Minelab GPX 6000 Full Reveal In February 2021?

Also ask about 17” mono coil availability for US.

I wonder how the 17 mono will perform in mineralized grounds. Most gold bearing grounds are mineralized, so probably not much of a competitor with the GPZ14. Perhaps more intended for African deserts?

GPX 17 Mono
The GPX 17 Mono coil is the top choice for covering large areas of ground quickly and
efficiently. It is the top performer when searching for large deep nuggets in less mineralised
ground.
Like all monoloop coils, the GPX 17 Mono is susceptible to noise in conductive ground or when
there are high levels of EMI.

As Aureous noted above, the only thing we've seen so far regarding Geo-Sense PI is that “it rapidly suppresses unwanted signals via three overlapping feedback systems for superfast detection of even the tiniest gold pieces.” Exactly what mechanisms these feedback systems employ may never be revealed by Minelab for proprietary reasons, just like they've never revealed the exact proportions of the Multi-IQ weighted frequencies used in the Equinox. Regardless, the fact that the GeoSense PI tech will allow us to detect difficult environments once thought undetectable, as indicated below, is all I need to know about it, as it will effectively open up new ground for prospecting. Happy days are here again! ?

Is Quartzsite crowded now or not so bad?

The big RV show is over, so it's not too bad now.

Opposite. Bigger coils are better in mineralized ground (both for PI and the GPZ). Worse in salt (conductive) grounds.

I'm guessing something along the lines of auto adjustment of sensitivity, ground tracking, and EMI cancellation? I'm curious how static the timings are. In other words, does Normal go "a little more Normal here, a little less Normal there" as you move along too? Or is such a thing possible?

Thank you.  Maybe I'll make the drive on Saturday.

Since prices have been released now can someone ask in Quartzsite if we know what the MSRP on the 17" coil will be and when we might expect US availability?

That seems to be the speculative consensus, as unwanted signals include EMI and ground noise, both localized and variable.

I was referring to the fact that it is a monoloop. Only in low mineralized ground a big mono will have an edge in depth. In mineralized soil, they don't perform that well as the DD or Super-D.

"The magnetic strength to cause noticeable saturation to a sensitive metal detector depends on the magnetic chemical. Most of the superparamagnetic particles found in the goldfields require intense fields to cause saturation whereas, ironically, some more benign mineralised soils saturate more easily, and thus may cause worse spurious signals than the highly mineralised goldfields. Double-D coils are excellent for suppressing the effects of near-surface saturation, whereas mono-loops are poor at this. Thus, this saturation can most easily be noticed when using a mono-loop coil as one “pumps” the coil up and down, causing varying field strength in the soil"
