platinum on the F5 (or any other F machine)

[dfmike]

Anybody found a platinum ring on the F5 or any other Fisher detector ? If so, what is the VDI reading or in what category of metal will it find itself on the detector ? Thanks.

Pretty much the same as gold...maybe a bit lower than that metal but not much.
No way to tell you exactly where it will come in because like gold that all will depend on the size so figure from foil to zinc.
Most report the most common area this rare metal is found will be nickel and under.

Never found plantium, I was thinking what products you buy off the shelve that would contain plantium so you would have a " test" sample and the only thing that comes to mind is they make a plantium tip spark plug for cars. Sounds like you are setting your sights pretty high looking for plantium, if you find any please post about it love to hear about that.

I am with REVIER, size is everything, if you are hunting gold and finding some and you go over a platinum ring you will find it as well.

I heard that platinum gives real low numbers, and of course the size matters as mentioned, Its on my list to find one

Platinum woman's wedding band comes in at 20 21 on my f 75.

I asked because I found a small ring on a beach and it gave me a solid 38 on the F5. It looks like silver to me but it couldn't be at 38. It could be white gold I suppose but my mom's wedding ring is made of white gold and the ID jumps a lot (I suspect a nickel/gold mix that drives the detector bonkers). There is a symbol or some writing in the ring but I can't make it out. Perhaps it's just some cheap costume jewelry...

Anyway it's always good to know platinum is in gold range.

dfmike, it might be worth the time to take that ring to a jewelry store and let them test it, never know it could be a precious metal.

You will not be able to ID what type of metal with a detector. If it is platinum it should have some kind of marking inside the ring. Being platinum is a step up from gold I would think it would be marked.

You can check online for platinum markings, I don't know what the markings are for platinum.

I have found several white gold rings with Fishers.
No jumping...solid stable signal on every one but lower than yellow gold would be at the same size so the alloy should not matter to detectors.
Don't assume the characteristics of one piece of jewelry is inherent to all and you will find more.

The two rings below were both solid and found by my F2.
The yellow gold on the right was a 35...the several sizes larger white gold ring was a 24.

According to a link I found, platinum is either marked PLAT, PT, 900 or 950.

White gold can be an alloy of gold with either manganese, palladium, nickel or platinum. Sometimes other metals are added as well. Wouldn't it be possible then that the ID on most detectors could become unstable depending on alloy content and quantity of secondary metals present ?

I will guess no, mostly because I have never found a jumpy white gold ring yet and I have found a few.
Also, unlike having a tab sitting on a coin that could indeed throw out a skewed signal because there are two distinct metals in play, no matter what white gold is made of it is an alloy...a total melted and fused mixture of gold and that other metal which in my opinion makes a third solid signaling metal in its own right.
I have gotten jumpy signals air testing rings in the past too, I believe this is because I moved it around the coil's scanning field slightly when doing it.
In the field outdoors in the ground the ring stays still, the coil moves around it which may sound like a similar thing but I am able to get precise movements with solid signals easier than moving targets by hand across the field.

REVIER,

I had to test that white gold ring on my mom's finger while she was wearing it. The ring can't be removed anymore. If I could test it properly I would. I find it intriguing that the ID jumps around like that and it's not just a small jump of a few numbers. I have found a few rings and none of them exhibit this behavior but none of them are considered white gold. It's either 10, 14K gold or .925 silver and those have super stable ID when air tested no matter how I move my hand in front of the coil.

White gold is NOT more jumpy than yellow gold.
All my experience tells me so...something else was going on here.
