VDI Information

I have seen several request on the forum for information on VDI for coins and jewelry. I also hear people say I searched this sports field or that park or an easement and found this or that.

If you have an opportunity let other people know what VDI you got on this ring or that coin or some other piece of jewelry or token. It sort of seems like people like to keep those things a secret. In addition to that I read a post about someone searching a sports field and found four or five rings in one hunt. Let the folks on the forum know the most likely place to find treasures like that. Something like I found a silver ring in left field and it VDI'ed 89, or I found a gold women's wedding band right behind the dugout and it VDI'ed 53. I don't think those kinds of information are giving away anyone's secrets. No one is going to ask what park or baseball complex you found all of this stuff in.

In that light I will say I was hunting a baseball field the other day and found a 2.5 gram 14K gold women's wedding band in right field. It VDI'ed 51-53-51. That to me is a must dig. It usually will turn out to be a pull tab, but you must check it out. Not many pull tabs in right field.

I usually hunt baseball fields using the grid method. I will go north and south in right field, then I will go east and west. That way I know I have covered it as well as I can. Think about how elusive a small gold ring or ear ring can be in a 2 or 3 acre baseball field. Takes a lot of luck and good detecting skills to find something that small in that kind of area After I finish one out field area I will go to the next area, like center field. If you cannot finish the entire field or area in one hunt, pick out a marker like a light pole or gate and remember to start there on your next opportunity to hunt.

I also found a .925 silver band right along the fence line of the same ball field just past the 1st base dugout where spectators sit in folding lawn chairs to watch
their kids play. It VDI'ed 91 on the Pro. That is high for sterling, but anything between 82-92 could be silver. I find most of the clad and silver finds in a sports park will be 4" or less. Gold can be any depth depending on the weight of the piece. My gold wedding band was about 3.5 inches.

Go check out a baseball or softball game and notice where all the people congregate to watch the game. In addition look for trees near the dugouts where the next team to play is gathering and storing their equipment for the next game. I find lots of clad there.

Hope this was informative. ask any question and I will try and give you my most honest and accurate answer.

Happy Hunting. Its a great hobby.
 
No one is keeping the VDI numbers a secret, it's just that they may vary somewhat depending on what part of the country you are detecting.

Please see this previous thread as it is a good discussion on what you are asking.....

I hardly ever look at the VID's, just give them a cursory glance. I determine when to dig or scoop with my ears. If it sounds good, dig it. The VID numbers are kind of fun to play a guessing game with, but that's about it for me. Good tone, dig!!
 
The link posted above references a thread that I started a week ago. There were some responses worth reading, but I have to agree with sparkster - AtPro users are either not tracking their VDI numbers very closely or they are not sharing them. Everyone who has detected with the AtPro knows that gold can be anywhere from the low 40's to the mid 60's - silver ranges from the upper 60's to the low 90's. I have yet to see anyone post a VDI reading for Platinum. Based upon my experience with other detectors (Minelab Explorer XS and eTrac), platinum comes in lower than even small 14K items.

Don't interpret this incorrectly, I am not saying that AtPro users are keeping secrets. I just wish that collectively, we could come together as a group and no kidding document our VDI readings. There are times when we all have limited time to hunt and we would like to tune in on those target VID's that offer the highest probability of success. I know this chart is rather irrelevant here, but my other detector is an eTrac and the below spreadsheet/photo are indicative of what my colleagues in that forum have assembled. Note - I had to use a screen capture because the three original files (US Coins, Gold and Silver) are excel formats that are not supported here.
 
I would also like to see a spreadsheet that others could collectively add their results to. I have found a platinum diamond ring that came in at a solid 43, it was marked 10% irid plat with 3 small round diamonds and 2 larger flawless baguettes. It appraised at $1895.00!. I have found a 4mm, 24 inch, 14k necklace at 23.4 grams that rang up a solid 43 also. Yesterday I found a large 14k mans gold nugget ring that came in at 51~53, thought it would be a nickel. I have found about 28 silver rings that came in at anywhere from 80 to 90, with only one coming up at 74. Could someone create a spreadsheet that we could download and post our individual results for others to add to their results?
 
Seems to me that 43 to 60 is a good gold range. In the recent past, I have avoided digging anything lower than 45 because there is literally a ton of bubble gum wrappers and thin foil that you peel off of the top of juice containers. Guess I need to revise my strategy to include 42-43 and above. Thanks.
 
I'm like the others...seldom do I pay attention to numbers. I set my Pro to Pro Zero and iron disc to 25 to 30, and if it beeps I dig. Our dirt is so bad here that it always causes things to read wrong on the numbers. Some objects read higher than they should and some lower. So it pays to use a metered machine like its a non metered one.
