Manticore or nox 9ct gold and other gold numbers

[Old white]

I’ve been testing gold with the Manticore it’s having problems with a 9ct gold ring which is showing as ferrous see picture.
The gold I was testing is correctly hallmarked.
My nox 800 had issues with it as well.

Does anyone have any numbers for in situ gold for the Manticore or even the nox? not test garden but un dug artefacts. Just so I can get an idea of what to expect.

The 24ct gold coin I found the other day had scratchy audio 30-35 probably due to ground conditions, 2d display showing blob correctly on the non ferrous line, when dug it was 60.
Thanks for any further gold info.

Ignore all numbers, they're a useless gimmick Dig all two-way signals regardless of tone.

Cover the screen with tape if you can't stop yourself looking at it.

I don’t look at the numbers much I was detecting in the 90’s when there wasn’t any numbers on the machine I was using.
The only thing that’s got me thinking about this is the gold angel from the other day if I went by audio I wouldn’t have dug it it was scratchy and faint, no solid two way, the numbers were bad so didn’t add anything in the way of extra info, the only reason I dug it was because there was a non ferrous blob on the 2d display and because I do dig the odd sketchy target, it has paid off in the past. If I was using my nox I wouldn’t have dug it I’m pretty sure it would’ve come in as a low tone with bad audio and barely a two way I would’ve thought it was trash.
So I’m information gathering for what peoples experiences are when digging gold. And for an explanation as to why a 9ct ring would give an iron grunt and bad audio on three machines.

I don't cover numbers, they do have their uses, but they won't help you decide whether a signal is gold or not. Depending on what it is, the size and the carat gold can give any number on the Nox between negatives and about 26. I would expect the spread to be similar on the MC. You have to look at all the information that the machine gives you and then use your experience to decide what to dig.

In theory the 9 carat ring should be a pretty good signal because the gold content is less than 40% and the rest of it will be silver (high conductor) so a bit of a conundrum

Is it possible that it is a higher carat ?

Incidentally my 9 carat ring is a solid 19 on the nox.

All things being equal higher carat generally comes in lower.

Thanks. Yes it rings at 20 on the nox for me too and 18 on the Manticore out of the ground, the problem I was having was when I put it in the ground in a metal free area. Not sure what the issue was, I’ve given up on it for the moment.

Hi yes I know that the higher the carat the lower the conductivity/response that's why I was wondering if the 9c ring was actually a higher carat due to Old White saying that it registers in the ferrous range.

In reply to the original post when I first got my 800 I got a solid signal of 7 on pasture which I thought was a bit too low to dig but since I was just learning the machine decided to Investigate.

Glad I did because up came a lovely 18 carat Georgian fob seal . Once out it came in at 8.

I never used the numbers at all on my old detector as they were too jumpy. I was hoping that with the manticore they may have been more helpful but really they aren't.

More stable prehaps but my gold 9k good chain gives me low teens vdi and a lowish tone... Some-what identical to most foil.

Additionally a vast vast array of things seems to come up at mid 40s from silver 6 pences, pull tabs, small lead, bullet casings. And a load of other tat..

I allways check the numbers but they wouldn't ever help me choose to dig or not.

But the issue with gold ring showing as Ferrous for you is more concerning.
Do you have the all-metal mode enabled? As I've found sometimes my manticore will give red line, ferrous and non ferrous tone at the same time.. one would only hear it if all metal is enabled..

[Old white]

Yes all metal, red line and grunt and nox similar rubbish signal must be down to the ring. It’s just one of those things .
