What Can A 3mm 10k White Gold 4 Prong Earring Stud Tell You?

Recommended Posts

You either have the right metal detector for micro jewelry detecting or you don't. 

I hunt gold jewelry on land. It is my desired target. I focus on it to the near exclusion of all else. I hunt for hot spots and when I find them I prep them for efficient recovery of new losses. It is what I like to do. And I find pretty small jewelry. Too small to even take good pictures of with my current camera. So I thought I was doing pretty good. Maybe using the term 'Micro' was splitting hairs. 

I had asked Tom Dankowski what to use for a Micro Jewelry test piece. He replied back that a 10k White Gold 4 or 6 prong stud earring capable of holding, what? a 1/4 or 1/2 caret stone would be a recommended test object. So I went searching for something and finally obtain something at the right price off of ebay; 3mm solid 10k white gold 4 prong stud earring. Silicone backing. So its just the earring stud itself with a topaz stone in it. Pretty tiny. Smaller than I thought it would be when I ordered it. 

Ok. The Gold Bug Pro is a proven prospecting unit, and my G2+ is nothing more than a Gold Bug Pro on a different rod set up. I've seen the pictures of the small gold pickers it can find. So surely it will hit this earring no problem, Rght? 

Well, I put the 5" DD on it, and start bench testing. All metal gets a hit on it out to about 1-1/2" if the prong end of the earring is facing it. Horizontal and Vertical orientation presentations are much less. In Disc, I can get a signal about an 1" away with the prong facing the coil and the other orientations are about 1/2" with mostly non-ferrous responses. That is at maxed out sensitivity. Wow. I thought it would be better than that. 

I have a V3 with a 22kHz single frequency option with a hot gold program on it that will hit it good, too. Right? 

Well I put the 4x6 DD on the V3, load up my hot little gold program and start my test. Hey, I'm getting something, thinking positive...better depth than the gold bug, oh...wait....its picking up my hand. So I transfer the earring stud to a ruler and try again. This time no response. Or at least no usable response. Did some tweaking to the program and still no thing. Wow. Got to try some programming changes and see if I can at least equal the G2. 

Not done yet......what about the Omega 8500. No. Not a chance of every finding one these little earrings with that. Put it up. 

Still not done yet....what about the F75LTD? Lets give it a try. I put the little football concentric on it, maxed it out and frequency shifted for stability and give it a try. WOW. In both JE and Boost mode it did better than the G2. The G2 audio wasn't that strong but the F75 audio was great in all orientations. And I was getting at least an 1" in the vertical and horizontal orientations and about a 1-1/3" with the prongs facing the coil. And it was giving mostly non-ferrous TID. This reminded me again of what a top notch detector the F75 is and will always be. 

Wow. Just Wow. I ended up sitting there thinking about how much time I have wasted at some sites thinking that if 'any' gold was there I would have gotten it. I got over it a day or so later as reality set in and reminded me that hunting really small jewelry has its own little focus and that I need not worry about unless I'm specifically hunting for it. But that if I'm going to hunt for it I need to equipment myself for it. 

And that is the back story to my pre-order of the Makro Gold Kruzer.

Thanks for the micro information.  I too know and understand how good the F75 really is.  I think the Gold Kruzer, coin the phrase, might just be your gold ticket.

      Disclaimer: I've only really been interested in Gold hunting so I'm pretty clueless in using my Nox for jewellery hunting.
      This might be a challenging one, a farmer I knows wife lost her wedding ring in a paddock and didn't realise,  Later the same day they run a plough or some sort of farming gadget over the paddock as they planted it out with grass seed so the ring is likely buried.  They're pretty certain it was lost in this paddock.
      I have been recruited to try find this ring, it's 24k gold with about 20 diamonds on it.  The guy originally gave me the wrong description of the ring, probably his ex-wife's ring he described as he said it had 1 diamond and sapphires 😄
      The paddock is really junk filled, I went and swung my detector over it yesterday morning before skiing and there was iron I assume setting the detector off everywhere in all metal mode.
      I know the VDI numbers are extremely useful for coin hunting but will they help for finding this ring, I really don't want to have to dig everything! Is there a range I should be targeting? I assume Field 1 will be the best mode or maybe Park 1 seeing there is a lot of junk?
      Small gold when prospecting always comes up under 10 on the VDI's, I am guessing a ring will come up higher? 
      Would the Equinox be my best choice or would I be better off using my T2 with Mars Tiger 10x13" or 15" round Stock T2 coil for more ground coverage? I also have a Garrett Euroace with Nel Tornado 12x13" I could use if that would be best.  That's the biggest coils I own.
      I have a GPX 4500 with a 15x12 DD Commander I could use but I don't want to dig lots of junk and I was hoping VDI's would be useful.
      I told them I'd do the hunt for nothing when they tried to pay me as it's a bit of fun for me anyway but they said they can't allow that and they'd give me a few sheep for my freezer for my efforts even if I don't find it but I'm sure if I find it they'll force me to take some sort of payment, I will try refuse as I really don't want it but it will be difficult to not take it when they're forcing it....
      The paddock is about 3 hectares!!!!!  Just over 7 acres so I really have a job ahead of me.  The soil is extremely mild but it seems to have its share of junk.  I assume rusty old nails and tractor bits and mower blades whatever else over the years.
      Any help appreciated.

      are starting to heat up.  I spent a couple hours at the sand bar this morning and managed a couple pieces.  Nothing to brag about as the stones in the ring are CZ's.   The hoop earring is silver plated.  There were 3 other hunters out and their finds were meager as well with only one gold ring being reported at this spot so far.  
      The wire mesh I had welded in the scoop worked a dream.  The earring back in the pic is just one of many tiny bits it captured saving a lot of time. 😉

      The heartbreak

      It really felt good to get out and get started on this years "crop"!  👍

      Hunting tiny gold jewelry in inland sites is just so different from mainstream detecting methods that unless you do it you don't understand the requirements.    
      #1.   EMI stability.   Your detector has to be stone cold stable.  No spurious noise.  None.  The signals you are after are small tight signals and you can’t hear them if your detector is making spurious noises.
      #2.   The detector needs to be able to keep its HOTs at low gain/sensitivity settings because:
      a... You need to be able to focus on the right depth of signals and those tiny signals are not deep.  Most of the time they are just down in the grass roots.   You want to focus only on the top three to four inches of depth.   If you have to run your sensitivity at or near max all you are doing is masking the desired signal response with reports from all the other signals surrounding it and below it.  And in cases where the ground minerals are high, the ground itself will mask the response.  
      b... You need to control the coil foot print.  In this type of hunting you don’t want coil edge surface responses.  You only want to hear what is directly under your coil.   Concentric coils work better at this than DD coils.  DD coils are ok but you get better footprints with concentric and tighter readings on your meter.
      #3.  The higher the operating frequency, the more important the above become.  As the operating frequency goes up, the level of discrimination goes down because the trash targets hit harder and sound better.   In other words, the higher the operating frequency the better the trash sounds and responds.
      #4.  Notch discrimination or some other form of discrimination that will allow you to focus just on the signal range you are hunting.   The only range of signals you are interested in are in the ferrous/non-ferrous boundary range and the foil range up to maybe the nickel reading.   All other signals are distractions.
      I'm editing to add a number #5.   Tiny signal audio boost is a big plus if it can be deployed while keeping original signal response integrity.  
      I'll close with this.....You can take a gold prospecting unit onto a woodchip playground or a sand pit and as long as it can handle the EMI you can hunt with it on normal settings.  But if you are targeting sites  where good quality, tiny jewelry is most likely to be present, you will be working a lot of turf sites where a prospecting detector's normal feature set isn't going to be very helpful.

      This post is mainly directed to UK field detecting where we have had social open air gatherings since Medieval times and on fields littered with coke. I used these settings yesterday and I was hopeful of finding at least one gold necklace / chain but alas none, better luck next time.
      As most of us know it is almost impossible to find a fine gold chain with any metal detector and as it is a long story why but mainly due to Eddy Currents and the metal detector rejecting coke which fits into the same frequency range as thin and fine gold and as here in the UK we find our permission fields littered with coke which mostly emanates from the days of steam engines powering farm equipment and the spreading of night soil as a crop fertilizer and which was collected from house middens and where the ashes from the household coal fires was used to cover the stinking human excrement, these ashes contained large cinders which survive for donkeys years in the soil and give off wonderful signals for metal detectors.
      This information on how to adjust the Tone Breaks to enhance the chances of finding gold chains during field detecting is only applicable to the Minelab Equinox 800 as it has the advanced settings capability.
      To alter the "Tone Breaks" it involves making changes to three "Target Tone Dependencies" which are "Number Of Target Tones", "Target Pitch" & "Target Volume".
      Here is my effort to change the settings to cover the frequency conductive range to give off a signal from thin gold chains in the discrimination zones, at present the default Discrimination zone is -9 to +2 and it is the Zero to +2 segment where gold chains show.
      So first of all select either "Field 1 or 2" your choice.
      Then go to "Target Tone" choose 5 tones.
      Then go to "Tone Breaks" and set the 5 tones as thus T1 = -9 to 0, T2 = 1 to 2, T3 = 3 to 28, T4 = 29 to 38, T5 = 39 to 40.
      Then go back to "Tone Volume" and set tone segments to T1 = 1, T2 = 15, T3 = 25, T4 = 25, T5 = 15.
      Then go to "Tone Pitch" and set the tone segments to T1 = 1, T2 = 15, T3 = 25, T4 = 20, T5 = 16.
      To move from from one tone segment to the next segment use the "Accept / Reject" button ( \//x ). These settings are working for me but then again they may not be every-bodies cup of tea.

      Well today was beach hunt #7 with the Equinox. There wasn’t a lot of detecting room, with the way the tide was today. Also, a lot of people walking and laying out on the beach. It’s getting crowded out there. I was hoping to keep the streak alive today and I didn’t have to wait very long. First good target was the pink stone 14 K Gold ring. I almost didn’t believe it. That made the rest of the hunt less stressful and more enjoyable, as the gold streak would continue. But I didn’t expect to get too much more, but the finds kept coming.  All the time I just kept shaking my head, I can’t believe what Minelab has done!!! 4 gold rings, some silver and a small amount of clad. The broken class ring was found in 2 separate holes about 60 ft apart. The breaking points match up perfectly…they were part of the same ring. The tiny targets were out in full force, as well as the pull tabs too. A small price to pay for the good finds that can come with it. Probably the smallest chain this machine can pick up. Had a hard time locating it once it was out of the hole. I was glad to get out today… a picture-perfect weather day!

      Patch Gold = A patch is a hot spot with the right ingredients (cover, clientele, and activity) to allow re-occurring jewelry losses over time.  Patch Gold is gold jewelry found in this hot spot.   
      This is nice piece of Patch Gold from one of my patches.   18k White gold with a very pretty diamond I found a few weeks back.
