  1. I absolutely love the extra ground coverage it gives me. Still playing with the settings, today it was running smooth at 18 sensitivity/4 recovery speed underwater and 23 sensitivity/4 recovery speed in the wet sand. After scoring 3 .925 peices doing up and downs on the shore line (found a rusty screw line not a coin line lol), I decided to continue them into the water. Low tide was half an hour away and dawn was slowly approaching. About 10 feet in, on my first line into the water, BAM! Solid 9, 2-4 inches down. The excitement start flowing through my veins. First scoop, Cartier platinum ring. 🤑 Gotta love that Fresh Drop Factor.

  2. Back in July we were speculating on a new Minelab trademark filing for Geo Sense PI. Looks like now we have an inkling what that was about and that it is related to the upcoming GPX 6000 model. Here are a couple tidbits gleaned from the full Codan 2020 Annual Report: JANUARY 2021 UPDATE - Minelab GPX 6000 Revealed! page 6: "Minelab will soon release an exciting new GPX® gold detector which will draw upon the best features of the GPX 5000™ and SDC 2300®." page 14: "Minelab will soon release a new GPX® detector which introduces an ease of use technology, GeoSense Pulse Induction, and will sit within the premium end of our gold detector product portfolio."

  3. The shape and angle of the target distorts the magnetic field which causes inaccurate pinpointing of the target. If the object is a spherical shape such as a BB or if a nail is in a vertical position then pinpointing will be fairly accurate. Hot rocks and mineralization may also cause some distortion. Soft iron has the most effect since it combines/concentrates and intensifies the magnetic lines of force. Gerry’s techniques above are about the best you can do to save on digging so many big holes. The attached drawing is an approximation of how the transmit and receive magnetic fields are distorted.

  4. Back in May we were speculating on the filing of a new Minelab trademark for "MF5" and what kind of detector that might mean. Well, Minelab quietly added the MF5 mine detector to the lineup. What makes this interesting is the MF5 employs the fold up housing originally developed for the F3 Compact mine detector, and later used on the SDC 2300 gold nugget detector. The Minelab MF5 introduces a new coil that features a round transmit coil combined with a EMI canceling figure 8 receive coil. The coil measures 7.5" x 10.6". Minelab MF5 metal detector Even more interesting is the MF5 is employing some sort of multifrequency hybrid technology. No doubt the reality is hidden under a layer of advertising catch words: "combining the advantages of Pulse Induction and Continuous Wave technologies" "Simultaneous Multi-Frequency Digital Metal Detection" "Four frequencies in the range 5 kHz to 75 kHz" This means the MF5 has at least some level of discrimination available: "DETECTION CAPABILITIES - The MF5 detects metal and conductive targets, including fine wires and carbon rods. It provides indications of ferrous and non-ferrous targets, carbon rods, and fine wires. The MF5 is able to detect targets in all types of soil, regardless of mineralized content, and can operate in environments of high electrical interference." Minelab MF5 Official Information Page MF5 Color Brochure Minelab MF5 User Guide MF5 TECH SPECIFICATIONS Key Technologies: Simultaneous Multi-Frequency Digital Metal Detection Coil: Transmit Coil: 269 x 191 mm (10.6" x 7.5") Monoloop | Receive Coil: Figure 8 Operating Frequencies: Four frequencies in the range 5 kHz to 75 kHz Output Power: < -30dBm Sensitivity: 1 to 5 Noise Cancel: Automatic, Operator initiated Ground Balance: Automatic, Operator initiated, Settings retained after switch off Target Identification: Ferrous / Non-Ferrous / Carbon Rods — Fine Wires MF5 GENERAL SPECIFICATIONS Volume Control: 1 to 9 Collapsed Size: 400 x 99 x 194 mm (15.7" x 3.9" x 7.6") Extended Size: 1615 x 191 x 237 mm (63.6" x 7.5" x 9.3") Weight, Operational: 2.8 kg (6.2 lb) with rechargeable NiMH C cell batteries Audio Output: Internal Speaker / MF5 Earset Earset: MF5 Earset Waterproof: Waterproof to 3 m / 10 ft (IP 68) Software Upgradeable: Yes Battery Compatibility: Rechargeable NiMH / Alkaline C cells Battery Life: 10 hours with NiMH batteries

  5. I've noticed the same thing with a variety of detectors in years past. A couple factors to consider, is the coil being used DD vs MONO or Concentric and the 2nd is the direction you are coming from when passing the target. I always try to circle my target while swinging back and forth. Also with some other detectors, I'll put detector in ALL METAL MODE and do a Size/Shape Imaging sweep. Kind of hard to explain, but as I sweep across the target many times and directions I pay attention to the response and many times, I can tell a longer signal from a round coin/ring one. The same thing can happen to a few coin detectors if the coin is on edge. Not sure if this is the answer you were looking for and hope this makes sense.

  6. A few things happening. The slower you swing a coil, the more time your coil is over a target and thus the "wider" (longer duration) a target signal sounds and the wider a target signal is, the less it can be confused for EMI. The faster you swing the detector, the less time the target is under the coil and so the target response you hear gets shorter until it becomes almost indistinguishable from EMI, so tiny targets get missed. Tiny nuggets already have a "narrow" sounding signal due to being small targets. So widening that signal out by slowing down your swing can make them stand enough to determine they are good targets. Re coil control: If your coil is angling up 1" at the ends of a swing and your detecting range for micro nuggets is only 3 or 4 inches, then you can be losing 25%-33% of your depth with just slightly bad coil control. It's easier to keep the coil flat at all points in the swing when going slower. Or, if the ground is uneven then you can keep the coil parallel to the surface much more accurately going slow. Also, the slower you go, the more you overlap swings and poke the coil into all possible areas around obstacles. To answer your second question: a large deep target can sound the same as a small shallow one in so much as they can both be faint and not very "wide" signals. But sometimes a shallow, small target will give a double blip as it passes over each straight section of the D's. whereas a deeper, faint target will be a single response at the center of the coil.

  7. Cashed out the last two peanut containers tonight (2019+2020). Total for all 4 was $703. This year I had a much higher percentage of quarters due to my outings this spring at a local rec. center. Last year's total was $145, and this year's total was $236 and still going. I included a picture of pre-Florida rejected coins and Florida rejected coins. Obviously, Florida soil is not kind to zinc pennies.

  9. I stick to JP's mantra: full range of motion swing (but slow) and strict coil control. The full range of motion coil swing has actually helped me greatly and I always try to remind myself of doing that. I have missed targets by not allowing the coil to sample enough ground to make the target stand out. Shallow targets give often a high/low response with double dip, whereas deep targets often give a low/high response with some lead time, meaning that the coil could already have passed the target) a the response is being generated. It's a SuperD, so the highest sensitivity are the two vertical lines on the coil (where the two receive D-loops are)

  10. Z, A slow and steady swing of any detectors coil, is a major factor in finding nuggets. If I’m swing on and old patch or a juicy looking spot, my coil is real slow. I’m not so much of a believer of a machine charging the ground, it’s giving the little extra time for your detector to send your ears then brain to comprehend as a target, with a slow swing. Your next slow coil target, give it a test, swing your coil over it faster...lots of times you won’t hear this target at your normal coil swing speed. Remember, this slow swing isn’t what you want to do Patch Hunting, your only looking for one shallow nugget when out hunting new ground. You find that one and back off a couple notches and slow your coil swing to help establish if you stumbled onto a patch. Your deep sounding nuggets sound vary and most will sound just like a little dink nugget...you always hope with each swing of your pick that it’s a deep one which will get louder as your hole gets deeper! Keep on swinging! LuckyLundy

  12. Probably pinpointing assistance, target on-screen visualization, and better ground balancing. I posted these as a guess when this Geosense logo was first registered, but worth revisiting since it still adds up. See this patent for "ease of use" regarding what sounds like target pinpointing and spatial visualization, maybe even with multiple targets on screen simultaneously. And this other patent to see how this might incorporate ground balancing too. Going one further, check out the patent just granted a few weeks ago. So with depth analysis, we might get some kind of 3D target in-ground visualization coming eventually assuming this stuff isn't just for their military machines? The filing date was early enough it could maybe make it into a 6000? Depending how accurate it is, that sort of thing can lead to a sort of target discrimination in places where certain trash tends to be shallow and nuggets tend to be deeper, or if it can provide some basic target geometry information. And the whole thing also makes me wonder if they might be trying for target size/geometry visualization too, though accuracy would really make the difference between that being useful and just being a curious gadget function. Totally off in the weeds guessing here though so it's moot.

Pretty good info thanks Steve, looks like a lot coming out for minelab, now I would love to incorporate the MDS-10 PI with GPR to see the contours of bedrock, look for those low spots where gold accumulates. There is a lot of new detectors coming out. Here is the link just for the countermine detectors. https://www.minelab.com/usa/countermine/detectors Also check out the F3 UXO - Multi Period Sensing technology into Minelab’s new BiPOLAR technology. 😳

  17. I'm no expert by any stretch of the imagination, but I have some experience with electromagnetic fields and interference. EMI has the potential to affect any electronic device. We live in a virtual soup of constant and intermittent EMF sources so electronic devices are being bombarded by EMI while emitting it as well. This is why electronics manufacturers go to great lengths to mitigate EMI into and produced by their devices. Without going too far down this rabbit hole, the short answer is yes both control box and coil and even the cable of metal detectors are all susceptible to EMI. The cable is shielded and control box uses electronic EMI control, so they are less susceptible to EMI disruption, but the coil is a giant electromagnetic antenna so it is the most affected by EMI.

  18. But the reason why these lores are *so* hard to dismiss (and so hard to apply critical thinking to) is that they are ALWAYS based on real names, dates, and events. Eg.: None of them ever started with "Once upon a time", eh ? They always cite a place, a historical event, a date, a few names of real people from history, etc.... And from THAT they weave a treasure story. So when it comes time to apply critical thinking, the average mind gets hung up on the "real" names, the "real" events, the "real" places, etc.... For example: Back before the internet, in the 1970s, a buddy of mine sent in a story to one of the Treasure magazines (so-as to get the $50 or $100 author-acceptance pay). He had some faded newspaper clippings, some actual dates and events (a gold strike in Nevada or AZ), some names and dates (that you could look up), etc.... And wove a fantasy tale of a "lost stagecoach loot" or "stolen military payroll" around the factoids. All of it was just made up fancy. We got a good laugh wondering if anyone ever actually went out looking for it. Not saying that all-such-tales are made-up fancy. They could be rooted in sincere telephone game, where no one along the daisy-train intended to deceive. But it only takes a few daisy-chain steps on the game before it's a room-sized treasure vault, with $1 million in gold bars, etc.... And you can NEVER put it to rest. Because the faithful will always point to the real names, dates, and events. The trouble is, that it DOESN'T MATTER if 99% of the story is true. Because if the 1% isn't true (that there's a treasure), then what does it matter that the other 99% is true ?

  19. Your detector basically turns long iron into a bar magnet. Wire, hairpins, nails... But you are also adding the loop affect on the bent end of the hair pin which also raises its phase shift. So it sounds like a good non-ferrous target. The pinpoint is what gives it away. A 90 degree pinpoint should have given it away. HH Mike

  21. Heck Strick, Your unit is probably out of warranty and about ready to be traded in for a new one with all the upgrades...and I know a dealer who can help. As for your older style battery system and getting the new Drop In. I have been told all batteries are going into the new detectors right now and now to expect any extras to be sold as Accessories for a couple to few more months. Thanks for allowing my staff/I to train you and Lisa as you both seemed to enjoy it and I know both found gold as well. Here is one of her smaller ones that Chris Ralph missed while Steve H was chatting with us. Good times.

  25. I have had no trouble with my Gold Kruzer running at 61kHz even in my basement or backyard. I don't crank up the sensitivity in either place but I don't even bother turning some detectors on anywhere near my house = Multi Kruzer and plenty of others. Simon, Nenad is telling you the truth. The 4"X7.5" stock DD coil that comes with the Gold Kruzer is a really hot coil. So is the 9"X5" DD accessory coil. In your mild dirt, the big elliptical concentric that comes stock would do really well. I am a big fan of the Gold Racer and Gold Kruzer. I just have to say that Micro, Fast and Boost modes on the Gold Kruzer along with waterproofing and some of the extra features take it to a hole different level. I have also had zero problems with coil knock when using the Gold Kruzer. I constantly had coil knock problems with the Gold Racer coils even running the sensitivity at moderate levels. Bigger aftermarket coils would be great for the Gold Kruzer when using it in mild to moderate ground.

  26. Might be another target dragging the signal over. Happens to me on my ib machines when there is a patch of rust with a target below. Take a plastic container and flip it so bottom is up. Put a silver dime below then scrape some rust on top and you may hear the target away from the center. Maybe this effects pi's too. For bobby pins I plucked about 15-20 of them out of local fresh water puddle with my Seahunter and 8" coil. They really sound good too hehe. You put a magnet on the bottom of your scoop? Helps catch them.

  29. Yes this happened to me a few times in the early 70's. Mama found my porn stash under the bed and it was what set up my career. After all, I tell many I'm in the Adult Entertainment business selling high end toys. These early magazines had me squeamish in bed a many sleepless nights. A boy my age was quite naive, so seeing such raw and natural images sent my brain into overload. I had no clue what the future would hold, but I feel it came out quite right. View these 2 early magazines and you'll notice some of the articles and headlines. 1st is GOLD by True West, 1969 Vol. 1, #1 and looking at the inside page of the articles are authors mostly long gone. But I give credit to them for allowing me to dream. If anyone knows of these names, it would be neat to get updates. 2nd magazine porn I used to drool over, Old West 1971 and just as incredible is an article about "Elk City Idaho" and just below that....perfect timing. "One Thanksgiving Day". Folks, I can't make this up any better. I go to my old stash and grab a couple and these are absolute on. The inside cover (I forgot to check the centerfold) is a full page ad from Jetco and their top detectors 50 yrs ago. The models of the detectors are catchy like many muscle cars of the day, GTO, Mustang, GTX, Treasure Hawk...didn't Minelab have a Treasure Hawk? So I ask you folks, show the rest of us your Treasure Porn that kept you dreamin, drooling and -master swinging.

  30. Did some relic hunting today with the intention of comparing some detectors (Deus, Tarsacci) but the Deus was on fire and besides keeping me from running a detector comparison test it also made it more difficult for me to proclaim 2020 a complete and total dumpster fire, but there is still another month to go.... Anyway, about a hour into the hunt, with the Deus connected to the 11" X35 coil and set at 12 khz with pitch tones and reactivity at about 2.5, I had found some keeper lead and brass. Then I happened upon a strong, 45- 47 signal. Thought it was likely can slaw but I was digging any repeatable non-ferrous signal. My handheld pinpointer indicated it was not deep, and I used my digger to come at it from a safe angle, just in case, and low and behold, out popped my first ever gold coin find - 1849 Open Wreath $1 Gold Piece. It was surreal. My digging partner thought I was kidding, but there it sat glimmering in daylight. Sent a text over to prove it since we were appropriately social distancing (something that comes naturally with this hobby). What a great initiation into the GC club. Needless to say, I kept swinging the Deus for the rest of the day except for a brief half-hearted attempted to see if I could get the Tarsacci going, but save for one so-so brass target, it was a Deus day. I swapped to my 9" round HF coil after the Tarsacci run and finshed up strong with some button, buckle, and bullet finds. One of my best detector single day outings ever in terms of both quantity and quality of relic finds. Only missing silver on this trip, but not complaining. Hopefully, this was a just a preview of what might be in store for 2021, as 2020 has been pretty much a lost year for many of us as far as detecting and other life pursuits go. The Tarsacci/Deus bake off will just have to wait for another day. Stay safe out there and happy hunting. CG

  31. Yes, I depth tested it both ways with DST on and off, and saw no difference in performance. In fact, I saw little if any difference in EMI either, so I ran mine with DST off most of the time. I think I read somewhere that the difference between on and off was very small. Lots of F-75/T2 info if you search Tom Dankowski's site.

  34. Is this an anology: does the wind affect the sail, the hull, or both? I think the answer to both questions is the same -- stronger effect on the sail but under certain circumstances (e.g the sail is furled) then the effect on the hull is noticeable. OK, the analogy isn't quite perfect, because who would ever (intentionally) operate a metal detector with the coil detached? However there have been situations here where people have reported interference when an electronic device is close the to control head but moving it away even a small distance improves things. As a side note, IMO there is a risk in asking for expert answers. Define 'expert'. If you leave it up to the individual then you will drive away people who are expert but also modest while at the same time keeping those who aren't expert but have unrealistic egos. In my case, for another analogy I (mis-)quote the old Holiday Inn Express commercial: "I'm not an expert, but I did read detectorprospector.com last night."

  43. Those are the Reebok/Converse ones I was talking about Dave that were pretty much the gold standard in detecting for a while. For some reason ever since Reebok bought them out, they have pressure points on my ankles, top of foot, or other spots. Like they are assembled different than when Converse made them and sometimes fabric gets bunched up or doubled over in some spots by accident during sewing. Or am I just having bad luck with them? I've bought 2 pairs since Reebok took over. They also get pretty torn up by cactus and rocks compared to the boots that use the smooth face, thicker leather and the foam/plastic thing above the sole ends up getting shredded on mine, which makes them too shabby to wear to like a dinner date or something (my boots are my full time footwear). I just want the perfect boot I guess, and it doesn't seem to exist.

  44. Our ground requires Difficult 99% of the time. In Normal things are a bit different signal wise over Difficult, so HY will give more ground signal and more conductive signal but the difference on big gold deep is less profound, whereas in Difficult there is a distinct difference between the two with the cross over being around the 9 to 20 gram range if the nugget is solid and deep, this is most obvious when the depth gets past 14+ inches. As an example I always detect in HY Difficult and get the bulk of the gold in that mode, if the size is up there and there is depth I’ll go over the same ground again in General in the hopes of a chunk. Nuggets found first pass in HY Difficult on a Virgin patch this year Pieces picked up at depth on 2nd pass using General Difficult (note some are small, this is because General runs at the same delay as HY so still has good sensitivity)

  45. Always detect back to your vehicle or start point, I am often amazed by the amount of good nuggets I find within 50 feet of where I park my 4x4. This 26 gram chunk was a good solid broad hit in HY Difficult yet when I checked it in General the signal was more subdued suggesting it was going to be less than 1/2 ounce, got the shock of my life when I threw it on the scales. I’d say the rough exterior made it more of a Fast Time constant target than the weight implied. So a 14 gram morning bonus’d out on a lucky find because I kept the motor running after a long hot session. 😎 Always a nice feeling when they won’t fit in your container. A 40 gram session is always greatly appreciated by the bookkeeper

  49. Had a good day out with the GPZ 7000. First target of the day was a hot rock 8 inches deep in cemented gravels. Next target was over a foot into the cemented gravels, but this time it was the kind of hot rock I like...the heavy, yellow kind. A half ounce day in the Arizona desert can be hard to come by these days, but it’s still out there.
