  1. @phrunt Can you put a tape measure against the Target ID...looks like about 1/2" tall? Bill
  2. @phrunt I haven't been able to find the Target ID font size on the 2.7" LCD screen, which seems very busy. The Manticore Target ID is great! Can you clearly see the Target ID while standing or do you need to bend over? Is it possible to increase font size on the LCD? Some of us older guys have problems reading the "fine print" on today's packaging.😂 Bill
  3. @Doc Thanks for helping me last nite on the hip stick order! Your engineering knowledge & manufacturing background + metal detecting experience will greatly improve future hip stick & harness designs(better than ML Pro Swing). Keep us informed on the next accessory to purchase, we need you!😁 Bill Moore Laporte, CO.
  4. @AmgminingcoGuess I should have asked for the GPZ settings, which I'll probably use more often...like you did! Were you running Extra Deep, General or High Yield? Thanks, Bill
  5. @AmgminingcoGood story and big, beautiful gold! I have also sold my GPX 5000s twice, kept my NF Evolution coils and just recently picked up another used one from Gerry. Can you share what settings worked for you? Thanks and looking forward to more stories and gold pics. Bill
  6. @jasong Great project and very complicated for us dinosaurs!😂 I watched The Prospecting Geologist YT video this morning on 3D & LIDAR and got lost after 3 minutes. You could make some good money printing maps for customers(I would buy one on NNV) and I guess we know where your headed next. Happy Thanksgiving, Bill
  7. DSMITH, Maybe @steveg (Steve's Detector Rods) can produce them in OK and distribute them in CONUS? Not sure about patent infringement...only @nvchris (Chris Porter) can answer that one. Happy Thanksgiving, Bill
  8. DSMITH, I use & love my hipstick and you may have to contact Chris Porter or order one from JP in AUS: Bill
  9. Keith, beautiful gold you found at RP. Was this area heavily hunted in the past and missed by other detectors, coils, settings? You must have had some open areas between sage bushes to swing that GPZ 19" coil. Thanks, Bill
  10. @jasong I've given up on the concept of trying the Mothership drag coil setup, too many problems with coil control (Doc said it's a PITA around bushes/rocks) reduced sensitivity and depth. Now I'm looking for a 22" CC coil for better coverage, sensitivity and depth. I've heard, just last week, there are still big lunkers being found in NNV and it's time for me to find my first 1 oz+. Keep those reports coming. Bill
  11. @Gerry in Idaho wrote this Silver & Gold edition W&ET magazine article back in 2009 and there is lots of good info in it. Bill PlacerDigsWE&T.pdf
  12. @phrunt WOW, that's amazing...gotta make the blood flow, gonna need a bigger pick/backhoe. Love his bungee setup, any idea who makes that? @1515Art I hear you, but the GPZ is still the BEAST, just need some accessories to take the load off your body. Thanks, Bill
  13. @Northeast Thanks for your detailed reply, not much info is available online & I also found a WA post that said "the AI coil must be run in DD mode and there was a massive loss of sensitivity and depth". Maybe better to try Woody's www.detectormods.com concept, can change layouts, save some frustration, time and money: Bill
  14. @jrbeatty I've been thinking about finding bigger deep gold in the US and recently heard about a 6 ouncer found with the GPX 6000 in NV. The old timers found alot of big deep gold in AZ and NV using analog SD 2100s, GPs and 18" coils, but they never had access to larger coils like we have today. I keep reading your exciting big lunker posts and those from @Reg Wilson, lots of good stuff! I'm planning for 2024 and wanted your insights before taking the X Coil CC large coil leap. This post is now over 2 years old, any thoughts you guys can share or updates from Australia? @jasong I was wondering about using the 22" X Coil CC in NNV, since the RX coil would limit searching in tight rocky/brush areas. I also read on X Coils FB page that you have to overlap swings alot to insure good ground coverage. I was also curious about it's ability to locate big deep gold and would you be able to run in General or Extra Deep with Normal Ground type(for max depth). Definitely a BIG investment ($2,100 AUS plus a Western Union transaction) for one heavy 1300 gram coil!😁 Have you had a chance to run your coil in NV or AZ yet? @1515Art Has a 22" CC, maybe he can update us and chime in. Bill
  15. @Northeast I'm also contemplating a cart/sled setup for deeper gold in flat areas. Here is a pic of one of Doc's designs using an SD 2100, according to Trevor @Coiltek the older ML analog SD & GP units work best with large coils. What did you decide? Bill
  16. Chuck, I went several years ago before they moved the Base Camp up the hill...accommodations look alot nicer. The hospitality of the owners, friendliness of other hunters, and some AMAZING local seafood was the best I've ever had, anywhere. I found one 6 gram iron covered gold nugget on the old Snowflake claim (loaded with iron, railroad spikes, etc.), my biggest nugget to date. Make sure you reserve an ATV, lot's of ground to cover and most spots are miles away. Plenty of mosquitos (bring repellant) and bring lots of cash...Betty sells large gold nuggets at the end of your week... in case you don't find some. It's not the gold you find, it's the golden memories and friendships you make that counts.😁 Bill
  17. Jeff, where are you at in AZ.? Maybe we can meet while I'm in Q 19 - 22 March? Bill
  18. Rolland, One of the biggest contributors to EMI and instability that I have seen is detectorists having their cell phones on while in their pockets. I was helping a friend with his brand new ML GPX 5000 at Rich Hill, AZ. and my 5000 was running dead quiet, while his was unstable and noisy. I asked him to empty his pockets...his cell was on, he had car and house keys, change, a wallet and other items. Once he removed all those metal and electrical items, his GPX 5000 ran quiet.🤔 Bill
  19. I've been checking Cabelas, BB, KCo, & other's, no ML Manticore units to be found. Bill
  20. Steve, I thought you sold AK Mining, are you back as an owner in the business, a consultant, or??? I went into the store several years ago, very impressive for AK and a great asset for miners. Wish we had a brick & mortar store like that in the USA. Thanks, Bill
  21. Wes, Please explain to us non-Baja risk takers/explorers what the "dug 1 mill in one season" means...1 million grams, ounces, $ of gold nuggets??? We want details and you guys should write a book.😁 Bill
  22. Gerry, I've heard from a reliable source that the SunRay headphones are going out of business now that Joe D. has passed and nobody wants to buy his business. Glad that I have 2 pairs available, nothing comes close to what "John" makes! Bill
  23. I found Condor's 2016 post and thought I would share it as most of the replies on this thread don't have an earbud or headphone solution: Disclaimer: My testing is not rigorous nor scientific in any way. Individual hearing is highly subjective and what works for me may not work for you. As always your mileage may vary. Detector: Minelab 7000 - HY, Normal, Sens 20, Volume max Earphones: Etymotic 4s 100 ohm impedance Adapter: APureSound 75 ohm impedance 1/4 inch headphone jack conversion to 1/8 earphone jack. Amplifier: FiiO A3 I have always used the Ety earphones in all my previous GPX detectors. Headphones are just too hot and cumbersome for me. The Ety's are top of the line In Ear Monitors with balanced armatures. Ety was primarily a hearing aid manufacturer and got into the earphone market for high end earphones. The 4s cost in the neighborhood of $300.00. Their 3 flange silicone ear piece is super noise isolating, but not particularly comfortable. If you are worried about hearing snakes, cougars, bears and such, you won't like this much noise isolation. Until I went out with Lucky Lundy I was very happy with using the WM12 external speaker for all my detecting. But after seeing his results with really good headphones, I was convinced I was missing some of the super faint targets. I switched to another brand of earphone while I was out there at Rye Patch and was getting decent results but the audio was harsh giving me more of an audio fatigue. So, for the past couple days I've been playing around with different audio setups trying to find a good balance. After locating a few undug faint targets, I switched back and forth between audio setups over these targets. My results were interesting but not particularly life changing. Adding 75 ohms of impedance bringing my total impedance to 175 lowered the available volume sufficiently for my 62 yr old impaired hearing that I added the mini music amplifier to give me more volume. My unscientific impression of adding more impedance felt like adding audio "smoothing". The audio seemed a little more stable and less jittery. Again, I switched back and forth over the same targets adding impedance and then without it. I even switched between the wireless WM12 and a direct connection to the detector, which did not seem to make any difference in the quality of the tone. I also ran Beats sports earphones with 27 ohms impedance. The audio sounded really harsh with too much uncomfortable scratchy highs. Adding the impedance made them tolerable, but not great. Results: Running 175 ohms impedance produced a smoother, more stable background but lowered audio volume. The most significant thing I found in my testing was playing around with the Threshold. I had been running Threshold at low 30's with the external speaker, but with the earphones that's just too much "noise" too close to the earbones. With these In Ear setups I found that I could run the Threshold at 0 and get perfectly identifiable target tones over these tiny, tiny targets. The best I can describe it is the detector has a rhythm of background beeps and bleeps, but over a tiny target the beeps stretch into a faint hum. A good target will come through loud and clear without any confusion. My target results are impressive. The smallest nugget is .09 gram. I found all these over the past 2 mornings in ground that I've been over dozens of times. I am certain that the earphones with their noise isolation improved my results, but adding the impedance probably just made the audio a little more comfortable. Bottom line, good aftermarket headphones already have between 100 and 200 ohms of impedance. Frankly, I don't think adding more than that will produce much benefit. Adding the mini amp helped me, especially running with 0 Threshold.
  24. Phrunt, so what do you use for windy days...the Koss 30 headphones are pretty poor audio quality. Bill
