretty good going over visually and then checked the continuity,  So, I don't have the original coil and the corresponding 5 pin female connection to make the necessary compatibility check.  

Dave mentioned that he had a spare patch lead, as soon as he surfaces hopefully we can do some swapping to check as to whether it is the coil or the patch lead.

Apparently he is aware of the problem.    I hope you get this problem sorted quickly   Dave

He was likely referring to this exact case at that time and it's been going on for some time.  The issue is caused if there is a problem with the patch lead.

If a bad patch lead is made up the coils won't work... It's not the coils fault in a situation like that.

Not anything against Condors soldering skills but accidents can happen. It's more likely a bad coil patch lead made than a faulty coil, coils would be tested at the time being made and not many problems with a coil would cause it not to detect at all other than a chip that's there to prevent fake coils going on.

I will be interesting to see how it plays out when the coil is tried with a known working adapter.

Does your Z work with Dennis' coil or any other Z coil in the camp?

      Hey Steve,
          You and I have known each other for a long time, even had some great times metal detecting together.  That being said, the X-coils at this point scare me off.  I had an opportunity a month or so ago to test several different sizes from someone that is affiliated with the manufacture.  I was a bit excited at first, then found out I would have to cut/modify an adapter/chip from another GPZ coil to use one of the X-coils.  
      To me, the trade off to damage or destroy a $600 - $1500 coil to just get an adapter to work on an X-coil is not my cup of tea.  I don't need a smaller coil that bad to do this.  That being said, other guys like to modify/fix/tinkle or whatever might enjoy this.  
      I find the GPZ 7000 stock coil plenty sensitive enough to find gold down to a grain in size.  However, a smaller coil like an 11" or so would be nice for tighter areas or areas with more vegetation.  
      We were kind of promised a smaller coil originally from Minelab and that never happened.  I think one more smaller coil from Minelab would have eliminated most of this stuff about smaller coils. 
      Keep in mind, at one point I sold more Coiltek searchcoils across the US than any other dealer.  I could probably sell a ton of the X-coils, but not at the cost of sacrificing a detectors warranty.  
      For the benefit of all GPZ owners, I hope someone like Coiltek, Nuggetfinder, Minelab, X-coils or whoever can find a better way to make a coil that will just plug right into the GPZ and work.  
      Just my thoughts,
      Rob Allison

      Latest 12" X mission over, was staying out 2 nights but the frost sent me home to the warm bed, plus I lost my pick, walked couple of ks blew a couple of hours and could not find it. Yeah, yeah I know how can one lose a 3ft long pick, done it before will no doubt do it again. I am convinced there is a pick stealing triantiwontigong that exists on all gold fields I have visited.
      Lot of talk about settings and ground balancing methods lately, as we have often discussed before, these are individual settings and no one has the correct settings for anyone but themselves.
      Very simply my current, and I say current because I will go with what gets the gold whether settings or hardware. Settings are semi auto, general, no audio or ground smoothing, volume 7, threshold 24-27 depending on wind noise (WM12 no booster or h/phones) normal mostly but difficult when patch hunting usually, sensitivity between 8-20. Ground balance is.... no use of Quick track button, no ferrite simply let the Z do it`s thing, it is next to the SDC the easiest gold detector I`ve ever used. KISS (Keep It Simple Sir) occasionally as I`ve said years back I`ll go into manual but very rarely as it requires having to fool the Z into doing a Quick Track. ML if you listening give us firmware that has an option allowing us to avoid this forcing of QT. I am very sure I am not the Lone Ranger in this request.

      4 Sundays ago Simon & I headed off to an old haunt.

      Simon with his QED & me with the Zed & 10 x 9 X coil. I had been here once previously with the same set up & had got 8 bits of gold.

      This time the ground was quite moist from frost conditions & thawing out. So I liked my chances of getting some more as I always maintain that these moist conditions improve sensitivity & depth. I was running High Yield/Normal. Full max sensitivity of 20. Going extra slow, rubbing the ground & over areas I had got gold off before. It took a while to get a faint little hit on an old timers throw out pile.

      Down about 4 inches the signal had moved so I was convinced it wasn't going to be a pellet . Gosh...wasn't much bigger than one.

      Got another signal in the same throw out pile just above the first. I had flattened some grasses that were quite weak & folded down easily. Bang. Got a good hit.

      you will see the first dig to the lower left.
      Out popped this.

      Then above that dig I got another hit.

      Crazy.

      So three bit in very short succession off this one pile.

      For no reason I flipped over this flat schist slab & bugger me, I got a signal

      A beautiful sweet mellow gold signal.

      And gold it was.
      Then on another old throw out pile I get another sweet little hit.

      Wasn't too deep but for the size of the gold I was stunned.

      Thats Gold Monster size gold.
      It didn't end there. On the same pile. A couple of scrapes.

      Another tiny bit

      On top of some schist bed rock another faint but positive signal.

      Another small bit of gold.

       

      Prior to this Simon's QED batteries had died. Bugger. Then I remembered that I had the GB2 & the Gold Monster back in my wagon, which wasn't too far away. So off Simon went & came back with the GM 1000. We then had a coffee & lunch break.
      My last bit for the day was down a bit of a gut. Notice Simon at the top waving the GM 1000. He didn't fair too well this day on the gold.

      I was surprised at the depth of this dig & the very good signal. Thinking it was going to be a reasonable piece.

      Wrong. But still gold. no catch & release.

      All up 11 pieces for 1.08 grams.

      Another successful X coil day out there on ground that had given up producing with the standard 14" Zed ML coil.  Loving these coils   Cheers.
      Best of luck out there

      It’s very nice that X Coil is getting a ton of free advertising via this forum but it appears I am the one getting the headache.  I have been doing the best I can to keep a lid on the dumpster fire, but now I am getting messages accusing me of somehow being biased simply for hosting the discussion.
      I was approached by the Russians early on but declined as it was easy for me to see it was going to be a can of worms. So I have no pony in this race. I think forum members deserve to hear all the pros and cons and I am not in a position to say who is right or who is wrong. My view is that I just try and keep it moderated as best I can and let forum members decide who and what they want to believe.
      davgold as a dealer obviously has an interest in the coils looking good. JP has brought up some issues but it seems some have problems with him doing that or the way he is doing it. I have a personal friend who has a bricked GPZ due to his attempt to use an X Coil. It’s not the first I have heard of either. You could perhaps say that his fault but really he knows his stuff so I am more inclined to say that there are risks that are real here. I can see pros and cons and am very loathe to shut down any one side.
      I am willing to keep trying my best to keep the ship on an even keel as long as the general forum members are learning anything of value. I am also just as willing to lock all the X Coil threads and ban new ones if people have had enough of it.
      Lest anyone think I am upset that’s not the case. Typical tempest in a teapot with people thinking metal detecting is some kind of life and death thing. But new members joining to pick sides and send me messages trying to shut one or the other side down will not work so give that up. I am only interested in what the longer term members think on this particular issue.
      I would like to here from longer term forum members that are involved in the threads to either give me some direction via this thread or PM me with their thoughts if that seems better. It may be that most people are fine and that would be good to know also. By most forum standards it’s pretty tame stuff but I am protective of the general forum membership and don’t want to assume I know what you all think. Thanks in advance for your help.

      17 x 12 Spiral, pings tiny .1 gram bits no worries. Pain in the butt digging them but sometimes they lead to bigger and better chunks as was the case for me today. 76 grams at 18 inches, any detector would have heard it, same with the 6 gram bit. 14 gram bit was a different story, 20 inches down and very quite but definitely a dig me signal. With the X running so quiet it was no worries. A bloody pleasure to use, a complete contrast to my stock 14” which is so touch and knock sensitive, it’s had a hard life so maybe just worn out but it never ran as quite as the X.

      Interesting. This new Youtube channel popped up recently for somebody calling themselves X Coils
      https://www.youtube.com/channel/UCQEHSSBIdi5fWH26IS12v4A
      It appears to be Russian? and they appear to be working on coils for the GPZ. Here is a peek at the 12" x 10". Personally, that's a bit too similar to the stock coil to interest me - I would rather see a 10" x 8". Still, it's interesting that somebody has managed to make some coils that might work on the GPZ without blowing it up. This is one detector that I will have to let others gamble with first on this sort of thing but I knew you would all find it interesting.
      They also are showing a 16" round coil....
