mcjtom Posted January 11, 2022 Share Posted January 11, 2022 This has been said many times, but there is nothing like seeing it. I can’t tell the difference between those particular two, in any orientation, either by sound or ID (on Vanquish 440). Are there any tricks of the trade to increase the chance of differentiating the right-size gold ring from a modern beer can pull tab? 6 Link to comment Share on other sites More sharing options...
Skull diver Posted January 11, 2022 Share Posted January 11, 2022 From my point of view, even at a similar if not equal VDI number, those finds are usually not "friends". I mean rarely You can find it togheter in the same spot, unless on the dry where things can be a mess. Usually on the wet and the surf a good division is done by the water motion so You can expect the pull tab far and higher from the low tide line and conversely the ring lower down from there to...Anywhere.... I repeat, usually...So dig it all still is a good advice, trust me... You can see also today a bottlecap reject on the D2 and not a Pulltab reject....Same VDI results by shape and size...Sorry... By the way, editing this reply I forgot to write the number 7, which again means nothing to trust to, but usually on the ctx this is most of the time a pulltab shown at 12.07... On the Vanquish I think must be an higher value due to the different VDI scale. 7 2 Link to comment Share on other sites More sharing options...
Popular Post PimentoUK Posted January 11, 2022 Popular Post Share Posted January 11, 2022 I understand (from careful data collection a US guy did many years ago) that rings like that, with a 'heavy' part, tend to sink in the ground with the heavy part downwards. This means they are more likely to be 'on edge' , whereas 'staytabs' have no real weight bias, and will be randomly oriented in the ground. So, focusing on the 'ring on edge' may possibly help increase your odds, from very slim to slim. It depends if you're going to repeatedly visit a particular park or not. If you intentionally leave 50% of the ringpulls because they don't sound 'finger-ringy', they are still there to bother you next visit, and the next. 9 1 Link to comment Share on other sites More sharing options...

And so has the following, but worth repeating: any action taken to avoid digging a signal will result in some good targets being left in the ground. Coins are the most consistent target because their size, shape, weight, and composition are carefully controlled during manufacture.

Mike_Hillis Posted January 13, 2022 Share Posted January 13, 2022 Nice Ring. I'd say you are on the first step of understanding what a gold jewelry detector feature set requires. If you can't see a difference in phase shift, then you have to rely on audio, both disc mode and all metal mode. Does the 440 allow you to hear the audio difference between a tab and gold ring? Does your all metal mode allow you to hear the difference between a tab and a gold ring? Does coil height over the target matter? If you can't see the difference then you have to rely on audio responses to give you clues. HH Mike 6 Link to comment Share on other sites More sharing options...

I will never forget when I hunted behind a guy with a Nox when they 1st came out and before I got mine. And I was using my DF. He was leaving an "X" in the sand behind him. Which I dug just to see what they were. 95% was trash. I got 2 junk rings and a $700 SS watch. I've learned that many of these "discriminated trash" signals can be a cellphone or even a rusty junk chain with a gold ring on it. Ya never know , till ya know. 8 Link to comment Share on other sites More sharing options...
Popular Post Steve Herschbach Posted January 13, 2022 Popular Post Share Posted January 13, 2022 Frankly it’s just playing the odds, and therefore a gamble passing aluminum range targets if you want gold. You can weed out irregular aluminum to some degree by digging only targets that return a single, strong target id number, which translates into audio tells if you hunt by ear. One reason I like full tones as it gives far more audio differentiation as compared to 3 or 5 tones, which lumps way too many targets into one audio response. But you will also pass on most chains, irregular shaped pendants, and especially broken rings, if you only dig those “round” targets. Reality is there are both gold targets and aluminum targets that will respond at almost every target id number across the entire range. It’s governed by size, not the metal. Way more to it than that, I just wanted to offer one simple trick, not write a book. See below for that. It is interesting because just like any gambling, a degree of gambler psychology creeps in. Those that aggressively pass targets almost always are very confident in their ability to leave lots of aluminum in the ground, while they also are quite sure they are missing minimal gold. The problem is simple. You can’t know what you are missing. Some extremely high value women's gem set rings give really lousy signals due to large prongs or multiple prongs, and some oddball creative designs. You only have to pass on the wrong ring once, to pass on a find of a lifetime. That all said, even though it uses DFX as an example, this is the best jewelry cherry picking book I’ve ever read personally, and why I still own a DFX, which I only use for jewelry detecting. But the methods apply to all capable brands and models, and I highly recommend anyone into jewelry detecting have a copy. Plus, here is the Mike Hillis book list, with which I whole-heartedly agree. DFX Gold Methods by Clive Clynick You can find all these great books, and many more, on Clive’s Website.

stevejhgla Posted January 14, 2022 Share Posted January 14, 2022 Other detectorist look at me like I'm crazy when I tell them that with the equinox aluminum sounds weak and sometimes scratchy. Hope this helps. 1 Link to comment Share on other sites More sharing options...

Still, some (successful) jewelry detectorists give them a run for their money in their dislike of discrimination. I have seen gold nuggets, and even .22 shell casings, read ferrous sitting in plain site on the very worst of ground. That will ruin you forever on discrimination. I’ve dug literally ounces of gold investigations other peoples abandoned dig holes. It’s not always they tossed trash back in the hole - they gave up on nuggets, large ones, because the machine said they were no good! The detector sees everything, target plus ground, and if ground ferrous is high enough, it will override the low conductive non-ferrous signal, flipping them to ferrous. Same thing happens with VLFs in high magnetite content beaches. The more filtering employed, the worse the problem gets. If it’s any consolation, it turns aluminum signals into ferrous signals also. 5 4 Link to comment Share on other sites More sharing options...
