Have a gander at this link, could be my premonition coming true.

Well put clodhopper, My sentiments exactly. Nothing ventured, Nothing gained. Hanging to get over there and get amongst it.

Dunno why minelab hasnt put up more info on website, more videos.

Well guys,

Had my first 3.5 hours on the new toy last evening.

Hit an old patch of mine that gave up lots of nuggets from 0.3 to 2.5 grams, but all solid pieces, no species. Flogged it with the 4000, 4500 and 5000 with coils up to 20 inch mono and varying timings.

I was close to high voltage power lines but was able to run the sensitivity at 18 out of 20, with no audio smoothing at all. Threshold was a little warbly, but targets still pulled you up, a bit like the SDC. Ground type difficult, high yield.

Ended up with 2 bits that totalled only 0.35 grams, both about 0.17, smooth waterworn. One at a carefully measured 7 inches ( took a tape measure and dug slowly ), and the other at 6 inches. Couldn't believe the depth for such tiny bits ! It's a friggin SDC on steroids !  Oh, and 5 lead shotgun pellets !

The 5000 had got anything of significance at this spot, but will try more of my flogged patches over the coming days and report in.

The detector is well balanced with a bungy and hipstick, no sore arm after 3.5 hours. I like it, but is it better than a 5000 with bigger coils, not sure yet ! Is it worth the money, too early to tell !
I'm tipping that it will be a weapon with a 20 inch coil though !

The trouble with the Ararat area is 99% of the gold around here is smooth, waterworn and solid, and hence I have been able to get it with the 4000 - 5000. Trying to find somewhere around here that is more suited to the GPZ may be difficult !

The 7000 may re-open the goldfields, but no where near as dramatically as ML suggest. It will be more suitable in some areas. It will ping the smaller worthwhile bits at depth that the 5000's have missed, and maybe larger bits at depth with the rumoured 20 inch coil.

Rick

G'day Rick,
Thanks for your efforts mate much appreciated.
Rick did you try to run in other settings like extra deep/diff or normal ?

I'm guessing the ground is hot and in the past with the 5000 you were using fine gold or enhance
Looking forward to more of you tests

Regards snapper

Yeah, tried normal as well, ground too noisy even after backing off the gain a bit.
Didn't try extra deep as this area does not hold any deep very large nuggets !
Used to use the 5000 in fine gold through here, and did very well with it.
3 hours doing another patch this arvo for 7 lead pellets ! 5000 has cleaned it out !
Tomorrow is another day, and I will go and try a farm I have access to.
You tube clip below from yesterday.
Cheers,
Rick

Here is my question. do you think the 7000 will out perform the 5000 on west australian ground
seems to me the 7000 is just a souped up 2300. hmmmmm
$10,700 is a lot for a souped up 2300

Well ??? are we looking at a 2300 with some extra grunt.
I haven't seen anything to put a new spark into my interest of spend the money.

Considering one is a PI and the more expensive a VLF... I'm thinking the breakthrough is more to do with the coil design in the newer machines to run quieter?

Starting to wonder what would happen if they made a 14" coil for the SDC?

Coil Swamping thats what

2.4 grammer found today, at a farm area that I have hammered with the 5000 with coils up to 20 inch round mono. 10 inches deep. Difficult ground type, general, gain at 15, no audio smoothing.
Also found another 2 little bits for a total of 0.6 grams.

It is clear from the 20 hours I've had on it so far, that it will find the little bits deeper than ever before, but I think it is constrained by the 13x14 coil.

So far this machine is definitely not living up to the hype, but only time will tell how good it really is ??

If your saying the GPZ 7000 is a VLF, then I think your wrong.

Good stuff Rick keep it coming mate, so far it seems only JP is finding heaps and big stuff I guess Bruce Candy has given him a few tips !

Good luck
Snapper

good onya Rick, cheers for the vid mate.
with what vid's are available so far I cannot see any 7000 owners being disappointed in there new detector apart from the price, it seems to be finding the gold for sure but the claim off opening up your old flogged patches does not seem to be coming true. I suppose the real question would be 40% deeper hmmmm not sure but very early stages still.
it looks to be more user friendly being not hooked up to battery's and speakers but the extra weight will wear you down quicker, the extra swinging arm looks like it would take a few hours getting used to but once you got it would become 2nd nature.
I'm guessing the 7000 vs 5000 would be similar to the 5000 vs 4500, not a lot between them and it does come down to the operator and what ground ya walking on and off course coils being used.
I hope they get stocked up soon, I'd like to hire 1 for a bang over a weekend, but I'm sure I'll have to book well in advance.

Nice one Rick
Geez you gotta be happy with that paddock mate, she's been kind to ya
Thanks for posting your vid mate and good luck out there

Pete

Jase

I'm with you

I would like to get one for a weekend and have a crack

Pete

A good place to test this would be the Hangover Patch
Had species and nuggets but we know there is bigger gold heading down to the main track and over the ridge

Need to give that a bash

Peaky

Geez ! Araratgold I take my hat off to you, how did you hear that signal. I have rerun your video a couple of times and the initial signal wouldn't have stopped me I'm sorry to say.(Sorry for me that is) My better half is always on my back to get a hearing aid, maybe she is right ! (I know she won't read this so I'm safe saying that unless my BIL spills the beans).
Thanks for the report, and nice find Rick.

Woteva

Would I do that when I'm in the same boat ???

Very interesting posts and Video, thanks Rick

Isn't it a hybrid; it is not pure PI nor pure continuous wave (VLF) but has attributes of both.

VLF - Sine Wave (analogue signal that switches negative/positive at zero volts)
ZVT - Square Wave (digital signal that switches negative/positive at zero volts)
PI - Square Wave (digital signal that switches at negative/positive voltages)

No switching in a VLF, they are constant send receive, this is why theyu cant handle heavy ground, they get swamped as there is no switching to allow the target decay and reduce ground noise like a PI.

Now I'm totally confused.
if VLF, PI & ZVT all have negative/postive then what makes the 7000 special ???? OR is it just the new coil design ??
And something that has been forgotten is, there's no salt timings. What good is that.
I've also read that it may not be good in WA highly mineralized ground.
So I'm relying on the experts, so far, I'm not impressed. JMO.
