Did a test using pure gold on a deus

[pasttarg]

Using some wads of gold leaf of 22 to 24 carat I tried all the programme s and got readings of 28 to 31 on the Tid so if your disregarding anything under 30 you could be missing gold of good purity ..the tone was about mid tone too ..gold alloys can be higher and just about anywhere on the Tid...mates of mine say don't bother with anything under 30..these are in air tests !!

[oldartefact]

The billion dollar question being "Did they have gold leaf in antiquity?" And if they did ... think I will leave the 28-31 numbers for fitter detectorists than me to dig!!! optimism is the name of the game ... and all those hot rocks would see me quitting within weeks ... if not days!! <:-P <:-P <:-P

I use a CTX and my detecting partner a Deus. We regularly signal check on slow sites (which are most of them ) to break up the monotony and it has thrown up some surprising anomalies with both machines. This is particularly true with signals deeper than the reliable target ID depth. We have both discovered the hard way that it is perfectly possible to ignore keepers if you unquestioningly believe everything that your machine tells you.

dig numbers only miss finds ive never looked at a screen read out yet if the detector makes a noise I dig it out

Apparently they did That's how they applied gold and silver plate to some of the coinage at the time.

Interesting to see these anomalies

If i dug every noise my finds pouch would be crammed with hotrocks and 4-hole buttons ... as they say up here in yorkshire ... if you dig all the hotrocks you wont find much brass!!!

On beaches certainly I am the same but on land I am slightly more discriminating (boom, boom ).

I couldn't understand the first 14 words due to the grammar but the following 10 words make more sense if you want to dig every signal the machine indicates, but I suspect that some detectorists will pass on some signals as being "trash" or ferrous.

Rightly or wrongly, I dig all the signals the Déus suggests are "good" and our results are surely testament to that fact

I personally don't put too much emphasis on ID numbers, especially as buried items read different, I tend to pay less attention to anything under 35 unless it sounds very sweet, mostly being foil or coke. However I once had a loverly sound that was faint bust crisp and no ID numbers at all, it turned out to be a deep small Henry VIII hammered so just goes to show.

To be honest a lot depends on the site, if hammered are turning up then I dig a lot more dodgy signals than if it is a poor site with lots of trash.

I do wonder how many good finds are missed that read very low, but I suppose it is a bit of a trade off depending on the access to the site, i.e. If a club dig or one off visit to a rally etc. If your own permission, can always dig the ruff ones another day. I am currently doing the later on a done bit of pasture and just got my first early English Jetton there.

Spot on Dave, there are always trade-offs.... the amount of times I've left a scratchy signal only to return to it and find that it wasn't foil or ferrous! rl;

I am off out onto a new field that has an array of BA ring ditches, Saxon cemetery nearby and a medieval church ... I will be digging those -30 signals today at least sw; Liam

A few years ago I found a gold hammered. It was an OK-ish signal on the Tesoro I used at the time. Now I didn't have a read-out available, just sound. I also knew that beyond any kind of depth the tonal discrimination (I used my machine on all-metal and tone to try and get a bit more depth) was unreliable. So out it popped. Hubby had walked over it with his Whites DFX. Poor tone and total trash readout on his screen. Which 'confirmed ' to him it was rubbish...whereas I only went by the tome which had just a tickle of a good signal in the mix.
I concluded that number read-outs tend to work to stop people digging iffies rather more than they persuaded them to dig them.
Silver is, of course, easy peasy and as long as you have your machine set up in any kind of usable fashion you won't miss it at normal depths.
Gold, even quite shallow gold.....and a lot of coins are very pure gold which makes it worse....is much more problematic.

I dig much more than hubby. I find lots he'd leave in the ground. I know some fields are very 'busy' with hotrock, trash, iron etc. But that surely means there is more, rather than less, chance of goodies being there. It doesn't make sense to me to leave Iffy signals just because there are lots of them. I simply adjust how much ground I want to cover and am very thorough over a small area and try to pick it clean.

A few wads of gold leaf is ample to test the Deus ..the tones were mid range and the slider bar is lowish so not much else to go on if it's a gold torc under your coil...giving you a 29 tid

Some worrying info there but we may as well know what may escape our grasp. My Iceni stater came up as a lovely 82 on GMP but its a lot fatter than a thin gold hammy, though that number 82 is now forever etched on my brain! My friend Godfrey and I went over a recent hoard site in advance of some serious ditch clearing by the farmer and found another few romans, one being a clump of around three all fused together and they came up as a very clear 83. When he got home he found a neat coin sized hole in his pocket ..... and no coins
However, we know where they will be found and the three hours detecting with a good friend in beautiful scenery and gorgeous weather is the real treasure to be found these days

Today 20 of us were out on some quietish fields ... through desperation we we all digging every rubbish signal available, and guess what... apart from one silver, 3 grots and a broken fibula ... very little more came out. That said I am guessing that 20 x 20 Rubbish signals were dug to retrieve that lot. I keep telling myself that the next rubbish signal is going to be the find of my life .... but sadly its always rubbish ,,, just like my Deus said it would be. Thats the power of optimism for you!
