We all know how great the E-Trac is on hitting silver, but I wanted to check the responses on my own gold jewelry. I found that gold rings will respond everywhere from 02 thru 40 in the CO scale. I was a bit suprised to see the womens (adult, not child) rings reading consistantly down from 02 - 06 range.

The real shocker was the bracelet. I tested my wife 14K tennis bracelet and got ZERO reading. Rubbing it on the coil didn't produce any response. It got worse though. I got out my PI machine and it couldnt see it either. This isnt a tiny bracelet. It weighes more than any of the rings I have found, but nothing would read it.

I have always known that chains and such were harder to find becuase of the links, but I never thought one this size would be impossible.

I challenge everyone to test thier own or thier wife/GF/SO chains and post your findings.

Well..........my wife detected my Girlfriends' bracelet and that was an eye opener :rofl:
No, seriously, I'll have to try that.

What are your settings? Program.
 
i tryed it on a 10kt and 14kt and my e-trac didnt sound off, i used a open srceen on the e-trac. heres the pictures of the two that it did not sound off on.
 
Roll the bracelets into separate , clumpy piles ( not spread out ) , place them on the dirt outside your house and then see what happens when you roll your coil over it . .
Turn your discrimination down too .

tried it. zero discrimination, open, balled, nothing mattered.
 
ive tried this a while back and had the same results.....but i didnt attempt trying it in two-tone ferrous. maybe that will work? i wrote it off as one of the few sacrifices of owning a minelab. it wouldnt read a gold earing stud either.
 
Thanks for your results Jason . I don't have an ET but I would have thought it would have made a difference .I have an SE but I can't test either gold or silver chains as I have sold them all ( got those with my Tesoros ) .
 
when i first got my etrac i tested a medium weight gold chain and it didnt sound off at all whoops my partner said well i bought it as gold honest whoops i thought it was fake although it was stamped so i didnt put it back in my jewellery box and guess what i have lost it and i am not happy i mentioned it to a guy on one of the rallies and he did say it would have sounded off had it been in the soil i think we have to do a few more tests when the weather improves i will take a gold ring and bracelet attached to some strong dental floss and bury them see if i can get signals interested to know if anyone else has a gold necklace to try as i no longer have one whoops

I have to agree with Dr. Dirt,... even the lowest priced Tesoro Compadre would hit on those gold samples. I have seen what an E-Trac will do on deep coins and they are good detectors for that kind of searching, There are lots of high end detectors out there that will fail to detect small gold, but most Tesoros will detect them with ease. The thing is......with gold chains, the detector can only pick up the individual links of the chain, and a detector has to be sensitive and have a discriminate circuit set low enough into the iron range to be able to detect that small link.

I just found a 14K chain with my ET, but....it had a nice pendant on it! The chain gives no reading at all! Not in the dirt, in air, balled up, whatever. Gold rings sound off fine.
 
Two tone ferrous won't make any difference in the E-TRAC's ability to detect an object. It only instructs the E-TRAC to provide an audio tone based on the target's ferrous properties instead of it's conductive properties. The amount of discrimination, Sensitivity setting and the "material" surrounding the target are three big factors in why some targets are tough to find. Many folks leave the detector in Auto Sensitivity, which might not be maximizing the potential for a given situation. Especially in air tests where the transmit signal is not being reflected by ground matrix or adjacent targets. And I mention the "material" surrounding the target because the E-TRAC does not offer a ground balance feature. Instead, it automatically neutralizes the effects of the ground, based on software interpretation of the soil matrix. If you're doing air-tests, you have no soil matrix. And if you're using Auto Sensitivity on those tests, don't expect the same results as if the target was buried. JMHO HH Randy

Not so. The Compadre doesn't hit on chains any better than any others I have tested. The only reason it does fair is when using the small 5" coil. With the 7.5 DD coil it doesn't see a thing.
 
I sold the gold (chains included) I found with my Tesoros to buy my Etrac. Haven't found any gold chains with the Etrac yet. I know most people buy an Etrac because of the reputation it has for sniffing out deep old coins. For what it costs, it ought to be able to find gold chains as well. Anyone have a smaller coil to test and compare results with? Is this thread giving anyone buyers remorse?

Hey Southwind

The Compadre never came with a 7.5 DD coil....only a 5.75 concentric or the 7 inch concentric on the older Compadre.

Not in the least! Every machine has its strengths and drawbacks. The operating frequency has a lot to do with its detecting abilities. The E-Trac is a silver killer, so naturally gold would be it's weakness (theoretically). It just seamed strange, I have found tiny bits of foil and aluminum, sometimes at several inches depth, but it wouldnt pick up this chain. The real shocker was my pulse induction wouldnt see it either, and it just came back from having Mr. Bill tweek it.
 
Out detecting with some friends with e tracs and one found a gold ring and it certainly had a sound,
One theory was the higher the gold count the stronger the sound.
We all thought the ring was 18K because of the look.
Does anyone know if the karat count in gold makes a difference in the strength of the sound?
 
Chains are the hardest thing for any detector to detect.

As for the karat count.....the amount of alloy gets greater, the lower you go on the karat scale. So, if you have a 10 karat ring...it would be 14 parts alloy and 10 parts gold. So it would depend on how you set your detector to react on what you are looking for.

I do not think that a change in karat would dramatically change the signal strength by any degree, given that they are equal in size and weight. Gold is not like most coins that are generally strictly regulated for content. Gold karat can change at the very least by manufacture and by country that it was produced or refined in. It should be exact but quite often it is not. Sometimes foreign gold color is way off....either because the karat is different or because of the alloy that its mixed with. Sooooo, it would be hard for a detector to detect minor differences in gold content as generally speaking not set up for that task at hand.
