      A package I've been very much looking forward to arrived in the mail today, I call them the twins.  It made sense to package them both in one package for postage reasons and fortunately JW was working doing some renovations at his house around the corner from mine today so he had his a few minutes after the courier arrived at my place with the package as I shot straight over to give it to him. 
      I tore the box open to find them extremely well packaged


      And now the twins

      15x10 spiral wound X-coils, one for the GPZ, one for the GPX.  The GPZ's coils curly cord seems good to me.

      They came with a spare coil cover.  This is obviously the GPZ coil.

      And the GPX one.
      Hopefully I can find some gold soon with it, I've on a dry spell at the moment, although the football field of coins has kept me busy.  It's been about a month since I've attempted to find gold as my weekends are filled with skiing as my daughter is addicted to it and my week days have been busy doing the local coin hunting, now this coil has arrived I best get out there soon.  It snowed yesterday and today there is a freezing wind blowing off the snow, if it wasn't for that I'd be shooting off now to test it out.  Only about 2 weeks left of ski season.
      JW's been doing pretty well lately with his 10x9" X-coil and he rarely takes it off he loves it so much so it will be interesting to see how he goes with this new one being spiral (flat wound) when his 10x9" is bundle wound.

      I just couldn't figure it out. The old Jeep mysteriously started running much smoother and quieter and became much more stable. I would also say that it's performance somehow increased by 30% or perhaps even 40%. In fact i was so impressed i decided I would invest some time into cleaning it up a bit. As I was mucking out the interior ( forgotten rock samples, sticks and leaves, old sandwich wrappers with sandwiches, dropped nuggets and such) I found Sourdough Scott's missing ferrite ring. I took it out and put it where Scott could pick it up and now the Jeep is back to it's usual squeaky, whinny, worbally self.
       Mystery solved.

      I always wondered if there was even gold around where the X-coil manufacturer lives, I didn't know much about Russian gold or if Russia even had much gold.
      Here is a video broken into parts of the Russian manufacturer showing the different capabilities of the 17x12" X-Coil between the Standard GPZ14” Minelab coil being used near high voltage power lines in Russia.
      It's good to see he is a prospector.
      Sorry about the quality of some of the parts. 
      It's a deep hole he has to dig to get it, nice soft soil though... that'd make life easier than using a jackhammer 🙂

      Hello fellow prospectors,
      I recently acquired a Minelab GPZ 7000 and I am looking for a fellow prospector wanting to search for gold with me in Southern California. As a former FBI agent, I have learned it is better to have two people when exploring unknown places... I have been using a Minelab CTX 3030 and I am ready for something new i.e. gold prospecting. I live in Long Beach but  I also have a home in the Lake Arrowhead area (San Bernardino County). I believe some areas are worth prospecting in San Bernardino County. Having said that, I am willing to travel. Reach out if you are interested. ads4350@gmail.com

      I was going to post this in one of the X Coil threads, but it might be of interest to everyone.
      I bought a replacement ferrite ring since I left my ML ferrite in Arizona. It's one of the Doc's ferrites with the white backside (off Ebay), I did not realize they were not ML ferrites when I bought it. The OEM Minelab ferrites have a black backside.
      It would not balance on the X Coils at all and actually sounded like a screaming target (I didn't try the Z14) so I reported that to the coil manufacturer. He responded that the white backed aftermarket rings are not the same as the ML rings. So, as I normally do, I checked for myself, bought an authentic ML ring, and he was right.
      They are the same size, but the Doc's ring is 10 grams heavier (something I noticed immediately but did not have a ML ring to compare to until recently). It is also more magnetic. The Doc's ring is also conductive whereas the ML ring is non-conductive - the Doc's ring was reading about 38 ohms from side to side whereas the ML ring read infinity. And after I sanded the backs to get a fresh surface to check resistances on I noticed the ML ring looks dull and black as a ferrite should, but the Doc's ring looks shiny and metallic, like iron.
      So, clearly there are differences between the two rings. Thought people might like to know even if you are just using the stock coil, as I'm not sure how this affects the ground balance, but someone could be running suboptimally using this ring.

      I often see others using a high sensitivity setting of 16 - 20 on the 7000. Is there really much of an advantage doing this? I used to think maxing out my 4500 gave me some kind of advantage over the poor suckers who ran factory presets or slightly higher, now im not so convinced. 
      Today i tested out my new 10" and 20" X-coils and tried many different combinations of settings to see what would suite me best. I did most of my testing with the 20" coil on a 2 gram bit of gold. I dug a skinny trench 200mm (nearly 8 inches) in some reasonably hot ground and placed my 2 gram bit in the bottom. High yield/Difficult were the better settings. (Ferrite and ground balanced, Semi auto ground balance,  Ground/audio smoothing off,  volume 8 (using a booster),  threshold 27,  threshold pitch 63,  volume limit 7)
      First i tried a high sensitivity and the target signal popped out nice and loud. Then I started detecting the surrounding area and felt there was so much other ground noises going on that the quieter signals may be masked. Eventually I found my sweet spot where the detector was quiet as a mouse and i had no problems hearing a slight change in the threshold no matter how small it was. This was at a sensitivity of only 3.
      I then went back over the 2 gram bit and it still gave a great response using sensitivity of 3 (although slightly less than when the sensitivity was a lot higher).
      When i started detecting and raising the sensitivity up around 6 -8 a lot more ground noise came in. Now im used to ground noise as i used to use my gpx in Normal timings most of the time. But after reading how the zed is a different beast and not to drive it to hard i decided to try less aggressive settings to see if less is infact more. Obviously im new to the zed and have much to learn so will continue trying different things until i get my head around things.
