Hi Mike
I tried as many as 70 different rings and a lot of other types of jewelry, I tried the pull tabs I have collected and have about 100 or so and they end up mostly registering as basically two types that are slightly in different conductive ranges.
Most of the gold rings I have tested are in lady size and thinner than a man's ring would be.
All from 22k to 10k gold and some plated .
There is a definite lower sound on most the gold rings than any brass stuff I tested, the pulltabs are mostly higher sounding also, the exception are larger mens gold rings that sound like one of the pulltabs, the lower conductive tab.
I'm starting to get the hang of the sov a little better each time I use it.
Today I went back to a place I was the last three days and scanned the exact same ground with a cz70Pro and the gt sov over again. I slowed way down with my search technique with the sov and I pulled out 16 coins from the same ground I went over both with the gt sov and cz earlier. Also got a silver dime I missed and I guess a lot of others missed. Its a real worked over place I was in. I choose this place because it has a very heavy accumilation of iron and also has the modern accumilation of replentishment pulltabs and foul. Makes for a good place to possibly find missed stuff.
I also was using the smaller 7-1/4 inch tornado coil instead of the 10 inch coil , trying to see if I could get better separation in all the iron, I still hit the silver dime around 7 to 8 inches deep among the iron which is small piece of wire looking stuff partially bent in a half circle , looks kind of like wire from those small short fences placed around flowers or plants people don't want to run over with their lawn mowers.
Since I have about 25 hrs practice on the gt now I have learned to be able to set it up for a very good much clearer sound then when I first used it. Also learned how to set up the notch to knock out both types of pulltabs and still find every thing above and below including nickels. When the coil passes over a notched out item it will give a high treshold sound after the null, so I know I Passed over a pulltab or something with the same type of conductivity if I want to do a check out dig. Of course the sov makes those threshold tone changes over stuff that is nulled either iron or something being discriminated . This is the first detector I have been able to accomplish knocking out both types of pulltabs and still find nickels with a solid signal tone. Every coin I found today was a solid two way clear tone. I even get a slightly lower clad tone then the silver highest tone.
Getting a little easier to recognize differences.
Any other solid tones I dug for a look see , was stuff I did not have notched or discriminated out with some lower tones like a small brass key I found. A large aluminum foil( cigarette pack) came in loud but registered the low tone foil hit. I knew it was big junk from the sound and size area the hit made.
This Sov has so many different ways of responding to targets along with the tone variations it's a detector unlike anything I ever used. ( going to be using it exclusively because of this ) to learn its language. I would not be so fussy if I where just beach combing with it though. Just dig every thing and listen for the deep stuff.
