Anyone notice when ground is dry

[Anonymous]

That many rusty bottle caps will read top right and give the same signals as a silver quarter.
I notice this when it has been real dry while running sensitivity in the 20s my S12 on my Explorer has ID these as silver quarters, one was not too deep so I used the X1 probe and it didnt do this. I feel that the power of the Explorer and the bigger coils are causeing iron object to read good on the meter and the tones when the ground is very dry. I notice if I turn down the sensitivity it helps abit.
When it was real dry like this my Sovereign would ID the rusty bottle caps as nickles. My GTI 2500 was real bad as IDing these as coins and dug a lot of them. After the ground got wet there was no problem.
Just wanted to see if anyone else has notice this.

I had a Buffalo Nickel I.D. as a bottle cap the other evening. The ground is super dry here also. Who knows though, there may have been a bottle cap under or somewhere near the nickle. It was a different and far better sound than a bottle cap tends to give, but the x was locked in right at the bottle cap area. The sound was the only reason I dug it at all.

Well, if you use a DFX you get 20 levels of "Bottlecap Reject".

Ive never seen a bottle cap read higher than halfway up the screen myself.. I have had them bounce into the nickel area though.. dry conditions are usually good for iron ridden sites, I believe you get more masking in high iron in wet conditions.. Its a good idea to rehunt all your sites when conditions change, What does make me baffled is why bottle caps read far right.. thats telling me they are very low iron content.. but they are iron based?

That rusty botle caps will read that far right as they are made out of iron. Like I say I notice this before when it was dry with my GTI 2500 I used to have too in the same park and figured it has to do something with the ground minerals with the rusting of the caps. Now on the Sovereign we would see them in the nickle areas and some even in the pulltab when the ground was this dry.
It has to have something to do with the power of the Explorer too as the 12 inch coil I was using did it more while my S1 probe wouldnt do this. I get a few with the S 8 but not as much as with the S12.
I notice something with the new bottle caps that come on the new beer bottles and that is they have a differnt metal in them as they will show up in the pulltab area, must have alum in them, but the ones I was getting were the older ones that are rusted bad.

Hey Jim,
I'm mystified too. Would like to hear an explanation why ferrous bottle caps are always low right. I've found with iron falsing on nails and other stuff that icon can also bounce low right. Or just low and bouncing left and right. I've been trying to dig more low signals looking for rings and nickels. Not sure about rings but I'm guessing I've passed up quite a few nickels. They just have to be there given the other stuff I'm finding. Not one V nickel yet. Air testing nickels is pretty repeatable in one area, and find some shallower ones this way, but deeper ones seem to bounce more. Sure dig alot of pull tabs trying to figure this out. Any Advice?
