  1. Jason What an ordeal you have been through. Hopefully things will improve now. Maybe you will hit a rich patch and put some of this behind you. Have a good day, Chet
  2. K4PI Mike Three alternate ideas; attach a hand wound loop/inductor to the end of long pole. With two wires connected to an Inductance meter, a Grid Leak meter or a Beat Frequency Oscillator (BFO). Slide the loop around and along the length of your antenna element looking for a change in reading. I hope one of these will work for you, Chet
  3. The battery is easy to replace. Just four Torx screws to open the case. No soldering required. Several batteries are available on eBay. Have a good day, Chet https://www.ebay.com/itm/0303-0036-New-Battery-for-Minelab-CTX-3030-WM-10-1100mAh-Equipment-Survey/133298441706?hash=item1f0934cdea:g:k78AAOSwtgNeFn6v
  4. The charge socket for the WM12 is a Universal Serial Bus (USB). The international specification for USB version 3.0 limits the charging current to less than 1.5 amps per socket. So the WM12 and USB charging cable is designed to comply with this standard. The battery charger circuit is designed by Minelab to safely charge the battery at a higher limited ampere rate that will not overheat or damage the battery. Have a good day, Chet
  5. I found this information informative and interesting. It shows some of the similarities and differences of Australian and U.S. laws and regulations. Have a good day, Chet
  6. Paul I carry the 7000 on a bungee in my right hand and a 800 in my left hand for discrimination. And they both act as canes when I stagger on the loose boulders. Discrimination works on the small shallow stuff. Be prepared to move a lot of big boulders for deep big stuff like this. Have a good day, Chet
  7. Jason Great results and great report. Thank you and have a good day, Chet
  8. Jason, thank you for the hours of effort and the great report. Have a good day, Chet
  9. It could happen this way; so keep a boat handy. https://www.cagle.com/tag/seismograph/
  10. JW Thank you; and congratulations on your finds. I experience similar hot rocks; I don’t like the big underground pointy ones that tend to give a sharp nugget type response. Fred It was about 10 miles south of Interstate 40 highway on Havasu Gold Seekers claims. I did hunt the meteorite strewn field a few years ago for three days. No meteorites were found but again lots of bullets. Photo attached. Beatup thank you. Brian The plan was to gather data for two more comparison charts. The last two days where raining and cold so I cut the trip short. I will try again on the next trip. Steve You are right on; the short wires are near the surface and can be found quickly with a little scrapping and a strong magnet. The long wires when in a wash can be quite deep and some hunting for just like a small nugget. Have a good day, Chet
  11. My first outing with the 15” x 10” X-Coil was a very satisfying experience. Settings used are; High Yield, Normal, Freq. Auto, Sens 20, Volume 12,Threshold 1, Tone 53, Vol Limit 12, Auto Smoothing Off, Ground Balance Auto, GS Off I ran a quick test on a 0.08 gram test nugget with the 10” round which produces some noise and false target responses when running with my wide open settings. Changed to the new 15” x 10” X-Coil and ran over the 0.08 test nugget again. Both coils were getting a good loud response at approximately 3.5 inches. I ran the 15” x 10” coil for 5 hours a day for 5 days. It was stable and quiet (except for a little very low level EMI). The noise and false target responses experienced previously with the 10” round coil were gone. There were no problems with ferrite balancing. Franconia, AZ has produced some large nuggets. A 3 lb quartz rock with 15.9 oz. of gold was found there the previous week. It was a US Army Air to Air gunnery practice range during WW2. So you are forced to dig a lot of deep targets. There are a lot of bullets and small pieces of screen wire blasted from the towed targets. I only found two small nuggets between bullets and wire pieces. They are 0.6 g and 0.2 g. Overall this is a very sensitive coil and a pleasure to have the lighter weight and ability to get into smaller spaces. Have a good day, Chet
  12. Hi Flakmagnet That is a good procedure. Sometimes I have experienced ground with reddish rocks that would not ferrite balance at all. I look around for better looking ground and balance with a little more effort since I had knocked it way out while trying on the hot ground. Sometimes it won’t quiet down as much as normal. But later hundreds of feet away on some different ground it balances fine. Have a good day, Chet
  13. Hi Flakmagnet I just recently joined the WSPA at Bill’s last outing near Morristown. Hopefully it will provide some new possibilities and activities. I look forward to meeting you and more of the members. Have a good day, Chet
  14. Hi Flakmagnet It might be worthwhile to get with a dealer or another GPZ 7000 owner to compare detector performance and procedures. Or join a club that has some GPZ owners. There are many benefits to belonging to a club. There are a few of us GPZ 7000 owners at Bill Southern’s Spring and Fall outings in Arizona. The next one is near Quartzsite March 20-22. It’s a lot of fun and the cost is the price of a pot-luck dish. Have a good day, Chet
