What Detector do i need if i only want to dig up gold but no other metals ?

[merlin01]

Hi,


My recent experiences of Gold Nugget searching with a borrowed detector include a lot of digging out old junk like nails, bits of cans or little iron pieces.

I want to buy my own metal detector.

Is there a metal detector that can be adjusted so it only gives a signal if it's gold and remains silent if it is any other metal ? So i only dig up gold, and don't waste energy and time to dig up other stuff ?

Thanks in advance

The higher the freq the more sensitive a detector is to small gold, the lower the freq the more sensitive a detector is finding highly conductive targets such as coins. Both low and high conductive detectors will still respond to junk targets and hot rocks. There is no detector that will only respond to gold..

. . . . If there is a model that has special capabilities which can be used to reduce the digging out of junk, and increase the chance of it being gold, then that's the model i need.

I'm aware now that there is no detector that only gives a signal for gold. But if there is a detector that is especially ideal for gold nugget searching, then that is what i need.

these 2 are in contradiction, reread what has been posted

for gold - a GPX 7000 (whatever the latest), and you WILL have to dig every single signal
I just passed on a creek, with gold, due to the generations old barbed wire fence running through it

 

[merlin01]

Like i said before, i'm now aware that there is no detector that sorts out trash. The question now is which detector i need.

I'm not interested to dig out super small pieces of gold. At some point it's not worth the effort and time. So maybe a high frequency detector isn't necessary for me then.

GPX 7000 costs 8000 dollars. that's way too much. i only want to spend maximum 1000.

Look into the XP ORX. It may be just the ticket. Good luck and welcome aboard!

Gold is a "Lousy" conductor.

And you grouped it in with the the three best conductors we have.


When you see a gold plated TV tuner, or other electronic plugs, pins, jack, or socket,...
It's there because of it's "Non-Corrosive" properties.
Under the gold plate is copper or silver.
Gold is thrown on only because it will non tarnish.
It stays bright.

That is why gold seekers use machines that are sensitive to,......

"Low Conductive Targets"

The reason I stated what I did is because I backed it up with proof.

Next time read the attachment...

Now, scroll down to the chart titled, "Conductivity, Resistivity of Metals" and look at the top five. Gold is a better conductor than Aluminum. I already know that Gold is a Noble metal and doesn't oxidize.

XP Orx will do it under $1000. You can go with something cheaper like a Garrett Ace 400 or the Minelab Vanquish, but I would get the ORx. You won't grow out of it in 6 months.

If you're only interested in hunting for gold nuggets, I would recommend you get a dry washer or sluice depending on your terrain and water availability. Current detector technology won't isolate gold out of all the other metals. As mentioned, your best bet for detecting small gold is one that operates on a high frequency. The drawback is that high frequency doesn't penetrate the ground as deeply as low frequency. You're still going to dig trash targets that mimic gold readings regardless of which detector you get.

Not sure where you got that but gold is a very good conductor.

Note: In general, metals with high electrical conductivity also have high thermal conductivity


5 Most Conductive Metals

Silver — Consequently, silver in terms of conductivity does not take 2nd place. As a result, silver is by far the most conductive metal on Earth. This is because silver only has one valence electron. In addition, this single electron is free to move around with little resistance. As a result, metals like silver and copper are a few of the metals with this particular characteristic. That is why they are great electric and thermal conductors.

Copper — In conclusion, copper like silver, only has one valence electron which makes this metal very conductive. Therefore, one of the more popular commercial applications is the coating of high-end cookware and kitchen appliances.

Gold — Overall, the list is limited and that is a primary reason (other than its rarity) why this material is so expensive. In addition, the combination of gold’s resistance to corrosion and its conductivity make this metal an extremely valuable resource used in large amount of industrial industries.

Aluminum — Overall, is an excellent metal conductor. This feature, in addition to its low density and high resistance to corrosion, makes this metal perfect for the aeronautic and communication (transmissions) industries.

Zinc/Brass — Although these metals are much less conductive than their four counterparts. These metals are often less expensive and economical replacements when applicable.

So there you have it — The 5 Most Conductive Metals on Earth!

is it being stated that conductivity is synonymous with a material's response to an induced field ?
I believe it is a bit more complex

edit: complex permeability
I suspect mass and shape are as important

What's the advantage of the XP Orx over the other two cheaper options you mention ? It is more expensive, so is there a reason why ? is it better ? Why is it better ?

That GPX 7000 cost around 8000 dollars. Why is it so much more expensive ? What can it do better than the others ? What's different on that detector compared to others ?

I'm just trying to learn about metal detectors as much as i can, i don't want to sound annoying. I'm very thankful that people here take the time to answer.

 

[BillA]

the GPX is designed to maximize the response to gold, yes this is the design criteria

others can describe what can be had for a grand

That GPX 7000 cost around 8000 dollars. Why is it so much more expensive ? What can it do better than the others ? It is advertised (name) in a way that implies that it is specificially to find gold. I know that's never the case. What's different on that detector compared to others ?

7000 is the top of the line gold detector and will find small gold nuggets deeper than other gold detectors. You said you dont want to dig tiny gold nuggets yet the majority of gold nuggets found are small nuggets.

 

[merlin01]

I still want to dig out everything worth more than the time i spend while digging the hole. Not that i wouldn't dig out 0.25 grams.

It's just that every detector probably will be sensitive enough anyway.

You both say that this detector is made for gold nugget search, but before in this thread everyone said it's not possible to "filter" materials as the devices are called metal detectors and not gold detectors. So what's the exact reason that GPX 7000 is so much better ? Saying it's just designed for it isn't satisfying my technical curiosity

 

[BillA]

nothing is filtered with a PI machine (the GPX and others)
my GPX 4000 is the very best detector at finding IRON, also

 

[xr7ator]

My advice is to keep using the one you already have access to and keep at it. Learn how to use it by working with it in the field for at least 100 hours. Have some pieces of gold with you and see how the machine reacts to the items in different conditions. Keep a piece of aluminum,lead and iron with you as well so you can see how they react similarly or not to the piece of gold.
Then you can decide if this hobby is for you or not.
Lastly......GOOD LUCK!!!!!

 

[merlin01]

I don't own a detector at the moment. I guess i'm going with some less expensive Garrett model then, maybe used. Thanks everybody.

7000 is designed to find large and small gold nuggets at deep depths. Owners have used it in hunted out gold field patches that brought them back to life.

Even with discrimination at max detectors are still going to see and respond to junk metal targets..

1) The guy isn't talking about "Pure Gold"
He's talking about gold in the ground.

2) Comparatively silver and copper lead the pack.
And are mined metals.

3) Aluminum is not a mined metal, it is the result of refining Bauxite.

4) Just because you read it on the internet, doesn't make it true.

5) The next thing you're going to claim is that water,.....
is a good conductor of electricity.

 

[smokeythecat]

Something like the GPX series does not discriminate like a VLF detector will...so you will hear and dig every last piece of tin foil, nail, bb and everything else under the sun.

You may just want to wait a few months to see what the manufacturers come up with for their spring releases. They all fiercely compete against each other. If you're in a northern state, it's going to freeze soon if it isn't already frozen. Some of the western states are already seeing freezing.

 

[merlin01]

I'm from europe.

So i need a VLF detector then, because it will make me dig less trash ?

You guys must understand that some info, from my point of view is contradicting, that's why i am always asking seemingly stupid questions. Think of explaining it to a 5 year old.
