Think it came up at 6 when I tested on the nox, but that was an air test so not really representative.

I dig the low numbers on the nox as well, had a gold ring come up as an 8, with the nox I dig every positive signal that gives a solid response.

My James 1st half penny was a 13, so higher as its silver but still well in the foil range bacuse it's so tiny.

My Eddy I farthing gives 8, though a cut half 6.

As far as I understand: conductivity and conductance, where as conductivity is the intrinsic property of the metal, conductance is a property of the object. So a thin high conductivity metal object may have low conductance.
The discriminator or the target ID is a reference to the conductance of the object. That is why you cannot discriminate metals, you discriminate metal objects. In other words a whopping gold coin gives you a high reading where as a thin gold object gives you a low reading. Hence you might be discriminating gold thinking it is aluminium foil.

An interesting thread and thinking about it, all 4 gold finds have been with the nox.Now I’m not suggesting it’s better than the other machines I use for finding gold,I’m sure it’s just coincidence,or is it?

I've only fold gold on land with the deus. I've found gold on the beach with the nox, and with the explorer, but the deus isn't the best choice on the beach if you have a nox or explorer!

Out of interest was the sound like foil or was it cleaner/brighter ?

It was scratchy as all hell and sounded like the bits of canslaw I had been digging up all morning.

Wasn't the best conditions for clear signals though, longish stubble that was keeping my coil a fair few inches off the ground and sensitivity at 99 to compensate.

When I dug it out the signal cleaned up nicely and it was a nice tone, although a lowish one.

My two gold finds this year, a sovereign and a bracelet came in at 17 & 18 and probably any detector could have found them. But maybe certain detectors are better on small gold?

Who knows,I’m yet to find anything on the lower numbers,an 18ct button stud came in at 8,that’s the lowest so far.

Last year I found a modern 9ct signet ring with the centre "stone" missing ...That ring came up as either a 9 or 10 on the Nox...the posy ring I found earlier in the week came up a very strong 23...I actually expected to dig an ali drinks can lol

I have been told that gold gives highly variable signals depending size, shape, grade of gold, and soil conditions and can essentially come up in a multitude of places on the TID...

I tested some gold rings a while back from thin to thick band. A 9ct was 7, a 14ct was 9, and three 22ct's were 12, 20 & 25. I've never found a gold ring yet, but hope to!

Sounds a bit like shotties,lead or even hammered coins.
I set a new personal worst yesterday with a shotty coming up at 4/5.

I came to the conclusion a while ago, you can't really rely on TIDs because they are so variable...Think about the times when you have a deepish target, and the audio and the TID change as you dig and remove soil....in these instances the target is "constant" but the response from the machine changes....The same thing can happen if you swing over a target from a different direction...

These days, I therefore don't pay too much attention to the exact TID, rather just use it to try to predict what I am digging for a bit of fun....

Yes ,I do the same but always guessing the worst possible target possible,rather than wishful thinking.

Going through the ranks of the learning curve in this hobby I have no doubt made many mistakes and one being notching out iron etc . I had my 1st detector being an ace 250 and notched out everything up to the pull tabs . One day out of curiosity I dug the pull tab signal and there was a hammered coin ! Lesson learnt the hard way and I wondered how many I had missed in the past .
Upgraded to the Quest 40 , lovely machine and hammered coins were a sweet high pitch two way signal , nice and sharp and rang in on the 60-70 if you were following numbers however I got lucky one day and had a slightly grunty signal which I confess I almost walked away despite it being a stable two way signal and ran in low 40s which was usually rubbish. It was a gold half sovereign !
Moving up the stakes and using the Deus Lite on Hot Programme again a game changer . The buzz of iron which used to irritate me now I find sharpens my senses and I dig almost every signal just in case . It takes a while to get accustomed to the different sounds and I have yet to find gold with the Deus , so a good thread and interesting to get the many perspectives from other machine users .
One of our club members found a bronze age axe head hoard a few years ago . He was saying exact same thing , it gave an iron grunt but something about it made him dig just in case just his experience and curiosity gave way and he admitted if he was in a slightly different frame of mind he may well have ignored it and walked on . Easy done but his advice to me was if there is any doubt then dig everything as it takes a matter of seconds to dig a hole :thumbsup:
