Great work Fred! I would be plenty happy with that pile of silver myself and a little gold sweetener is nice.

Some rings can be returned - did you read my note at the end of the Garrett in Hawaii article referenced above? Pretty cool when it can be done and it can't happen if you do not find the ring first. Also http://www.detectorprospector.com/forum/topic/54-lost-ring-returns-to-alaska/ The CTX 3030 is a great beach hunting detector. I am a little less confident in it as a true in the surf type detector. I was planning on taking the Garrett ATX to Hawaii with me and the Minelab CTX 3030 as backup. The plan was use the ATX most of the time, and possibly use CTX on the beach or wading but keep it out of heavy surf. Frankly, the machine is just a little too nice for the real rough and tumble treatment. The ATX and CTX are both warranted waterproof to ten feet. Most real surf detectors are 100 feet or more. I have had two underwater detectors leak on me before, both brand new out of the box. The old White's Surf PI, two models back, prior to Surf PI Pro and newest Surf DF. My first water hunt to Hawaii died on arrival when that detector leaked. The box design was redesigned later and I have had several Surfs subsequently with no issues. The other was the old Tesoro Stingray II, model prior to current Tiger Shark. Both were replaced by their respective manufacturers. After that first failure in Hawaii I have never gone with less than two waterproof detectors on an important trip. It has also made me cautious about waterproof detectors in general. The CTX has had issues with the battery seal and to a lesser extent the USB port seal. Mine has been in the water a couple times with no problem but I still was not wanting to put it to the ultimate test in rough surf. The more I thought about it, the more I realized I was also placing a pretty big bet on the ATX, a detector so new it has no track record. I always wanted a new Surf PI Dual Field and so when by chance an opportunity arose to get one I jumped on it. I believe in serendipity and so decided at last second to take the Surf to Hawaii in place of the CTX. It seemed like better insurance as it is one of the waterproof to 100 feet models and I have done well with prior Surf models in Hawaii. Not to belittle the CTX however. Mine will still get plenty of beach use in the future. The first time in the water it scored me a nice gold ring, and on second outing also. One of the more successful beach hunters, Gary Drayton, has used the CTX extensively and has even written a book about using it available here. I have it and his book on reading the beach and hardcore beach hunting, all very good books. I would recommend any of his books based on what I have read so far. He also has a great blog at http://hardcoretreasurehunting.blogspot.com with tons of great tips and excellent photos of eye-popping finds. If it can't inspire somebody nothing can! The attached photo shows my finds from my first few outings with the CTX 3030. I took an immediate liking to it for obvious reasons.

SINGAPORE (Reuters) - Gold climbed to its highest in nearly six weeks on Monday as a dip in equities lifted bullion's safe-haven appeal and improved investor confidence in the metal. http://economictimes.indiatimes.com/markets/commodities/gold-hits-six-week-high-platinum-up-on-south-africa-strikes/articleshow/29104631.cms

I am an avid metal detector user and I like always being at it. Just because there is no gold prospecting for me in a given time frame is no reason to not go metal detecting for gold. There are a lot more ways to find gold than prospecting, and so jewelry detecting is very high on my list. If you like finding a gold nugget, I do not see how you could not also be excited about digging up a gold ring. Jewelry detecting and nugget detecting share many common traits, not least being the hunt for gold. Both also require a high tolerance for digging trash items, and both are best done with detectors made for the purpose. It just so happens that the detectors best used for nugget detecting are often the best to use for jewelry detecting. In other words, a lot of you guys are already outfitted for this! There are two general ways to hunt for jewelry - on dry land, or in and around water. Let's leave the dry land for another article and focus on the water detecting for now, since I am gearing up for a water hunt myself right now. Almost any detector, with the remarkable exception of the most expensive one you can buy, comes with waterproof coils and can be submerged to the control box. Minelab PI stock coils are not warranted waterproof but only water resistant so it takes aftermarket coils to get them up to speed. But they are a poor choice for wading as there is probably no machine I would like dropping in the water less than a Minelab GPX 5000 with high amp battery attached. Detectors that can be hip or chest mounted offer even more flexibility for wading applications. Few nugget detectors are fully submersible, but there are some, most notably the Garrett AT Gold, Infinium and ATX, all waterproof models. Jan 2019 note: see also Makro Gold Kruzer and Equinox 800. Water detecting can be broken down into fresh water and salt water detecting. Fresh water detecting is pretty straight forward since fresh water is invisible to your detector. The tuning and operation of the detector is similar to what you do on dry land. All you have to worry about is keeping the electronics dry, and recovering targets underwater. Fresh water swimming holes are great for jewelry detecting, and there are many fresh water stream and river opportunities for gold prospectors. Any good gold prospecting detector also works well for freshwater beach hunting. The Garrett AT Gold has an obvious edge for being waterproof. The Tesoro Lobo gets special mention for being convertible to hip or chest mount. In fresh water VLF detectors usually have an edge due to large amounts of trash often being present but PI detectors do have their place in fresh water detecting. The only way to know is to just give it a go and see how much trash there is. The nice thing about beaches though is the digging is easy compared to what nugget hunters often face. Salt water adds a whole new dimension. Salt water is conductive, and therefore a hot metal detector can actually get a signal from salt water or wet salt sand. Many prospectors already know the issues surrounding salt and alkali flats. Detectors that are used in salt water need some way to tune out the salt signal. The problem is even worse on beaches that have mineral content, classic black sand beaches. A white beach composed of broken down coral and shells is no problem at all, but add volcanic material and the issues compound. Most prospectors would not be surprised to hear that pulse induction (PI) detectors have an edge in dealing with salt water scenarios. There is an unsolvable conundrum however. The signal for salt water and small gold items, like post earrings or thin gold chains, actually overlaps. When you tune out the salt water, you tune out these items also. There is no solution to this problem with existing metal detectors because of the way they work. It is possible to find these items at the beach using a hot detector, like a White’s Goldmaster or Fisher Gold Bug 2, but you must be on bone dry sand. Any attempt to get near wet salt sand with these units will result in the sand acting like one giant target. Most mid-frequency gold machines handle salt water beaches to varying degrees. They will generally have no problem until you get on sand currently seeing wave action or actually in the water. The higher the frequency, the less able to handle wet salt sand. The Fisher Gold Bug Pro at 19 kHz and Garrett AT Gold at 18 kHz are not happy on wet salt sand. They can be made to function but only by losing a lot of depth. The Tesoro Lobo has an alkali setting and White’s MX Sport a salt setting specifically designed to handle wet salt sand. In general though these detectors will all work better higher on the beach and have an edge on small rings, earrings, and chains that other beach hunting machines tend to miss. The Minelab Eureka Gold and X-Terra 705 have low frequency options that make them well suited for beach hunting. The Eureka can be hip or chest mounted, but be aware the stock coil is another that Minelab does not warranty as waterproof. The PI detectors fare better, the Garrett Infinium and new ATX having an edge again for being waterproof designs. The White’s TDI and Minelab series do well but must be kept dry. The TDI models except the TDI SL have an advantage in being convertible to hip or chest mount. Be aware that turning off or not using a ground balance system can often add extra depth with a PI on white sand beaches. The TDI and GPX 5000 can turn off the ground balance setting, and the factory default on the ATX before ground balancing offer possibilities on low mineral beaches. For 2019 see the new White's TDI BeachHunter. For serious salt water beach detecting hunters turn to detectors not normally used for prospecting. Ironically, this is because the general lack of sensitivity that makes prospectors eschew these models makes them ideal for salt water. Multi-frequency VLF detectors are not very good prospecting machines but they excel in salt water. Two detectors that vie neck and neck in the salt water VLF market are the Fisher CZ-21 and Minelab Excalibur. On the PI side the Garrett Sea Hunter, Tesoro Sand Shark and White’s Surf PI are the three popular models. Minelab Excalibur II waterproof metal detector There are lots of options but if you ever want a specialized waterproof detector for both fresh and salt water and want to make a safe choice, get a Minelab Excalibur. It is probably the most popular water detector made and for good reason. It gets the job done with minimum fuss and will work well anywhere. I am a PI guy myself however. I have used the Garrett Infinium extensively trying to deal with salt water and volcanic sand and hot rock conditions in Hawaii. I have had success with the model but it is difficult to deal with, suffering from an inability to ground balance into the salt range and susceptibility to EMI interference. Huge numbers of posts exist on how to try and get an Infinium to behave in salt water. The new ATX has taken steps to address these issues but the jury is out there yet. I will be giving the ATX a good go in Hawaii soon. My latest water detector is a White's Surf PI Dual Field to back up the ATX. I have had good luck in the past with the White's Surf PI models and recommend them for people interested in a waterproof beach PI. Again, a simple unit that gets the job done, and at a bargain price. Where to hunt can fill a book, but really boils down to two things. The first is that the best finds will be made where people who wear quality jewelry congregate and engage in some kind of physical activity. On fresh water beaches where items get dropped is generally where they stay. The second item comes into play more often on salt water beaches. The waves and seasons concentrate items on layers, much like placer deposits. They sometimes bury the items too deep to find, and at other times expose them for easy recovery. Beach watching can teach you a lot. There is the towel line, where people set up shop for the day. Lots of items get lost here. Then there are the places where people tend to play beach sports, like Frisbee or volleyball. Best of all, are areas in the water where people congregate, with areas where people can actually stand on the bottom being best. Items dropped in sand obviously sink over time, but hard sand will resist this longest and keep the targets close to the surface longer. Extremely soft sand swallows items quickly and is not a good place to hunt. Areas where the sand tapers into a hard rock or coral bottom can be very good when the overlying sand is shallow enough to reach that hard layer with a detector. Beach detecting is very popular, but beach hunters have on tremendous advantage over prospectors. The finds are being constantly replenished. There is no beach, no matter how heavily hunted, that does not have the potential for finds. The more activity there is the more items are lost in a given period of time. The finds made by beach hunters can rival the best made by prospectors, as not many gold nuggets come with diamonds attached. I know for many prospectors it is about getting out into the middle of nowhere and away from the crowds. Beach hunting is not for everyone. But you can hunt early in the morning or even on rainy days, when people are few and far between. As more and more areas accessible to prospectors get hunted out, it is possible other places are near to you where gold may be easier to find. If you have a detector already you certainly have nothing to lose by giving it a go. Hopefully this post has at least made you consider the possibility. As always, volumes more information can be found just by Googling “beach detecting forum”. Here is an example of a hunt at White's Surf PI Pro and Platinum Rings in Hawaii I got four platinum and three gold rings over a couple week period. One of the gold rings is white gold so it looks like only two gold. All fairly plain men's bands reflecting the rough surf area I was hunting. There is a picture of everything I dug at the link including the junk. All the platinum I have ever found was rings, and when platinum peaked at over $2000 an ounce I cashed in over two ounces of platinum. Another very successful hunt was Detecting Gold in Hawaii with the Garrett Infinium Please note that unlike my prospecting outings I do not spend every hour of every day in Hawaii detecting. These finds are being made hunting on an average of two or three hours a day. I am not one to just sit around so detecting keeps me busy. And a good vacation can be paid for in finds or at least subsidized with some hard work and a little bit of luck.

Part of research is good record keeping. I keep a diary that forms the basis for my stories at Steve's Mining Journal. Nothing as detailed as what you are doing though. I am more concerned about recording the memories than the gold statistics. One of my smarter moves as my memory for the past is not that good and the stories are fun to look back on now. But I do have a lot of notes about what was found when and where. These days I am making a serious effort to use a GPS on my outings to map nugget finds. In time this can be valuable information if a pattern develops. Not to mention being able to find an old location years from now.

The disparity between Australia and other places is so extreme it really is as if people are detecting on different planets. It is obvious to me this is where a lot of arguments about detectors arise - people forgetting what is true in one place is not true everywhere, and what works best in one place does not work best in another. I have a long story that perfectly illustrates this but will save it for a new thread.Alaska is very low mineral ground by comparison to Australia. In fact, my old stomping grounds near Anchorage are on one of the largest continuous areas of slate, shale, and graywacke on earth. Extremely low iron content sedimentary or low grade metamorphic rock. A 6" gold dredge run all day will produce about a tablespoon of magnetic black sand. The nuggets average under a gram and the big ones weigh a quarter ounce. Nuggets over an ounce exist but are almost unheard of. I only found one right at an ounce in over 30 years of dredging and metal detecting south of Anchorage. And that was with a dredge. My largest nugget ever found detecting south of Anchorage weighed about 8 pennyweight. With a VLF. I owned one of the largest detector dealerships in the country, selling over 500 metal detectors a year for decades. Over 99% of those detectors were VLFs. It is not because Alaskans lack money or are stupid. The fact is a PI not only offers no advantage it puts one at a disadvantage in many locations in Alaska. The detectors that produce are the Gold Bug 2 and White's Goldmaster series. They can be run at full gain and run well at that. Air test one of those detectors sometime, and that is the depth you generally get south of Anchorage. Time and again visitors from other places would show up with their high priced Minelabs looking to show the locals up and we just ran circles around them. In tailing piles, detectors like the White's MXT or a host of other mid-frequency detectors rule. PI detectors have had almost no impact in Alaska. Now, it is a huge state, and there are areas that warrant a PI. My own Moore Creek mine was one of those. It had a couple nasty hot rocks buried in mild soil that gave VLF detectors fits. The vast majority of the gold found at Moore Creek was found with PI detectors. There are other examples. But those locations are not the rule in Alaska, they are the exception. What I found interesting is people who have never used anything but a Minelab PI in bad ground often get almost religious about it, and refuse to believe what I have just relayed to you. I must be making it up. That said, because of my use of the Minelabs at Moore Creek I have found more gold with a Minelab than any other person in Alaska I know of. Even in low mineral ground, a Minelab with an 18" mono is going to hit a larger nugget deeper than a VLF mainly because VLFs do got get any real bonus from larger coils. These days I target areas in Alaska where large nuggets lurk and tend to rely on my Minelab PI but I honestly must say most of the gold I find I still would have found with a good VLF. In much of Alaska it still really is just a matter of being first over the nugget, not having the deepest machine. Better wrap this up, but in the western US there is a huge variation in ground from stuff to rival Australia to extreme low mineral ground. On average most is far less difficult than Australian ground and so many areas still produce well with VLF detectors but in the southwest in particular PI detectors are the real producers. Overall the western US is in between with Alaska and Australia as the extreme opposites. Jonathan Porter told me once he thought I had an anti-Minelab bias, mostly relating no doubt to my reports from Ganes Creek, Alaska and my advice to people there not to us a PI. I can see how it would appear that way, though in later years the Minelab X-Terra 705 became very popular at Ganes Creek. Not a detector that normally gets raves from nugget hunters but it performs very well at Ganes Creek. Yet when I got to Australia to hunt with JP I think he saw that I love my GPX 5000. I think it is one of the finest pieces of metal detecting technology ever produced, and I feel almost privileged to own one and use it. It was a real joy seeing what it could do in the ground it was made for. But if I was headed south of Anchorage tomorrow I would grab my Gold Bug 2 or GMT.

Something to ponder. As far as I know the largest nugget ever found with a metal detector was the Hand of Faith, at 875 ounces of relatively solid gold. With a Garrett ADS VLF in 1980. The nature of desert eluvial deposits is the gold is usually near surface and more depth does not always mean more gold. All the Minelab PI detectors made ever since have yet to find a larger nugget in Australia. And nothing in modern times has come even remotely close to masses of gold found over 100 years ago. There is the idea that another foot of depth will result in a renewed gold rush but I do believe in many places people would be surprised to find the cream of the crop gone forever. Scrapes obviously prove that is not true of all locations but in areas where bedrock is within a foot or two all the depth in the world is not going to put the gold back.

Thanks Betty and Augie for joining the forum and responding here. You may want to watch for more questions. I for one do understand the difficulties of running such an operation. I appreciate the opportunity you are offering especially for those with no experience at all of remote Alaska. I always enjoyed my Alaska visitors at Moore Creek but it was the people who had never been to Alaska before and who never found gold before who were the most fun. Anything they found and everything they saw was new and exciting, truly life changing experiences for some. There is little that can match seeing a person find their first gold ever and knowing you helped make that happen. Good luck to you and your visitors in 2014. Maybe I will see you up there someday.

Thanks for posting that JP. I was thinking it is about time for a Minelab post, what with all the Garrett ATX posting lately. I like to spread it around to keep it even so you beat me to the punch. I have one nugget hunt so far in 2014 but no gold that day. The fact I was nugget detecting in January was a first for me regardless! Anyway, great find, and wishing you a pile more in 2014.

I would say that hits the nail on the head. If you just lean one way or the other based on what the primary use of the machine will be it is hard to go wrong. I prefer my Gold Bug Pro to the AT Gold for prospecting simply because it focuses more on that task and I do not like changing coils on the AT Gold. This will tell you how highly I think of the AT Pro and AT Gold however. The only reason I sold my AT Gold is because I have a CTX 3030 and for me they served the same purpose. Waterproof coin and jewelry detector. If I had to trade the CTX for something else it would be the AT Gold. The fact is I believe the AT Gold or AT Pro compare very favorably with the CTX 3030 and that says a lot. They are a couple super bang for the buck detectors. I was using my Gold Bug Pro in wet brush the other day though and water dripping off the brush got a bit of moisture in the box and the display fogged up. The attractions of waterproof are obvious.

Garrett should hire you Paul!

OK, email sent inviting them to thread.

This one sure brings back nice memories! My old Keene 5" dredge parked on lower Stetson Creek on the Kenai Peninsula, Alaska in 1979. The first of many years dredging on this creek and on Cooper Creek, which Stetson feeds into. This was one of my more pleasant summers of dredging. The weather was nice, the water was low, the gold was good. This location was giving up about an ounce a day, better than the average on Stetson Creek. Mainly because of plentiful shallow bedrock. The gold is almost all on bedrock in Stetson Creek with little or nothing in the overburden. The more overburden you process, the less gold you get overall as a rule. This is because Stetson Creek is a classic gulch deposit, a very steep creek with waterfall after waterfall. Mother nature's giant sluice box, and the gold has been well settled and concentrated. The paystreaks were small and very well defined, move over just a foot and it was like crossing a line, you were in the gold and now you are out. There were large stretches of creek with smooth bedrock and so little gold you would think there was none in the creek if you got into one of those sections. The gold was nice - lots of jewelry gold buy nothing really big. The two pennyweight nugget in the photo was about as large as I ever found in years of mining, though the records report a three ounce nugget having been found on the creek. Must of been a fluke from what I saw, if it even happened at all.

I have no idea what the settings are on the ATX or Gold Bug 2 so not sure what you are seeing Keith. Nothing surprising though. Some detectors do better on some things and other detectors do better on other things. Meteorites grade imperceptibly from pure stone (detectors can't find them) to pure iron (detectors go crazy on them). Weaker grade meteorites would in effect be a hot rock to a PI and a good PI should tune out hot rocks by their nature. As the percentage iron content increases to where the meteorite basically becomes an iron target, the PI affinity for iron targets takes over. The ground balance setting on a GBPI would have a huge impact on weak meteorites as targets. I would expect a Gold Bug 2 to do better on the stony meteorites. As the percentage iron increases along with size the ATX will catch up and pass the Gold Bug 2. In an area with hot rocks you run into a problem with the Gold Bug 2 sounding off on hot rocks the same as the weaker meteorites. The trick as always is to find the machine that best ignores the ground while getting the desired target to stand out as well as possible. There is no right or wrong answer per se as potential target types and ground conditions grade imperceptibly from one extreme to the other. I would also expect the Gold Bug 2 to excel on small gold. No surprises there. I guess the video more or less reflected what I would expect so in that regard I do not see a problem. It is when people show things that run contrary to what I would expect that I start getting suspicious.

Hi Rick, Well, book only made it to the mail yesterday so you probably have to wait a bit more. I sent it regular mail but it is on the way. The TDI normally comes with the 12" coil. The TDI SL can come with the 7.5" coil as one of the purchasing options. You will certainly get more depth and coverage with the 12" TDI than your Gold Bug 2 but as you saw the TDI will also miss the specimen gold there. Of course there are larger nuggets lurking also but still something to consider. There are a zillion MXTs out there so easy to get one used. I am tied up until middle of February but can hook up with you after that if you wish. Do Steve and Rita have an MXT or TDI or both you could try on some of your specimens?

Dan's passing was bad news. I do not think I ever met him but emailed a few times on coils, etc. Good to hear a replacement coil is in the works. I assume it will be advertised soon?

I prefer the horizontal boxes as they are less prone to falling over. Looks great though.

Say what? That is news. I do not see it on the website now that you mention it, but I figured that was an oversight. Temporarily unavailable or no longer being made?

Hi Rick, I honestly think that in low to moderate ground you may as well just use a mid-frequency VLF in all metal mode as a TDI. An MXT would probably do as well there in Prospect mode. What is it about a TDI there that you were hoping to achieve? I did not think the ground around Winnemucca was all that hot. I was running my GMT at max gain and it ran fine, if a little noisy on the ground. An MXT should run pretty smooth there. If you want I could meet you there with my TDI sometime. Unless you have a really good deal on a TDI and are wanting to pull the trigger. If I can use a VLF instead of a TDI I will use the VLF. If the hot rocks are making the VLF go bonkers, that is reason to break out a TDI. Just my opinion on that subject.

Hi goldenoldie, welcome to the forum! I'm guessing lot of years, lot of gold. Makes sense to me about average size dropping - we are all seeing that. Gotta love that 5000. Nice thing about detecting is it is one of the few things we get better at the older we get! Well, except for the climbing around hills part maybe. Basic Guide to Differences in the Minelab SD, GP, and GPX Detectors Great to have a few Aussies here for another perspective on things. I have to caution everyone that the US and Oz are worlds apart detecting wise. Things get said here that are rubbish in the experience of the Australian prospector due to our milder hunting conditions. I think it can be said that the majority of Australian prospectors hunting in the harshest conditions over time would agree that the GPX 5000 has proven itself as compared to earlier models. Every new model that came out people doubted, but over time each new model did prove to have some advantages. But there will always be those who stick with the good old proven reliable detector they already have and there is nothing wrong with that. "Whatever works for you" that's my motto.

DetectorPro also made the Pocket Uniprobe, which was a probe on coiled cable attached to cell phone size control box. I still have one I should dig out and try compared to the other two I have. It had a very weak speaker and no vibrate function so again got put aside.

An excellent review at Link deleted since Findmall update broke all old links I have both the Garrett Pro-Pointer http://www.garrett.com/hobbysite/hbby_pro-pointer_main.aspx and Minelab Pro-Find http://www.minelab.com/products/consumer/accessories/pinpointer/pro-find-25 and from my perspective they are practically the same pinpointer. They are VLFs. The Minelab you can turn the sensitivity up or down but I would never use it on anything but max. I had the Garrett first and have worn the paint off it. I got the Minelab for backup and since my Garrett never dies (so far) it has only been used once when I loaned it to Chris Ralph. I had and really liked the DetectorPro Uniprobe http://www.detectorpro.com/uniprobe.htm which is a PI probe built into what are basically Gray Ghost headphones. You switch between headphones and detector and head both in headphones. A bit more depth than the Garrett and Minelab but another cord to deal with and no choice of headphones. Not cheap either but you are getting headphones and a pinpointer. DetectorPro also make the PistolProbe http://www.detectorpro.com/pistolprobe.htm but it is audio only so no good for me as I usually wear headphones.It is also rather bulky. The Garrett and Minelab units vibrate in addition to audio. I actually put a drop of glue in Garrett tiny speaker outlet to shut it up so I do not attract attention from it beeping. The Vibraprobe http://www.treasureproducts.com/vibraprobe.html has been around a long time, is a PI unit, waterproof to 100 feet. I have no idea why I have never owned one since it has tempted me a time or two so I can't report personally on it. White's is on the verge of introducing a new pinpointer that should be competitive with the Garrett and Minelab and may even be a PI so may want to hold off a bit unless you are in a hurry.

That is why I started this forum! Thank you very much for that honest appraisal Ray. I very much agree with you. I also think the Fine Gold timing is misunderstood and often misapplied in the United States. Sensitive Extra is better on small gold in most locations here. I am not one to belittle the older detectors, but the reverse is true also. Do not underestimate what a GPX 5000 can do in the hands of a person that understands it. That said, I sure appreciate you contributions and participation on the forum. You are a credit to the profession.

The SD2000 is the only Minelab listed as obsolete by Minelab at http://www.minelab.com/usa/customer-care-1/obsolete In Australia the SD2000 lack of sensitivity to small gold also meant it ran quieter in bad ground. So it has or had a fan club based on that and the fact old Minelab models were easy to modify. Lots of mods out there. Minelab WILL NOT work on modified units. I agree with klunker and in fact if I were hard up looking for a used Minelab I would not go older than GP Extreme myself. But here is a thread in 2009 touting the virtues of the SD2100 by some people that know. http://forums.nuggethunting.com/index.php?/topic/5759-old-sd2100-setup/ The one comment about old Minelabs varying a lot in performance is also true. All I know is I never did like the "Minelab warble" and as far as I am concerned the solid threshold is the best thing about the GPX series. I am not kidding, when I shut my old units off after 12 hours of detecting I could hear that warble in my ear an hour later. I would not want to go back to listening to that. Same old same old - if you know what you are doing and get out at work at it any of them will find gold. If you do not put the coil over gold, it does not matter which model you own.
