VDI numbers Fors CoRe

[eureka77]

Anyone have kind of a ruff cheat sheet as far as VDI numbers and their correlation?
What do 10k rings come up as etc. I know there are defining factors such as soil type, depth, etc. but just a ruff idea? In process of doing a test garden but any free time I get Im out there at a park trying to get time in. Only found clad so far and they've all pretty much been VDI 83. So until I can get my test bed going Im needing yalls expertise if ya wouldn't mind sharing if you find time, Thanks and HH

My experience in sandy, low-mineral Florida soil:
Nickle usually a solid, unchanginging 56 or 57 BUT can be as high as 59
Zinc penny 82
Copper penny 83
Very shallow penny can be as high as 85
Dime 84
Quarter 88-91
Multiple coins in the same hole can be anything between 58 and 90
Just found a sterling silver ladies ring with small amethyst stones that rang in at 88-91
My gold wedding band is about a 75
My sterling silver class ring rings in in the 92
Found two nickles and a penny in the same hole that rang in at 67
My understanding is that thin gold rings can ring in anywhere from 10 to 70
Symmetrical shaped targets will give a clean solid sound and stable numbers
Asymmetrical targets will give you sounds with rough edges and jumpy numbers
Multiple targets will display multiple numbers, with the last target seen being the last number displayed
Believe your ears more of han you believe you numbers
If your gut says dig it, do!

Bottom line is, if you don't want to pass up a really good find, you need to dig it all. Much easier said than done, believe me I know. I have a park nearby that is apparently not searched much, and it is a lot of fun to just cherry-pick all the solid coin numbers but the more I learn, the more I understand I really need to stop cherry picking and dig it all. I am positive I have passed up multi-dollar value finds to pick up pennies! Truth be told, though, it is so relaxing to just concentrate on the sounds, the numbers and the finds that the enjoyment is worth far more than any monetary value of my finds. Enjoy, and happy hunting!!!

Flbchbm is right on with the numbers in my experience.
One thing I have found is that a bottle cap will come in at 84 but, as you circle it while swinging over it, the #s will quickly drop to a low # and then back to 84. Handy trick to know. Some large caliber rifle cartridges .308, 30-06, etc. will come in at 82. .22 shells come in all over the place but most often about 51. Thing is, they have a very distinctive, super quick, short duration signal. HH

Yep. 80 - 85 can be a crown cap but sound will end with a grunt if you slide off the target slowly with the front edge of the coil
Or
It can be a flattened aluminum screw cap
Or
It can be a smashed aluminum can at depth (6+ inches)
Or
It can be a can lid
Or
Or
Or
Or
Modern pull tabs hit at 58-60
Beaver tails can be anything from 50 - 75 depending on shape and depth and orientation
Foil can be anything from 20 to 90+ depending on shape and amount of material
Flat steel/iron can be anything from 10 to 99 depending on size, shape, depth, orientation, amount of corrosion
Nails are usually less than 20ish
Unless they are made of aluminum, then they can be 45 ish

Dig it all and recognize the patterns you find. Then on days you want to be selective you can do it with confidence. Sort of......
