Gold questions, why so elusive
- Thread starter campnagle
- Start date
Wondered all that myself I did..gold doesnt tarnish, so thats why the electronics mfgs use it on the contact points I believe. When I was new, I also thought gold would scream, imagine my dismay upon finding out it could be just about anywhere from foil on up... Jim TN is feverously hunting for a gold coin, and he ought to be along shortly, from his post yesterday, if he's digging those .22 cartidges, he's hunting in foil for one. It would be cool to take the detector down to some friendly coin or pawn shop and sweep a few gold coins just to hear the noise, of course, air test may not give a real world in the dirt result, but close enough I would think. One other interesting thing about a similar heavy metal.., little lead splitshots sound like gold, but big lead sinkers sound like silver, so whats a feller to do? Dig it all?
I think as long as a guy is out hunting, in those spots you are, where theres old silver, you have a very GOOD chance for a gold coin...me, I have a very good chance for a gold coin in a bezel lost in a totlot or at the beach, or at a soccer field...I dont think its a matter of how many targets a guy can get, but it sure does increase the odds on the Luck factor if a fellow is out and hunting...I KNOW I wont find a gold coin sitting around in the house...! nice rings there Camp!

Relative to gold coins, Tom D did a thing some time ago with the F 75 on gold coins and they id as follows.
$1.00===26
$21/2===41
$5.00===52
$10.00===61
$20.00===69
As mud and others will attest, gold items do come in the foil range all the way up to a penny. I have never found a gold coin, but have many small gold rings, hearts, charms and so on, over the years and I don't recall any of them ever screaming. A big class ring will, of course, thump pretty good. Not a digger of it all or purposely target gold jewelry, most of my ring finds come in the nickel range and a few in the penny range. Tones and id readings that are a little different I usually dig, particularly on this woods site, as so many strange things seem to show up with those funky readings. Anyway, as a turf gold hunter, Mike Hillis is the man on the F forums and maybe he will chime in. Merry Christmas everyone. HH jim tn

gold is a low conductor coins are a high conductor
since gold rings are diffrent like 10k 14k 18k ect
the have other things in them like nickle/copper/ect to make the diffrent karets
they will fall all over the spectrum
i find a lot of my gold rings foil-nickle mostly the thin ladys rings
the big chunky mens rings come in as pulltabs-zink
ive only found 1 ring in the square pulltab range
i love big chunks of foil
gold has a nice repeatable tone ,if its deep it will sound soft
ive found 100s of rings & nuggets over the years
focus on odd numbers with a solid & repeatable signal
hope this helps
good hunting

Hi Campnagle, you are right, gold is an excellant conductor. The problem is that it is extremely rare to find a piece pure enough and large enough to read like a high conductor on our detectors.
Interesting thing about gold jewelry is that there really isn't that much gold in most of it. 10k is only 41.7% gold. 14k is only 58.5% gold. Its not until you get into the 18k and higher values that gold starts to really become the majority of the metal makeup of the item. So the item has to be even bigger to read higher up the conductive scale.
Then factor in the metals that are alloyed with it to make the different colors: White, Rose, Yellow, Bronze, Red and Lime. Then add the coatings that are added to some of those to improve the colors. All that affects the conductive reading, too.
The reason most of the gold we hunt is down below the nickel range is because most of the lost gold jewelry is worn by women, and women wear small gold
One more thing to keep in mind is orientation in the ground. If the ring has a crown like the one in your pictures (which I like very much, by the way
) It very likely will be face down in the dirt because thats the heaviest end and that will also affect the conductivity reading.
Also, think about silver. Silver is a high conductor but the smaller the silver is, the lower down on the conductive scale it reads.
Hi Walt.
Like your gold picture! Did you rescue that from the river?

Exactly right Mike.

The only reason gold finds favor in electronics is it is impervious to oxidation and so will not tarnish or corrode. Silver is a far better conductor but is avoided in electronics for the opposite reason; it readily tarnishes. And identical size piece of pure silver reads much higher on a detector because it is a far better conductor than a piece of 100% pure gold the same size.
Silver is the most conductive metal, and so on a scale of 0 to 100, silver ranks 100, with copper at 97 and gold at 76.

Saw something on TV the other day about how Gold arrived on this Planet during what they call the "Great Bombardment" of meteors or asteroids or somesuch billions of years ago...thats why theres not a whole lot of it, it just showed up one day, and got mixed and scattered all over the place. Still, when you read or think about the Atocha, and how much gold it carried out of SA, big chunks of it must have been laying around for the amount the Aztecs got with no heavy mining equipment or modern devices. Seems it drives Men crazy if you think about it too much. The ones who climbed the Chilkoot Pass in winter are a good example.
