  1. Anybody have any real field reports (or tests) on the Coiltek 11" ROUND coil? I am looking to find out how much deeper it is over the stock 8" SDC coil. So far, I have seen one Youtube video that was inconclusive. Seems like it increases depth by a slight amount but decreases sensitivity to the super tiny bits...1 grain or less. Even an extra 1 inch depth on those prickly specimen nuggets, it would be worth buying for me. (Unless I can get one of those new 10x9" or 12" Round X-Coils for the GPZ.) Thanks, Don
  2. I have been waiting for an updated SDC as well. Or a small coil for the GPZ! -Don
  3. If you are getting 9" in the dirt on a 2.5 gram nugget with the 14x9 coil then your detector is working fine. What timing are you using? -Don
  4. 9 inches air test on a 2.5 gram piece is typical using the 14x9 coil. I only get 11 inches on a 4.5 gram piece using a 12" round EVO in Fine Gold. Get the same on the GPZ 7000 in Difficult. As Steve said, a PI will lose less of this depth in mineralized ground over a VLF. I can only get about 3-4 inches maximum on a VLF in my hot ground. The PI will punch much deeper, if 11" in air, I would probably get 9-10"+ in the ground. The air test is always the best case scenario for depth for all the people that think air tests are not important. They also tell you if your machine is working correctly vs other machines on the same settings. ( or for comparing depth increases on coils) -Don
  5. Thanks for the responses guys, I am going to try another GPZ 7000 and test out the Salt Mode, Semi-Auto Ground Balance, and Locate Patch. I won't know if it works here until I try it for myself. Anyway, I plan on eventually moving down to Nevada and I know the GPZ will be an advantage there. I am tired of my small area of gold detecting here in Washington State. Also, I do miss getting some of the strange specimen pieces my GPX-5000 doesn't see. It only accounts for about 5-10% of the gold here but they were fun and interesting to find. My SDC would see some of these specimens but I sold that a while back. -Don
  6. I used the GPZ 7000 in the Summer of 2016 (with yellow ferrite ring) but it had so much ground feedback in my detecting area that I sold it. I found that the ground noise on the GPZ was masking targets over the GPX-5000 running in fine or enhance gold timings. (Damp & salty highly mineralized ground.) Question: Has the latest software update with Locate Patch & Semi-Auto Ground balance helped significantly to handle this type of bad ground feedback? I am considering buying another GPZ 7000 this Summer to try again. Also, I found that the 5000 can match or beat the 7000 on larger chunky gold targets when running the larger coils. (And of course, the GPZ was superior on some specimen gold types vs the 5000.) Here is an air test on a 3 ounce wire gold & quartz nugget below. The 7000 was at maximum sensitivity of 20 with the stock 14" GPZ Coil. (I didn't own the 19" GPZ coil to try in this test.) I mostly ran in Difficult/General or Difficult/High Yield as Normal mode was impossible here, too much ground noise! 3 Ounce Wire Gold Nugget: (air test) GPZ 7000: Difficult/General: 18" Difficult/HY: 18" Difficult/X-Deep: 16" Normal/General: 21" Normal/HY: 23" Normal/X-Deep: 20" Severe: 15" GPX 5000: Fine Gold w/12" NF Round EVO coil: 17" Normal w/12" NF Round EVO coil: 21" Fine Gold w/15" NF Round EVO coil: 18" Normal w/15" NF Round EVO coil: 23" Fine Gold w/19" NF Round EVO coil: 20" Normal w/19" NF Round EVO coil: 25" Fine Gold w/25" NF Round Advantage coil: 20" Normal w/25" NF Round Advantage coil: 26" -Don
  7. Are you able to put a bigger coil on it? Looks Good. -Don
  8. Nice Nugget! Looks like the GPZ found it at almost 2 feet depth based off the photo. (And with the standard 14" Coil) -Don
  9. I just received back a repaired GPX-5000 from Detector Center/Minelab repair. The function select knob was failing. It was replaced very quickly and sent back in good working order. Good customer service! -Don
  10. I look forward to seeing that special gold in person. I will be there on Saturday. -Don
  11. Hello Dave, Did you already go over this area with your GPZ 7000 previously and it missed this gold? SDC only gold? (Looks like a big chunk that the GPZ would see.) -Don
  12. I was told by an experienced detectorist that it has similar depth as the 15" Round EVO coil but a lot more ground coverage. I might try one later this year. -Don
  13. Has anybody else tried this NEW 24x12 EVO coil? It seems like there are not a lot of people using it. (not much information out there) -Don
  14. The GPZ & SDC can see types of gold the 4500 & 5000 cannot detect. It would be interesting to know if your modified 4500 can see these types of gold. I read on Woody's site that the mod allows detection of this gold on the 4500/5000 by extending the frequency range. I have gold pieces that scream on the GPZ & SDC but don't make a peep on my standard unmodified GPX-5000 no matter what timing or coil is used. -Don
  15. We have hot ground in Washington State. (Liberty Area Basalt, been detecting since 2008) Thanks, Don Newell
  16. What settings do you guys use to hear the "missed beats" or pauses in tone on the GPZ? -Don
  17. Thanks for the coil tests Steve! I have the 6" smart coil for trashy areas. I am new to the CTX but I have found that maxing out the sensitivity at 30 gains a lot of depth compared to Auto +3. Using the 6" Smart coil, I get about 6 inches in Auto +3 but 10 inches in Sens 30 on a dime. -Don
  18. Hello Steve, Have you had a chance to compare the 6" Smart Coil to the Coiltek elliptical coil yet? Thanks, Don
  19. I spoke to somebody that is involved with Minelab coil testing. He said there is a small GPZ coil in the works. We might get some details in the next 1-2 months. I hope this is true because in my terrain and inside the local mine tunnels a small coil is needed before the bigger ones.
  20. Hello Merton, I am a coin & jewelry hunter with the CTX. Relics are not really worth my time unless made of precious metals. (I don't live on the East Coast where there are good historical relics to dig.) I would buy the Deus for plucking old coins from the trash as you say. I will order Andy's book on the Deus and see what I can learn. I am looking at the 9" Deus Coil or waiting for the new elliptical coil. (V4) -Don
  21. Thanks for the response Steve. I might pick one up when the V4 9x5 coil comes out for those heavy trash situations. I know there are a lot of people out there that love the Deus. For now, I am still learning the CTX. (I bought Andy's book) -Don
  22. Steve, How is the XP Deus working for you? Is it really a worthwile addition for a CTX owner with small 6" smart coil for unmasking? I tried the Nokta Relic. I wanted to like it but too many false signals had me digging tons of trash. Some iron gives high signals even just 2 inches down in my dirt, out of the hole it goes low signal. I don't have time for that. Coins go into the upper nineties for target ID so a nail & coin look the same. I understand it's different in other States with milder soil. I finally bought a new CTX instead. These machines work here! I never seem to be able to get away from a Minelab. (Fisher has been good as well. Accurate target ID) -Don
  23. I would like to hear about how the field tests of the 14x9 Evo coil go. I saw 2 people on an Australian forum say they are noisy. One may have just had a bad coil. I have been thinking about picking one up over the 12" round.
  24. Dilek emailed me that the Gold Racer coils work on the AU Gold Finder. However, the little GR19 coil I received today was defective straight out of the box. Super noisy with intermittent overloads when held in air. Yuck! I think something is wrong with the connector cable wiring. When I hook up my 5" round coil in the same spot, everything goes back to normal. (Quiet operation) Nokta/Makro needs to get their act together on quality control. -Don
  25. Hello Steve, I have the AU Gold Finder (Gold Racer Circuit) and have been using it inside a large drift mine in areas that have been hunted with every Minelab (including the SDC) except the GPZ 7000. The AU Gold Finder has been finding a lot of little nuggets in cracks where bedrock and soil is hot using the 5" round coil. I use ALL METAL and it works ok but some tiring ground feedback from variable ground. My very favorite setting is SINGLE TONE in DISC with very little ground noise. In 2 Tone the unit will make pops and clicks (or broken signals) in the hot ground on tiniest of pickers. But in single tone, I am getting the tiniest nugget signals loud & clear. (Use Disc Filter on LOW of 5 or sometimes ZERO if scanning a cleaned off crack for the strongest signal, MAXIMUM sensitivity of 10, IMASK at 2-3 in my ground, Almost maximum volume.) Give it a try if your prototype version has single tone. I usually operate in "Disc 2 Deep" when I am using single tone. It has been a great addition to get every last picker. The only problem is that my Whites TRX pinpointer cannot get these tiny nuggets and it gets time consuming looking for that tiny piece(s) stuck in a bedrock crack. I have the new small 4" wide elliptical coil on order. (waiting...) -Don
