Aftermarket for GPZ

Thanks Wally, yep that was a nice slug, there's not many places that I've been detecting that you can dig with a spade though.

In the first video, once the top soil is removed it looks like broken quartz.

cheers dave

It's no wonder these blokes like these coils, check out this open spoke type variety and the size gold and the depth etc.



cheers dave

Picture shows a bit of a range of coils they are making and how they look beside the GPZ 14 and 19 coils. They are really liking the 16" open spoke coil over there, and getting good results.



cheers dave

Looking good Dave !

What size is the big one next to the GPZ19, looks about 25 inches ?

Hoping they might be ready for WA next year ?

Cheers,
Rick

G'day Rick

I think they mentioned 22" but it looks bigger than that, like you say.

WA next year will be perfect I reckon, fingers X ay

cheers dave

Here is a video of the 25" aftermarket coil getting a small piece deep down, when a big coil can get these it's not going to miss big ones.



cheers dave

They have a good variety of coils all working well, this is the 15" solid coil on the GPZ7000, it's getting cold over there now -2c with some snow on the ground.

15" coil


cheers dave

Fingers crossed, those coils work as good here, as what they seem to work there Dave. Any one coil that can show me, an average of 10%+ depth increase, on a range size/type nuggets, over that of the GPZ 14x13, I'd be more than interested in, as would many other GPZ 7000 user.

Cheers Kon.

Dave do know when and if these coils will land in the OZ market?
and what price range they might be?

Marty

Thanks Kon, and yes I'm hoping for the exact same thing, they do look impressive where they are using them.

G,day Martin

I do know that the manufacture is sending me two coils, they are on there way right now from Russia, a 22" round open spoke type, like in one of the videos, and a 16x15 solid, also in one of the videos, I'll be giving them a work out at Stuart Town, Hillend and Ophir type areas for a start when they arrive, I will let people know and if they want to see the coils in action they can.

Price and time frame for sale, I don't know that yet.

cheers dave

Hi Dave.
It will be great if these coils are priced to sell and can handle extreme iron mineral ground. The one in that vid appeared to have a fairly low profile which hopefully translates into a lighter weight.
Looked odd to see a nug come out of black soil, I assume it was mineral black sand??

G'day Adrian

The one I used in WA was 18" and (low profile) and weighed about the same as the GPZ14" Minelab coil, it handled the ironstone ground very well, I hope the rest of them do as well.

And yes it does look strange to us seeing gold come out of that black ground, the ground and videos and the coil manufacture are all in Russia, and having never been there I have no idea about the ground type over there.

Price, I don't know at this stage.

cheers dave

The 16x15 coil is the manufactures favorite coil they refer to it as their flagship coil.  This video show the coil on some of there more minrealized ground, they start of in setting high yield, normal rx13 and the buried test nugget can barely be heard.  Setting changed to extra deep normal rx13 and the test nugget can be clearly heard.  This coil and (2 others) is on its way to Australia for me to test on our Aussie ground.



cheers dave

Hey Dave
When will you be at Stuart Town ?

As soon as the coils arrive mate, if your interested I'll be sure to let you know when.

cheers dave

Looking forward to hear the results of your testing, over our ground conditions Dave.

Cheers Kon.

I could be there at the 19th or the 23rd of Nov
otherwise I'd have to put in for extra time of work

M.

Also at 0'53sec on the vid the operator is pumping the coil like a GPX is that a normal GB with these coils ?

With the GPZ7000 using the semi auto ground balance, this is the normal way even with the ML 14 or 19, just like a GPX5000 running in tracking mode, pump the coil up and down.

Once you have a good ferrite balance using the green button (sideways sweeps) then using semi auto GB it's just up and down like before. Semi auto locks in the ferrite.

Also I'll let you know when the coils arrive and we can maybe plan something from there. I don't know how long the take to get from Russia to Australia and then to me, but I guess it's a couple of weeks or more.

cheers dave

ok Dave lock in some dates for in Dec when you think the coils might be here give or take a week
As I need to put in my days of work in advance
You know same sh!t different day LOL

Dave, I think you might have meant High Yield / Normal for their first setting, not difficult / Normal.  They are both ground type settings and can't be run at the same time?  I am sure it was just a typo but might be confusing for some.

All the best.

Yes echidna, your right, and that is what I meant, thanks for that.

cheers dave

Made a big difference going into extra deep, quietened the ground markedly whilst still in normal. High yield normal is great if the ground is not too noisy, but that was clearly very noisy ground. I often use extra deep, and its surprising just how small a target it can detect. It's a real " sleeper " mode !

Cheers,
Rick

I reckon your right Rick, those settings must have been put there for a reason, I seem to have been stuck mainly on High Yield/Difficult, and sometimes High Yield/Normal, with good results when the ground permitted, I also have used the salt mode and found gold in extremely bad ground.

I am keen to give these coils a good run, the only one I have used is the original prototype 18" and it was great.

cheers dave

Sounded a bit ordinary to me for a 7000.
The ground did not look oxidised and I reckon lacked iron??
The nug looked about 0.8g or there abouts.....My TDI sounds of on a 0.88g slug a bit like that at approx 4 inches with a 6 inch CoilTek mono in my back yard. Ground balances at close to 8 on a range of 10 on the TDI.
That hole did not look more than 4 inches deep to me. although difficult to say when looking at a flat screen image.

Just some thoughts.

This is not sand this is black earth. Fertile layer. This is probably the former field (arable land).

Yes that is what it looks like. Hope the coils work in tough ground.
I guess it should though because it is the tecta cctry that does the signal processing and not so much the coil....On the other hand some Coils aint coils Sol

A very large specie with plenty of gold in it, another video of what the fellas in Russia are finding with these new generation coils for the GPZ7000



The specie cleaned up


cheers dave

Did you get the new coils yet?
