Has anyone had any issues with their coil chip failing?

l bought a second hand 19” coil for my GPZ and it worked fine for several months and then out of the blue, it failed.

Minelab suggested that I buy a new coil. After a bit of research I decided to have a dongle made up from my 14” coil and now 12 or so months later the chip in the dongle has failed. Am I doing something wrong? Is there a problem with the detector or am I just very unlucky?

If two chips have failed then it could be a coil problem. 

My two bob's worth anyway -

Further to what JR said, did the dongle fail when the 19" was attached or the 14"? 

If the 19" was attached and therefore has been attached whilst 2 chips have failed that would further support JR's suggestion.

The chip failed in the 19” coil and then in the 14”.  I’m certainly no expert and could well be wrong but chips seemed to fail in two separate coils. I would think it unlikely that both coils were faulty.

OK. In that case you probably need to get the detector checked out.

And if it is the detector I would think you have a case for coil replacement if all is still in warranty period.

      Is there or has there been any comparison testing done in the field on depth with the 6000 vs the 7000 using the NF 12" Z-search coil.
      Thanks . . .

      I haven't done a story on a gold find for a while, partly because once you find a patch with a bunch of nuggets everything else seems pretty insignificant, a couple of months ago  I did just that, it's only my second patch but had quite a number of nuggets, I'd guess at least 40 (Correction: at least 80 nuggets) and over 30 grams in total.   I lost count of both the nuggets and the grams we got out of it in the end.  I did take a couple of videos on the first and second day of it, after that I stopped filming and just worried about detecting as filming videos is very time consuming and wastes valuable detecting time 🙂   That patch has been the highlight of my detecting time and hopefully I can find another in the future, I'll put links to the videos for anyone that wants to watch them and hasn't seen them already.

      Now to the more recent adventure, one of the most common gold spots I've been to is being developed, very soon it will no longer exist, already a large area of it has disappeared over the past few months with more to go yet, seeing it's probably the closest gold spot to home and one I've found a reasonable amount of gold before so it will be missed greatly.  It's obviously getting extremely hard to find gold there as it's not a huge area really and it's been done a lot over the years by a number of people being an obvious spot to look.
      My focus on this day was to take advantage of how well the GPZ and Concentric coil handles EMI to hunt almost exclusive in and around the power lines where people including myself with previous setups were unable to really detect very well, especially with my GPX 4500, it was terrible near the power lines, and what inspired me to try out a QED which ended up working quite well under the power lines but just didn't have the power of the GPZ.
      I didn't take all that many photos as my aim was to get some video, I always struggle to get gold finds on video as I just use my phone to film and I have to put it down to do the recovery 🙂 I have a GoPro but just haven't bothered to use it yet. 
      I went to some bedrock and worked my way up digging every signal and recording and deleting all the recordings as they were turning out to be shotgun pellets, this is entirely normal in this area as it has a big rabbit plague and shooters love spreading their pellets around all over the place for me to dig back up again.
      Here is a video of the first gold find, a .109 of a gram nugget, I was pretty happy with that to start the day as often at this location I go home empty handed.  I didn't get the entire thing on video and I had my detector in difficult from when I was messing around the other day doing some testing and didn't check my settings, I'd never normally use difficult in my soil as Normal works just fine. Fortunately it didn't prevent me finding the gold, or the numerous pellets before it 
      Once I'd finished that bedrock area I walked up under the power lines to detect hoping I'd find something others couldn't get, I took a little video there of how the detector was working under the lines, I really love how well the GPZ handles power lines seeing they're in many of my gold areas.  You'll also notice at the end of the video the millions of bits of rabbit poo on the ground, this is the reason for the shotgun pellets everywhere.
      You'll notice in the video I discover I'm in difficult and seem a bit surprised, this is when I worked out I may have wasted the past hour detecting in difficult and it went through my head now I'll have to go check that bedrock again 😛  I was quite happy at that point I took the video or I may not have noticed for the rest of the day.
      I started detecting along under the power lines and ended up in a little area I don't think I've been into before, I'm terrible with directions and locations so it's quite possible I have been there before and don't remember it but it didn't look familiar, I was still recording every target dig to try get a gold find on video and managed to do it, I think this might be my first time ever getting one from start to finish on video, quite happy with that.
      And a couple of photos of it.

      And my lucky last nugget of the day if you could call it that was a 0.038 of a gram nugget, very shallow on some bedrock, it took me about 20 minutes to recover this one, but I only got a portion of it on video, I kept moving it around but couldn't pick it up, I had no idea where it was in the cleared area, I was wishing I had a VLF with me with tiny coil to narrow it down.



      I'd imagine there are quite a lot of these little guys around it's just the amount of pellets you'd have to dig to find them would be crazy.  I do it more for the challenge but the novelty wears off after digging a massive amount of pellets and not finding any nuggets and if you ignore the pellets you'll miss these little bits of gold. 
      So here are the 3 little bits for the day

      and the weights

      All a bit of good fun, I really enjoy chasing these little bits especially after the first one pops up to get you into gear looking for more.  I can't compete with the photos lately out of Alaska for gold though, I'm just glad I can do the hobby near home and find a few bits to keep me happy.
      Here is a little tour video of where I was detecting.
      Keep in mind to run these coils you need to have an adapter and that involves cutting the end off your existing GPZ coil and making an adapter out of it, it should only ever be taken on by someone very skilled at electronics or really the best thing to do is get a professional to make the adapter for you to avoid any problems.

      I change coils more than most, in fact I've changed coils 10 times in a day when testing out various coils on bits of gold, by doing this I'd caused myself some lower shaft wobble, it turns out I'd cracked part of a clip on the shaft, the clip with the little rubber pad had a crack in it, so the shaft wasn't holding on tight.  I suspect the people that had upper shaft issues where it wobbles a bit have either got the same crack on the pressure pad or they've just worn the little bit of rubber out.  Fortunately it's a very easy and cheap fix.
      Here are the part numbers for the clip mechanism
      X2 8008-0056 Pressure blocks
      X1 8008-0072 Camlock lever
      X1 4308-0033 Pin
      The part I'd broken was the pressure blocks.  They come in a twin pack for replacement and are very easy to replace.

      You dismantle the clip by removing the pin, I used a small screw driver to push it out of the clip.  You then just use a small flat head screw driver to lever them off, pushing each side of the pressure block away from the camlock lever as pictured below.


      This is the shaft with the clip removed.  You can see the grooves cut out of it where the pressure pads need to slide into so when reassembling made sure they're straight so they fit into the groove.

      You can see the little circular lump on the left hand side pressure pad, it's what goes into that dug out groove.

      This is how the rubber pads look, I guess they can wear out over time and if they do your shaft would be wobbly.

      Minelab sell all the parts individually, so you can just order what you need for the repair.  They were very helpful with me, and had me solved by the next day using express shipping.  I bought a heap of the little parts so I have spares seeing I change coils so often.
      In my case I just needed the pressure blocks, the pin and camlock lever were obviously fine.
      So if anyone's putting up with some shaft wobble, it's cheap and simple to fix.

      I’ve been following the battle between the old dog (GPZ-7000) and young dog (GPX-6000) with keen interest.. From what I can make of it, the young dog’s winning its battles in the USA and the old dog in Australia.. So far it seems the old dog can handle a scruff on heavily mineralized and ‘hot rock’ infested grounds better than the young dog, who prefers milder grounds.. But it’s too early in the day to scorn the young dog, it’s only just finding its feet in the world.. The old dog might’ve fought it out with other GPXs and always come out on top, but this young dog seems to have more sense of geology than its cousins.. Maybe a few more dust-ups in the old dog’s yard might do the young dog some good.. Or maybe the old dog won’t let the young dog anywhere near its yard no more? Maybe they should flog it out on neutral grounds somewhere, another 'Rumble in the Jungle'? Only time will tell who emerges Top Dog of the World , as with most other dog fights.. Hackles come up and fur starts to fly..
