  1. Hi GeoJack, Welcome to the forum! Can you post a picture of the cover? I have not seen one posted anywhere yet and no mention on Garrett website. Was this a US purchase? I got the impression maybe Australian dealers were including the scuff cover because so far that is only mention I have heard of it so far. I am wondering if it is now officially included with the ATX or if it is a dealer add on.
  2. Hi Rick, As I alluded to at http://www.detectorprospector.com/forum/topic/45-lots-of-gold-found-with-the-whites-tdi/?p=488 any PI detector will not do well on porous specimen gold. In theory you could have a one ounce specimen and if the gold is perfectly dispersed through the rock a PI detector will not pick it up. You saw my GPX 5000 find nothing until I switched to my GMT to get a couple small specimens. The TDI has the same problem. There is no way of knowing exactly how specimen gold will react. It just depends on how much the gold is lumped up in the rock. You need a solid mass in there somewhere. Until they make a detector that can do everything in places like you have you pretty much have to hunt everything at least twice - once with a PI, and once with a hot VLF. Specimen gold reads the same as a hot rock to a PI. What makes a PI great is it ignores most hot rocks, but you lose some gold in the process. It is possible to make a PI that will hit the tiny gold or specimen gold, but then it would also act just like a VLF detector and hit hot rocks. It is all a trade off and there is no free ride. If it makes you feel any better I have faith there is big stuff in your area it will take a PI to get, but they are very rare. So hunting a day or two and finding nothing is just the way it is. A hot VLF will get more finds more regularly where you are.
  3. Great specimen Gus! Just proves something I used to teach in my mining classes. Half the battle is in what you sell the gold for. I can find half as much gold as the next guy but be doing as well if it is worth twice as much.
  4. I always have my ears perked up for something new in metal detectors and metal detecting technology. I’m not educated enough to really get deep into the technical side of it, but I have a general layman's knowledge of the subject. A couple years ago Carl Moreland, the Engineering Manager for White's Electronics, was interviewed on a radio show. I tripped over a reference to the interview on another forum and checked it out. It is very long, and near the end Carl dropped a bombshell. At least I thought so, but it went unnoticed and uncommented on in the metal detecting online world. I thought about posting it on a forum back then but decided to wait and see what developed. Here is the applicable portion of the interview: Relic Roundup Radio Show, January 17, 2012, Interview with Carl Moreland, Engineering Manager, White’s Electronics http://en.1000mikes.com/app/archiveEntry.xhtml?archiveEntryId=260469 Transcript beginning at 50:57 mark: Carl Moreland - “I can mention one technology that we’re working on because the patent has already been published… or the application, not the patent hasn't gone through yet. We’re working on something called half sine technology, which has actually been around since the 1960’s in geophysical prospecting applications. This is where instead of transmitting a sinusoidal signal you actually just transmit half of the sine and you can do that at extremely high voltages and high ? rates and so on. It’s technically not pulse induction but it’s not VLF either and it is a time domain method. And with that we can get really good depth and we can even get target id information and do discrimination and so forth.” Can you see why I perked up at that? I am still amazed it did not get any notice at the time. Nothing happened for a long time. Then I got this PM from Rick Kempf recently: Sent 29 January 2014 - 09:04 AM Was looking for info on my new SD 2100 this AM when I sort of fell down a rabbit hole of old forum posts and emerged reading Whites new patent. About the first thing I noticed was that you were cited in "prior art". Here's what they cited: http://www.voy.com/76600/7/475.html The patent is here: http://www.google.com/patents/US20110316541 Is this something you knew about? Just wondering. Rick Kempf I told Rick, yeah, heard about that. It was the patent finally being granted from the application Carl mentions in the interview. It was fun getting a mention in a patent though I think it was just the examiner studying up on the subject and finding my old post helpful in simplifying the subject. For a long time the Holy Grail in metal detecting has been something that combines the target identification of an Induction Balance (IB or more commonly known as VLF) detector with depth of a Pulse Induction (PI) detector. There have been many promises and false starts over the years, and that was one reason I kept the radio interview mention quiet the last couple years. Frankly, I had half forgot about it until Rick brought the patent being granted to my attention. Notice the title: Hybrid Induction Balance/Pulse Induction Metal Detector A new hybrid metal detector combines induction balance and pulse induction technologies. Target signals are generated from a transmitted wave that has both induction balance and pulse current inducing characteristics and uses pertinent sampling of the receive data. Combining the two data sources provides eddy current target identification while excluding ground permeability and remanence obscuration. Is it time to sing Hallelujah? Well, there is a big gap in between getting a patent and bringing a detector to market. Many patents get filed and you never even see something directly related to the patent. Maybe it looked good on paper but does not pan out well in reality for numerous reasons. So just because White's was granted this patent does not mean something is around the corner. However, they have been working on it for over two years already obviously. And it has been some time since White's put something new out. I do not count remakes of the MXT etc as new. So I think there is reason to be hopeful we may see something one of these days. John Earle is one of the unsung heros in the industry. He had a hand in many of the best products at Compass Electronics before moving over to White's after Compass went under. To this day I have never used a VLF that goes any deeper than my old Compass Gold Scanner Pro. John was one of the brains involved in that, as well as the White's Goldmaster 3, regarded by many as being the pinnacle of the analog development of that model line. I was fortunate to have met John at the factory some years ago. He is listed as the inventor on the new patent. Half sine technology is also mentioned in an earlier patent filed by White's, again with John listed as inventor at http://www.freepatentsonline.com/7649356.pdf Looks like serious stuff brewing. Bruce Candy of Minelab makes mention of half sine technology in a patent application at http://patents.com/us-20130154649.html which makes me wonder about the new "Super Gold Detector" he is working on. But it is this most recent patent by White's that seems to put the finest point on it. Maybe the Holy Grail of detecting is soon to be a reality. The fact it is White's certainly gives me more hope than what we have seen in the past. Edit May 2015 - see also White's patent for Constant Current Metal Detector
  5. Hi Cliff, I enjoy two things about metal detecting. The actual going metal detecting for stuff part is the real fun part. But I also just like learning about new detectors. It is fun figuring out what each model does best. So I do have a tendency to get infatuated with new detectors. A simple case of Stevie gets a new toy. I find PI detectors to be more challenging than VLF detectors and so the ATX is right up my alley. GBPI detectors have always been clunky, heavy beasts, but in the ATX I see the potential finally for a PI that is more in line with what people expect from a VLF. The ATX runs more like a VLF than a PI, just with different operating characteristics. And it could obviously be put in a package weighing under 4 pounds. I do not know who will do it first but I can see that a light weight high performance GBPI is now just around the corner. Garrett can do it first, the question is will they?
  6. Hi Ray, Hope you do not mind, I edited the title to give a better indication of what the thread is about. Great stuff, thanks for posting!
  7. I try to use rechargeables as much as possible but use alkalines for backup and around the house enough it seems I always have these batteries sitting around. I usually replace batteries in my detectors well before they are dead, so keep them to use in flashlights etc. until they really are used up. I decided I needed something simple that would test any size battery with no fuss to sort out the good from the bad. I've been using a little multimeter but wanted something simpler. I found the La Crosse battery tester on Amazon and it has been perfect for me. I rounded up every loose battery I had and it makes it very easy to just drop them in and test. AAA, AA, C, D, and 9V are all easily tested as good, bad, or somewhere in between. At less than $10 for a pocket sized tool it has been proven a real bargain for me. Anyone else got a great battery tester to report on?
  8. Nice stuff! Welcome to the forum. Sorry about the lost post. I do my long ones up on a separate program and copy and paste when ready. Kiwi gold?
  9. I updated my page at http://www.detectorprospector.com/gold-prospecting-equipment/minelab-sdc-2300-waterproof-gold-nugget-detector.htm to include the latest information on the SDC 2300. Questions I have. The SDC has a theshold control but no mention of a volume control? The F3 Compact operating manual also mentions no volume control. The supplied dry land headphones and underwater headphones have no volume controls. So is there a volume control? I do not see how there can't be but if so it is being kept secret. Related question - will a headphone adapter be available to allow you to use your favorite headphone?
  10. OK, this from my post at http://www.detectorprospector.com/forum/topic/102-garrett-atx-review-beach-detecting-in-hawaii/ "I may as well relate now that I did have issues with sand in the twist locks but not as bad as anticipated. The lower two twist locks seemed just loose enough that at the end of every outing I just worked them back and forth and the rod in and out and they cleared. But the upper one gave me problems. It got sand inside that refused to come out, even after taking it off and working on it under running water for a half hour. For some reason that upper most twist lock was just a bit tighter to start with and the sand would not clear out. Yet it never quit 100%. I lost most of the ability to twist the lock but it still twisted just enough to hold the rod in place. I am asking Garrett for advice on where to drill a couple holes or maybe slots to see if we can get these things clearing sand a bit better. Overall I actually am ok with them but they need improvement. In other types of sand it could be a big problem. I am going to see if I can get my upper lock to loosen up similar to the lower two and will report back later. The rod assembly got scored up quite a bit from being extended and collapsed with sand in the assembly. I will post photos later. Nothing that bothered me but some might hate seeing their expensive detector getting ground up like this." I have a Water Pik and tried blasting sand out of upper lock ring. Some more came out, but still not getting full travel. I let it dry completely, and tapping and working it fine sand is still coming out and still not getting full travel as I twist the mechanism. Weird, as like I said in the post the lower two locking rings were no problem at all.I contacted Garrett about the rod scuffing because I was concerned about water infiltrating the fiberglass. Some fiberglass is only sealed on surface and once the surface coating breaks water can get into the fiberglass. Garrett said this is not a concern with the fiberglass rods. There is no requirement to treat or seal the surface. Applying something like Armor All may actually cause problems by making the surface too slick for the locking cams to grip well. Bottom line is it is just a cosmetic issue. The rod locking rings is more than a cosmetic issue. Obviously it only affects water users, but this appears to be a pretty good segment for the ATX. I am going to work on mine some more and report back. Garrett recognizes the issue and has produced a good video on the care and cleaning of the ATX.
  11. The pay to mine was pretty consistent at about 75 ounces per year into visitors pockets. So over the six years visitors took home close to 500 ounces total. About 100 ounces of that was in eight nuggets. I understand the desire to believe that a $2100 detector equals a $5800 detector in performance but I am not one of those that share that belief. I am a big fan of the Garrett ATX but if I was headed to Moore Creek tomorrow to look for the big nugget everyone else has missed and could only take one detector, I would be packing my GPX 5000.
  12. As many of you know I owned the placer operations at Moore Creek Mine in Alaska for many years. We ran a very successful "pay-to-mine" operation there. I am still an owner of the lode portion of the property but sold the placer and pay-to-mine operation in the winter of 2009. As part of the deal with the new owners I was to run the first week of the pay-to-mine with them on hand to show them the ropes and ease the transition. Gerry McMullen of Gerry's Detectors booked a group in the first week of 2010, my last week of running the show. Real nice group, and some very proficient operators, a guy named Spencer among them. It was a great week with a pile of gold found, but like all good things had to draw to a close. On the last day everyone was out looking one last time, and Spencer got a signal directly across the pond from the camp in an area where quite a bit of gold had been found in the past. The little pile there was pretty well mowed flat, but Spencer got a nice faint low tone target. He dug. And dug. And dug. Now to his credit he knew there was also some deep trash in the immediate area, and the tone was more likely to be junk than a big nugget. And he was tired. But he came over to the camp and borrowed a long handle shovel and went back to it. It was his last target and he was going to finish it. I am in camp and I hear some whooping and hollering. Spencer hit the big time! He had dug a lot of gold in his nugget detecting career, but the nearly one pound nugget he had just found blew away his previous finds for size! It is always fun being around something like that. The excitement is infectious. I went over to see the hole and frankly it was amazing. We all sat around taking pictures and here is one I got of Spencer standing in the hole the nugget came out of. The nugget weighed in at 11.88 ounces. Spencer with 11.88 Ounce Nugget at Moore Creek, Alaska (click on photo for larger version) The nugget was found with a Minelab GPX 4500. There was over 30 ounces of gold found that week and Spencer's was one of the larger ones ever found in my years at the mine - it was nice to go out with a bang. Spencer really earned that nugget though, many people would have decided it was a can and walked away. More about Spencer Sadly the new owners were not able to keep the pay-to-mine going. Hosting people in the middle of nowhere Alaska is not for everyone and 2010 was the last summer people could pay to visit the mine. The owners shifted to a pure mining operations and were successfully operating through the end of last season. I may stop out and visit them this summer. Has to be another big nugget lurking at Moore Creek!
  13. Before Carl Moreland was Engineering Manager at White's Electronics (and now First Texas), he created a website that has more technical information on metal detectors than any I know of. The Geotech website has lots of interesting stuff and in particular it has a lot of "build your own" metal detector projects for the electronically minded. I have never done this myself but if you were ever curious about what makes detectors tick a lot can be learned here. Projects http://www.geotech1.com/cgi-bin/pages/common/index.pl?page=metdet&file=projects.dat Info http://www.geotech1.com/cgi-bin/pages/common/index.pl?page=metdet&file=info.dat George Overton & Carl Moreland, co-admins for the Geotech web site, also wrote the new book, Inside the Metal Detector. This is not another "how to use a metal detector" but rather a look inside to the operating principles and electronics that make a detector work. Inside the Metal Detector explains theory and offers numerous experiments and projects that demonstrate the theory. You can build an off-resonance pinpointer, a GEB-discriminator, and a microprocessor-controlled PI detector. Even if you're not inclined to build a detector, the concepts learned from ITMD will help you better understand how your own detector works and what all those controls are really doing. The book can be purchased as paperback or Kindle format on Amazon
  14. I welcome and indeed encourage links that are informative. Probably the main reason I started this forum was wanting to post something on another forum and being told "no, that is against the rules". I think it is an insult to people's intelligence to pretend other forums and websites do not exist. The only thing I will stop here is obvious spam. I have no problem if you see a good deal on a dealer website or on eBay and want to post it. eBay in particular has some killer deals on used stuff sometimes. If somebody sees a great deal, post it. I may want to buy it! Evan works for Big Boys Hobbies, a reputable dealer. Bert by all accounts is a real customer oriented guy. Coincidentally I was looking for a new water digging scoop recently and ended up buying it from Big Boys Hobbies, my first purchase there. Very easy purchase and quick delivery. Evans main website at Gonehunting for History is worth a visit http://www.gonehuntingforhistory.com Anyway, I appreciate the link Rick. Very interesting. I have a bit too much of the dig it all mindset sometimes and as a result have not been learning all I could about the discrimination feature on the ATX. It is the best iron discrimination system on a PI detector in my opinion from what I have seen so far. Here is a video put out by Garrett on the ATX being used at a very popular relic hunt in Virginia
  15. China is poised to snag the title of the world's biggest gold buyer, a feat that could support prices of the precious metal as well as accelerate the global bullion market's shift eastward. Gold purchases by Chinese consumers jumped 41% last year to a record, according to data released Monday by the China Gold Association. China has long had a cultural affinity for precious metals, and the increasing affluence of consumers there, along with more relaxed investment restrictions, has boosted the country's demand for gold bars and jewelry alike. The increase was enough to overtake India, which for decades, if not centuries, held the No. 1 spot, according to estimates from several analysts.

  16. Hi Keith, TDI and ATX, what to do? I like the fact I can hip or chest mount my TDI but that is not enough. So right now I am holding on to my TDI for three reasons: 1. I can shut the ground balance completely off, and in ground that permits this it is a very powerful detector. I plan on doing a pretty extensive run of my ATX in default ground balance minimum mode against the TDI with ground balance off to see if the TDI has enough extra advantage if any in that situation to warrant holding on to it. Intent there is mostly hunting in sand. 2. For coins in trash, I can shut low conductive signals completely off with TDI, a very nice feature for coin hunting trashy sites. However, while the Infinium drove me a bit batty with audio barrage there is something less harsh about the responses on the ATX that make it more tolerable. So I am going to do a serious park hunt or two with both detectors along hunting and marking high conductive targets to see how it goes. One small problem with shutting low conductive tones off on the TDI is that mixed tone trash items are more likely to trick me, though I have learned usually to switch to all tones for a double check before digging. 3. I need to experiment more with the TDI ability to completely reject ferrous targets. Depth is lost, but how is it for target masking, see through, etc.? There is one weird factor. The ATX is cool looking. I was surprised that my wife thought it had a good look to it. When she says something positive about how a detector looks it means something. Certainly if I had to choose right now between the two the ATX would stay and the TDI go. I want to take real advantage of having both on hand however to learn more about both so am in no hurry to make a decision.
  17. Low water is good for gold snipers. This article highlights how the recent drought, while bad in many respects, has a silver, or should I say gold lining for prospectors. http://www.wbur.org/npr/273051178/prospectors-see-a-golden-lining-in-californias-drought
  18. Infinium 10 x 14 inch Coil Cover PN: 1606400 Like Ken said this hangs out on each end. There is supposed to be a fitted coil cover for the ATX stock coil out now but they seem to be a secret, not on the Garrett website.
  19. Hard to go wrong with the Gold Bug Pro. The AT Gold is for if you need to put it in the water. Any detector can be used in the rain. I have detected in rain for many a day with lots of detectors. Just drop a plastic bag over the control box, left open on the bottom to breath. A sandwich bag works great on the Gold Bug Pro. The orings on the AT Gold are tough so no reason to worry about failure. They are silicone lubed though and care must be taken to keep them clean. The tiny pins in the coil and headphone connectors are what you worry about. They get bent easily if you are not careful. Bottom line is the AT is a fine machine but I would only get one for prospecting if I needed to submerge it.
  20. There was a recent find of a 117 ounce gold nugget in the Mt Monger area, south-east of Kalgoorlie-Boulder, Western Australia. Unfortunately so far I have only been able to find one very poor photo of it. What's up with that? The nugget is a bit different in that it is pretty long at 20" and narrow instead of a round lump. http://au.news.yahoo.com/thewest/regional/goldfields/a/20549863/faith-of-colleen-on-loan-to-museum/ Anybody have more information on how it was found or a better photo? I did find a photo on Facebook purporting to be the same nugget but I do not think it is.
  21. Hi Merton, Discrimination, whether it is classic discrimination circuits or ground balance circuits really tend to be hard on gold nuggets since gold nuggets respond so close to ground responses. If you totally suppress the ground or the hot rocks lots of gold gets suppressed also. Nature if the beast unfortunately. By allowing more "noise" i.e. more ground noise or hot rock responses the signals from some gold can be enhanced. It is a direct trade off and balancing act as to what works best. Frankly, I run quiet until I hit gold, then tend to get progressively more aggressive in the tuning on a known gold location as it plays out. Sort of a desperation play as I have to dig some hot rocks or hot spots in the ground but it almost always gets gold I missed before. For whatever reason though sounds like you are on the money - the unit is not recovering from the rejection of the hot rock as fast as it should. You obviously have an analytical mind that will serve you well working with the XP especially given that you have a Gold Bug Pro to compare to. Seriously, you should email the manufactuer with your observations and volunteer to test new software versions. I do that sort of stuff, it is fun, and can get you a free detector now and then!
  22. Wow, excellent report Merton, thanks! I was not aware of the hot rock notch on the XP DEUS. Sounds like an advanced version of what a Tesoro had on the old Diablo uMax, and an excellent idea. I have wondered why it did not catch on. Ground balancing is just another version of a discriminate circuit and the ability to adjust out two or more points on the scale would be quite valuable. Sounds like they have some good ideas but as you note they need to work with somebody like you on improving the gold program. I am sure they would listen to your feedback. Valuable stuff.
  23. Hi Rick, It was my best outing ever water detecting. But the cold water of Hawaii and rough surf is keeping the ladies from getting into the water as much. My rings from Hawaii over the years include few women's bands, and not from lack of getting small rings. I have no problem hitting little toe rings and such. Like I said, it is all about site selection. I told my wife we need to go someplace with warmer water and a more affluent clientele. She is game of course. Those days I do not feel like it she is always like "get your butt out there and find me a ring!" You are welcome for the book. Hope it helps. The TDI is a good detector. I am not ditching mine yet just because I got an ATX.
  24. Thanks Kenny. A problem I face is I am very passionate about my metal detecting and I can get pretty excitable over things. So I am making more effort to temper my posts to try and not make detectors appear to be something they are not. Not to pat myself on the back but I am very good at detecting and work hard at it. I can make almost any detector look really good, but it honestly is less the detector and more the person using it. That is a basic truth of the metal detector world that often gets overlooked - it is the operator that makes the detector, not the other way around. Just getting a good detector in no way assures that a person will do well metal detecting. It is all about knowing your equipment, site selection, and hard work. Although I was involved in detector sales for much if my life I never had to sell a detector. What I am really doing is selling metal detecting. I think it is one of the most exciting, fun, and truly challenging things a person can do. It can lead a person on adventures all around the world and bring you face to face with the most fascinating people. Detecting cuts across all walks of life and when you put a dozen true enthusiast together you will be amazed at the variety of people and what they do in "real life". Metal detecting has been incredibly good to me and I really enjoy sharing the passion I have for what for me is not a hobby, but a way of life. If I can turn just a few people on to what I have enjoyed my entire life I will have paid back the many people who helped me along when I had questions and needed help. The bottom line therefore is to not run out and buy a detector because I had success with it but to read between the lines and look at what it is I am really doing. I am out metal detecting and the detectors are just a tool of the trade. There are many, many fine detectors on the market now. We are blessed with a multitude of great machines. Part of the fun is learning about new detectors and what they do best, and they all are pretty good at something. Thanks to the Internet we can share that knowledge freely with people all around the world. It is a far cry from the day when I was a kid in Anchorage with a metal detector and nobody to talk to about it! Thanks for reading and sharing.
  25. I bought a Radio Shack rechargeable headphone at one point and it worked fine, as I am sure most wireless headphones would. My CTX 3030 came with a wireless headphone module. It is one of those great ideas that have not stuck with me. The problem is it is just another thing with a battery. Common scenario is I decide to go detecting, did not charge the wireless headphone module, and am not sure it is fully charged and will not go dead on me. So I grab my regular headphones instead. I have several sets of headphones which stay plugged into whatever I am currently using. Just grab and go. The headphone cord except in extreme situations (diving into thickets) does not bother me. Bottom line is I find myself just using my regular headphones even with the CTX. I suppose I should make the effort to use the wireless but the word I just used, "effort", is why it is not happening.
