Re (There will be a lot of people who won't fork out for the 12 inch,)

I could be in this Group

Re( but probably will for a bigger one, or a 10 inch.)

I find very very small gold with the standard coil, What could be the expected benefit with the NF 10 inch or the X Coil 10 Inch other than weight eg faster to find the gold in the dirt after you have dug it out of the hole. ( me, it takes ages for very small gold) Or with a more sensitive smaller coil a faster swing. Or smaller size to get between rocks/bushes ( not a major consideration for myself)

I was one of the enthusiastic ones but i guess i was delusional to think it might cost as much as what coils used to cost.  Like around $500.  But it is like Steve said, if we all say we will pay, they are watching.  I am going to bank on research finding me more gold vs new equipment.  It has worked so far and the SDC has found more than my Z, and it is $5000 dollars cheaper!  Explain that one ?.  Here, I’ll explain it.  I’m not a pro nor do it for a living.  I’m a hobbyist and go out on weekends until the ground is frozen, then I sit and wait.  If I calculate out what that costs me per weekend (in unfrozen ground since at that point depth does not matter), it would be $50 a weekend for a detecting season (May-Oct, if i go every weekend).  That is a gram of gold every weekend for one year to pay for it.  If I can find a gram of gold every weekend as a hobbyist, i would be pretty stoked.

I’ve done a fair bit of time on the ZSearch coils off and on throughout the year and in my environs X signal is a real bugbear, being able to calibrate that out completely relative to electronics temp is really important in the ground I work in.

The next big bugbear is Saturation, a lot of care has gone into the new NF coil to get both these things right, the ZSearch 12R saturates less than the GPZ14, no small feat considering a smaller coil is more prone to saturation signal than a larger one.  

X calibration aside IMHO there are four clear positives to the new Nuggetfinder coil, minimal bump and knock sensitivity, way less Saturation Signal, 300 grams lighter and lastly its definitely much more sensitive over standard. All of theses things add up to my finding gold in known test patch locations and not all of it has been sub point 0.2 gm.

One of the early prototype’s, the final version is even better electronically than that pictured.

What is the actual measured diameter of the final production NF 12", JP?

Looks like the first of the GPZ Nugget Finder Z Coils are being delivered:

https://www.prospectingaustralia.com.au/forum/viewtopic.php?pid=587396#p587396

Weight with lower shaft 1070grams vs Minelab stock coil with lower shaft 1408grams.

I'm sure many performance comparisons will follow......

The 2 most asked for requests for a brand new GPZ successor were lighter weight and smaller coils. Here it is, for 1/7th the cost of a new GPZ. With the addition that this coil is reported to get equal or better sensitivity to most common nugget weights.

It's like buying a new machine for only $1000. This is a better improvement over the GPZ than the 5000 was over the 4500 IMO (assuming it matches the X Coil performance).

I am pretty surprised at the lack of excitement here. Has anyone in the US preordered one or do any dealers here even plan on carrying them? I would have been first in line if I didn't already have a 12" coil. Are people just waiting for a smaller one mostly?

More is oft times less, so what might work in one ground type will not necessarily work in another. To achieve a universal coil that is acceptable “everywhere” first the coil needs to meet a very high standard dictated by Minelab itself, X balance being the main one and minimal Saturation signal being a high-order second. There’s no point in having a specific coil design that only works in homogeneous quiet ground types, Minelab have always had a winning formula based on detector design that is always aimed at working in Australia’s highly mineralised ground types, as history has shown if they can get it to work well here it will work well in less challenging areas too!

The ZSearch 12R X balances extremely well (It’s been remarked “better than the GPZ14”), the 12R also saturates less than the standard GPZ14, both of these things provide an advantage straight out of the crate in the vast majority of detecting areas in Australia, especially Victoria. Because of the construction methods used the Zsearch 12R is also a LOT lighter than the GPZ14, the main bugbear of a lot of detector users around the world, both in people choosing ‘NOT’ to buy and people opting out.

Lastly I can attest to a big improvement in sensitivity over standard and also less EMI and less Salt/Conductive signal, so the combination of less weight, less EMI, less Salt, less Saturation signal and correct electronic design tolerances all add up to a VERY obvious improvement in even the worst ground types.

If the first NF GPZ coil does not meet your needs then don’t buy, I for one applaud the honesty they’ve shown on their website which IMHO is highly downplayed based on my own personal experiences. Nuggetfinder have plans for more models in the future and when that happens I’m sure we’ll see more innovation as time goes on. Every coil bar 2 in our allocated stock have pre-sold with customers picking up their coils today. I now have customers buying into GPZ because of the weight reduction alone.

Because I helped develop this product and because I sell this product I’m happy to sit on the side lines and let others experiences filter through. All I can say is my own observance, especially going over ground that has seen me frequent these areas hundreds of times over the past nearly 5 years, I am once again pinging nuggets during one-on-one training sessions, no small feat I can assure you.

Nuggetfinder have sold out on their first manufacturing run, already that number exceeds other figures quoted on this forum. Now it’s time to let things settle and let the early adopters have a chance to go out and play.

If you read the first trial report from the new owner of the coil then it would appear the NF 12" does have more sensitivity. 2 x specs found in situ could not be picked up with the stock coil https://www.prospectingaustralia.com.au/forum/viewtopic.php?pid=587426#p587426
