Thread revival. There is a bunch of new F2 users around (me included) figured I'd revive this to the top for some of them to see

As long as this thread is back, here is a post of mine that is over on the F2 social forum with a more complete list about target VDI numbers and a few other tips.
For any brand new users just do an advanced search using my name and the words, F2, sniper coil, gold and others and many of my posts about using the F2 should pop up.
Just message me and I can send you a list of some of the more informative ones if you would like.
****************************************************
These are numbers of targets I have found for the most part, a few are from other hunters on objects I have yet to recover, like some relics.
I will add to this list and also add any useful tips as I think of them.
All numbers can be slightly different on all F2's, they seem to be calibrated a bit different from the factory and soil conditions in different areas of the country can affect these numbers, too.
For instance my regular nickel signal, (and I have dug them from the high 20's to the mid 30's), is usually a 33, but for someone else this could be a 34 in most instances.
I have dug targets in Michigan, Alabama and Kansas and some numbers are slightly different in each area.
In Alabama my normal, standard zinc penny signal was a 59 or 60, here in Kansas it is now usually a 60-62.
Just take note of what your normal numbers are on all standard targets and go from there.
COINS
zinc penny..................59-62
copper penny..............70-71
clad dime.....................71-73
Steel war penny............74-76
nickel...........................33
clad quarter..................80-82
half dollar.....................89-91
large dollar....................92
Indian head penny.........zinc...different areas
war nickel......................34-35
Gold coins can actually come in anywhere from foil on up including under dimes or quarters depending on the size.
Silver coins, add one number to each reading, minimum.
For example a silver quarter, 83 vs 82.
Coin spills will be a combination of numbers depending on the content and amount of coins.
multiple zinc pennies........over 62
2 dimes..............................74-76
3 dimes...............................76-78
2 quarters............................86
3 quarters.............................88
Different combinations will be a lower number than the largest coin in the group.
Example...A quarter, a dime and a zincoln could be in the 70's, there will be little bouncing unless they are spread out over a few inches, and you should get a solid tone.
RELICS
Depth will affect these numbers, among other things
2 ringer ..........59-65
3 ringer ..........55-65...I found one and it was a 61 just like a zincoln, another was a 58
eagle button ...51-65
flat coat button 64-67
musket balls......tabs
mini balls..........foil on up
JEWELRY
Silver rings, religious medals and other silver objects should come in somewhere between the dime and the quarter areas if they are normal sized and depending on that size.
Smaller objects like small thin kids rings or small studs and earrings can come in as a zinc signal.
Gold rings and other gold objects like crosses can come in anywhere and everywhere from iron to zinc depending on the size, karat and alloys it is mixed with.
Really tiny objects like studs or small clasps on chains can come in at iron numbers and can usually only be picked up with the sniper coil.
A little bigger but still small objects and small thin rings can be at foil, a little larger at nickel, larger still at tabs and very large like class rings at the zinc level.
Purer karats will be higher than lower levels...An 18k ring will show up a little higher than the same size ring that is 10k.
Rings of any type that are split or open can come in anywhere, can be a jumpy signal and might be hard to pick up at great depth because of the way detectors work and something called eddy currents.

The same effect makes it very hard to find most chains of any type or metal so we need to be lucky and hope we scan an end with a clasp to find these.
The same thing can happen with other objects that are not chains but are still open like solid bracelets.
Chains for me have come in anywhere from iron on a tiny, thin gold clasp on an extremely thin gold chain, all the way up to zinc on the clasp of a very thick men's bracelet, but not one silver chain of any size has ever come in as a dime or quarter high tone signal.
Except for that one signal on that thick bracelet which was a 61 zincoln number, every other chain has been mostly from foil on up and always a true trash signal.
I dig it all because in cases like this and most others you just never know till you dig it.

Last 3 I got were around the same in the ground, but air testing they ring up higher in the low 60s.

New to the F2, huh?
Brings back memories from when I first bought mine as a backup "only"...didn't quite work out that way for me.
I had no idea at the time how good and productive this thing was, or how good I would get with it because learning it was so much fun.
Sometime you just "click" with certain detectors, and the F2 and I sure did.

Over $1000 in clad alone in 3 years, and that was just a byproduct while I was looking for other stuff.
Here are some links to some other good info I learned about this biz in the last few years, and a section on the F2.

Digger - I've never pinged a steel war penny, but curious why the VDI is so high (higher than copper)? Would have anticipated it to show up more like iron.
Thx.

Steel and rust.
I have found 4 in my time, or think I have.
One of them is just a totally rusted disc at this point so until I use electrolysis or something I won't know for sure.
The other 3 I found on one great hunt, something I don't expect to ever happen again.
All three were pretty crusty and rusted, but a trip through the tumbler and I discovered what they were.
All three were weird signals slightly higher than a dime, at least a 74, and in air testing it tested at those 74-76 numbers numbers and I was confused till I tumbled them.

Thanks. New to MD'ing and trying to understand what to expect on the F2 and AT Pro.
Have now dug a couple hundred coins, including silver.. Have also dug 10,000 tabs, but still chasing the elusive nickel.
