The Attributes of a Good Jewelry Hunting Machine

[MarkCZ]

My brother is going to let me correct myself it looks like, he is digging up his results and firing off emails.
Here is a screen shot of a spread sheet he did of some gold jewelry test. (looks like he hasn't added the Tejon to it yet)

It took me a few minutes to put it together in my mine. I figure come warmer weather he will add the Tejon to it.

Also, we know that air test (or just laying the object on the ground) isn't conclusive, but if it don't like gold on the ground, its not going to like it any better in the ground.

Small gold and detectors
F75Ltd using the little elliptical I could only get both open and closed small gold in the boost processor with a disc setting of 8 and sensitivity at 85.
Gold open and closed, I used a small loop ear ring and I found it made a difference when it was open or closed. So when it is open it is like an ear ring that we would find. When it is closed it is like a small finger ring we would find in the field. See picture
The Tejon with the larger stock 9x8 coil
Small closed gold = just on the high side of foil disc, good signal
Small open gold = right on the line of iron, weak signal

Small coil 5.75
Small closed gold = just the high side of foil disc, good signal, same as big coil
Small open gold = just shy of half way between iron & foil, this is just a little better than the big coil, still a weak signal

In the above he is talking about the little gold earring, I thought he had told me that he couldn't get the F75 to hit on it at all with it openl??
Oh, well I humbly stand corrected

I guess to keep things on track for jewelry testing my detectors, the testing between the F75Ltd, the 1270, and the 1266x was done at one time using different test items than when I done the Tejon. So I can't really say which is best.

So just putting a little gut feel which would be better for jewelry, I would go with the Tejon and the 9x8 coil, second would be the F75Ltd with the little 6.5 elliptical. I can say for sure if you go with the F75 and the 6.6 elliptical you will not get a lot of depth.

Now for test gardens, I have put every detector I have owned on my brother Mark's test garden and done a few test coins in my own yard. From everything I can see my brother Mark is right, the detectors we have tested most will not do very well on newly buried coins. Now I did say most because the Tejon seems to be out there buy its self. A few months back I planted a couple of coins in at 7" and I tried to get the F75 to hit on them with all my coils, 11DD, 5"DD and the 6.5 elliptical, none would hit. Got the Tejon out and bam it hit both with both coils, but now this is where things get a little strange. I took both detectors back out just a few days ago to test over the same coins, the F75 still nothing, but now the Tejon is just barely picking them up. Can't explain that, but I still like both my detectors.

Okay, we started off with,
[size=large]The Attributes of a Good Jewelry Hunting Machine[/size]

For me and just thinking jewelry and not versatility, it would need,

To be a bit higher frequency.
It wouldn't need visual ID at all! (Audio target ID would be okay, but not necessary)
It would need to have better than average discrimination control.
A good choice of coil options for it.
Light weight is a plus.

And to go along with all that the operator would need patience!!!!! because the gold jewelry is any good signal between foil and zinc pennies and that's lot of trash.

With the above I'm thinking of land hunting because that's what I do.

Now for beach hunting and salt water hunting you would need something entirely different???

Maybe the "Tejon" don't care about ground matrix or halo.

If I were going to buy one, which is better on all jewelry, Vaquero or Tejon? Also on deep silver?

I'm sure there are machines with a better ability at low conductors (certain two filter machines, all the beach pulse machines, etc...). But if you're talking about turf and land, I can hardly think that having a machine "better at low conductors" is going to increase your odds of getting a gold ring, verses most typical coin machines. For example, the Explorer is known for being a good machine on deep silver, and is not known for getting teensie dainty things (like earing studs, or whispy chains, etc...). But you've got to figure, the parks are LOADED with low conductor signals, because if you're talking older inner city parks, they've often been mined for their silver and coins, and people have cherry-picked passing surface stuff, low conductors, etc... So ANY machine can go into a lot of parks, and you can dig low conductors till your arms fall off. So .... simply turn down the disc, and have a ball, even on power-house machines like the CZ6, explorer, XLT, and so forth.

But if you meant on the beach, it would depend on if you need to be able to knock out iron.

I like everyones comments.. I like a smaller coil/ I think it might be a little more sensitive to smaller gold items....KEN
