Things I've noticed...

Well-known member
I've had my V3 going on 2yrs and noticed that every gold ring Ive found has always sounded very solid and repeatable, and in analyze mode it even looked good. Out of all the thousands of pulltabs I've dug, very few ever really sound that solid and repeatable except for the new square tabs (23 range) and the old sqaure tabs. The rings I've found ranged from 17 to 47.
I'm wondering if any of you guys have found any gold rings (not chains) that didnt sound really well (bouncing, not repeating ect.), and not because of masking.
Thanks,
Aaron
 
I have had the same experience as you Aaron....exactly. I dig most all the tabs except for the "bouncy" ones in the mid 30's. I really make sure to get a dead on pinpoint, with all of those , before walking away though. If I am running the standard or bigger loop, in a large area, and patches of tab/ring targets are close-ish, I just dig them all here. (Larry gives some good advice with spending too much time "deciding" whether to dig or not to dig here...."Dig it already!")

Have to admit, it's been a long long time since I've found a ring that's numbers strayed too far from center. (Unless I dug with a less than good PP.)
 
I agree!...Maybe it doesnt work in some kinds of soil but here it works pretty well....on what is what.
 
Rings just never seem to be too deep. This has to help with the solid ID's. They do seem to be solid hits for me.
 
Nope... numbers were everywhere. The last gold ring was a 16k white gold ring and the vdi's where from 30-40. I dug it only so that I would not see it again. It was no more than 3" down. It however has huge setting for a 5 karat stone that must have caused all sorts of halo. The 10k mens band I found was rock solid at around 4" with trash all around and in the hole.

Gotta dig them all.....:drinking: That is if you dont want to miss any.
 
If your numbers were between 30-40, that is not bad...I wouldnt consider it "everywhere". Now if your numbers are 15-20 off... thats different.
Regarding the "halo" on the gold ring I doubt it, as gold does not oxidize.
Thanks.
 
That situation is right on...... band rings should be a solid ID and any ring with a stone mounting should bounce the VDI around because of the odd angles of the mount and prongs..... at least that was my findings on tests.
 
Now with all that said, I don't believe their is anyone out there who knows they have a ring before they get it out of the hole.
 
True that Gold and silver does not oxidize but you will still have a halo on older Gold and silver that has been in the ground under the right conditions. The oxide halo will be in the dirt around the ring from galvanic action of two unlike metals in a dielectric, (water or better yet, salt water).


Here is a good course in helping you understand how halos develop. http://www.pdhonline.org/courses/s118/s118.htm

The other dissimilar metal other than your target are the metallic minerals in the ground.
 
And the halo debate continues. :devil::devil:
 
Good to hear from you Jack. I don't have a halo either.
 
Thanks Larry.
Ok...I can agree to that, under the right conditions and it would have to be OLD gold.
That said...I think its safe to say under most conditions, at least in most parks, its unlikely to find gold jewelry with the halo effect.
At least not in my (low min) area.
 
You've nailed it. Simple, round targets produce a smooth return signal and a pretty stable VDI, while the more intricate (read: the more the possible paths for eddy currents!) the target the more harmonics are in the return signal, and thus more bounching VDIs and/or gritzy sound. I found a very heavy silver ring once that bounced the VDI all over the place. Thought it had to be can slaw - and don't know why I dug it, but I did. It was huge with many elaborate features.
 
You're about 99 percent right. I have had a couple, though, when I just knew it HAD to be a ring. One was a small (about a size 5 or 6) 18k ring with a small emerald. It read a solid 17 VDI and didn't bounce at all, and it sounded so SMOOTH. I just KNEW it was a gold ring. (Course, I've had that feeling a few other times before digging up one of those darn painted pull tabs....LOL)
