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.
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. firstname.lastname@example.org
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.
Here is a recent video of a couple of dudes testing out their massive range of Nugget Finder coils against the GPZ 7000 on targets they've dug into the ground in Western Australia's red dirt. I found it quite an interesting video and shows how close a lot of coils are in performance.
I notice he doesn't appear to scrub the GPZ on the ground as much as the others, not sure the reason for that, maybe he doesn't want to damage such an expensive coil ?
By the time he's got to the GPZ all the ground scrubbing has probably made it a shallower target.

Out here in Arizona, USA, it's been very hot and now humid as the Monsoons are right around the corner. That being said, I have been poking around an old placer location loaded with iron rubbish in search for overlooked gold nuggets. I have made it a point to start very early, right at day break and hunt until the heat runs me out (typically 4-5 hours). I was using the Minelab GPZ 7000 and placering a wash bottom down to bedrock like the old-timers would. I'm lucky every so often to get a nugget here and there wedged in the bedrock cracks/crevices that the old-timers missed or overlooked. It's always a mystery to wonder what the old-timers really discovered in some of these really rich coarse gold placer areas.
I'm not sure of the rules about Youtube videos, but I have attached two of them for your viewing. Hope some of you that are not able to get out right now can enjoy the adventure with me.
