Two trimes now -- that's quite a feat. Luck plays a part but the fact that you dig these where ring tabs show up on the dTID scale -- many others would miss that, including me when I'm not realizing those mid-18th Century coins might be present. And, yes, they sure are tiny! How deep was yours? 1851 is first year of issue (which ironically tends to lower its value relative to other years). My memory indicates someone else found one of these recently (abenson?). That's the only year that had one produced with a mintmark (-O). It would be to the right of the roman numeral III. I don't see one but that area is pretty dark from scaling. This one was in great shape when dropped. It might clean up but that's always an iffy topic. Is the lead 'button' a hem weight? Too bad for the condition of that token. 3 1/2 cents?? That seems very unusual which could make it valuable (maybe even in the three digits) if in better shape. Still, should be fun researching it. Does the other side show anything? Those levers look like they could be from faucet valves on a bathroom sink. If so they likely should have teeth in their openings. (Or are they too small for that use? Can't tell from the photo -- needs some scale...) Excellent group of finds for a day's detect. And I bet there's more. (nodding)

Can't those who have a detector with a clock just ignore the clock? (phrunt already answered this so mine is a rhetorical question.) The reciprocal situation isn't possible. A time accumulator would be nice instead or in addition. I recall many years ago Steve H. mentioning buying those cheapo stick-on clocks at a 'dollar' store or discount department store and attaching them, but that was back when most control units were rather large, and they might not even sell those clocks anymore. For those married to their cellphones (if you're off the grid when detecting I assume you don't carry one of those, either...), no need for even a wristwatch anymore. I'd rather have a clock on my detector (I don't) than carry a cellphone when dectecting (I don't). There's no danger the internal clock will interfere with the detector's performance. Can you say that about a cellphone? (warning: more rhetoric ?)

It's not just the notching but also the transmit frequencies (well, more specifically receive frequencies that are processed) that are selected for each mode (by the engineers -- we users don't get to fiddle with those). Typically high conductor ==> low frequency is best, and vice versa. For sure you should still find metals over the entire spectrum (when not notched out) but likely other modes will give better performance for the USA nickels (and correspondingly worse performance for high conducting primarily silver and copper alloys). At least that's the way it works for single frequency detectors. Multi-frequency is quite likely more complicated, and being able to combine a low frequency with a high frequency could (conceivably in my simple mind) allow very good performance for a range of conductivities. P.S. I'm probably overstepping my knowledge base here. Maybe the mode chosen for the 'Super Slayer' isn't one that's heavily weighted to low frequencies. (I don't speak Deus which makes my wandering into this unknown neighborhood even worse.) I was speaking in generalities and you're referring to not only specific notching (to concentrate on certain targets) but also a specific mode whose primary design (by the engineers at XP) may or not be optimized for the highest conductors, at the expense of lower ones.

Just in case you haven't tried it (likely you have), did you try the two switches on the one headphone in all four positions? One of those switches will severely mute the sound on my Pro Golds when using it with the WM08 of the Equinox. One PitA of adapters and even with audio connectors in general is that there appears not to be tight standard on the plug length (and/or effective socket lentgh). This seems to be particularly bad with the 1/4" plug-socket mating. I use a 3.5 mm male to 1/4" female to mate the WM08 to my Pro Golds (which aren't the CTX version, btw) and I have to use four plastic washers slid onto the 1/4" male plug to get proper contact/mating. It works but IMO these things should never happen with good standards and manufacturer tolerances.

Looks like you've found a remedy product that's better than snake oil! Depending upon how it got there (more on that in a bit), it might provide some evidence of the age of the site. In my area parks are often built on top of or adjacent to old homesteads. When those buildings are razed, sometimes the contents get scattered and left for... us detectorists. So although the park may or may not be from the beginning of the 20th Century or earlier, what preceded it may well be. I'd say you've got a good hunting spot that either others haven't searched hard (because of the trash) or just ignored because that area didn't seem to be much used by park visitors. I've experienced both. I assume that 'silver slayer' program is really for any high conductor, and maybe optimized for the sizes of (high Ag content) silver coins and jewelry. Thus clad and 95% copper pennies are likely finds as well as silver plated copper (junk jewelry and inexpensive, utilitarian flatware popular before stainless steel replacements took over). USA 5 cent coins ('nickels'), though, not so much.

Did you watch this video linked by phrunt last week? IMO that has the most complete explanation of Manticore settings. Since I (like you) only listen to the full TID spectrum on the ML Equinox (custom 5 tone mode in my case) I don't pay much attention when Lawrie and others describe how to set up discrimination on the Manticore. I also don't speak FBS. ? But maybe that video will give you a better idea of how the Manticore works (or not). I've yet to see a clear explantion of where ferrous is on the discrimination scale. There's the Dankowski claim that the detector reads TID's in the range -99 to +99 (or at least I think that's what others have reported him saying) and there is a red underline of dTID for some targets in videos (including the above one) which indicates a ferrous target, but I still don't know if that means you should mentally put a negative sign in front of the two digit TID.

At this point it seems (they have been vague so far, IMO) the built in wireless is proprietary. They've also said any changes from now until release will be in software; hardware is done. Maybe we'll be surprised and find out differently regarding the wireless system(s). There are still options: obviously included speaker and a 3.5 mm socket for attaching 'wired' headphones. But a system like the Garrett Z-Lynk transmitter+receiver will allow user chosen headphones (although that particular system will require adapters since it's 1/4" plug&socket). Quest may have a similar system that uses all 3.5 mm connectors -- don't know.

Welcome, glacialgold, from a fellow Hoosier detectorist! It can be tough sledding around here for both gold and silver, but just like everywhere if you can find the unkown (to others) locations there's still some good finds to be had. Sounds like you've found a few places which haven't been cleaned out.

Great historic finds, Plat! I think you guys are on the right track with that whatzit. This came to mind when I saw the pics.

I use Bose Soundsport earbuds (a version/model no longer made) with the WM08 which work fine. Is your plug a straight or right angle? Sometimes the latter doesn't have a long enough straight section which keeps them from fully inserting. I'm modifying my Sunray Pro Gold headphones right now, replacing the 1/4" angled plug with a 3.5 mm angled plug. Turns out the plugs I bought a while back aren't going to work if inserted straight into the ML Equinox 800 (i.e. without any wireless transmission), for the reason just mentioned. I'm anticipating that the upcoming ML Manticore won't be as friendly as the 800 -- i.e. if you don't like their included ML-105 headphones (and/or the latency of their new proprietary[?] wireless), you're either going to need to use a 3rd part transmit/receive system (e.g. Garrett Z-Lynk) or just go the old-fashioned route and plug headphones directly into the control unit. ML may decide to provide (for a fee) proprietary earbuds as well, but if the system actually is proprietary (still not clear, IMO) then the options are going to be limited. I've noticed there doesn't seem to be a standard for the lengths of the plug sections. As a result, some fit so loosely that they don't seat well and cause cutouts. That's the case when I plug a 3.5 mm male to 1/4" female into the WM08. In that case the 1/4" side has the problem, not the 3.5 mm side. But maybe what you are experiencing is similar. (I use some nylon 1/4" washers as shims to take up the slack -- that works.) We shouldn't have to jump through so many hoops to get compatibility for what should be standard mating....

(I welcomed you and asked a couple questions in your Meet&Greet post. You've started answering my questions here.) Welcome (again)! Here are some warnings about advice for someone wanting to enter the hobby (aka 'newbie'): 1) If you really have a budget, and you seem to, then beware of people suggesting things that don't fit your budget. That seems to happen here all the time. 2) Although used detectors can be a bargain, they can also have problems. Particularly for someone new, if the detector isn't working the way it was expected then one's mind will be filled with doubt as to whether or not you got someone's lemon. Go new now until you get confidence in your abilities. 3) There are several more/less required accessories, especially a handheld pinpointer, a digging tool, and a pouch. The latter two can really be found on the cheap in a big box hardware/lumber outlet -- e.g. a garden trowel and a nail apron. In particular, though, the digging tools sold be detector outlets tend to be sturdier. Another accessory that isn't typically required (if the detector has an internal speaker) but can be quite useful is a set of headphones. Regarding this third point, some outlets provide packages that include a lot (or all) of the above mentioned accessories. SeriousDetecting is a good one. You can search for various models (e.g. Nokta Simplex, Garrett Apex, Minelab Vanquish) and see what kind of package you can get that fits your budget. You can still shop around with other dealers but the site I linked will at least give you an idea of some available, decent pricing. Example: Simplex with wireless headphones and handheld pinpointer. ($375 before sales tax) Get one of the best hand diggers. ($40 before tax -- not sure about shipping) The pouch I use. ($31 before tax) And maybe a few bucks leftover to take your wife out for fast food. ?

Welcome, Ruben! Well, yes, the Garrett Apex is a specific detector but Nokta Makro is a detector manufacturer & seller, with several detectors available. Did you mean their Legend model? Simplex model? I'm always curious when a new user has narrowed down a purchase choice already. Local supplier? Friend/acquaintance who has made a recommendation?

That description fits the Kentland Crater in NW Indiana. My parents used to own land over it so I know a bit about it (including some unpublished tidbits. ?) It was discovered by accident only many decades after it was producing limestone (for roads). In the 1960's when a geologist hypothesized the limestone dome was caused by a meteoroid, the quarry owners tried to nix that idea since (apparently) they thought their operation would be shut down -- kinda like what happens when Native American burial sites are discovered. In the late 1970's some geologists from University of Kansas showed up to research its age. My dad contacted them and one even came to dinner at our house. I was able to pick his brain a bit. Their conclusion which was published in 1978 was 250 million years with an uncertainty of (plus or minus) 100 million years, if I remember correctly. The Wikipedia article shows that now there are two competing ages (97 million and 300 million -- but Wikepedia not quoting uncertainties ?). BTW, on a side note (but definitely relevant to detectorists) is that one of the geologists spent his free time in the area roaming through the countryside looking at rock piles made by farmers clearing their fields of plow damaging material. (Those are/were fairly common.) Apparently he had found a few meteorites in those over the years.

I haven't seen this one posted (thanks; I've now watched it twice) -- it's just released on 11 October even though it was recorded over 3 weeks prior to that. Besides picking up a few tidbits I hadn't noticed previously (more on that shortly), Lawrie steps through much of the settings options and explains them. (He's done this on other videos so either I missed some things or he's going into more detail this time.) At ~7:30 he mentions the 10 search modes and then says each has a different combination of analyzed frequencies (repeats that at ~10:10) . That's good to know (kinda like the Deus 2?) and taken literally it's at least twice as many as the Equinox. Unfortunately many of the screenshots are invisible due to reflection of skylight. (Wish they would apply frosted screen protectors -- something available for laptops and smart phones for almost 2 decades?) But one shows the red underline of a iron/steel washer with the dTID in the high 30's. It's still not obvious to me that this is an actual negative 38 dTID or that the conductivity reading is 38 and the ferrous reading (equivalent to first number of two on the FBS detectors) is just indicated with the red bar rather than a number. Of all the videos I've seen I don't recall anyone delving into this. Early on he explains why there are extra ribs on the coil housing. For those water hunters who have been complaining about this, it's necessary for coil stability. Now, if you wish they had enclosed all this in some kind of mono-housing, that seems like a separate (but related) request. Probably some are getting fatigued reading me complimenting this approach of having an engineer who was intimately involved in the design and implementation be a spokesperson at videoed public and private gatherings. But contrast that with other videos (including the recent one done at Myers' in Florida). I like correct answers as well as hearing the reasons things were done the way they were, and Lawrie's videos have both. An open Q&A with him would answer most of the questions many of us here at detectorprospector still have. One final thing about the headphones. I seem to recall someone (possibly even associated with Minelab) saying the GPX6000 headphones will work with the Manticore. Not only do I not recall Lawrie saying this, but you'll notice in this video in the last couple minutes where his words are carefully chosen when he mentions the similarity (I think he says "form factor") of those with these 105 models. I take that to mean they are outwardly (physically) similar but inwardly (electronically) different.

Pretty sure (it's been a month now...) Lawrie said in one of the European Tour videos that Bluetooth is not supported. (Someone asked -- he said 'no'.) If it's low latency but not Bluetooth, does that mean proprietary? What does the GPX6000 have?

Had to Wikipedia 'German silver" which made me realize I know it from another name -- nickel silver. Funny story which I may have told here before. About a dozen years ago in an antique shop I saw some cream and sugar pitchers with that marking. Thinking they contained silver I did some arithmetic in my head and concluded the bullion value was likely more than the asking price ($90 etched permanently in my memory) so I stealthily took them up to the counter and paid without revealing my 'find'. After (proudly) driving home and looking up 'nickel silver' to calculate my 'winnings' I was deflated to learn it contains no silver. Surprisingly to this day is that not only does it have a good white color, like silver, but it even tarnishes to the same color as silver. (I say that, but now I wonder if these are silver plated....) I don't know what the salt water does to it, but maybe your discovery answers that. Is that a '1944' date I see peaking out of the photo?? ?

Yep, all good, Steve. I didn't mean to counter what you said but rather enhance it. And since I've never used an FBS detector I was hoping to get a confirmation, which you gave (thank you for that). Possibly I should have been more careful/explicit in my post -- next time.... That was my first impression when seeing the still shots of the screen. But watching (a lot of) videos with engineer Mark Lawrie's explanations, I decided what looked like a histogram was actually some kind of iron discrimination pattern -- I think he said that in at least one video. Since I don't use any silencing discrimination except for single pitch mode detectors (in my case the Tesoro Vaquero), I eventually just ignored those bars on the lower part of the X-Y screen. Personally I'd much rather have that replaced with a histogram, but don't anticipate that happening on this (Manticore) detector as it's in the very late pre-release stages.

Suppose you have a target that is giving multiple dTID's, but there is a clustering around a particular (conductive) value. E.g. 22,25,26,29,26,25,25,24. That may be difficult for the human brain to decipher, but a plot (even one dimensional) should indicate there is a peak at 25-26 in this example, and especially if more datapoints are integrated in the X-Y plot. I appreciate your explanations, being one (of many) who has never used an FBS detector. But "a picture is worth a thousand words" and "a plot is worth a thousand numbers". OTOH, I think (and there was at least one example in the ML European Tour videos) that ground conditions, target depth, and/or multiple targets (at different depths) don't give the ideal view that some cherry-picked ideal arrangement of one or two targets on top of the ground will show. Inevitably we are going to hear griping that the sizzle was better than the steak. But if we only get chopped sirloin to replace stew beef, I'll be happy. There is the hope that improvements since the Equinox (and since FBS) in signal processing will show improved ID'ing of iron trash, such as with some nails (as you mention). Note I say 'hope' because up to now I haven't seen reliable, clear evidence that such is the case. That hopefully (there's that word again ) will become apparent when I and others get their hands on one.

Ok, maybe nickel plated? White gold plated? Back before the pandemic I got to detect an 1850's homestead. I found something similar (I figured copper but couldn't see a coating -- maybe long gone) and I thought it was possibly a child's toy. But the lady who owned the house said she thought it was an actual wedding band. Makes sense that not everyone then (or now) could afford a solid gold alloy ring but still wanted the 'connection' that comes with such mementos. Kinda the early version of today's tungsten or titanium wedding bands? If it's copper but with a nearly imperceptible break (e.g. where it had been soldered), wouldn't that make it dTID lower than a similar composition ring with an intact conductive path?

Decent finds for a 2 hour hunt, dogo, although not quite up to your standards. ? Are you sure that ring is copper? I would have expected copper to be in the 30's and even brass higher than low 20's. (I'm not much of a jewerly detectorist, though, so keep that in mind.) Don't throw it in the recycle bin until you've checked it out more!

If the property is publicly owned (here in Indiana they are county property), there are no signs prohibiting entry (or detecting), and there are no fences blocking you from entering, I say go for it. Here in my county the entire fairgrouds is fenced in. Even though sometimes the gates are unlocked (for activities) I haven't tried detecting it as the gate is otherwised locked. Clearly they don't want unofficial visitation although in my case asking for permission wouldn't be a bad idea. Here are my thoughts regarding parking areas: (except for the modern electronic keys which don't need to be inserted) where do people keep their car keys? Where do people keep their loose change? You can take it from there.

Multiplying those two numbers is still 1% or 100 times what she said. Now, maybe 1% (or equivalently 0.01) is what she meant and got the two things mixed up (in ML's favor)....

280 million years old and not discovered until the 1990's; disagreement between researchers regarding its origin; real scientific research in action! Good stuff.
