    o I finally have some production models of the New dual adjustment bungee I designed. I think I am going to call this one the QWEEGLE. Sort of a combination of Quick Bungee and Double for Double adjustment. I know a lot of you use your own harness, which in a lot of instances is a modified Camel Back. Camel Backs are great because they provide hydration and give you a great place to hook a bungee cord up to. Well I have thought long and hard about now to improve the QWEEGEE bungee which allowed you to adjust the length of the bungee where it attached to the rod. The BOOMERANG bungee which I also invented allowed you to adjust the length of the bungee at the "D" ring. The big issue with the QWEEGEE, was that you could only detach the bungee at the "D" ring, so when you laid your detector down the bungee was lying in the dirt. There was no way to detach the bungee from the shaft of the detector. Also where the bungee snapped onto the "D" ring it was pretty clumsy to get it on and off. I wear gloves, and when you wear gloves, small pieces of plastic are hard to deal with. So here was my challenge. 1. Design a bungee that could be adjusted with at the "D" ring or where the bungee attached to the rod. 2. Design a bungee that could easily be detached from the detector. or the "D" ring. 3. Make the process of detaching the bungee really easy and effortless. 4. Provide an optional attachment ring that would be similar to a "D" ring but be more durable, easier to attach to, allow the user to stitch it onto their own harness, and not turn around in the webbing you use to attach it. Standard "D" rings, always manage to wiggle around in the webbing and end up looking just like this "D" running vertical instead of like a U where the curved part of the "D" stays at the bottom. First part: Easy on and off attachment snap that attaches to "D" ring. Nice and hefty and durable. A thumb tab, to allow you to remove the bungee from the adjustment groove using one hand. Second Picture: Adjustment groove in snap. Lift or lower your detector while the bungee is out of the adjustment groove to find the right length, give a slight tug down to seat the bungee in the groove and lock the bungee to a perfect length for detecting comfort. SHAFT ATTACHMENT ADJUSTMENT Point. Long non-slip strap that will accommodate all known detector shafts, even the Garret ATX Deep Seeker that has a rod the size of a baseball bat. • Easily attach or detach bungee by pulling the bungee in or out of the SLIDE SLOT. Picture 3 • Easily adjust the length of the bungee by lifting your detector up or down, and then tugging the bungee up into the adjustment groove when you find the proper length. Picture 4 • Use the shaft attachment point only as an attachment point, and don't use the adjustment feature. Simply put the loop at the end on the bungee onto the shaft attachment point. Then you can use the snap at the "D" ring to make adjustments Picture 5 PICTURE 3 PICTURE 4 PICTURE 5 Then we have the optional non-slip "O" ring that I designed . Supplied with a piece of webbing for you to attach to your favorite harness system. I designed all of these pieces. I had to have injection molds made (not cheap) and had the parts molded out of Nyglass, which is a darn near bulletproof material. That "O" ring is 2 1/4 inside diameter. A blind drunk monkey could attach the snap to this "O" ring without ever worrying about having to see it. So I would love to hear your input. I have just 10 from the first production run. The rest will be sent by boat. Only the plastic parts and the strap are being shipped, we assemble the parts with the bungee here in Henderson. Some things are OK to have made in China, but bungee cord is not one of them. We use a very expensive high quality marine grade bungee. Doc

    I understand where you're coming from. Auto tracking systems can have their advantages for inexperienced operators, or, as you said in"variable ground". They also had disadvantages, at least in some of the earlier systems. Around the late 1990's, well known detector designer Dave Johnson designed the Lobo Super Trac for Tesoro, or Lobo ST as it's most widely known. It had a very good ground tracking/balance system which was great for beginners. It had a shortcoming though. The tracking system could not be locked to the current ground phase when a target was found. As the user would wiggle the coil back and forth to further analyze the signal, the GB system continued tracking. At times it could actually track out (eliminate) the target signal as bad ground. It could/can be mitigated by making wider sweeps of the coil to let the tracking system read the surrounding soil matrix and adjust to that and not read the target as bad ground. Fast forward a year or two. Mr. Johnson, now working for Whites Electronics was in the process of designing two widely popular models for them, the GMT and MXT. He obviously was aware of the shortcomings of the Lobo ST tracking system. He made one huge addition to the whites models, the ability to lock the current ground phase in the tracking system when the user had a potential target. Once locked, the operator can move the coil back and forth to analyze the target with no worry of it being "tracked out" as bad ground. He also added the option to manually ground balance, and the very nice Ground Grab system which at the push of a button adjusts the ground phase of the machine to the ground matrix under the coil, as the computer constantly monitors the ground phase conditions. A great bunch of options at the time! Mr. Johnson has gotten away from auto ground tracking/adjusting systems for the most part at First Texas now. Most of their current machines employ the "Ground Grab" system, or the Ground Grab, plus a manual option most are familiar with. The newer machines of most other brands employ a variety of the GB options including tracking which is quite common now. They seem to work well. I still have a fondness for the GMT's options which are now nearly two decades old. As to the GB2. It's another one of Dave Johnson's excellent designs, and an all-time classic. I don't think I'd change a thing with that one! Sorry for the long winded post.

    Guess what I got to pick up today thanks to Brian at A.M.D. in Anch. And yes I picked up some new killer gels to finish off the last month & a half, but that not it ….. The NOX 6" ( that I and a lot of folks have been & still are waiting for ) came in and I was more then happy to spend 4hrs rd. trip ( this time of yr. ) when Brain gave me the call. Thank you Alaska Mining & Diving !!!!!!!!!!

    You can cheat with an auto tracking machine if you want to up the GB a bit by ground balancing but only lowering you Coil down to 4 or 5 inches off the ground or even higher and you can make it go the other way by only raising it by about 3 inches from the ground and by letting the coil linger on the ground, So you can off set the GB to suit although you have little control by how much, I know with one pump of the coil it will be slightly negative and at two pumps it will be slightly positive and by the third pump it will be more so making a bit more noise as you lower the coil, but as a rule it always ground balances with 2 pumps of the coil or if I have had the tracking locked If I press and release the ground grab it update to the current GB setting that the detector see's without have to pump the coil and it only takes about half a second or less for it to GB it's self, Manual GB is handy for those who like to tweak things but if you only have Auto track and Lock you can imitate it to a fair degree.

    That's what I was indicating a Gold Bug 2 version 2 should have, nobody would take away the option to manually ground balance, but it sure is nice to have Auto when you want it, especially in very variable ground. There is always room for improvement on any detector which is why I was saying it's nuts they haven't come out with an improved version after all these years. Fisher added the Ground Grab feature on the Gold Bug Pro, I like it, takes seconds to do but they left the manual controls to manually adjust the ground balance. I don't think the GBP was meant to be the replacement for the GB2, it was just more stable in a lot of ground with its lower frequency and was capable of more types of detecting so it was there to open up a bigger market than the GB2 had. I will admit the more I use it the more I like it. It appears to have a really accurate VDI number system too in discriminate mode.

    Thank you Brian. This was my view from work today from the new house I am working on. Note the steam ship to the left of the container 106 year old TSS Earnslaw. A coal powered steam ship. Use to ply the lake as transport for people, sheep, cattle & cargo. Now does tourist trips. The TSS Earnslaw tied up in Queenstown bay Approaching Walter Peak Station wharf. Here you go on a farm yard tour, feed the animals watch sheep dogs rounding up sheep & bringing them into the yard for shearing & of course sheep shearing. Then it's off to the building for a tea or coffee & a bite to eat. My son Stefan & grandson Luka & Stefan's partner, Patience. Not the mother of Luka. Looking out from the table to the gold side of the lake. No gold at all on Walter Peak Station side of the lake. TSS Earnslaw at the Walter Peak Station wharf My grandson, Luka, down in the engine room Stefan, my second eldest son. With the beanie on. The best value for money tourist thing to do by far. We always recommend it.? Cheers JW

    I finally got my hands on an 800. I'm a thrifty kinda guy so I waited until the inventory built up and while I did I was using the 600 to become familiar. Traded the 600 when I was done with it for an AT Pro, 3 AT coils, and Z-Link system plus $200. I played around with the AT Pro for 2 weeks before selling it for more than enough to buy a used, complete 800 for $700. I'll be honest with you guys. I've used a lot of machines, including an AT Pro before I had this AT Pro. I had the first one briefly with the big Nel 14" coil. It didn't leave an impression on me the first time. It did this time. This time I saw what all the fuss was about. It was a really fun machine to use. Very well behaved, but plenty deep, and I found a lot of nice things with it in that short time. I hated to give it up. But I digress. In any event, now that I have the fully loaded Equinox 800 and the V3i I'm gearing up to put on a very detailed head to head comparison. I like things very structured, scientific, and complete. One area I already see a blowout coming is the Equinox recovery speed quite noticeably outpaces the V3i. But there will be areas I expect the V3i to shine. With either one you get a lot of detector and I'm pretty satisfied that they can handle most any scenario I'm going to run into, especially now that I'm starting to put together a pretty good coil lineup for the V3i. If anyone has any specific areas of comparison you'd like to see, feel free to offer suggestions.

    Thanks, I came to thinking/wishing they would sort out the ground issues when I was testing my coils and someone posted about how far their machine could air test a coke can, Well the coke cans over here are smaller at 330mils and when I did his test I Dare not publish my results because it would of started a war, even more so when I used my favourite coil, But I thought if I could get that depth then I would need a JCB and leave the pick at home, As it is I have a coil that can see Cans at up to 3 feet and maybe a bit more in the ground but it Air Tests at ridiculous distances, I have always thought if I loose 70% of that distance in the ground then I am still going to be digging 2 or 3 feet holes on a coke can, Perish the thought ?. Good ground balancing is one thing and the MXT has the best GB ever made but that is only a small part of the story because as we know the ground minerals can just destroy a detectors depth, but regardless of the GB system until a detector can wipe out those mineral then we are not going to see any improvements in depth, Because they have the same effect as Headlights in the Fog and when it gets too bad we have to turn down the gain so it can see, A bit like switching from High beam to low beam in the fog, We have detectors with multi frequencies that can ID a coin in a bucket of Nails with maga sweep speed and even faster separation speeds yet we still don't have a VLF that can see through the Mineral Soup that we face on a daily bases. We have everything but the Ability to see whats down there.

    The lower the recovery speed, the more knock sensitivity you will encounter. Very critical and those seeking "more depth" by lowering recovery speed will be fighting themselves in bad ground. Ground balance does also make a difference as Chase notes above. And sensitivity also. With both the Gold Monster and Equinox I see people making the machine compete with itself. With all VLF detectors the basic idea it to run settings as hot as possible while still having stable performance. Then you can compare one machine to another. Both Gold Monster and Equinox when configured with stable settings will compare quite well with competing models. However, people air test the units with all settings at max, and then think they are losing performance by using stable settings. They then push the settings on the ground higher so as to "not lose depth". And then have issues with noise from various sources. Now that's all fine if you don't mind the noise and are willing to deal with it, and some can. Both the Gold Monster and Equinox purposely give you access to the highest gain levels possible. These maximum settings can only get quiet operation in mild ground, and maybe not even there. Pushing beyond that will create noise from ground, coils, hot rocks, EMI, etc. Each person faces the choice of tuning the machine for quiet, stable operation, by adjusting settings to get just that, or whether to go as hot as possible. It is location specific, so canned settings from one place may not work in another. You have to learn how the controls interact and adjust accordingly. In the end, whether a unit is noisy or not is up to the operator. Expecting quiet operation from a Gold Monster or Equinox running them as hot as possible is just not realistic under most circumstances. Even default settings may be too hot. Case in point. I was testing at a spot where a Gold Bug Pro would run stable at full sensitivity. The Gold Monster in the same place exhibited coil knock sensitivity and related ground noise at full sensitivity. Bad, right? Well no, since the Gold Monster at about a 50-60% sensitivity setting was already matching or exceeding what the Gold Bug Pro could do on a half gram nugget. I could run both machines stable and the Monster easily was beating the Pro. Pushing sensitivity higher on the Monster in theory gets even more of an edge but at the cost of introducing noise into the equation. All the above assumes a properly working detector / coil and not everyone has that combination. This in turn introduces wild cards into internet discussions. So far this year I have had no real desire to fire up my Gold Monster to hunt gold. My Equinox is proving quite satisfactory in that regard. I don't obsess over splitting hairs over which VLF detector is best when a GPZ 7000 accounts for over 90% of my detecting hours when hunting gold nuggets. That being the case I admit to using the Equinox just as much for the fact as it is new and intriguing as anything else. I am quite confident I can find gold with the detector and that's good enough for me. It's a different beast than most nugget hunters are used to however so just because I am happy is no indication others will be.

    Hi Simon, The manual ground balance is a no brainer & actually an advantage. It gives you an edge if used properly & I don't know why people struggle with it. Once learnt, which is not hard. Hell, if I can do it a monkey could do it. Are we now living in a world where people just have to have everything so laid on & simple? The GB2 has proved itself beyond its years....& still continues to do so. It was "improved", I guess, with the release of the "new" gold bug & gold bug pro models. But not at the 71 khz. Dont you have two of them?? But you thought they were no good because you were struggling to find gold with them. It is just a matter of getting to know a detector. Not buying the next latest thinking that will improve things. You do still have to walk over the gold. You found a piece with your Gold bug Pro & then you changed your mind about it. Oh...not so bad after all. You need to learn to walk before you run. Buying every detector isn't really going to make the gold come any quicker or easier. That is a false economy. Successful detecting will always come down to skill level of the operator & knowing how to get the best out of their gear. I believe you can put a crap detector in the hands of a very skilled & knowledgeable operator & they will do better than a novice with the best detector. The GB2 will go down in history as a legend of a detector. It does excell at the task it was made for. As we know. No one detector does it all, but that comes down to having a Pulse induction, a high frequency VLF & maybe a Zed. I guess what I am trying to say is...learn the detectors you have instead of jumping straight on to the next latest release high frequency VLF. Go out & get detecting. Show us the GOLD. I am late for work now. Good luck out there. JW

    What a world of difference of the level of service in the new Pa. location from Florida.I was having s lot of static and signal breakup on the wireless Avantree phones I had for my 600.I first thought it was the phones but alter testing a second pair it was clear it was the machine.Contacted the service center and they sent me a shipping label for UPS so it was no cost to me.I sent it in on a Wed. and they had it on the bench on Friday,They could not find the issue at first,so Jamie went out a got a pair of non-minelab phones and had the same issue I had.He replaced the control pod and I had it back the next Wed. .The difference from when I sent my CTX to Florida was night and day.What a great change for the better!!

    Thats the unfortunate reality of the internet. It’s soeasy for people to post vids and forum posts of things they perceive as problematic before they have taken the time to really learn the machine’s character and capabilities.

    Somebody once said beware of the man with only One Gun because he proberly knows how to use it, Detectors are the same, Although my VLF is a new older design I never worry about what others are using or how much more theirs cost, I have seen the Gold others have found and I know what I have found and I have used it from the UK to Gympie QLD and the GT, So a person needs to trust the machine and if they know it well enough then most of all they need to trust them selves, All the modern Hi frequency machine are very cool and the ones you have can a will do the deed if you let them teach you, forget your bad habits from past machines, If prospecting is your thing then work on that mode first and watch Chris Ralph's videos over and over til it sinks in. He's a good teacher not only does he tell you what things do but how and why. Too many videos tell you how to change things but they don't tell you why or the cause and effect involved and the manuals are not much chop either, this is why doing your own testing is important when you don't have others around or close by to help.

    Many folks chop and change machines search for that magic machine but it does not exist, The machine a person should stick with is the model they had the most success with which is why I won't change my VLF, some folks have bought and sold at leased 10 maybe more machines this past year and they are back to square one, If people would finesse their skills with the machine that they were most successful with then they would not need to keep wasting money on machines that are a repeat of what they already have I won't change my VLF, because if I want to find tiny nuggets I use the 5.3 coil and if I want to go deep I use the 14x10 or the 15" Concentric which works like a VLF version of a Mono, A GPX 4500/5K would be next on my list and another GMT because both of these two are bench marks and if a person has no success with these two then it's down to their skill level, Makes and models can only help do so much. the rest is down to doing the hard yards. We can only blame the machine for so long and chopping and changing is not the answer.

    I sure agree with you on the GB system on the MXT auminesweeper! I've got the GMT, same system. The ability to run in autotrack, yet lock it at any time, manually GB if you choose, or do an auto Ground Grab at the press of a button is an incredible system! That system on the MXT/GMT has been around for going on two decades, but, it's timeless, and the best of all worlds ground balance wise!

    Happa -- I agree with Chase on the buried coins -- which will also help to see if you might have a faulty machine. I doubt you do, though; but, some testing might be in order. MEANWHILE, I would DEFINITELY make it a priority for a little while to go back to what you used to do, and "compare signals." YES, your Safari vs. their E-Tracs and Explorers would have given similar tones on a buried target, when comparing signals in the past -- but, that's why I think comparing signals now, with their FBS compared to your Equinox, would be so immensely helpful. YES, the sounds are different on FBS vs. Multi-IQ, but you would be comparing a "known" (FBS sounds on a deep coin) with an "unknown" (Equinox sounds on a deep coin), which should really, really help you to learn the "unknown." In other words, if they locate a deep, likely-to-be-wheatie target, and call you over to listen, you can listen with THEIR machine, first (and you'll of course recognize the target's sounds given your prior experience with FBS), and then, work the target with your Equinox, and listen closely to how the machine behaves. This will help you to figure out in your mind "what sounds like THIS on an FBS machine sounds like THIS on the Equinox." Yes, I have dug deep wheats that are down into the zinc range, and the same with deep Indians. So, you could be passing over some. They also sound much more subtle, at depth, than a shallow penny sounds. I at times will even get some occasional high-tone chirps mixed in, from certain angles, on a deep wheatie or deep Indian -- i.e. much higher than what you'd expect for a penny. Bottom line, burying targets at different depths and working them with your Equinox, and ESPECIALLY "comparing targets" with your FBS hunting partners, should move you quite a bit closer to having success with your Equinox. Don't lose confidence; I promise you that the Equinox (at least, one set up properly and working properly) will find coins every bit as deep as your buddies' FBS units, in most types of ground (including everywhere I've hunted). And for what it's worth, my machine of choice for many years was an Explorer, and I run a CTX now alongside my Equinox...and so when I say the Equinox is every bit as deep as FBS, it's a statement I feel confident in stating after through testing and experience with both Multi-IQ AND FBS.

    Overall Rating: 4.5 out of 5 Big Upgrade vs. AT Pro: Short Answer - YES!. The Garrett AT series is a solid detector series. The AT pro brought pro features, including a completely waterproof detector, high reliability and stable operation to the mid price range and it is no wonder it became so popular but it is getting a little long in the tooth, never had stellar ergonomics, and is now falling behind feature wise with its competition and with the release of the value priced Equinox and Kruzer series detectors, can no longer claim the high feature to price ratio crown that kept it a best seller for years. The AT Max added some bells and whistles (built in wireless, slightly improved ergonomics) and upped detector gain to placate the "depth is everything" crowd to its detriment (it appears to now be a mixed bag from a stability standpoint - be careful what you wish for, folks). The Equinox vs. AT Pro: Waterproof: Both are fully submersible up to 3M. Tie. Ergonomics - Equinox is not the best machine ergonomically speaking (the First Texas F75/T2 machines retain that crown IMHO), but it is definitely better than the AT Pro. Lighter, better balanced (though still nose heavy), much easier display to read, and intuitive menu navigation vs. AT Pro. Backlit display a plus on Equinox. Prize goes to Equinox. Wet Salt Beach Performance: Multi IQ multifrequency operation enables superior stability even at high gain settings vs. AT Pro on wet sand. Depth: Deep as any machine I have used. I have not been limited by its detection depth so far in any situation, except unusually highly mineralized soil conditions where no VLF machine performs well (most people use Pulse Induction machines in this particular relic hunting situation). Recovery Speed: Variable recovery speed settings enable the Equinox to be used in a variety of site conditions from a very trashy home site, where you can separate the keepers from the junk to deep silver seeking in a relatively pristine park. AT Pro recovery speed is decent but fixed so separation in high trash environments suffers even with the smaller "sniper" third party coils. Multi IQ vs. Single Frequency - Multiple Multi IQ profiles enable the Equinox to be optimized for specific targets such as high conductive silver, small jewelry, gold nuggets, mid-conductive relic buttons, deep nickels. It is like having a multiple machines in one package that enables you to tackle a variety of detecting situations. The AT series has even fallen behind discrete "single frequency" machines at similar price points like the Nokta Impact and Makro Kruzer that enable multiple different individual frequencies to be selected one at a time depending on the targets of interest (low frequencies for high conductors like silver or mid frequencies for all around detecting and high frequencies for mid-conductive targets like gold jewelry and relics). Equinox takes that to the next level by enabling the multiple frequencies to be transmitted SIMULTANEIOUSLY which enables stable target ID acquisition, precise, yet forgiving ground balancing, enables signal processing filters mitigate iron falsing, and gives the stable salt beach operation I described previously. It is like having the AT Pro and AT Gold plus a higher frequency gold machine all wrapped up in one machine. Equinox wins this one. Third Party Coil Support: Right now, ML has only announced three coils for the Equinox, two are now available (the stock 11" DD and a 6" round DD), with a larger 15 x13" elliptical open coil being available soon. AT Pro has been around long enough to have a number of third party coil manufacturers make a variety of coils beyond the Garrett OEM coil lineup. So at this time the edge goes to AT Pro, but this will not last long. High praise so far for the stock Equinox coil and 6" coil, and the third large coil should have 90% of the bases covered. User Settings and Future Upgradeability: First of all the default user settings work great out of the box. So, it is a great turn on and go detector. You simply, choose the search profile desired, let the Auto EMI noise cancel choose the quietest detecting channel, ground balance as necessary, and start swinging. With all the built in search profiles you can explore different areas of detecting you might not have thought about because of the limitations of your current machine (like gold prospecting, or relic hunting in highly mineralized soil). But you have the flexibility of exploring and adjusting advanced settings and customizing the tone settings to your liking. Finally, the Equinox has a connection that enables you to upload future firmware updates that either fix bugs or that may allow future performance enhancements. Other than adding accessory coils, you will not squeeze much more out of the AT pro as it ages in your detecting arsenal. Rechargeable Battery: The battery lasts a long time (at least 12 hours continuous detecting), is user replaceable, (should last 3 to 5 years or more under normal usage), and charges quickly (fully charges within a couple of hours from "empty". You can even charge the battery on the go (i.e., while detecting) from a portable battery USB power source affixed to your detector shaft if you are so inclined. I know that there is something about the ability to pop in some AA batteries in a pinch, but I have never had this detector let me down because of a rechargeable battery problem. On an all day detecting run I have not gone below 2 bars. So if you forget to recharge your battery from the last detecting session, you likely will have more than enough juice for a couple 3 to 4 hour back-to-back hunts on separate days. Neutral on this as this is more of a personal preference thing because you can go back and forth for hours debating the merits of "built-in" rechargeable batteries that cannot be substituted with conventional batteries "if something goes wrong with the rechargeable". I prefer the Equinox rechargeable even though a few folks have reported battery or charging circuit failures. Built-In wireless audio using both readily available Bluetooth accessories you can buy from Amazon (800 includes a wireless headset) and also proprietary wireless receivers (included with the 800, into which you can plug your favorite headset). I could go on, but we would start getting into the weeds. What Do I Like Most: It's versatility. I have been able to get rid of a few "specialized" machines as a result of its ability to be a jack of all trades, and a near master of some (shallow water salt beach hunting, relic hunting in trashy plowed fields). What Do I like Least: The shaft design seems like an afterthought and seems to be a weak link although ML is honoring their warranty, the issues are relatively minor and can be addressed in various McGyverish ways (duct tape anyone?), don't manifest on every detector, and their are some great, superior third party shaft options out there which even if you spend the extra bucks to buy one of these still enables you to spend less overall than you might have on arguably less capable machines because of the excellent value pricing. Do I recommend it as an upgrade to your AT Pro? Yes. One last recommendation: Peruse this forum especially Steve's compilation of other Equinox info in the first sticky post and determine whether the Equinox 600 or 800 is the right choice for you. HTH

    I have only detected with Steve twice at Crow Creek, but both times I made an amazing discovery. The first discovery I made was that you don't ever let Steve get in front of you, the ground will be sterilized after he passes through. The second discovery I made was that you don't ever let Steve get behind you, he's like a turkey on a June Bug. Anything you miss, which is everything for me, he will have it in an instant. In other words, you get it the first time or it is gone forever, no second chances.

    Part III Gold As it turns out there is tiny -100 mesh gold just about anywhere you stick the shovel. In any pan you're likely to see 3 or 4 tiny specs of gold and a lot of black sand. The problem is as old as time, find a concentration and figure out a way to recover it. What I discovered on the gravel bar was a thin flood layer about 4 inches thick under about 8 inches of overburden. The layer was distinct because it contained mostly sharp cornered gravel rather than typical rounded river gravel and it contained a lot of mud/silt/clay binding the layer together. Once you get a decent hole started you can chase the layer, pushing the overburden in behind you. A typical pan of this material is likely to contain 30 to 50 colors, mostly -100 all the way down to -400. I had a pocket magnifier and looked at this stuff under 100x magnification. It's incredible, but you really have to get a lot of it to have any real weight. It really looks impressive when you have to black sand to highlight it, but when you pan off the black sand this stuff will float right out of the pan. I had reconfigured my Gold Cube to be more of stacked sluice, capable of handling 1/4 inch material. I added Deep V black matting to the top tray, one of the new esoteric "catch it all miracle" mats to the second tray and Deep V in the 3rd tray. The top tray was catching 90 percent of the gold, so I only cleaned the bottom trays at the end of the day. I would dig 2 buckets (4 half buckets for carrying ease) classified down to 1/4 inch then run it through the Cube. Photo 1 is what typically I would get out of 2 buckets. I would pan it down to the black sand and if there were any pickers I take them out and dump the concentrates into another bucket for later processing. After a couple days it was clear that this type of gold production wasn't going to change my lifestyle much. The most I ever ran was 10 buckets. After a few days I panned off the +50 mesh gold for 2.87 grams. Clearly I wasn't going to get rich on this project. But, it was better than being home in Yuma at 118 degrees. My girlfriend would occasionally get energetic and help shake the bucket classifier, but she was satisfied sitting in the shade reading. I figure I was getting about 1 gram of gold per day, working a couple hrs, then swimming, fishing etc. A more dedicated person with a sluice tuned for beach type gold could obviously do much better. After she left, I started exploring and sampling in more remote areas. A lot of hiking and the best I found was an area with all this riverside sedge grass growing right on the bedrock. It involved a rigorous hike on a very narrow trail overgrown with poison oak. I stuck to panning because I didn't want to haul much equipment in there. An unbalanced pack on that steep trail might have been disastrous. The roots of this sedge were like natural miner's moss. They were so tough I chopped them with a hatchet them shredded them up in a bucket of water. It might take an hr to get 1/4 bucket of this material, but it was so rich in fine gold. In photo #2 is the gold I took out of one pan from a crack under the sedge roots. Unfortunately, there just weren't many of those. The weather had turned really hot, so I would sit on a ledge waist deep in the water and pan out my 1/4 bucket. Again, I would pan down to the black sands then save it in a concentrate bucket. After I got tired of panning I would have to waste time until the sun set enough for the long hike back to my Rokon. Again, if I had been serious with the right equipment, I could probably get 3 or 4 grams a day until I ran out of sedge grass. So, after 3 weeks I decided to go get some big gold at Rye Patch, and we know how that turned out.

    Part II Every year I devise some new scheme to get the gold out of that river. One year I even set up a gravity dredge with 60' of 4'' hose. It worked fine, but it really takes 2 people to manage it. If you get a blockage it's an absolute bear to drag that hose out, shake out the blockage, then get it all back in the water and re-charge the suction. This year I decided to just concentrate on the flood gold and work less hard. During the past winter I watched various You-Tube videos of the guys on the beaches trying to capture fly speck gold. I figured I could find a decent inside bend of the river and dig the easy stuff off the banks. My plan got a little further complicated when my girlfriend decided she would like to join me for 10 days on the river. Mind you, this is rough, dry camping. Since the BLM roadblock, the only camping space is an old helicopter landing area, over a mile from the river with no local water source, and certainly no toilet facilities. I traveled ahead by 4 days to set things up and she would fly into Sacramento. I set up a decent camp, stand up room tent with an inflatable queen bed. I had pre-positioned bear spray easily accessible under the awning and in the tent, just in case. I set up a potty area with one of those toilet seats you put on a 5 gallon bucket. I bought the potty bags that help keep the mess in order for later disposal. I found a decent gravel bar with about a half mile walk from where I could park the Rokon, cleared the trail of poison oak and set up a portable shade and a chair on the gravel bar. The only real hazard was a steep section of trail with about a 50' drop, with the trail littered with dry oak leaves. They can be like stepping on roller skates in that kind of terrain, but I did the best I could. She arrived and on the drive down the nasty washed out road she started to wonder what she had gotten herself into, but she was game and soldiered on. I pointed out the poison oak all around the camp and cautioned repeatedly, "don't leave the trail". So it was for the next 10 days. We rode double on the Rokon and only crashed 4 times, all at low speed and generally into the blackberry bushes. No major injuries, minor scrapes, bruises and stickers. The hike proved to be a challenge, particularly the nasty 50' steep section. She developed a pattern of places to stop and catch her breath and take a drink of water. She likes to think she works out at the gym, but this was a bit different. I kept telling her, "it's the cardio", you'll get used to it. She didn't weigh 130 lbs soaking wet when we started, but managed to lose 7 lbs in the 10 days on the river. In the river I had a net bag of beer, soda and water. I carried fresh snacks down everyday so it really was paradise, kind of. I would drive the Rokon down to the spring every evening and fill up a 5 gallon tote bag of water for bathing. I'd heat up enough and fill a bucket with warm water. We used a gatorade bottle with the top cut off as a scoop to pour water for our shower. The bear only visited once. I carelessly left the trash out and there he was. I scared him off and didn't have to use the bear spray. At the end of 10 days, my girlfriend had to fly home reluctantly. In Part III, I'll talk about the gold....

    The secret to the Minelab GPX series is thoroughly understanding the timings and when to use each one. Timings are variations of the basic pulse induction technology at work in the GPX series that gives you far more flexibility than exists in other pulse induction detectors. Unfortunately this extra flexibility also adds complexity, and so it is not unusual that some people may not be using the optimum settings in many cases. It is very important when investing in a Minelab GPX detector to take the time to read the manuals and study until you fully understand what the settings do and how to adjust the detector for the best performance. Otherwise you will not be getting all the potential out of your investment. The chart below shows the timings and what GPX models they are available on along with a general description. The descriptions are from the owners manuals that are available by download at the bottom of the page. In general you should always use timings as near the top of the chart as possible, with the exception of the Salt settings. Those are for alkali flat and salt water beach areas only. Using timings designed for more mineralization than is actually required may result in less depth on desired targets. Imagine the timings as another sort of ground balance setting. Low mineral settings are more powerful than high mineral settings and should be used whenever possible. Some confusion is the result of the timing names. Some people assume the Fine Gold timing is best for fine gold. This does make a sort of sense, but the fact is Fine Gold is just better than other high mineralization timings on smaller gold. In milder ground Sensitive Extra will obtain better results on small shallow gold. It is also very important to know that some timings work better with one coil type or the other. Minelab GPX Timings Chart Little or No Mineralization Coin/Relic (GPX 5000 ONLY) Coin/Relic is for use in lightly mineralized soils including many beaches and loamy soils. It offers maximum detection depth on a range of target sizes, significantly greater than any other timings. However, if the ground is any more than lightly mineralized, the detector may not ground balance properly. On ocean beaches containing significant quantities of black sand, better results may be had by using Normal or Salt settings. Mild Mineralization Sharp (GPX 4500, 4800, 5000) Sharp is similar to Normal but creates a more powerful detection field. It is capable of an improvement in depth, but is more susceptible to interference and will increase the severity of false signals in difficult grounds. This timing is best used in quiet conditions and can work well in combination with Deep Search Mode with a reduced Rx Gain setting. Sharp is an excellent tool for pinpointing faint signals due to the very "sharp" signal response. Sharp will work best with DD coils in most gold field locations. Medium Low Mineralization Sensitive Extra (GPX 4000, 4500, 4800, 5000) This timing may increase the signal from certain hot rocks near the surface, but can actually help smooth out the Threshold in certain ground types, particularly with Double-D coils. In mild ground conditions Sensitive Extra will provide the best signal response on a small, deep target. Medium Mineralization Normal (GPX 4000, 4500, 4800, 5000) Normal gives you the best performance on a wide range of soil conditions, and it will provide the best depth on a wide variety of target sizes. It works particularly well with the supplied 11" DD search coil for general detecting. You should always use Normal in new areas where you are unsure of the soil mineralization and the depth of targets. Medium High Mineralization Salt Coarse (GPX 4000, 4500, 4800) The effect of alkaline salt mineralization is vastly different to the effect of ironstone and mineralized clays. Normal should be tried first in these areas, but if the Threshold is too unstable then better performance will be obtained in Salt-Coarse. Using the Salt-Coarse timing may result in a loss in signal response to smaller targets. However, the response on larger items remains relatively unaffected and ground noise is usually minimized. Medium High Mineralization Salt/Gold (GPX 5000 ONLY) Provides the best signal response on small to large gold in salt saturated and mineralized ground conditions. It should work well on dry inland salt lakes, high salt concentrated goldfields, and mineralized saltwater beaches. Extremely salt saturated soils may still need to be searched with the coil switch in Cancel (using a Double D coil). High Mineralization Fine Gold (GPX 5000 ONLY) Fine Gold is sensitive to smaller targets in highly mineralized ground. It provides a sharper signal on small gold compared to Enhance, and improves the detectability of rough/flaky gold and specimens, while ignoring most hot rock signals and false ground noises. Shallow, highly mineralized ground where gold has been found previously should be re-examined with Fine Gold, and best results will be had by using the optional 8” and 11” Commander Monoloop coils. Note: Sensitive Extra will provide superior results on small gold in milder ground. Very High Mineralization Enhance (GPX 4500, 4800, Improved in GPX 5000) Runs quietly in most heavily mineralized, variable and "hot rock" infested grounds using a monoloop coil. It is more sensitive and detects deeper than Sensitive Smooth but can be slightly more affected by severe ground mineralization. Severe Mineralization Sensitive Smooth (GPX 4000, 4500, 5000) Sensitive Smooth is optimized for an improved response on smaller, shallow nuggets in severe soils. There is a loss of depth on bigger targets; so you should not use this setting when seeking out large, deep nuggets. Sensitive Smooth is best suited for use with monoloop coils in difficult soils. It eliminates most false signals from hot rocks, and ground mineralization, whilst retaining excellent sensitivity to small targets. The example below shows three common timings and where they should be used. It also highlights why using the wrong timing for the conditions can result in missed targets. Minelab Mineralization and Timing Example The following chart illustrates the procedure for finding the correct timing for each situation. In general, always start with the Normal timing. If the detector is stable and quiet, try timings on the left - Sensitive Extra, Sharp, or in rare cases, Coin/Relic. If ground noise or hot rocks present problems in Normal, then try timings on the right - Fine Gold, Enhance, or Sensitive Smooth. Salt settings should generally only be used on alkali ground (salt flats) or salt water beaches, but may have applications in other ground. The goal is always to find the most powerful setting that allows for stable operation. Each timing can be adjusted within certain parameters, primarily through the use of the Gain and Stabilizer settings. Adjusting for a lower Gain, for example, may be preferable to going to a less powerful timing.

    The River I spent several weeks in early July, panning and sluicing on the N. Fork of the American River. I've been going to the same 10 mile section of the river for over 20 yrs. That part of the river is designated Wild & Scenic, so no motorized equipment and no claims. It's one of the few places in CA gold country you can access a free flowing river without stepping on someone's gold claim. Access is not easy, although there a a number of trails up and down the river. They're all rugged, often steep and always overgrown with poison oak. I have often encountered "locals" who at various times attempt to eke out an existence by panning and sluicing the river. Generally friendly and sometimes willing to share local knowledge of the gold. When I meet them I make a point to brew up a big pot of spaghetti and feed all comers. Many years ago, I met a guy my age driving a new Jeep Cherokee. He was socially awkward, but I learned he was a software engineer from the Silicon Valley and had taken up gold prospecting on weekends. He was not very successful, so my 6 yr old son and I invited him to come dig in a hole we had started. He sluiced a few buckets and declared that was more gold than he had ever found. Skip ahead 10 years, I found him living in a tent on the banks of the river having spent 2 years pursuing the golden dream. He was eking out an existence and seemed to be perfectly happy. Imagine a 6 mile hike uphill, just to reach a paved road, hope for a ride to town to get supplies then repeat the process back down. Supplies are limited to what you can afford and carry on your back. The local mining supply store pays 80 percent of spot, for good clean gold. This guy still had the math and engineering brain so he could tell me exactly how much he was earning per hr, although he did not factor that it was in fact a 24 hr a day job, living on the river. Every now and then "flatlanders" discover the place and bring down a bunch of gear intending to strike it rich. They are soon disillusioned and I find their gear stashed in the woods. I've seen one sleeping bag stashed in the same spot for over 4 years, untouched. Buckets and digging tools get carried away by spring floods and I find them littered on gravel bars. Access There is an old mining road ,overgrown, heavily rutted, washed out and frequently blocked by blown down timber. It currently takes me about an hr to travel just over 3 miles down that road crawling in 4 wheel drive low locked in 1st gear. At one time you could drive to within 100 yds of the river. There was a fabulous camping spot under a massive oak, with a spring nearby. In their infinite wisdom, the BLM blocked the road about 1.5 miles from the old camping spot. They brought in some heavy equipment and dug tank traps to block all future traffic down the road. For many seasons I hiked the rest of the way down on a variety of trails. A few yrs ago, my son, then strapping teenager and I started hacking an ATV trail around the tank traps. We spent a few hrs a day for over a week cutting a new trail. It's passable by ATV to this day, but you really have to know the danger spots or slide right down the hill. I've winched my own ATV up that zone many times. More to come in Part II.....

    Thanks, there is a lot to learn but I'll get there. My job now is to not worry about looking at what other detector "maybe" better but to learn what I've got and learn them so I know them inside out. JW found 14 nuggets that in total weighed .23 of a gram with his Nox + 6" on it's first day out ?

    I hope Whites always keeps that GB system because it is so good and fast, I would like to see them add a see through mineralization feature to that GB and then depth would be improved along with target ID, But I would like to see Whites add 2 extra push pads to the MXT for manual GB.

    All the charge tiems I have reviewed posted by folks, yours is way outside the norm. Most charge less than 4 hours. Mine does too, like 3 hours 15 minutes. Make sure your charger doens’t have 2 rated charging jacks for current. Some have both a 2.1a and a 1amp port (s).

    I have a 14x10 on my VLF and next to the 5.3/6" coil it is my favourite and it is the same weight as the standard 10" DD but it adds a few inches depth on coins and on larger items it goes really deep.

    Hi Simon, On re reading my post I thought that I may have come on a bit hot & ruthless on you. Sorry. Wasn't meant to come across that way & glad you didn't take it that way. Whew... Auto ground balance may not be the absolute best ground balance. By being able to fine tune it by manual means can improve it even better or get your detector to run hotter. Bit like when you auto tune your 4500. As you found out that by doing an auto tune, you can actually improve it more by manually manipulating either up or down. There are many little techniques that come into detecting & by learning a single detector & getting to know its quirks inside out, the better off you will be. Although detectors have many similarities each individual one has its own little traits & personalities, both good & bad. By chopping & changing detectors regularly you are not going to learn any of them well. You are best to focus on one. Which one of your high frequency VLF's will that ONE be? If I were you I would be focusing on your 4500 & Evo coil, but take the little coiltek joey mono with you as well...always. The VLF's are for fly poop gold. The 4500 will get you slightly bigger gold deeper & bigger bigger gold even deeper.? Good luck out there if you head to that gully. JW

    Those are really good settings for deep silver and copper. I don't know what to tell you but try putting some into the ground at depth in a test garden and see what they sound like shallow vs. deep and in various modes including single frequency. Also, check out Calabash Digger's discussion about how even pure non-ferrous targets can give a ferrous grunt (when in AM) off the edge. Give AM a try if you are not already doing so (you can turn down the ferrous volume) to see if that enables the high conductors to stand out.

    This is where my detected goodies go, not that I have enough to bother stealing but If I ever do it will be safe, it's bolted down internally and weighs so much three people are required to lift it and even then they won't get far as it's just so stupidly heavy. You just drop anything in the top, spin the handle and its safe ?

    I have had many detectors that could coin, relic, jewelry, and nugget hunt well, but then had to have another detector for saltwater detecting. Now I can nugget detect one day and hunt in saltwater the next. There is no other detector I am aware of that can do so many different metal detecting tasks and do them all not just well, but in many cases better than machines dedicated to those tasks. Multi-IQ is very powerful. Main dislikes? Handle grip is a little large for my hands, wish it had a 6" x 10" fully enclosed coil, expanded target id spread would be nice.

    It's not just you, that is the world we live in now, $1000 for an Iphone and they bring out a new one 6 months later, and the new comers to the hobby who work for these companies are trying to do the same to detecting and we have had quite a few machines put on the market that are less than Inspiring even on a good day, I would much rather they spent a couple of years getting it right than blow my hard earned cash and regret it a week later as we have seen in the past,

    Well the guy that made the first video I was watching has made a second one. It started off with him doing a comparison of a At Pro and the Makro Multi Kruzer on different targets at depth. He said he was running the MMK in three tones doing the test this time. He went from one two the other as his testing went with the MMK hitting the target and not always with the AT Pro. As time went by he didn’t pickup the Pro anymore and didn’t put the MMK down anymore. He was the same one in his other video that was saying how much it chatter in 4 tones plus loss depth in 3 tones. Here he was making finds that he never could before with other Detectors. Maybe next time he’ll put brain in gear before putting mouth in motion. Chuck

    Welcome to the forum EMField, thanks for your post, I found this little tacker with my Gold Bug Pro (G2) 0.021 grams. It's tiny. it was only about an inch down in a crack in some bedrock, I hadn't used this coil before that day (Nel Snake) other than playing around in my yard testing it and a run in a creek to try it out, I didn't even get my coil dirty as I was just searching bedrock as there was no junk targets in the area, the first signal I got after about 15 minutes of detecting was gold ? There is no doubt the G2 is capable of finding gold, it's actually very good at it but there are more sensitive detectors to small gold out there that go deeper on it but then I guess comes the question, just how small do you want to find before it becomes not worth it ?

    Hi all, had a half day to go detecting today, so I went back to that new patch and was able to find one more small rough nugget. Searched a lot tried to expand the area or find source but no luck. So I want of searching for a new area, looking on a hillside next to a wash where I found a few nuggets. No luck, but I did notice a steep wash up ahead that I couldn't remember detecting. Found some nuggets nearby so I figured it was worth it. Ended up finding 4 more nuggets in a new patch. All small, but way better than a skunk. The darker nugget was from last weeks patch. Chris

    Thanks a bunch GB! I know you weren't looking for the exact spot and I don't share it anyways so no worries but I have no problem giving some tips because people have helped me along the way and if it helps speed up the learning curve and find you some silver I'm happy. I was at a public park and hit the sledding hill on the inclined part not at the top and was using low disc. Field 2 on the Equinox 600. I was actually trying to find nickles which read 12-13, and dug several pull tabs and also botyle caps trying to find gold, and buttons.

    White's 24K is starting to get a little depth now. I just pulled this one at 8" while using the 6" round concentric coil. It is just bigger than my thumb nail and weighs in at 2 grams (30 grains) and was found with the 24K. I still have a few of my initial order not spoken for (at this time).

    Jim, Those are very strong and kind words...I'll accept them lightly as I know others on here have put more effort and time sharing their experiences. Yes I have been fortunate with many detectors, but at the same time, I try to put myself in the best situations when trying to make a machine perform. Then there is the skill of the operator behind the detector and I feel years in the field have earned some tidbits of knowledge. Hats off to you for doing something fun that I wish I understood...but in reality it is lack of time. I too am amazed at what a person can do with a rod/probe. I have a good friend in NV who an tell the difference from rusty cans, glass, and hard metal...from rock. He put himself through college digging privies. Last time I witnessed him in action, he pulled about $3K in rare bottles 4 to 6' down. He walks around a site sticking the rod in the ground feeling for the right ting and listen for the right ping. He found this Seven Troughs NEV bottle on that day and had it sold for $900 before he got back home that night.

    Low resolution raw LIDAR data is publicly available for free for about 1/3 of the United States, mostly the east coast and developed areas. High resolution LIDAR (1-3 cm) is available in a few areas. Mostly for environmental studies or only available privately. Without LIDAR we have to rely on DEMs (Digital Elevation Models) for elevation data. These are mostly just a rehash of the old paper topo maps with hand drawn elevation lines converted into even lower resolution digital point shapes represented by light and dark shades on an artificial black and white image. The shades of gray of each pixel represent different elevation values. These DEMs have a high factor of human input error. Mountains and valleys sometimes appear wher there is nothing but a road or a visually confusing feature on the original topo map. If I were to describe the conversion method for these topo's derived DEMs I'm sure you would be in awe of the influence of primitive technology in our "modern" lives. LIDAR is really just a (sometimes) higher resolution version of this system with the difference being the LIDAR points are defined by direct reflection of a laser light rather than ground observations with optical equipment, geometry and trigonometry - traditional survey equipment and methods. The final result in either case is still a grid of values most usually visualized and stored as a photo image in shades of gray. Although just about any data storage format will work humans still naturally understand complex data with their eyes better than any other sense. The features you see on your link were buried in the original LIDAR data. A lot of post processing (number crunching) is necessary to turn the raw data into detail like you see on the website linked. In other words the LIDAR system itself is not discriminating out the trees and ground cover. That is done by applying some pretty complex algorithms to the data after the fact. All of that processing actually lowers resolution and accuracy. To be truly effective for any particular purpose those algorithms are usually customized to the project requirements. We use LIDAR on some of our private mapping projects along with matching high resolution georectified aerial imagery. This can reveal several features you could never see from the ground or the air. We can build 3D models that very closely conform to reality and move through those models in three dimensions. This is a very realistic process and allows us to include measured, extrapolated or even sensed data for underground features. Mining companies love this stuff, not so much for project management but for making presentations for investors. The size of the data involved is a very real problem. Terabytes of data are needed for even a small area and processes take a very long time to run on data that size. Just obtaining the data can be a very long process. We can order a LIDAR scan of just about anywhere in the world but the logistics of producing that scan can be overwhelming. A good high quality scan requires several manned precisely located ground stations as well as some very expensive aerial equipment. Just getting the time booked can be a long wait and getting the skilled ground and air crews working together under ideal conditions can be a virtual impossibility. Add in the difficulty and expense of placing those ground crews on landlocked parcels, hostile territory, difficult terrain or legally challenged access can make the entire process prohibitively expensive and slow. Like much of what is possible in theory the theoretical 1 cm accuracy of a LIDAR scan is rarely if ever achieved in real life. This is not a new technology, it's been around since the 1960's, but until now the technology to push it into the realm of useful and affordable has been lacking. That is changing and I look forward to a time when high resolution ground scans can be considered an accessible tool for many professions. Until then it is a gas to work with small areas in high definition, I only wish more clients could afford the time and money involved in high resolution LIDAR.
