Adding select discontinued models now. Added.... Garrett Infinium Makro Racer Minelab Eureka Gold Nokta FORS Gold

The why of it is simple - you are reading things into the careful gaps Minelab leaves in their advertising. I am not reading it the way you are, and so I am not offended because I do not feel I am being mislead. You are reading something else into it and feel unhappy because you feel you have been mislead somehow. It all boils down to debating perceptions of what you think the advertising means as compared to what is really going on under the hood. Since you don't 100% know what is going on under the hood, you just don't know. All detectors are transmitting on at least one primary frequency and many harmonic frequencies. This can be determined with a scope and if you count harmonics it is just a matter of picking a number you want to advertise when it comes to transmitted frequencies. You have no idea how many are being processed unless you know the processing algorithms. This back and forth with Minelab and the others has been going on for years. Garrett picked 96 frequencies for a Garrett Infinium ad as a direct poke at Minelab. How many people thought the machine was really transmitting and processing 96 frequencies based on the ad? It is all about transmitted because a PI detector does not receive and compare frequency information. Meaningless fluff, an industry insider joke. Get your 96 frequency detector right here.... Garrett Infinium ad - 96 frequencies! Carl Moreland weighed in with his frustration on another thread. White's even gave room over in the V3i manual, probably with Carl's input, to comment on the situation. From the White's V3i Owner's Manual, page 6: "There is much confusion - some of it deliberate - over how many frequencies a detector actually uses, and whether multiple frequencies are truly better than a single frequency. What defines a multi-frequency detector? What do multiple frequencies really do for depth and discrimination? A multi-frequency detector is defined as one that simultaneously—or, in automated sequence— transmits, receives, and processes more than one frequency. Some detectors have the ability to operate at one of several selectable frequencies, but they still are single frequency detectors because during operation they can only transmit and process a single frequency. The same is true of detectors that have a control to slightly vary their operating frequency to minimize interference; even though they have the ability to operate at many (slightly) different frequencies, they are fundamentally single frequency designs. Currently, all multi-frequency hobby detectors run their multiple frequencies simultaneously as opposed to sequentially; they are all characterized by having multiple processing channels in the receive circuitry. Therefore, a 2-frequency detector will have two processing channels. Spectra V3i has three independent processing channels; it is a true 3-frequency detector. This all sounds easy, so where is the confusion? It turns out that (currently) all multi-frequency detectors create a transmit signal that is composed of digital waveforms which are designed to produce peak energies at the desired frequencies. As a side-effect, these digital waveforms also produce undesired harmonic frequencies. Lots and lots of harmonic frequencies, 10’s or even 100’s of them. These harmonics have no useful energy and are not part of the signal processing. So while we can claim to transmit many, many frequencies, we cannot claim to process or use them. Therefore, we could easily claim the Spectra V3i transmits 17 frequencies, or 28, or 39, or 55—we could get plain silly with this. And such a claim would be true, technically speaking, but since all those extra frequencies are not actually used, it would be misleading to make such a claim. White’s chooses, instead, to claim the number of frequencies we are actually using and processing. It may not sound as impressive as a 55-frequency detector, but it’s honest and accurate. Pulse Induction (PI) detectors also utilize a digital (pulse) transmit waveform, so they transmit a tremendous number of harmonic frequencies as well. So is it fair to include pulse induction as a multifrequency technique? Not really, because PI detectors process in the time domain, not the frequency domain. So even though they use broad-band signals, they are not frequency-based detectors at all. Calling them “multi-frequency” is simply another attempt to confuse the consumer. Once we get beyond the marketing hype, the real question is: What does multi-frequency do for depth and discrimination? The truth is, any time a detector is simultaneously transmitting more than one frequency, the transmit energy must be divided amongst the frequencies. Therefore, a single frequency detector can usually squeeze out slightly more depth than a multi-frequency design at that certain frequency. But this is an advantage only at one frequency, which tends to favor only a narrow range of targets." These are old debates going back to Minelab BBS and it’s 17 transmitted frequency claim. I reference it all in my discussion at Selectable Frequency And Multiple Frequency Anyway, interesting subject for armchair engineers and armchair attorneys. Hopefully you all get it sorted out while I am out metal detecting!

Everyone who got the December 2018 issue of Treasure Magazine has a collector edition since it is apparently the last one. The magazine has been published in various forms for over 50 years. Unfortunately the company has closed its doors and both the website and Facebook page are gone. Sad to see another part of detecting history fade away.

Nothing has gone missing, but there are so many threads that discuss Multi-IQ that I have no idea which one you are referring to.

All current Teknetics models have been added. I am now going to start listing the most popular discontinued models from various manufacturers that are still in use.

All the current Teknetics metal detector models have now been added to the Metal Detector Database with User Reviews. If you have owned any of these Teknetics models please help others by leaving a review. Discontinued Teknetics models will be added in the future. For an explanation of the Metal Detector Database with User Reviews visit this link Teknetics T2 Classic metal detector

Four forum members (that I know of) have all found a gold coin in the last year! That seems kind of amazing to me, and shows that many awesome finds remain to be made out there after decades of metal detecting. Dec 2017 Cal_Cobra Bucket Lister!! March 2018 Cabin Fever First Gold Coin! July 2018 The Seeker A Once In A Lifetime Gold Find Dec 2018 strick Gold Coin Story You guys are amazing - is there anyone I missed?

Congratulations strick, an amazing bucket list find for most folks! And in superb condition at that. I guess there might be something to be said for taking a break.

Awesome, love the pics with the kids - thanks for posting!

Happy Christmas and Merry New Year to all!

Hello Clive, I as usual was using unconventional settings that reflect my priorities for the trip, and not what a person with unlimited time might use. I was cherry picking to a certain degree. I wrote up a long article about the settings I was using and the rationale for the settings that I submitted to Minelab for publication on Treasure Talk.. I don't want to step on the articles toes, so to speak, so I am emailing Minelab right now to see if it will publish soon. If not I may go ahead and list the settings, but then people will probably say I am nuts, and I won't be able to explain why I did what I did because that is what the article is all about! Anyway, I will get back to you on this thread soon one way or the other about all that. Thanks for asking. I thoroughly enjoyed every moment in your great country!

People were having issues getting the updates to load, and so this is very likely an update to the updater, not the firmware itself. The latest firmware as Jackpine notes is still 1.7.5

Short answer - no. https://www.detectorprospector.com/forums/topic/1599-gb-numbers-mineralization/

"Some stories are worthy of being told more than once. There are countless stories about lost or buried treasure in Nevada history. Most of these are legends that might or might not have any basis in fact. The following story, however, is one of the rare cases where a real treasure was found, when there was no previous knowledge it even existed." Full Story Here

Welcome to the forum and thanks in advance for participating!

Nope, good reminder for people as honestly I thought they would all be gone by now.

It is a deal for sure, going on since September. I kind of assume they are clearing existing stock, since the whole Jimmy Sierra thing is long since dead and over. Presumably the stock will run out at some point. White’s Sierra Gold Trac (SGT) Data & User Reviews

There is some misunderstanding about frequency. The old rule was lower frequencies are more sensitive to high conductors like silver, and higher frequencies more sensitive to low conductors like gold. The reality is more complicated. Air tests reveal that higher frequencies are just more sensitive, period. In particular, the higher the sensitivity, the hotter a detector is on smaller targets. The catch is higher frequencies light up and see ground mineralization that a lower frequency will ignore entirely. The way I look at it is boosting frequency increases sensitivity across the board. However, in areas with mineralization, a high frequency can generate so much ground response that depth starts to suffer. The machines get chatty or outright noisy, and sensitivity may have to be reduced to compensate. A 71 kHz Fisher Gold Bug 2 air tests like crazy on all targets. Yet in bad ground the machine lacks any real depth and if not ground balanced it is horrible. A very high frequency detector with a preset unadjustable ground balance would be a very bad idea. The lower frequencies do very well on high conductors while also inherently ignoring milder ground mineralization. This in turn means the preset ground balance covers a wider range of conditions well, as compared to a high frequency machine, which has more need to be spot on. This double whammy, lower frequency being good for most types of coins, while also working well and quietly over a wider range of ground types, means nearly any detector with a preset ground balance is going to be running under 10 kHz in the single digits. There are many in the 6 kHz to 8 kHz range, with 6.59 kHz and 7.8 kHz being particular common. The Ace 200 (and Ace 250) is 6.5 kHz, Ace 300 is 8 kHz, and Ace 400 rather hot at 10 kHz.

Lots of people had it done by the factory but few seem to have tackled it on their own. I was fine with the Vaquero as shipped.

There was nothing to resolve. The Dual Field is a hotter coil. Hotter in small gold but that also means more reactive to ground. Turns out the Dual Field was a little too hot for the worst Australia ground, so they went regular mono for the Oz machines. I never had issues with the dual field coils and most people don’t. I loved the little 7.5” dual field. Even in Australia there is plenty of ground you can run the dual field on with no problem. I would not opt for a mono on ground capable of handling the dual field. Everything in detector land is a trade, and while the mono is less reactive to ground it is also less sensitive to small gold.

Absolutely! I sure am not asserting an Ace is as good as a high end machine per se. The thing is the vast majority of people are going to be casual detectorists, and much of the country has far lower mineralization than in the mountain areas. These detectors have a preset ground balance that serves just fine for normal coin detecting. Nugget detecting? I would not bother, though I know of a nugget or two found with an Ace. Not small ones either - they can’t detect the tiny ones.
