Bottle Cap VDI Reading

[Ronk]

What are the VDI numbers for the old style bottle caps on G2/GB? Not the Screw on caps.

i find them in 70's to mid 80's most of the time i am disc-ed at 68 so others may say lower not sure but thats what i know.

I'm not one to remember the numbers that targets were...I do know I have dug just about every solid repeatavle signal and I have a vast collection of junk as well as good targets.

I get upper 70's here in Northern Calif.

That is true when using a good old TR-Disc. model that has what I refer to as "True Progressive Discrimination", and even though most modern motion-based Discriminators (analyzing both ground signal and target signal) will respond with a higher-reading in the

Monte I've read about your EPR and Quick-Out methods but the detectors I have now doesn't have a problem with bottle caps.One of them is the Classic-3SL I bought from you.I was just curious if the EPR and Quick-Out would also work with other questionable targets using a DD coil. A little later on I'm thinking about about getting and Omega because it uses the Concentric and DD coil and to me I think you get more for your money that way.And who knows...Maybe sometime they might make some in-between sized coils for it.I think a 5 inch and 7-8 inch concentric would be great for the Omega! As I said a million times before..Give or take a few hundred thousand...I search just like You in some very trashy places and love those smaller coils too! In fact that's just about the only way.I agree with all those folks who said there are more Good targets that are masked by junk than targets that are deep.Of course I also believe there are Good AND Bad targets that are beyond any detectors depth capability.No one knows what changes have been made in the past to the ground they search.But I know there are plenty of good targets that are probably shallow and masked by junk that a lot of people pass up because they don't want to dig even ONE piece of trash.That's fine with me! For my next ID detector it will probably be the Omega for reasons I've mentioned plus the Great reports I've been reading! You're right about one thing...Those Bottle caps never had a chance with those TR's! Anyway,I mainly wanted to know if your EPR and Quick-Out would work with other targets.

Of all the motion-based Discriminators, I have found the Classic series to be some of the best at ignoring (discriminating or rejecting) most typical bottle caps. It doesn't matter which brand or model, the Classic's do extremely well!

I was just curious if the EPR and Quick-Out would also work with other questionable targets using a DD coil.

Yes, however let me just clear the air, so to speak, with regard to my search coil preferences. As a rule I am just not impressed with most Double-D coils, or at least with the performance on most models that they work on. This is especially try of larger-size DD coils, such as anything from about 8" diameter on up. The DD design can have too much falsing or signal confusion, if you will, on targets that are shallow. Things like coins that are within 2" or even maybe 3" or more, depending upon the model and settings.

The EPR and Quick-Out techniques can work okay for their purpose is to help audibly and visually "classify" iron from non-iron targets. Different coil dynamics and detector circuitry can also make a DD coil respond farther from the coil's edge, especially with iron, and it just takes a little time to learn more about how a particular detector and DD coil work.

A little later on I'm thinking about about getting and Omega because it uses the Concentric and DD coil and to me I think you get more for your money that way.

I like the stock 5

Thanks Monte for clearing up a few things about the the DD coils! I would probably use the Concentric Most of the time but since I use smaller coils more often than not I would also get the 5incher DD.I Might use the 11"DD IF I were in in open fields or IF I was in an area that had very bad ground for for the most part I would use the stock 10incher elliptical for general purpose and ground coverage and the 5inch DD for the trashy areas which Most areas I hunt are. I also noticed that I haven't hardly heard anything about those using the GB/G2 for nuggets anywhere.Maybe they have but I just didn't read it anywhere.It seems most are using it for Relics and lower conductors in iron.For general coin hunting I still think the Omega is the way to go. I have heard others say that they DID lower the sensitivity on the Omega and it still performed fine for them and got good depth.
I know I can run my C3SL on Max Most of the time even under power lines with no EMI problems. As far as bottle caps with the C3SL...using any concentric coil all I get is small clicks or pops when going over them and that's about it.Now IF I am in the Black-Sand mode with min disc Then the B-caps will give a more clear signal.Just using the Black-Sand without bad ground still gives me and inch or 2 more depth.
I almost forgot about the 8 inch concentric for the Gamma.Will it work on the Omega or have you used it on it already? You're right...6-6/12 concentric would be great for the omega.You can Never have Too many coils to chose from!
It's been too hot and dry to get out down here and the ground in places is just like powder. We desperately need some rain! Thanks again for the coil lessons!!! Much appreciated!!!
