Got my Equinox set up on the bench for some coin dTID testing so I grabbed three pieces of (dug) scrap copper wire, each about 3 inches or so in length but in various orientations (~2.0 mm dia. w/hook half loop on one end, ~2.2 mm dia. straight, ~3.2 mm dia. L-shape). The dTID readings on the Eqx were a bit broad but approximately 14-15, 15-16, and 18-20 respectively in Park 1, recovery speed = 4, gain = 17, 11" coil. Targets were swiped about 2.5-3.5 inch above the center of the coil. (For reference, our USA 5 cent hits 12-13 and our modern zinc cents around 21, if uncorroded/undamaged.) So maybe those numbers are more in line with what you expect? The lengths of copper wire I find can be all over the place, from half inch to a couple feet. Not surprisingly the in-field dTID's vary with length and shape, too.

Garrett 24k Wireless Bluetooth Audio
GB_Amateur replied to GotAU?'s topic in Garrett Metal Detectors
I assume you are referring to this. (...aptX LL/FS 40 ms...) -
Seemingly lost in all this is the fact that this detector was released 3 1/2 years ago (Sept-Oct 2018, right?) by White's, and (AFAIK) it's the same detector now that Garrett is selling it. I realize there has been occasional praise (Steve H. for example) in that time period, but for the most part it seems like a secret. Apparently White's demise (although that was well over a year after its release) and the detector's disappearance from the market for ~2 years explains it some. Throw in the fact that it's a specialty detector. An apples to apples comparison is the ML Gold Monster 1000. Was that so calmly released and received? Still, with all the hubub we're hearing now for the XP Deus II (and don't forget the pre-release frenzy of the ML Equinox), I'm surprised it's taken so long for this to get exposed. I blame you, Simon.

It's not that difficult to answer this kind of question before strarting a false rumor. Their website appears to be up-to-date. I count six detectors in the $299-$849 price range still in their lineup. There are a couple cheaper children's detectors and the considerably more expensive computer imaging models and Ground Penentrating Radar (GPR) hybrids also shown there: https://www.noktadetectors.com/metal-detectors/

I find quite a bit of copper wire -- single stranded (but not coiled) used in constuction. I think the gauge is in the 12-16 range. They typically hit in the USA zinc penny and aluminum screw cap range. IMO, an iron alloy nail oriented with its axis parallel the coil's axis (think vertical when in the ground) can give an interesting positive response. Certainly the nail head contributes, but even nails without heads seem to show similar results. My hypothesis is that what is effectively happening is similar to a stack of small discs which add constructively. Do you have a different hypothesis for that apparent phenomenon (or am I just imagining this genearlization)? Possibly I'm assigning a conductive explanation to a ferromagnetic property....

Nice looking design, and it's real (sterling?) silver. The ones that disappoint me the most are the plateds, whether gold or silver. They can come out of the ground looking like the real thing.... %-age wise I WAG something like 75%-80% of my jewelry finds are junk, and it definitely could be higher. But I dig coin zone tones and the junk metal base is often copper, which explains my results. Glad you got out for one nice afternoon. I don't see many of those in the next 10 days.... But then all eyes will be on your state and its famous varmint.

Excellent post, PimentoUK. I will make one small correction -- our USA 5 cent 'nickels' are 75% Cu. I think that drives home your point even more. As a sidelight, during WWII they changed the comp to 56% Cu, 35% Ag, 9% Mn (= manganese). It's no coincidence that these Warnicks, when not adversely affected by leaching, give the same (or very close) dTID (at least on my ML Equinox) as the standard composition. There was an intense(?) study done to match both the conductivity and density because vending machines that existed at the time were sensitive to one or the other, to prevent slugs from being accepted. Manganese is one of the worst metallic elements for conductivity and when leached from those coins, results in higher dTID's. (This last point is my speculation as there is evidence for such, but not rigorously proven to my knowledge.) Excellent! Similar to data I've posted on gold-copper and gold-silver alloys which I found here and was posted in a couple places, including here. I'm surprised you were able to get so many different alloys to create this plot. Did you mix them yourself? What I've never seen is a similar plot for copper-silver alloys. You wouldn't happen to have that one?

Some of us complain that detector manufacturers don't pay attention to us and that they should hang out here, reading our suggestions to improve their products. Do you think threads like this (including the other one posted within the last couple days ago about the new detector being decals, on the First Texas 'fanboys' subforum, btw) encourage them to come here and listen? Corrolary of the Golden Rule: Put yourself in their shoes.

George Wyant ("King George") and Tim Saylor ("The Ringmaster") are the guys you are remembering. Here's the Wikipedia entry for the show that also tells some things about these two. They definitely had a connection with Garrett and apparently still do. They represent that company at metal detecting shows around the country. (They also used AT/Golds on the show. I think it was cancelled before the AT/Max was released.) Gerry McMullen knows them both and has had good things to say about them (posted here a while back). I think they now live near Gerry (if 'near' means, oh, within a few hundred miles anyway). I vaguely recall an episode where they did some detecting for native gold up that way -- Idaho or Montana. But as you remember a lot of the episodes were done at historic sites (with permission, of course) such as the Hatfield-McCoy 'battlefields' in Appalachia.

That explains a lot. But in the limited (fresh-) water detecting I've done it seemed like the 95% copper pennies took it hard, hanging out in the muck. (Unfortunately I didn't find any 90% silver coins to be able to compare.) Your 3rd dime (another Merc) didn't look nearly as bad as the other two.

Which Frequency Is Running In Each Mode?
GB_Amateur replied to vive equinox's topic in Minelab Equinox Forum
Presumably you're referring to Carl Moreland. I only bring up that obvious point because I confused the issue by giving the name of the inventor and company founder as 'Carl Fisher' when his actual first name is/was Gerhard. Gerhard probably knows the answer, too, but I don't think he's a member of this forum anymore. -
Which Frequency Is Running In Each Mode?
GB_Amateur replied to vive equinox's topic in Minelab Equinox Forum
Thanks for another one of your classic, excellent long, detailed explanatory posts, Steve! But I'm left with one confusing thing. The Fisher Gemini 2-box T/R detector (~90 year old design by the original and founder, Gerhard Fisher himself, but still being sold today with a bit of modernization ?) uses 82 kHz operating frequency. How does that squeeze its way into all of this? -
If you're wanting a reliable 'yes' answer, at least in the IB/VLF arena, I predict you'll be hearing crickets. I hope they surprise us, but I hope a lot (regarding all MD manufacturers). Two brand new multifrequency detectors (from XP and Nokta Makro) are being released early in 2022. And there are many high quality detectors already on the market. Usually the waiting game only results in just that -- waiting.

From the looks of two of those dimes, the water+soil combo is no friend to 90% silver. And obviously worse on the 95% copper as that middle Wheatie is worse than burnt toast. I'll stick with the dry land, although the ease of hunting that means I have more competition. I'm not a gold jewelry detectorist but due to gold's chemical inertness (at least until it's mixed with too much copper), not to mention its high bullion value, I realize that's what you water hunters (salt and apparently fresh) are really after, anyway. Not intending to demean your efforts, Dan. Even that toasted silver retains its bullion value, but I get more excited seeing your numismatic valued finds and except in the worst soils you've apparently got a better chance for those in the dry, as I'm sure you know.

Henry 3 Gold Penny Found
GB_Amateur replied to Steve Herschbach's topic in Metal Detecting For Coins & Relics
Three days to go and already 230k GBP has been bid. There's a humble account by the finder in the auction's description entry (included in the above link), although not with details we'd like to see (e.g. no mention of what detector he was using). -
Welcome, Ogliuga! I don't know if "green with envy" translates properly to Italian, but that's what many on this forum are now, reading that you already have a Deus 2. Keep us informed as to how it performs for you.

So Denver minted rarities make it out there, too. ? Eastern USA, being older, has some good stuff as well, but because the branch mints typically made fewer coins per year and most of those were released in the West, I think you have an advantage for those who care about date+mm. Older low denomination type coins are more prevalent in the East. First time I've heard that, but it's a great way of putting it. People ask me why I spend hours collecting less than $1/hr (and that doesn't include expenses). I'm going to use your answer from now on although I still don't expect them to understand. Just as well; the competition is tough enough already. I'd rather find a coin worth $100 than be handed a $1000 lottery ticket. Again, most people wouldn't understand, but I bet you (and quite a few others here) do.

If You Are Considering Getting A Deus 2...

Umm, are you forgetting the 2022 metal detecting mantra?? -
If You Are Considering Getting A Deus 2...
GB_Amateur replied to Rick N. MI's topic in Metal Detector Advice & Comparisons
I was thinking "you must be new here" but now I see you have one of the earliest "Joined" dates I've ever seen. Here is the Nokta/Makro subforum where there has been considerable discussion on the Legend. (Scroll down to see various threads). The forum you (and now I) posted on has some comparison info, too. The XP Deus II release has stolen a lot of thunder from the N/M Legend's imminent(?) release. But the Legend also has some detectorists excited. Note the Deus II costs twice what the Legend does so expecting or even hoping that the Legend will be as good may be asking too much. We will know more about both in a couple months -- just in time for the arrival of warm weather detecting season in much of the USA, Europe, and the British Isles. -
Yep, that's the 1894-S. Mint records show 24 were minted and it's been speculated that they were only made to balance the books for the year. One has been found in circulated condition and it's thought be be the one you mention being spent by the mint director's daughter. (PCGS won't let me look it up because my browser is outdated.) But as you point out, the known count is about half of what were minted, so there's hope for us detectorists yet. I'm not sure I want to find that one -- my heart would likely cease beating permanently and I would only have a few seconds to enjoy it, but as they say: "what a way to go!") Interestingly(?) there was an episode of History Channel's Pawn Stars where someone actually got on the show (!!) claiming to have an 1894-S Barber dime. The date was so damaged it was unreadable. Talk about 'wishful thinking'.... Idiots (or cons) like that should never receive publicity. I quit watching that show a couple years ago -- too many a__holes behind the counter. But before that, every once in a while they had some really rare coins show up. My memory recalls 1866-S $20 gold piece in high grade uncirculated (might be mis-remembering the date; might have been a 61-S but not the Paquet version) -- I think Rick bought it for near $40k. Another episode had an extremely rare 1922 (proof) High Relief Peace Dollar. If I recall Rick offered around $90k for it; can't remember if the buyer let it go for that. You Western USA coin detectorists have it made! (OK, you still likely have to put in thousands of hours to find a rarity, and then need to get lucky on top of it, but there are certainly some rare ones out there and many have been shown here.) I've never lost my breath or even gotten my heart racing from a find, but I'd make an exception for something like those two gold coins you mention. Hell, I'll get excited if I can just find a 1939-D Jeffie. (Now someone here is going to say s/he's found multiples of that date+MM. Go ahead, rub it in. ?)

The Next Legend Update Explaining The Delays In Release

More Finds With Eq800 In El Paso Mountains
GB_Amateur replied to aerospace guy's topic in Detector Prospector Forum
Not sure about the entire state of California. And don't forget New Mexico. Here is a list of all her books plus some maps. I suspect she has oodles of journal artices as well. Prolific writer and someone for whom West and SW USA native gold detectorists should be thankful. -
Welcome Bigelow! You definitely came to the right place for more reasons than one. Steve's Guides (click here) have lots of general info (including prospecting) and for the Equinox specifically:
