That being said, I understand that typical Pulse machines are very sensitive to gold, but also very sensitive to iron.

How well does the ATX pulse machine discriminate, and how well does it reject iron, while maintaining sensitivity to gold, and especially small gold?

The ATX is very sensitive to gold (and tweaked to do so). It really shines in areas where there is known gold to exist, and will get substantially better depth then a VLF gold detector. It also handles extremely high mineralized areas and hot rocks where a lot of other detectors struggle. It will pick up tiny gold and larger gold. It is a very sensitive detector, and even more so when run in non-motion mode. It can be ground balanced and will also scan a preferred frequency to use should there be EMI issues in an area.

Now, all PI detectors are very sensitive to iron, and you really can't eliminate it. The ATX does have an iron ID, giving a low grunt on iron. This is accurate to about 6" on coin sized targets with the 10" x 12' COIL, deeper on larger sized targets and less on smaller targets. A PI does not discriminate at all like a VLF detector.

So, where are a PI's strengths? Looking for gold in gold bearing areas. Keep in mind that you will be digging up 22 shells, bullets and tiny nails. However, if the coil goes over a tiny flake of gold or larger nugget, you will get a signal. I have done very well with gold rings hunting areas which had been hunted mostly with VLF detectors, with the bonus that usually most of the junk has also been removed by those hunters.

Here's a link to some ATX Videos -

Thanks for the videos John. Just one more question.

The ADX has discrimination settings, but the videos I have seen so far place more emphasis on using the iron grunt to discriminate, rather than the discriminate settings themselves.

So, how does the discrimination settings work? Can you not just use the disc settings to knock out small iron?

The discrimination will change the tone break (low nto high or high to low) and will eventually remove some targets, but at the cost of losing extreme depth. Both the Sea Hunter, Infinium and other models also share this same characteristic. The only time I have ever read where someone added a small amount of discrimination was to knock out some heavy mineralization under extreme conditions. Bearkat put together a nice video to show how advancing the discrimination on the ATX affects various types of tagets.

Thanks John. Still trying to get a grip on the high/low--low/high thing.N/T
