Deus vdi chart

[Emrys]

hi
This appears to have been mentioned before but with no actual results from what I can see,
Please can some kind person post up vdi numbers for the coins Romans and gold etc
I've noticed someone requested this a year or so ago and received replies along the ones of if it sounds good then dig it which is good advise and all that but I find the vdi knowledge helpful as well
I printed it off for my old machine and kept it in my finds bag so I could revert back to it when I needed it
Much appreciated
Thanks

I've only had my Deus a couple of months but I find that if you are going to look at the numbers then it's probably best to lump them in blocks of 10. I also find that as the object surfaces the numbers can change quite a lot. So far, for me at least, Coke and silver paper comes in at the 20s. Very thin, tiny broken sides of shotties etc come in the 30s and perhaps slightly larger pieces of very thin scrap in the 40s. Small buttons are usually in the 50s. 60s which tend to be interesting numbers as it can be tiny gold. 70s are usually the small roman coins. 80s are the decent sized hammered. 90s are tricky- 95 and above and it's usually deep iron but be careful as it can be a nice silver shilling. As you see, you can really only safely ignore the low 20s. It depends on the site and what hopefully might be there that governs your judgements as to whether to dig or not. Hope you find this useful but bear in mind that I'm still learning myself, and apart from the low 20s I tend to dig everything.

I go buy type of metal

ie copper 80 to 90

silver60 to 75

aluminium 35
coke 20 to 30
its a ruff id scale

If you change frequency the numbers all change so it's really difficult to give any accurate vdi numbers without giving them for all frequencies

In my experience though anything under 35 is plop

Hi
Thanks for info especially Jamie's info on plop lol
I noticed with my garrett at pro generally anything over 38 was a digger so looks like it's more or less the same I found a great vdi ref for the at pro that had each coin number eg pound coin was 75 etc as I'm hoping to batter some Roman sites this year I were wondering what these coins come in at and also hammys (not asking much I know )
I found a cartwheel penny a couple of weeks ago and it came in at 94 and I thought the number was too high and wasn't going to dig it I actually walked past it and found the target again on my way back and decided to dig it in the end not expecting much so imagine my surprise when it fell out rl;

Your question cannot be answered as the VDI on the Deus will only give you an indication to the conductivity of the target and this can change dependant on the ground conditions, depth of target etc, like most people say if it sounds good dig it

Just answered my own question
But will post for any other users
I didn't think to look on you tube there's a guy doing an air test on hammies

Personally i just go by a possible good tone. Lots of things can influence vdi readings. If i hear a weak good tone, or something worth investigating, i will remove a layer and then re-scan. Just my opinion, hope this helps

I understood that Deus V3.2 keeps the numbers consistent across the frequencies. Really, I agree with Monkeyman101 and its best to go by the tones.

I was out today and again noticed how the numbers changed as I dug the signal. When I was in one area where silver paper is a problem I took the chance and ignored all the 30s. A rose farthing came in at 50 so I was pleased with that. The ground was a lot dryer today and I had the feeling it was costing me depth and clarity of signal which had been notably excellent on the site previously when it was damp.

I just had a hammy come in at 10 on gm power on water logged ground.
don't know why I did dig it. must have been a good two way sound.

Try it for yourself .. Try changing programmes AND frequencies

The numbers change .. It's annoying

I cant remember where it is on the sub menu but I'm sure you can lock the VDI so a target will give the same numbers in 4,8 and 12 kHz as it would in 18. I was going to do this when I got mine but after getting used to it, I now go by a simple rule of thumb. Very low numbers with iron tone or 97 and higher, don't bother digging. Everything else with a fair tone = dig. I cant help looking at the numbers but they mean very little. As has been said, the numbers will change depending on depth, orientation etc.

"ID NORM" is the setting you can enable to get consistent VDI numbers across all the frequencies. I should probably do that myself And maybe set the clock properly too

It's in the same place where you can set whether to have that horseshoe graphic or the pointless curve thing that shows you the reactivity setting - go to OPTION, then CONFIGURATION, then PROFILE...

Mostly modern coins if no year given -
