cz-70 air test

[eek]

Can someone explain to me why I get no signal when doing an air test on a gold necklace with my cz-70?
I am new at this detecting thing and am doing a lot of reading and as much detecting as possible, but
I am sure that I will have a lot of questions... A lot of questions have already been answered just by reading
the cz-forum..

Thanks,

Eek...necklaces are tough for most detectors. Where you testing it in discrim mode or all metal ? In reading about necklaces on the forums, apparently the dectector sees only 1 of the links in the chain. If it is a very fine or thin gold chain, it may not pick it up at all, even when you brush the chain against the coil. Most necklaces/chains found are either thicker chains with bigger clasps on them that the detector picked up, or the chain had a pendant on it. Or, the chain was all balled up, but that may not help either.

I would not worry too much about those thin chains...you have a great detector in the CZ-70. Learn it and use it and it will find you lots of great stuff. Best thing you can do starting off with that machine is run it with sensitivity at 1 or 2 to start, and discrim at 0 and LISTEN to the targets. Make sure you ground balance spot on, and dig all repeatable mid and high tones, and investigate/dig all the deep tone bounces ( from low to high, low/mid, etc.). Use your pin point to size up the shallow targets and if you get a big pin point foot print, it's probably a big piece of can slaw or iron.

Have fun with that machine...it's a good one.

Thanks JC, I had a felling that something like that was the reason....I have heard that chains were hard to find, but did not know about an air test..
You helped a lot and that means one more question is down and waiting for the next one to pop up..

Thanks and God Bless,

I have a CZ70 also and the 5" coil picks up a thin gold chain on the ground better than it picks it up in the air. Try not to pump up the sensitivity as you will get a reflection because the CZ-70 is a hot machine. Try putting the chain on the ground and see what happens with the sensitivity at 4-6 and accept everything and use in ID mode. You should be able to get a couple inches out of it on the chain.

If you are hunting where you think you might find gold chains like at a swimming hole, you should be hunting in Auto mode and when you pick up a signal switch back to ID mode to help ID the target. And then pinpoint and you should be able to distinguish a chain by the length of the target, (unless it's all bunched up) then you would pick it up anyway. When I am hunting in swimming areas that's what I do, and it gives you a little more chance of not missing those small thin gold chains.

Hope that helps a little.
