  1. Hello, I have purchased 2 Gold Bug Pro's and an original T2 which I want to use for Gold Prospecting, I am new to metal detecting but my wife and I decided we would give it a go. There is a local gold fossicking area around where we live and we bought a sluice and gold pan and have found quite a bit of tiny gold in the couple of times we have used the pans and sluice. The tiny gold seems too small for a metal detector to pick up, well any of my metal detectors anyway. I have the 5" coil for the T2 and a Mars Tiger along with the standard 11" coil, so which of those coils do you think will be best to find small gold nuggets? For the Gold Bug Pro's I have a Nel Snake, a Cors Fortune and the 10" Fisher coil, 5" standard coil and 11" standard coil. Which coils should I put on the Gold Bugs? Thanks for the help, I clearly have a lot of work ahead of me to work out how to use the metal detectors well to find these tiny gold nuggets but i've been doing a lot of research and have read Dave's Book.
  2. Hi, hoping one of the Gold Bug Pro brains trust could give me their opinion please?I'm new to detecting & was wondering about the ground balance number and the ground phase number in the middle of the screen. In order to ground balance I'm pumping the coil up and down whilst pushing the GG button and most often the ground phase number and ground balance number match closely pretty quickly, however.....once I get started sweeping again the ground phase number (in the screen centre) jumps all over the place. Is this normal? Or should after I've ground balanced, the phase number pretty much remain the same? I've read through the manual and I think I'm doing everything correctly, just not sure if an erratic phase number is right? I was in all metal mode, both dials at 12:00 and up on dry sand. Thank you
  3. Back at the end of 2013 I made a post about trying to choose between the Fisher Gold Bug Pro, Garrett AT Gold, Minelab X-Terra 705 Gold, Tesoro Lobo SuperTRAQ, and White's MXT. The real point I was trying to make was not that any were better than the others, because in my opinion in all metal prospect mode they are all so close as to hardly matter. My contention is that you should choose one based on all the other features included, such as weight, waterproof or not, tones, coil selection, etc. In my case I just wanted a light, simple detector for looking for gold in the middle of ferrous trash. I went with the Gold Bug Pro mainly because of the simplicity of the machine combined with the under 3 pound weight. Since then I kind of went down the rabbit hole. The Makro Gold Racer came along and at 56 kHz versus the Gold Bug Pro 19 kHz and about nearly the same weight it ended up replacing my Gold Bug Pro. Then I picked up a good deal on an XP Deus with 11" coil in anticipation of getting the new high frequency coil. Then the Nokta Impact came along and now the Minelab GM1000 plus there are more on the horizon. Then there is the fact I am a sucker for a deal and an impulse buyer! First Texas started aggressively blowing out some models at exceptional low prices recently, and the temptations for me have been continuous. I sort of missed that Gold Bug Pro and so when this deal on the basic Gold Bug came along at $337 I was really tempted. However, I wanted a larger coil and so I passed. Then along came this smoking discount on the Teknetics G2 for only $390 with free shipping. Or less. The deal is offered by First Texas direct on eBay and they included the "Make Offer" button. I decided to offer $375 and leave it up to fate. If they accepted the offer it was meant to be, if not I would pass. They accepted! Who knows how low they might go? I guess I should have started lower then ramped it up but $375 at half original price seemed quite fair to me. So why the Teknetics G2? Well, it is exactly the same machine as the Fisher Gold Bug Pro (DP 11" coil version) but with a different rod. It sports what is basically the same rod and handle as used on the F75, which fits my hand better than any other I have ever used. Something about the unique design of the handle that tapers to the top and angles forward. And I like the gray color after all the gold and black machines I have used. The main thing is the Gold Bug DP and G2 both come with the 7" x 11" DD coil as stock, giving me that larger coil. I might have preferred the 5" x 10" coil but First Texas only sells that as a stock coil on the Fisher F19 so this was as close as I could get at a great price. (Click on all images in this post for larger versions) Long story short though is to this day I consider the Fisher Gold Bug Pro to be the best starting unit for anyone wanting a VLF for gold prospecting in the U.S. It is nearly as hot as a Gold Bug 2 on small gold but with better depth on large gold, and easier to operate, lighter weight, lower price - just can't go wrong starting out with all that. It is also very popular, and that being the case it is a benchmark detector against which other machines can be measured. With all the new units I have or will have soon I decided I needed the Teknetics G2 mostly to use as a baseline for comparison tests I am doing this year. At the price I got it at if I decide to ditch it later I will not get hurt much, and who knows, I just might keep it. Especially with the second coil I picked up to go with it. The Nokta Impact I have came with two coils, a 7" x 11" DD coil almost identical to the one on the G2, plus a great little 4" x 7.75" (10.5cm x 19.5cm) DD coil. The closest I could get to that with the G2 for comparative purposes is the slightly smaller NEL Snake 3.75" x 6.75" (9.7cm x 17cm) DD coil. Both are epoxy filled and just 0.7" (1.8cm) thick with coil cover. The G2 is a bit nose heavy with that 11" coil but light as a feather with the little elliptical mounted. Anyway, that's my story and I am sticking to it. The G2 will be used in the field alongside the Gold Racer, Deus V4, Impact, Gold Bug 2, Gold Monster 1000, and whatever else comes along over the next year as the baseline test unit. What I often do is overload myself with new models and then let nature run its course. As time goes by I will grab certain ones I like for various uses, and others will tend to sit in the corner. It may not be efficient but it does work for me in deciding what I like to use. And that is the final thought I want to leave you with when it comes to VLF however is this. It is not all about just sheer performance, as these machines are all so hair splitting close these days. That is why each model has thousands of fans on the internet - they all work well. Like a good pair of boots you just have to find the ones that fit you best. At the end of the day the only way that has ever worked out for me is to try them out myself. I will let you all know what I think over the course of the year.
  4. I was advising a guy on a basic machine and Google popped this up. Not sure what it means but Walmart dropped the price of the basic Gold Bug to only $317 https://tinyurl.com/knkwpym This is the model without manual ground balance, ground grab only and 5" coil, that normally sells for $499. Every bit as good as the $649 Gold Bug Pro, just lacks that manual ground balance. At $317.00 I have to fight the impulse to buy one just because the price is so low for a decent machine. They also rolled the $599 Teknetics Gamma 6000 (a coin detector) back to $356, a huge price reduction. With all the First Texas price reductions lately does smell like something is up. Anyway, for a second detector or somebody looking to get into nugget detecting cheap with what I consider to be the best available entry level model, here you go.

  5. Thinking i might trade my Fisher Gold Bug for a Nokta Fors Gold. It is the standard Gold Bug digital not the Pro. What do you all think, good idea or not. I have heard the Nokta is a bit better even than the Gold Bug but have no first hand experience with one. Anyone that has used both cares to respond i would appreciate your thoughts. Thanks
  6. Those that have tried them, which do you find does the best job for nuggets on a Gold Bug Pro, the Fisher 5"x10" DD or the Nel 5.5"x9.5" DD, or some other? Thanks for any input.
  7. Good evening chaps a friend of mine bought some nuggets to try his goldbug and other machines he has in his arsenal and it seems the 5: bel sharp has better sensitivity on the nuggets than the fisher 5" ...did any of you compare both coils??? Thanks RR
  8. On ferrous infested area try to Ground balance on 20 or even 0.......manually try searching in all metal with the sensitivity as high as possible...it also work on wet sand Ferrous will produce double beep and non ferrous a deep loud single beep...excellent in iron infested area even better with a 5" or the 5x10(which is i think even more sensitive) Let me know how you get on with it RR
  9. I am looking for opinions on working a more productive park hunting range with my non manual GB machine. I am currently using the stock 5 inch coil, I had been using a Nels Sharpshooter but have decided it is too much for the trash laden parks here where I live. 1. I have been digging the 44-59 vdi range with the understanding that some jewelry may be slipping away, how off base is this. I will dig a solid 80 and above, not fond of pennies but small silver rings seem to fall in that range. 2.Is there anything of value found in the 60-79 range? 3.Most importantly, vdi fluctuation, how much do most of you with experience allow for. If I get more than a six number swing, 3 up, 3 down, I pass. Is there a rule of thumb for this? Wendell Clark
  10. I was out last week playing around with the Makro Gold Racer alongside my GBPro. I've grown quite accustomed to the "hot spot" on the 5" x 10" DD Gold Bug coil right at the tip, maybe 1.5" back from the very tip, and with the Racer it seems the strongest signal is right dead center on the 5" x 10". All coils have that sweet spot, but it got me wondering why it would differ? I've never dug into a coil and looked at the guts but it would seem to me that they are all pretty similar inside(of the same type of course). In other words, I would assume the inside of both the 5" x 10" DD coils on both detectors would be about the same inside, so why would the hot spot location be different? Curiosity got the best of me.
  11. Hello and thank you - large, for the excellent information. This is pretty exciting for someone who's sighting in on his first detector. I've followed countless threads here and on Tom's forum, and was about to buy a Gold Bug Pro. With experience and a few ounces gained, the intention is to add a gpz or gpx to the quiver. My first detector will be a complementary tool for my placer mine. I hope to qualify and outline pay-streaks in succession with stripping ops. If the detector in question can also help in prospecting some nearby quartz veins, that would rock. Regional geology appears hot, but my definition of hot is no doubt different than a detectorist's. Volcanics, greanstone, pyrite, pyrotite, arseno, tetrathedrite..., and magnetics scattered here and there. With this in mind, would the Gold Racer be a more appropriate tool than the Gold Bug Pro?

  12. I want to start detecting some of the iron trash dumps that I come across out nugget hunting. I currently don't have a detector that can successfully hunt these areas. I have done some research and have narrowed it down to two. The MXT, proven winner and the Racer 2, because I have read good reviews. What I need is the opinion of the users on this forum and if you think there is something else that I should consider, please let me know. I know the Deus excels in this area, but not sure about having to charge so many batteries. Also, I thought I read the coils for the MXT were being discontinued??? Brian.
  13. Strange black wire with paper clip? Guy told me it was junk .... I shook it and heard noise inside.... Found this pleasant surprise flying around in the control housing. Anyone have an idea on this.... I'm thinking they grounded to the coils female wire jack plate and back to the ground plate on ground reject switch... Little help here fixing up for a good friend yard sale special ? 20 bucks. They hurt her though lol seen better days
  14. This question has been in the back of my mind for a while now. If nugget shooting in mild to moderate ground or even stretches of exposed bedrock in a desert wash, how would the 19kHz GB Pro w/stock 10" DD coil perform compared to the 13 kHz F75 w/ 6.5" or 10" concentric elliptical coils? I was going to PM Steve directly with my question but thought forum participation would be better. Thanks for the input,,,,Rob
  15. Hello, I am new to the forum and new to detecting. I have a little over a month park detecting with a couple of flea market acquired Bounty Hunter detectors. I am ready to pull the trigger on a nugget focused detector and have narrowed it down to 2. I am looking at the Gold Bug Pro and the Makro Gold. I live in South Eastern California, I am a half hour away from an area that has proven gold.....small gold. I dry wash occasionally so the Chocolates and Cargos are somewhat familiar to me and close. I am not looking for answers on which detector to buy. I am looking for opinions/pros and cons on the 2 detectors mentioned, given my current inexperience and the area that I will be prospecting. Thanks in advance. Wendell Clark
  16. I'm wanting to get a Gold Bug, with the 10" elliptical coil though. If I get one with the stock 5" coil how hard would it be to sell the coil and what do they go for?
  17. The Fisher Gold Bug Pro is one of the most popular VLF prospecting detectors in use today. I think it is pretty obvious Nokta is gunning for the Gold Bug Pro directly with the new Nokta FORS Gold+ and so I thought a little comparison is in order. The FORS Gold+ comes with two coils, a 10" x 5.5" DD and a 5" round DD. Few people probably know it but the Gold Bug Pro is available as a dual coil package with the exact same two coils, the Fisher Gold Bug Pro Two Coil Combo. Both detectors run at 19 kHz, both available with same two coil package - a direct head to head battle. The best Internet price for the Fisher Gold Bug Pro Two Coil Combo is $749 and the Internet price for the Nokta FORS Gold+ Two Coil package is $679. I prepared a little comparison chart for you here. One thing lacking is that I think the Nokta comes with coil covers and the Bug does not but I am not sure of that yet so left that off the chart for now. And another item I just thought of but am not going to bother changing in the chart right now is that the Nokta does have a concentric coil option while the Fisher is designed to run DD coils only. Concentric coils offer certain benefits in some detecting scenarios like better ferrous discrimination compared to DD coils. I have used the Gold Bug Pro extensively and although I have not used the FORS Gold+ yet I have compared the Bug to the original FORS Gold at 15 kHz. The two models are literally neck and neck on gold nuggets even comparing 19 khz to 15 khz so I have no doubt that as far as detecting gold goes it is going to be a real toss up between these models. The operator will make the real difference more than the machines themselves. The FORS Gold+ however offers more features at an extremely aggressive price so on paper at least it offers an incredible value. A new feature difference is that the Nokta now has a setting they are calling iSAT which is a version of what White's has always called V/SAT. This was a White's exclusive for a long time but if there ever was a patent it has run out. All detectors these days with a threshold based all metal mode are constantly retuning in an attempt to keep the threshold steady over ground variations. This is why if you stop moving the coil the target fades away. The retune rate is normally factory preset and cannot be changed, but White's has always offered the ability to vary what they call the Self Adjusting Threshold (SAT) rate to suit the operator. Slower settings are more sensitive but require slower coil sweeps while faster settings smooth signals out and allow for faster coil movement. In homogeneous ground slower settings will get you extra sensitivity while in variable ground faster settings help smooth false signals. In my opinion however it will come down to what often separates detectors when I use them myself, the intangibles of how detectors sound and how they feel. The FORS Gold+ is a solid pound heavier than the Gold Bug Pro. Surprisingly however if you get a chance to try them both you do not feel it when using the 10" coils because the Nokta is balanced with the underarm control box while the Fisher tends to be nose heavy with the 10" coil. The real difference in this regard is the Fisher "S" rod grip versus the Nokta pistol grip. I can promise you right now some people like S rods and some hate them, and the same can be said of the Nokta pistol grip. You simply can't know unless you get them on your arm for a couple hours. The Nokta does have the edge in the audio department however with multiple tone settings. That does not mean a person still might not like the sounds the Fisher puts out better but at least with the Nokta you can change it to some degree. Finally, there is the large forward facing display on the Gold Bug Pro versus the dual LCD displays on the FORS Gold+. Everything on the Fisher is in your face all the time. Nokta puts the rarely used adjustments in a side display on the control box while critical items like target ID are displayed on a miniature LCD mounted on the top of the pistol grip. In practice both work fine but the Nokta is a bit more awkward in some regards because of this during those times when you actually do have to make adjustments. Ultimately both styles will have fan clubs and detractors but what I like most is choice. More options for us to choose what we personally prefer and that is a good thing. Long story short I think these are both great detectors and it is pretty hard to go wrong with either of them. Both are intended primarily for nugget detecting but can be used for most general detecting tasks. In fact, machines like these tend to be very popular with the relic hunting crowd who are seeking low conductive targets like buttons and bullets in ferrous trash. Anyway, I hope this helps for those who may be considering either of these detectors to sort it all out. More information on the Fisher Gold Bug Pro can be found at http://www.detectorprospector.com/gold-prospecting-equipment/fisher-gold-bug-pro-nugget-metal-detector.htm and more information on the Nokta FORS Gold+ can be found at http://www.detectorprospector.com/gold-prospecting-equipment/nokta-fors-gold-plus-metal-detector.htm
  18. Can anyone tell me what the difference is between the two detectors?
  19. I have now put enough time on all these units to at least reach a basic conclusion in my own mind. And that is that they are far more alike than different. Trying to get clear differences to appear in actual field use in highly mineralized ground is a true exercise in hair splitting. A couple detectors that can be added to the title list are the Teknetics T2 and G2 models. First Texas owns Fisher and Teknetics. The T2 is the predecessor of the F75. They are not exactly the same detector (they do not share coils) but almost identical in performance. The G2 really is just a Gold Bug 2 in different clothes. 13 kHz - Fisher F75 and Teknetics T2 15 kHz - Nokta FORS Gold and FORS CoRe 19 kHz - Fisher Gold Bug Pro, F19, Teknetics G2 In actual use the frequency just about says it all. The lower frequency F75 and T2 are just a tad less sensitive to very small low conductors, like a small gold nugget. The 15 kHz FORS is almost an exact match to the Gold Bug Pro/F19/G2 for sensitivity to small low conductors and so despite the bigger frequency gap I would say the FORS models come closer to the higher 19 kHz models than the lower 13 kHz models. I have to say it all just boils very much down to the feature list, and again, they line up pretty well. The less expensive Gold Bug Pro and G2 have a more limited feature set than the F19. The F75 has the most options for tones and settings at the highest price on the list. The Nokta units at their new lower price are a real good value. For me when it came down to actual performance the Gold Bug Pro/ F19 were so close to the FORS models I let the two Fishers go and kept the Nokta. Basically just to get the automatic ground tracking which can be very useful in variable ground but also the three tone option, which is nice for coin detecting. I also like the way the Nokta units balance better with larger coils. All I can tell anyone at this point if you want a detector to use for nugget detecting and also for other purposes, the Gold Bug Pro/F19/G2/FORS Gold and FORS CoRe are so close in actual field use that it will all come down to the operator and ground variations. I think the machines are a toss up from a performance perspective and so just line up the feature list and go with whatever floats your boat. I think for sheer value at this time the Nokta FORS models are tough to beat. The T2 and F75 give up a slight edge on small low conductors. What this means is that all the previously mentioned models are better for smaller gold nuggets. The trade off is the T2 and F75 are better all around detectors for general purpose use, gaining in coin and other high end conductors some slight advantage simply because the machines are not quite so sparky on tiny non-ferrous trash. In moderate to low mineral ground conditions the T2 and F75 have a clear depth advantage on high conductive coins but in very mineralized ground the advantage is nearly non-existent. In my case at least I feel like there is a 90% overlap between my latest version F75 and the two FORS models. If I head out the door right this second to go hunt coins I am more likely to grab the F75 as I like the extra tone schemes. There is the 3H mode that gives a high tone beep on all normal coins but also takes US nickels, which usually reads as a mid tone, and puts it up in the high tone range also. This is a great cherry picking mode. The standard 4 tone mode is great for cherry picking jewelry digging the low mid tones. I like the big screen and the backlight, etc. So I am also keeping my F75. But if I was heading out the door chasing gold nuggets right now in a really trashy location and not wanting to use a PI, I would grab the FORS instead. It pulls low conductors like small gold nuggets out of the ground better than the F75. Not by a huge margin, but enough to matter to me. And that is where it will stay for now. I am waiting to get my hands on the new Makro Racer models this summer, and using the F75 and FORS plus Racer units all summer. Then proceeding to phase two of the weeding process. I am trying very hard to get my detector collection down to just a couple PI detectors and a couple VLF detectors. It is down to that stage of the game however where it just needs a lot more in field use to let things sort out for me. What I can leave you with for sure right now however is that these are all very good detectors that are ridiculously close in performance. You really just can't go wrong with any of them. Mid frequency VLF technology has matured to the point where it is almost impossible for anyone to really stand out from a performance standpoint. Nearly all the performance debates I see on the internet about these models boils down to differences in ground mineralization more than the machines themselves. Just find one that feels right on your arm and sounds good to your ear and get to work! This is very much a work in progress and so as I get a chance to use the large coils or hunt under different ground conditions if I come up with anything if interest I will add it here. There is a related thread on VDI numbers and tones at http://www.detectorprospector.com/forum/topic/526-fors-gold-f75-v3i-tone-and-vdi-tidbits/ For detailed information on each model plus the latest prices visit Steve's Guide to Gold Nugget Detectors
  20. I got my hands on a prototype of the new Fisher F75 and was very impressed with the improved EMI (ElectroMagnetic Interference) resistance more than anything. I also liked the new ferrous tones option that allows the operator to set the volume of the ferrous tone lower than the tone from non-ferrous targets. This makes the non-ferrous targets stand out better and is less fatiguing to listen to. The new FA fast mode is something I do not need as much as some people. It is intended to improve separation of adjacent items while detecting. For me I had sold my previous F75 for no other reason than EMI issues and let it go in favor of my Gold Bug Pro, which is exactly the opposite when it comes to EMI. The big attraction for me in the new F75 is the EMI resistance. I had to send the prototype back but was told I would see a production unit eventually. I must have been last on the list because it kept not showing up. Questions raised in the meantime really got me to wondering about things, so while I was waiting I found a deal on a never used 2013 F75Ltd version 7.0A. I figured it would give me a baseline for comparisons to the new unit when and if it ever arrived. Recent posts also got me wondering about the new Fisher F19, and on an impulse I picked up one of those also in like new condition. So I am sitting around playing with these two detectors when my new 2015 F75Ltd2 shows up a few days ago. Only one problem. The ground is frozen here. Now, I would love to say I went out and tested the heck out of these three detectors, head to head, under stringent test conditions, witnessed, verified, and on video. Given the circumstances it seems almost criminal not to. The reality is however that I am about burned out on the whole Fisher upgrade saga and just wanted to make a personal decision and move on. I do not feel like waiting around for the ground to thaw. The F19 is a sweet little detector and does hit tiny low conductors better than the F75. The new F75 seems just marginally better than the 2013 F75 in that regard but still not as good as the F19. Since I have other machines that trump them all for small gold I decided what really mattered to me was larger item performance and overall features so the F19 got kicked to the curb. My only real issue at that point was trying to determine if there was anything about the old F75 versus new F75 that would make me hesitant to upgrade. Again, I wish I could give you some kind of in depth report but I think I have learned my lesson reporting on machines where I have got one for free (sort of). The extra effort is kind of wasted so all that really matters is satisfying myself. I bench tested as best I could and the simple take away for me once again is the new F75 is remarkably more stable and interference free at higher gain levels than the old F75. I noted no significant loss of depth in all metal mode or anything else to cause me concern. I may very well have missed something, not saying I did not but it does look like I got a properly functioning F75Ltd2. I have decided I am happy with the new detector and that it is time to move on. I am getting pretty busy with getting ready for the prospecting season and in fact am headed to BLM right now to spend the day on claims research. So for what it is worth it is new F75Ltd2 for me. If anyone is interested in like a like new F19 or F75Ltd they are both for sale at http://www.detectorprospector.com/forum/classifieds/ The F19 I am including my 5" and 11" DD coils from my Gold Bug Pro that I held onto just in case the F19 ended up being the keeper. They can go now also. It really for anyone interested comes down to Fisher F19 vs Fisher F75Ltd2. From a prospecting perspective it is a no-brainer. The F19 is everything a Fisher Gold Bug Pro is along with some extra features like a backlight some people may like. It would be a bit better than a Gold Bug Pro at getting nuggets out of a pile of nails. The key issue is the F19 comes with the coil the Gold Bug Pro should come with but does not - the 5" x 10" DD coil. To get a Gold Bug Pro with that coil will cost you almost as much as just getting the F19 anyway, so I would tend to push people towards the F19 over the Gold Bug Pro for that very reason alone. I also for gold prospecting would recommend the Gold Bug Pro or F19 over the F75. These two models are slightly hotter on little gold nuggets than the F75 and for quite a bit less money do everything a gold prospector might want. So why am I going with the F75 myself? The reality for me is I have other detectors I will use if I am chasing small gold nuggets. They would be the Fisher Gold Bug 2 for low mineral ground and Minelab SDC 2300 for high mineral ground. Having these two detectors makes my having the F19 or Gold Bug Pro overly redundant. What I am more interested in is a good VLF for looking for larger gold nuggets in trashy tailings and cobble piles using a larger coil. The F75 is slightly better suited for this task than the F19 or Gold Bug Pro but more importantly for me it is also a good urban coin and jewelry detector, especially with the new resistance to electrical interference. It used to be the big weakness in the F75 was urban use, and all of the sudden that is now a strong point for the machine. I am glad to have put that all aside as the whole F75 thing has been dragging on for far longer than it should have. As seems to be usual for Fisher these days they need a bit of time to sort things out when they release a new model or even an upgrade to an old model. At this point it is probably safe for anyone wanting a new F75Ltd2 to get one or if they have an older model and want to have it upgraded I also think things seem to be sorted out on that end also. Those who are interested in upgrades can get details at http://www.fisherlab.com/hobby/upgrade.htm
  21. I was out hunting some dredge tailings yesterday and did some testing with the SDC 2300 and the Gold Bug Pro on some specimens. I tested a variety of pieces but the one that is most interesting is in the pic below. I previous tested this with the GPX 5000 with standard 11” mono and it registered only very slightly when touching it to the coil. The GB pro with the 6x9 coil in all metal mode will easily pick this up at 8”-9” in an air test. The SDC in an air test was slightly less at 7”-8”. I then put this at the bottom of an 8” hole without covering it up and retested. No change on the SDC but the GB was now barely able to pick it up. After filling the hole the SDC still had no problem but I couldn’t pick it up at all with the GB. Further testing determined that the GB would pick this up at only about 4”-5” when buried. I actually found this specimen about 4” below the bottom of an 8”-10” hole where I dug out a large square nail. Other observations were that on the buried test the GB was only slightly deeper in all metal than in disc. mode but the target response area is far greater in all metal. In all metal I tested with the machine ground balanced neutral and with ground balance at + 10 and – 10 on the GB screen. Also if I put one of the numerous hot rocks from the tailings over the specimen it almost completely masked it. After this test I carefully covered over a 15’x20’ area with both detectors from 2 directions and marked all targets. I got 7 targets with the GB and 9 with the SDC. The 7 with the GB were all seen by the SDC but the GB could not see the other 2 SDC targets. 6 were square nails and one was a small piece of tin. The 2 the SDC saw that the GB did not were a small (about ½”) tip of a rusty square nail at 4” and the item in pic 2 below at a about 6 1/2 inches. Not certain what this item is. Looks like some kind of melted metal possibly solder. It reads on the GB screen about the same as gold or lead but too hard to be lead. This screamed on the SDC and once out of the ground hits very hard on the GB also. I reburied it at about the same depth and the GB hit it fine. It seems that there are certain situations or rocks that mask targets from the GB. Last observations are that the GB seems much more sensitive to iron targets than the SDC. The deeper nails were stronger signals on the GB but on the specimen in the pic and some heavier gold specimens I tested the SDC clearly had significantly more depth in the ground (at least 25% - 30%). Bottom line the SDC will clearly potentially find more specimens than the GB in tailings if you have the patience to dig every target but with the amount of trash in the area I was hunting it would be difficult to have the discipline to dig all targets. I have gone out many times with the intention of digging everything but after 3-4 hours of digging junk ever couple of feet I usually fall back to using the Disc. to try to determine if its trash. Given the random distribution of specimens in the tailings this is most likely gives the best overall odds but that being said I have found a couple of nice pieces that in ground read and sound just like nails on the GB pro (Target id only in the high 20’s in disc. and 3 or more bars on the iron indicator in all metal. Once out of the ground or reburied they read in the normal 48 to high 50’s range in disc and 0-1 bar on the iron scale in all metal.) I am trying to video as many digs as possible to try to catch one of these to post showing the sounds and readings. It would be great to get some of the groups opinions on the reason for this.
  22. While out on the Sawtooth adventure, Dee tried a GB Pro 5" coil on her F-75. Guess what.... it worked! Steve, any comments about that?
  23. Hi. I bought a couple of gold nuggets from a guy that needed some cash. Out of curiosity and I guess peace of mind I ran them over the coil of my Gold Bug Pro. One came in around the low 50s like the rest of my nuggets I have found but the 6.6 gram solid nugget came in from 68 to 72. Is that a little high for gold? Thinking its because its bigger than any nuggets I have found in the past. The other nugget I bought is 6 grams and comes in at 52 but it is not solid. It is more of a crystalline type nugget. Very pretty.
  24. Fisher Research originally released the 19 kHz Gold Bug model about 1987. It was a real breakthrough design at the time with a compact control box, S-rod, and elliptical coils. The detector is a good unit but is strictly all metal (no discrimination). It has no LCD readout and looks much like the current Gold Bug 2 but has a white lower rod and a black control panel face. Some people are confusing this old model with the new so be aware of this when looking at used detectors. The 19 kHz coils for the old Gold Bug will not work on newer versions of the Gold Bug below. Around 2010 a number of new Gold Bug models were released by Fisher. First came the Gold Bug. Then came the Gold Bug SE (Special Edition) which added manual ground balance at a bargain introductory price. The SE with minor tweaks later became the Gold Bug Pro at a higher price. So now we have two basic versions, the Gold Bug and the Gold Bug Pro. They differ from the old 1987 model by having an LCD readout. The standard version of either detector comes with a 5" round coil. There is a Gold Bug DP (Deep Penetrating) which is nothing more than a Gold Bug Pro with an 11" x 7" DD elliptical coil instead of a 5" round DD coil. The only difference listed by Fisher between the Gold Bug and the Gold Bug Pro is that the Gold Bug Pro has a manual adjustment option for the ground balance and also offers "higher sensitivity". Both models use a "Ground Grab" button as a simple ground balance method that is quite effective. The Gold Bug Pro allows you to also manually adjust the ground balance setting up or down. The manual adjustment can be used in conjunction with or separately from the Ground Grab button. The big question is the "higher sensitivity" claim. There are two possibilities here. First, that the Gold Bug Pro actually allows for higher gain or sensitivity levels. However, I was in marketing too long and have a more jaded thought. Manual ground balance allows for a higher degree of control that if used properly can get you more sensitivity. There is a very distinct possibility the higher sensitivity claim follows directly from the ability to manually ground balance the Gold Bug Pro. This could be tested with both units set side by side with identical ground balance settings and max gain. If the Gold Bug Pro is inherently more sensitive an air test should show it. I have not had the chance to do this my self but if somebody wants to there you go. My opinion? I believe the Gold Bug and the Gold Bug Pro if outfitted with the same coil are basically the same detector. The only real difference is the manual ground balance option on the Gold Bug Pro. Do you need it? Not really, and especially when you consider that for $499 vs $649 that is probably all you are getting. The Ground Grab function is remarkably effective and would suit most people just fine. I personally do like manual ground balance and so for me spending the extra money to get it is a non-issue. I do as a rule tell people that if cost is not an issue get the Gold Bug Pro. It is far more popular and would be easier to resell. But in all honesty I think the Basic Gold Bug is the real bang-for-the-buck unit. There is nothing else close to it at the $499 price point that offers full LCD readout target discrimination while in full power all metal prospect mode. I should note that First Texas owns both Fisher and Teknetics. The Fisher Gold Bug DP (Gold Bug Pro with 11" coil) is marketed by Teknetics as the G2. The Fisher Gold Bug DP goes for $699 and the Teknetics G2 is $749. The $50 extra gets you a pistol grip rod instead of the Gold Bug S-rod and an arm strap. Nice gray paint scheme also. Really boils down to pistol grip vs S-rod, purely a personal preference thing. I use the 5" x 10" elliptical myself and consider it to be the best all around coil for the Gold Bug. However, right now you have to get it as an accessory or as part of a two coil package. Fisher would be doing us a service to release the Gold Bug with this coil as standard on the unit. My Gold Bug 2 is slightly better on the tiniest of gold but the Gold Bug Pro easily outperforms the Gold Bug 2 on larger nuggets at depth. For all around nugget detecting the Gold Bug or Gold Bug Pro (and G2) have a better balance of both small gold and large gold capability than the Gold Bug 2. To recap first came the original 1987 era Gold Bug with knobs and switches: Then about 2010 we got the new Gold Bug: Followed quickly and briefly by the Gold Bug SE. Note how the plus and minus buttons now have dual functions, both Disc and Ground Balance, compared to the basic Gold Bug above: The Gold Bug SE was basically the prototype for the Gold Bug Pro, which got a new faceplate decal and a higher price: And finally, the Gold Bug Pro was also marketed under the Teknetics line as the G2 with a different rod/handle assembly: Gold Bug Pro DP compared to Teknetics G2:
