I am tired of not being able to detect Diamond Studs.........HELP!

[signal]

So let me get to the point. Diamond studs, are VERY DIFFICULT to detect. Do not assume your equipment will detect them.

I just took a High quality diamond stud earring and tried to detect it with my CTX-3030, in multiple modes, perfectly ground balanced, and it can’t. My AT Pro Can’t. My Excal can’t. My Garret Carrot, you have to literally put it on highest sensitivity and TOUCH it to the stud, you can’t even be 1mm away, you have to physically touch it for it to go off.

Obviously to slay the gold (in this case it was white gold) diamond stud issue, I need a GOLD machine. I don’t want to spend more than I need, as you can spend ALOT on a gold machine, but I want quality and something that is going to put this to bed! Help me!

I am considering:

Equinox 800 - I hear it has two gold modes which are very impressive, and it has some things much better than the CTX3030, which I already own, and is about 3x the price.

XP Deus - I have heard good things about this detector too when it comes to gold.

Goldbug/Goldbug2 - I don’t know much about these, but I have seen them recommended.

Garrett AT Gold - I have come to love the AT Pro, its solid. I have hard the AT Gold has higher frequency to deal with gold and could possibly detect diamond stud earrings.


And as a pinpointer:
Whites TRX - I use only Garrett Carrots, but I have heard the TRX does better on small gold.

Please give me your advice. I am really only interested in advice from those who have used these machines on SMALL gold. You can’t assume. I would never have thought that buying so many thousands of dollars of top of the line machines (Excal, CTX3030, AT Pro) that I would not be able to detect a diamond stud, but it just can’t. I have many coils too, on the CTX and the AT Pro I have sharpshooter small coils and result is still the same, I can air test, turn sensitivity WAY up, go all metal, it doesn’t matter, the high quality white gold diamond stud is completely transparent to these detectors.

What is your experience?

I have found numerous with the Deus. The only place I look for them is a salt water beach. I use an extremely high frequency. Mine loves small gold. I'm not sure about the other machines. I'm sure someone will chip in. I noticed small foil on the salt beaches is distinguishable from the gold, FYI.

My EQX 800 is very sensitive in detecting small objects like you mention...much more so than either my CTX3030 or Excal II.

The Simplex barks at them, no worries

I am glad to hear you are going after those... so when and if we detect together I will go in front of you.

And...

IF its smaller than a dime... you can have it. :P

I have found lots of studs with my Nokta Impact and Deus. Just use a detector that can run at 19Khz or higher

Is higher better? Many detectors can do say 20khz or 40khz some even 75khz. For a diamond stud earring I am wondering if all of those are equally good.

CTX and AT Pro have no trouble detecting foil, thats for sure, even the tiniest pieces......and yes readings wise I noticed they come up similar to gold, but with small gold the low frequencies just don’t cut it.

On my machine I can tell the small foil. The tiny gold sings out at 74khz. That's only available on a Deus and with the HF coil.

@smokeythecat thanks for the info. So say you are swinging the Deus with HF coil @ 74khz. Are you still able to use discrimination? Or does that setup pickup a lot of trash? Do you have to turn the sensitivity way up (because its a small stud) and thus pick up lots of trash and deep targets? Or can you say turn sensitivity down to just get surface targets that are gold?

It says the Hf coil only goes to 59khz, how do you get to 74khz?

Edit: never mind I see there is the HF Eliptical Coil which goes to 81khz.

My EQX 800 is very sensitive in detecting small objects like you mention...much more so than either my CTX3030 or Excal II.

I've found more stud earrings and small linked chains with my Equinox 600 than any other discriminating machine I've used. If you're in an area where the Gold modes are stable, those work the best. In more unstable areas, I find Field 2 the next best, with Park 2 a distant 4th.

I was hoping an Equinox 800 would do well for diamond stud’s but this post here:
https://theringfinders.com/blog/tag/...amond-earring/

Has me concerned. he says the 800 couldn’t do it. But then I have another post where they say it could do it:
https://www.detectorprospector.com/f...-you-cant-yet/

For sure the XP Deus can do it with the HF Coil, but its a single frequency machine so it won’t be replacing my CTX3030, but could totally replace the AT Pro and add in additional small gold capability, but at a hefty price (machine + HF coil is $$$$).

Can anyone with a Equinox 800 try a diamond stud and report back how well it can detect it? Perhaps using a smaller coil is needed. Air test is good but better even in normal soil.

[smokeythecat]

Most multi frequency machines run TWO FREQUENCIES and harmonics to make up the others. Recovery time I believe is much more desirable than splitting power between two frequencies and the harmonics to go with them. Check out the posts by vferrari here, who i dig with and understands the ifs ands or buts on this type of discussion much better than I could. The discriminator is excellent, and depending on how many tones you use, you can use the VDI and the tonal capabilities to make a quick dig/non dig decision. With the elliptical loop, you get excellent target location, unlike what you can get with a larger coil.

I find stud earrings in water ...fresh and salt - I wear a mask and many times i can see multiple scoop marks around them which tells me
they are falling thru scoop holes - i will drop down and lightly fan and they are right there
- I hunt all metal and probably swing slower than most
