  1. Every time we get new detectors for the beach, we get the same question. "Will it find thin gold chains better?" It comes up so often I finally dug up an old post I can just point to whenever it comes up. Here you go. Gold Chains and Other Small Gold In Saltwater Here is a similar question that comes up a lot: Why Won't My Detector Find That Gold Chain? There seems to be a thought process that thinks somehow multifrequency overrides basic laws of physics, that some magic new processing is going to fix the issue. No. Not as long as conductivity is the measure. Once you understand this, you stop asking the question. Hopefully the article helps out with that.
  2. in this video we can see that the main transmitted signal is the same - Multi signal Equinox Park/Field/Gold = Deus-2 pr.1/2/3/4/8/12 - Equinox Beach and Deus-2 pr.5/9/11 signals are slightly different, but the upper frequencies are the same 24кГц - Equinox does not have a low-frequency signal, like deus-2 Deep and Diving program (Pr. 6/10)

  4. Here’s a topic for all you “Rocket Scientists” out there (and anyone else who’d like to chime in). I was having a discussion with another dealer. He felt that single frequency worked better because there’s a certain amount of performance loss with Multi. I was always of the opinion that Multi-Frequency was the best for most types of Metal Detecting. It allows you to hit ALL the targets that react better to certain kHz. Here’s an example from another hobby of mine (most of us have more than one). I shoot muzzle loading guns. The “Round Ball” type projectile that was used for hundreds of years performs best when shot out of a rifled barrel with a slow twist. Twist refers to the how many inches of flight it (the projectile) takes to make one revolution. The conical bullet came out during the Civil War and requires a faster twist. For modern muzzle loading rifles a slow twist would be 1 turn in 56, 60, 66, 70, etc. inches. For conicals, 32, 28, 24, etc. inches. In the 70s, one company came up with the idea of a “Compromise” twist; 1 tun in 48”. That way you only have to buy one gun. You can use Round Balls for Target shooting and Conicals for hunting. It shoots both “well”. Having said all that, does the Single Frequency work better than the Multi? Is there any kind of lack of performance or trade off having them (kHz) work simultaneously? Thanks!

  5. Hello everyone. Hope you all had a lovely Christmas. I've been doing pretty well with my nokta makro multi kruzer. I love it. I did some detecting in an old park today and found my first silver content silver. A 1929 Canadian dime. 80 percent silver 20 percent copper. Now I run my machine on 5 khz as this is supposed to give more depth for silver and copper etc I can't for the life of me remember what the dime was ringing in at but it rings it at 73 air tested. My question is it possible for that same dime to ring in at 30 on vdi and then obviously it'll change to 73 once out? I switched to disc at 55 and didn't really get many coins for the rest of the day. Found a 1897 young Vicky large cent that rang in at a choppy 30 to 75 and then 54 out of the ground. They're bronze. So far I've found 8 large cents numerous relics and the silver dime. Pretty happy. I know vdi is just a guide like. I'm thinking I may just dig anything that has a solid tone. I also dug 10 pull tabs and 5 bottle caps today haha
  6. I haven’t been in the market for a new detector for some time now. The VLF detectors hanging around here all have a fixed preset unknown “recovery speed” and only one detector has the option of changing out one coil with another of different frequency. Imagine my surprised when I read up on “Simultaneous Multi-Frequency”. After learning more about it, what really jumped out to me was the ability to adjust the “recovery speed” and the impact it had on target separation and search depth. Better yet “adjustable recovery speed” was now married to “preset unknown range of simultaneous multi-frequencies”. Could it get any better? What if we woke up Christmas morning to discover somebody wrote a few algorithms allowing us the pick and adjust for a known range simultaneous multi-frequencies (low, mid, high) to go along with our adjustable recovery speeds. We could design your own detecting search modes based on the ground conditions and targets we were actually detecting that moment. Maybe the cat is out of the bag but not in our Christmas Stocking yet.
  7. I'm wondering from those of you using detectors much longer than I have what would you say was the first 'smart' detector? Part of this question will be a definition of smart. I think of smart as being a detector that can do more than just 'respond' to a signal. It would do some processing. Certainly smart devices now have chips with algorithms. Would you define smart as a detector with a coin meter? Just wondering. Many definitions of smart devices now say it is a connected device. I'm not very 'smart' so that is why I am asking the question. Mitchel
  8. I mostly hunt in lakes and the bottoms are mostly all sand. A test on a sandy beach with the Equinox 800 and Xp Orx, both hit hard on a 14k 3.7 gram gold ring buried at 14". For mild ground I don't see a need for multi frequency. I do like the multiple frequencies on the Orx. Is there an advantage to multi frequency in mild ground?
  9. THIS !! All the people boo hooing will be in line to get one at that price point. It will also force the hand of ML with their price structure. ML raised their price on the 800 and NM absolutely crushed that price point. The Legend doesn't have to be better, just equal to turn the fortunes in their favor. ML and their arrogant "obsolete" charge is foolish. Obsolete by definition means no longer produced or used. Many detectorist and their single frequency machines are still out there making great finds and having fun. Furthermore, single frequency detectors are still being made and sold. NM build quality is far and away superior to the Nox detectors.
  10. I thought I was pretty damn good, but this technology has me beat. https://www.nbcnews.com/science/environment/mining-gap-companies-push-find-raw-materials-electric-vehicle-boom-rcna5077 Might be time to invest?
  11. Metal detectors often seem to have a 'Depth Gauge'. How is it calculated? Is it the strength (or inverse of it) of the amplitude of the return signal? So, for instance, everything else being equal, the 'deep' target would mean either a stronger target at greater depth or a weaker shallow target?
  12. While we're all abuzz with the announcement and advertised feature and performance characteristics of the XP Deus II, I'm wondering about tests that distinguish between detectors' target separation abilities. 'Word on the street' is that in trashy iron sites, the original Deus is still the best available. Presumably those reports are based upon in-field testing, which of course is the real proof. But the downside is, (AFAIK) these are qualitative observations, not quantitative. Subjectivity involved? Unfortunately, yes. We do have Monte's Nail Board Test for a special case -- iron nails near a single coin, all in the same plane and typically all on the surface of the ground. Add depth combined with some mineralization (burying the MNB) and you've included another real world dimension. But in the field, multiple nearby targets are seldom in the same plane. So you hopefully see the purpose of this post. Has anyone seen/tried other methods to better simulate actual in-field conditions to differentiate between competing detectors to best be able to handle trashy sites?
  13. I love coinshooting, and I'm often in my local parks or private permissions searching for clad and silver coins. But I noticed that when digging up shallow clad coins (3 inches or less), my AT Max with the stock coil would say the coin is 6 inches down. Sometimes, a surface coin would read at being 4 inches deep. I didn't think this was that big of a deal, b/c I could always pull out my F-Pulse and see if the assumed coin target was truly shallow or not. Also, the incorrect depth reading wasn't keeping me from digging a desired target. Tonight, I read: and http://www.fisherlab.com/hobby/davejohnson/SearchcoilfieldshapeApril2012.pdf Both of these mentioned anomolies or issues with DD coils and shallow targets. Is what I'm experiencing with my shallow coins and AT Max one of these anomolies? Or is there something else going on?
  14. speculation please. what does the future hold? what advancements might happen? keith southern are you out there?
  15. I got in a few hours of metal detecting yesteday with my AT Max, which included some time at a park and a few permissions (private homes). Nothing of note was found, although I continued to struggle with trying to find good targets in high-trash soil. Given how I'm using the Garrett AT Max, I know have two primary options for finding good targets (silver coins) in these types of conditions. First, get a smaller coil, like the 5x8. Second, start digging the trash targets to clear up the ground and reveal possible good targets that are being masked or otherwise "overshadowed" by all the bits of aluminum, nails and other garbage. The second approach is not a viable option for most places I hunt (parks and private permissions). Not only do I not have the time to implement that strategy, my body can't readily handle that much digging. Also, I'm pretty sure digging almost everything is bound to lead to the loss of any good graces I have with property owners and park maintenance crews. Ok, so that leaves the first option. But before I go that route, I have to concede the possibility of getting an Equinox. Based on my experience with my Vanquish, limited time on the Equinox 600 and experiences with my AT Max and Fisher F2, I'm confident that one of the advantages of getting an Equinox will be more stable VDIs and more accurate VDIs at depth. And right now, I think I can live with that. I understand that getting a solid signal (a good, repeatabe signal from both swings and in 2 directions) on a dime or quarter at 6+ inches in my mineralized soil isn't always realistic with the AT Max. But I know the AT Max is at least capable of getting a decent signal (a good, repeatable signal from at least 1 direction and in 1 swing). Put another way, I get how the AT Max may not get me the "dig me!" type of signal that an Equinox can, but I at least need it to get me the "take a closer look, please" signal. All of that to say that I'm thinking about how my AT Max's target separating ability and recovery speed limitations (using the stock coil) will compare to an Equinox 600 and a stock coil. I came to this realization when running the AT Max with only iron discrimination set at 35 resulted in information overload for me and notching out everything below 70 was likely leading me to completely miss "take a closer look, please" signals that might lead to silver coins, dimes or quarters. Therefore, I want to use Monte's Nail Board. I know it's not ideal, and I plan on using Steve's approach of using both the AT Max and Equinox 600 on real-world targets. But I think the Nail Board will offer quantitative data when comparing the AT Max and Equinox.I also plan on using it with my Fisher F2 and Vanquish 340 to help put things into perspective. So how do I go about doing this test? Here's my approach so far: Step 1: Create Monte's Nail Board and use it with a modern, clad dime and new nails. Step 2: For each of the 4 passes, I will give it a rating: Will Dig, Maybe Dig, Won't Dig. Step 3: I will set the sensitivities at either 50% or the highest possible given EMI Step 4: I will run each machine with zero discrimination and with enough notching so that it's only going to sound on dimes and quarters (and maybe copper pennies). Step 5: For the AT Max, I will also test it with iron discrimination set to 35. Step 6 (maybe): Run the test with the AT Max using both its stock and 5x8 coils. So here's my first real question: what changes or additions would you all make to my current approach? My second real question(s): what "base" setting should I use with the Equinox 600. I'm thinking Park 1 with recovery speed set at the highest setting (3?) and a small or moderate amount of iron bias. Should I also run some tests with the Equinox 600 in 4KHz mode? My third real question: would it be benefitical to modify Monte's Nail Board so that the nails are replaced by either clumps of aluminum or maybe pulltabs? A lot of my hunting is in parks and yards that are often littered with more aluminum trash than iron trash. Any insight is appreciated. Thanks!
  16. From what I can gather, higher frequency VLF detectors are more suited for smaller gold but ground mineralisation may be something to factor in. Would there be a “better” frequency for nuggets 1 gram and above in heavy ground? I’m not too concerned if I miss sub gram nuggets if there is a better suited frequency. The old Garrett Groundhog circuitry was legendary in this country…..I think it was around the 15 kHz mark. Is this frequency range a good starting point or do I need to consider other things such as better ground balancing capabilities or Garrett’s extra coil voltage. My Minelab PI units will be mainstay detectors but as mentioned in another post, I have ground littered in man made iron junk and the ground mineralisation is severe. There are plenty of nuggets in the 1 gram to 5 gram range (maybe bigger) but the iron signals are as dense as 5 per square metre 🤬 Thanks for any ideas.
  17. I’m a newbie and saving up to buy my 1st metal detector. Meanwhile I’m rockhounding a lot. I’m curious if folks have successfully applied portable ground penetrating radar (or other portable detecting devices) to predict likely location of crystal pockets in the hard rock, like in dolomite (for locating pockets of Herkimer Diamonds) or in granitic pegmatite (for locating pockets of gem tourmaline crystals) ? Any pointers would be appreciated.
  18. Norvic asked why I was so proud of a VLF when I own and have posted much success with the other higher end detectors. It was my post on rating the higher end Minelabs....so here goes. There are many factors to my craze and style of detecting, but my finds are the facts and not many people can compare, unless they too use the tools (detector) and hunt the style I do. I consider myself a gold hawg or gold pig. I chase it all in terrains flat or tall. Terrain - I live in the Northwestern state of Idaho and much of my detecting in the surround state of ID., is Oregon, Nevada and occasional Montana. For the most part, OR, MT and ID are pretty much the same with steep terrain mountainous rough country. A day of electronic prosecting and hiking in such states, is much harder on the body for a guy my age, heck it’s harder for anyone. Going to Arizona, Rye Patch and other Northern Nevada high desert areas is a treat for my body in more ways than one. Maybe that is why so many people detect there? It’s easy to drive and get to without walking…boy are most of us lazy? YES, including me at times, but not in my home state (backyard where I play). The ID, OR, MT mountains have steep ravines/canyons and the water is at the lowest point. Here is the many miles of hand placer workings, dredge tailing and hardrock mining ore dump piles. The gold I am chasing is the stuff the old timers missed. Pic below - This huge ore dump pile produced a few thousand dollars in Specimens. This is the not so steep side and we had to tie off with ropes on the other side. Half the targets would roll down the hill and need to be found during a break when we were at the bottom. The PI's can't see this time of gold. Trash - Trash is my treasure in a way.. as I know the site has not been hunted as hard. Trash is what most detectorists hate, and I too get that way on occasion, but I know if I'm patient, I'll eventually be rewarded. A big factor I run into is 100 to 150 yr old man made trash from the early prospectors. They left much of it on the hill, in the placer digs and tailing piles. Many of the small mining camps were right on or near their diggings and they just tossed the old food cans, tobacco/coffee tins and worn out leather boots with hundreds of nails and broken, picks/ax heads shovels aside. Pic below- In old tailing piles a lighter, faster, better ID detector is best. He who digs the most non ferrous targets in a day, get to smile all the way home. Pic below- is the 1 pound specimen after cleanup. Tools – Know your detector, its limitations, strong and weak points. Bigger deeper detector is great in flat terrain and areas with limited trash. Raw depth and power is amazing to have, when the target you dig a foot or so deep is not a sardine can. How about a shovel head at 2 feet or more? Think about it and what you do when digging 5 or 6 of those an hour with your big deep penetrating detector. What does your body have left in the tank? My lighter VLF is easier to swing in rough terrain, has better Iron and Target ID, is not as deep or powerful in trashy sites. It saves me time from digging unknown iron targets, it saves me energy from digging deep holes, it saves me energy from having to pack around a bigger bulky detector. The proper detector for the site is a must and in many cases my lighter, faster, better target Identification, sub $1000 investment is the right tool. Pic below - This golden oreo was recovered in old hand placer workings with my VLF. Having what I consider the best identification VLF gold detector on the market saves me time. Pic below - It was recovered at 16" with Minelab EQ-15" coil. Yes I'll be going back over this area with the new CoilTek NOX 15" round as it is even deeper. Gold Knowledge- This is confusing to so many people as they think gold is gold. Yes I too used to think the same way. Luckily I hunt a variety of gold producing locations and sites I like to detect and learn from. My many years of comparing/testing detectors at such sites has given my staff and I an understanding of gold, its characters, density and how the elusive Au responds to the varying detector models from the different manufactures. Many of the nugget photos being shared on social media in years past were dense solid gold pieces and they are beauties. That’s what the detector could easily respond to. In more recent years, the sizes of the nuggets became smaller and we started reading about and seeing some nice specimens. The newer GPX detectors with their advanced tuning and soil timings (Fine Gold) would outperform their older brothers (SD/GP’s) on smaller and courser gold, so when get to make more of those finds and share them. Most recent years has us using SDC-2300 and GPZ-7000’s. Again, the gold gets smaller and the amount of crystalline gold, wire gold, salt/pepper specimens are being unearthed with these detectors supersedes that of their older brothers the GPX series. Pic below - This softball sized specimen was found with a VLF and has multi ounces of gold. VLF picks it up deeper than many bigger detectors. Pic below - This beautiful 3" long quartz and gold specimen came from a trashy ore dump pile with a VLF. Pic blow- These quartz cocoon wire gold specimens bring a premium and come out of hard rock ore dump piles. Pic Below - The PI's don't see these rare pieces, the 7000 barley does on a select few. Pic below - I have a feeling the extra sensitivity of the new GPX-6000 will do even better. Proof – The facts are in the vault at the bank. I own beautiful specimens pieces recovered with detectors and have tested many on a variety of detectors. I have gold finds that are multi ounce pieces and they contain 2 or 3 ounces of gold in them, but for some reason an SD or GP don’t see them, even less than an inch. I also have such pieces my GPX 5000 does not see, but my GPZ-7000 does. What is most amazing, is I have pieces of gold with multi ounces of metal and even the ZED has issues or can barely respond an inch or two away. If this is the case, then why do I have these find gold pieces of art? I’ve taken the time to test and learn my detector tools and have found a certain trusty VLF sees them all, can ID them all, is lighter in weight and so I get to hunt longer, saves me energy since I don’t dig as deep for unwanted targets. Pic below - This specimen came from dredge tailing and the speckled pieces like this get missed by most PI's. Pic below- Over $800 in gold in this 3 ounce specimen and my VLF does better than my GPX-5000 and my SDC-2300. The SDC goes deeper than the GPX. You better know your gold and your detectors capabilities or lack of. Pic below - This 3 ounce specimen was found in trashy hand workings. I actually had a GPZ-7000 here for a couple hours and gave up because of the amount of item trash. A GPX-5000 with DD coil run with DISC mode would be better than my GPZ, but then again my NOX does even better. Better target identification of my NOX, is most important at the site this 3+ oz'er came from. GPX-6000 – A new tool and one that has Gerry very very excited. Now we are about to get a revolution of Geo Sensing Technology with PI power and capabilities for a wider variety of gold textures, densities, characters and sizes. Minelab (and their track record) is even telling us some of such capabilities and so I and a few of the guys who do not like to miss gold, are getting ourselves prepared, getting our old sites, lined up and making sure we are going to take advantage of the stragglers. Remember when the SDC-2300 and GPZ-7000 came out and all the slow response from the majority. You folks missed the opportunity of a lot of gold. My guys and I were killing it in NV and AZ on those so called worked out sites. Was it a gamble to spend that kind of money? If that’s what you love/enjoy and if you have a good track record with Minelab, it’s bet I’ll take most every time. I don’t lose detector bets very often. Pic below- This stunning collectible specimen was found by my brother with his SDC-2300. It came from a place he had previous hunted and found gold with his GPX-5000. The 5000 does not even whisper on it. Minelab claims the GPX-6000 is more sensitive than the SDC-2300 & GPZ-7000. I can't wait to use the GPX-6000 at the site and many others. Hopefully this story and the pics I shared will help educate some of you on how the different detector technologies produce more gold. I realize it's hard to put down your old reliable detector as it has probably and hopefully served you well. If your sites are getting thin of targets and or gold, just maybe a new detector can put the smile back on your face? I'll go back to this simple statement I have said below in other posts and it is the absolute truth. You can't find what your detector don't see. PS - I’ll be honest though, for me it’s the lighter weight, better ergonomics, not being tethered in a harness and User Friendly that has me sold. The extra gold my new GPX-6000 is going to find, is a bonus. PPS – I’m just as eager to test the GPX-6000 with some of my gold and see how much better/worse it does than my GPX, SDC and GPZ. (I'm educating myself). PPPS – I still feel there will be a place for my VLF, as it’s lighter, and have better target ID. See you in the gold field, where the most knowledge is learned.

  19. After the good new I realized when tested a few days ago my machine after It drowned and I've succesfully reanimated It.... Now the horrible gasket Is fighting to stay out of the housing against any kind of attempt😒. So I'm in the middle of a headache manutention session with scarce results. That's the Mood guys😑
  20. So Im curious... with Makro/Nokta we saw a ton of You Tube videos on the Kruzer in various settings. Even Dilek posted on the machine on the forums before it came out. Even the AT Max we say a little here and there on the unit. Where was the early info on the Equinox? I know there was/is a "gag order" in place, and boy did they do a good job... not a word from anyone hardly! But when does the gag order lift? 1 year, 10 years Never? I'm interested in the "seasoned" testers that were able to use early models. These early thoughts to me are a real gem on what was changed, improved, altered. Any ideas?
  21. 99% of my detecting is done on central Florida beaches. Since it’s impossible to establish a well stocked test garden at a public beach, I sorta brought the beach home with me and developed my own private beach garden! I cut slots in two large empty chlorine tablet buckets at various depths as shown from 2 -16 inches. I then filled one with New Smyrna Beach sand and the other with soil...for the few times I land hunt around here. I embedded numerous examples of ferrous and non ferrous targets into paint stirring sticks. I also have several blank sticks I use for gold and silver jewelry as well as artifacts that I don’t want permanently attached to a stick. I then insert the target(s) in the slots, each at its desired depth, and start scanning. This allows me to rapidly change the targets, depth and relative position of each. I can now test for sensitivity at depth as well as separation of ferrous and non-ferrous targets in a variety of scenarios using actual beach sand where I do my detecting. If I want to test in wet salt sand, I just soak the bucket sand with authentic sea water that I also brought home from New Smyrna Beach...and the Atlantic Ocean never even missed it. 😉 Works for me.....
  22. I'm looking for a Compass metal detector catalog that includes the Compass Gold Scanner, and Compass Gold Scanner Pro models. The full line catalog, and this would be about 1990-1992 or thereabouts. I'm adding a few key older metal detector catalogs to the Downloads Area to provide basic info on older models. I do not need a ton of catalogs, just key years where major model changes occur, as things moved slower back then. If the catalog was in pdf format that even better, but Googling only turns up a couple older catalogs, nothing I can find covering the Gold Scanner era. I am more than happy to pay for a print version if need be, so I can scan into pdf and put up for people to download. Thanks in advance for any help. Me and my Compass Gold Scanner, back around 1990:
  23. This was mentioned by geof_junk in another thread and had a little Google. Found this https://www.phys.k-state.edu/reu2011/nnorvell/Metal_Detector_Research.html I don’t really understand the technical side of metal detectors. Does this have any application to current day detectors? Will it help cancel out ground noise more? Will the current crossing/not crossing the ‘bridge’ tell you something about what is under one of the receive coils. Although I don’t understand it, I am amazed and a little in awe of those that do 👍
  24. This is a topic relevant to every(?) form of detecting -- ground coverage. I'll list several questions concerns I've had but any replies of course aren't limited to these, nor do they need to address any of them. Just tossing out some ideas to prompt further discussion. 1) What methods and efforts do you apply to ensure full ground coverage in the cases where that is one of your goals? 2) Is your sweep a straight line path or an arc? 3) How long is your sweep? 4) How much do you overlap consecutive sweeps in the direction you walk? 5) How much do you overlap side-to-side swings when following parallel paths (e.g. when walking two side-by-side swaths in the same direction how much does the left end of one path overlap the right end of the next path or vice-versa)? 6) Have you ever measured your coverage? How well do detectors with GPS (e.g. Minelab GPZ-7000 and Minelab CTX-3030) monitor ground coverage to this detail? Have you used other devices to measure ground coverage. E.g. I can imagine a drone with camera could provide useful data. Are there smartphones app that would help quantify coverage?
