Gold Catcher

Still, 1 star for SDC and GPZ is a bit odd. But it shows the intended trend across machines.

Here is the complete comparison including GPZ. Sorry for the blurred picture.

Perhaps selling some expensive dowsing rods to raise some cash for the real thing 🤑

An expensive armada....😉

It will also be interesting to make this comparison with small gold when the gold is actually burried in the ground. The ground processing I always found to be a real strenght of the GPZ. But no doubt the 6000 has alot to offer. Can't wait to get mine!!

Yes good point. I was refering to small gold nuggets and flakes. But consitency is key since even faster time decay if porous

Could be invisible with smoothing on. With smoothing off in HY/N I have picked up stuff so small that you can barely see it with your eye. So, I remain curious how much better the 14dd ultimately will be on tiny gold. So much depends on the settings on how you run the GPZ and conditions. Also, not many people pay attention to the really tiny gold with a GPZ. I do.

Thanks for the report, Lunk. That's really great. That's 2.2 lb lighter than the GPZ with same coil size. That's really not bad. I guess the 14 DD will be better at small shallow gold and the Super-D will trump in depth.

Completely agree with that. Strict coil control is always your friend!

Hi Gold Hound. Of course you can use monoloops anywhere with good success, including Australia. I was just merely suggesting that when directly compared to the Super-D GPZ 14 a similar or bigger size monoloop might struggle a bit in highly mineralized ground, hence giving the GPZ a depth advantage for example in areas with "old soil", like in Au. It even says it in the 6000 draft manual that top performance of the 17 inch can be expected in less mineralized grounds. This could be a planned strategy to not eat into GPZ territory for conditions where the GPZ14 inch shines. But I am sure we will get to the bottom of this once the 6000 is released. So much still (healthy) speculation.

That's something I am most interested in. How does the SDC/ 8 compare with the 6000 / 11? I am a SDC lover (like you :)) and will put this to a hard test. Regardless of outcome, SDC will remain always in my fleet! The 14DD I find interesting for it's reported EMI/conductivity cancelling. This will be a great comparison with the GPZ14 in respective tough grounds.

We all shall see when we start testing the 6000. The GPZ14 is an excellent and balanced coil and handles saturation remarkably well. I was just echoing what appears to be common knowledge about pros/cons of mono loops in general. Bruce Candy's ML write up gives an excellent perspective on that in case you want to have a look. But as Northeast said, perhaps there is some secret sauce that is coming with the 6000 that will change the game 🙂

Do you have experience with the Coiltek 15 on the SDC? I like the 8 because it's just perfect for small gold with the MPF timings. Just wondering how this would translate to a larger mono loop. And then of course there is the 6000 11 in /17 in mono loop performance anticipation...

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"

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.

I think the GPZ screen could be more robust. It easily scratches. Also, the backlight is not sufficient. It's hard to see the display at times, especially with cover on. This would be two points I would find worthwhile improving.

I can highly recommend the Iridium Sat Phone. It has reasonable monthly plans and let you call anywhere in the world, from anywhere. Works even from deep canyons. https://www.iridium.com/products/iridium-extreme/

Another head scratcher: how a preliminary draft manual got leaked for the world to see

Interesting. Looks like the 11 inch mono is the preferred to go coil with best sensitivity. The 14DD is more for troubleshooting situations and is stated to be (only) the second choice. Clearly very different to the GPZ, and more reaching into SDC territory from this preliminary look.

Good advice and I never would. Nothing beats my GM (5 in) when I need to discriminate for shallow small gold. But, Gerry's recent praise of the Nox (6 in) as a superior small gold sniffer makes me wonder if I am behind the curve with the GM. I am not a relic hunter but perhaps the next Nox generation would be the perfect choice to complete my "gold" fleet. 🤔

Looks like a nearly perfect machine thus far. Have not seen anything yet that I don't like.

I use the Bose Quiet QC20 when it's windy, works great! JP tipped me off on that when I saw them in one of his posted pics.

Nice going GoldTree. Persistence and adherence to detector rules (i.e. always check holes) pays off. Dismissing targets because of sounds has never paid off for me, and clearly would not have paid off for you in that situation. 😁

Can't wait to be wireless. Let's see if a booster would be needed at all. Would be great to get away without any cables.

Thanks. If that's the only requirement then lets hope they will make some nice rugged ones made for prospecting.
