Quote Goldchaser: "If people have sold their 45 or 5k to get one and coils don't come out for a while you might actually be at a disadvantage, on larger deep gold, some are smart not selling their Gpx's, just don't see it beating a Gpx with 18-20-25" coil with a 14" coil, be nice if Minelab would say what's gonna be available  coils etc. Hope it does punch deeper then a Gpx with a 25 mono but I just cant see it...."

Great point Goldchaser!

Somebody is going to have to tell us soon: Will the Gpz 14" dd coil beat the Gpx 20" mono coil?

Up here in Yankland I can't ever use a coil bigger than 18". Most places I have found bigger gold have terrible EMI and I can't use anything larger than a 12" round mono. Even with that the afternoons become a headache. I guess my question will be how it handles the EMI with that 14" coil compared to a GPX with same size coil. And, to be honest I'm more hopeful that it will be able to punch 20% (or more) deeper on the 1-5 gram nuggets. For me that's what would really pay off. Most of my patches have a lot of nuggets in that size range but very few if any half ounce plus. If I could be digging 2 grammars at 12-18" regularly my poke would fill up quickly.

Just my desires based off the prevailing conditions where I'm at. – AA

Gpz 7000 with 14" D coil or Gpx 4500-5000 with 20" mono coil Empty What does 40% deeper mean?

My expectation is that when ML say 40% deeper (* yadda, yadda, yadda), they mean on the same target. So while a 18-20-25" coil may punch deeper in raw inches; we know that 'Jonathan' found a 12 gram'er at 17" (I assume with the 14") ..... so the question you have to ask is: would a GPX with a 18-20-25" coil find that target?  

Hmmm..... maybe, maybe not. The issue being that the target is getting too small for a GPX with a 18-20-25" coil at that depth. You would be more likely to find it with the 18" rather than the 25".

The other consideration is that, as we know there are (exponentially) more smaller nuggets than larger nuggets. Hmmm (again).

Yeah slim geoff its gonna have some tricks up its sleeve,wouldn't be surprised if the 14" matches or betters a 18" mono but the 25" if you have a spot for it (big deep gold) well that would be a feat. Geoff might be on the right track also,say 10-20gr bits it might punch deep on?
Can't wait to read reports on it,i dont understand all the secret squirrel business,their taking deposits,why not let people know if other coils etc will be available......

Cant see a 14 inch dd beating a large mono, if you use a large 18m inch mono on a gpx you would beat the 7000 on bigger gold, (you would think), but the 7000 apparantly has been getting .1 bits during testing, so its sensitive on small bits.

That's the point guys.We have no sound clue/evidence as to what the new detector is capable of.Let me say this though,if it can find the same size/type multigramers at greater depth,over similar ground conditions,than that of the 5000 could do with a similar size coil,what chance have the larger solid multi-ounce slugs got of not being detectable at greater depths also?

Just to clarify the 14" is not a DD coil and could not be compared as such.Specs say its a 14"D.

I've picked up a 12 gram nugget at 14" with the 5000 and a 8" commander mono so if you can't afford the best the gpx 4500 and the gpx 5000 will still get you the gold. You just need the right settings for the area your working.

Easy Uncle Bob the jury's still out on the best yet, as far as I know its still (arguably) the 5000 at this point, lets wait a while and see what happens, you know what I mean eh, its a young bull and old bull thing eh! Wink

DD? But the gpz7000 uses a Super-D, not a DD...

I just had a look at mine and it is certainly a 14" D for discrimination. jocolor jocolor jocolor jocolor

The specs already say that there's no discrimination. It's a new type of coil, neither DD or mono.

Here's the second page, 5000 on the left, 7000 on the right, for discrimination it says .'all metal' which means no discriminator.

Just to muddy the picture even more (sorry guys), a dealer mentioned a few days ago that the leaked specs comparison was not all correct. The story was the document was in the middle of being edited/compiled when the leak occurred - so some of the info is correct and some is not

Of course what is and isn't correct was not elaborated clown

Now doesn't that open the door for even more rampant speculation Laughing
