NF Z Coils Empty NF Z Coils

Post  PeterInSa on Sat Aug 29, 2020 11:53 am

Am disappointed that a 10 Inch Coil is not the first Z Coil introduced by NF, I am happy with the standard Coil even though its heavy and the new NF 12 inch even though its lighter is reported to have similar depth and sensitivity to the standard coil, so it looks like a longer wait for the 10inch or smaller for me.

However will still be very interested in an in depth comparison.

Have used a 24" Elliptical on a 4500 so that could be a future interest also.

Hmm interesting, could be worth a go. Any info as to price? I'm curious to hear if it is noisier than the standard or not. How are NF handling the plug issue? Lots of Questions. Question

They have the chip installed so no issues of modding the Z... Should mean no more blown up Z's... Plug straight in...

Perer, one would hope that NF produce something that is 'considerably ' better and not just as good as. Weight yes, but that is why after market coils are made, to improve the depth, sensitivity, noise ect. Other wise why buy one?

Two people are searching for big deep nuggets over tough ground and each has the same model tecta and same size & type coils. The only difference being that one is an after-market light weight coil. and the other is a bloody heavy original and gives you the irrates after an hour or so.

Who is likely to find a deep mellow weak large target signal first? The bloke with the heavy coil swinging low and slow with nice smooth sweeps or the bloke with the light weight coil skimming over the ground a tad quickly and maybe somewhat erratically.....Just coz a coil is new and light weight does not mean that it will deliver better results in the field.?

If two people are swinging the same detector and coil looking for deep colours the deciding factors are experience and success history. An idiot swinging 'low and slow' is still an idiot.

Adrian, even an inexperienced detectorist, swinging over ground a tad quickly & or maybe somewhat more erratically, has better chance at hearing a faint target signal, when knowing his coil is performing/achieving 25% better depth advantage over a variety of in ground targets, over that of another blokes coil of similar in size/shape, producing 25% less depth advantage.
BTW, there can be more than one reason as to why someone all of a sudden can be seen swinging a coil somewhat a tad quicker & a bit more erratically over ground, & it comes down to (& as Reg has said) either lack of experience, or struck down by the sudden calling of nature. Laughing

I understand the NF coil has similar depth and sensitivity as the standard coil.... but its not as heavy.

Thanks Imael, It may be woth the wait not having to change the plug. If it works well of course. I usually try to run in normal if at all possible so it would want to be at least as quiet as the standard for me to get one. Then there is price , depth etc. I guess we will just have to wait for info. Basketball

I agree with the last sentence.Laughing

I have located thousands upon thousands of targets by using the low and slow technique as compared to when I detected at a rapid pace. using either vlf or pi tectas. All gold nuggs that I found, both large (large for me is over 10g) and small have been soft mellow signals from surface to maybe 18 or so inches while going slow. So if I ever get back out into the gold fields I will continue to be an idiot.Smile

When I said "an idiot swinging low and slow", I was referring to the fact that some people do not know what a deep subtle signal sounds like, only recognising sharp obvious signals, but hey, if you want to class yourself as an idiot adrian, who am I to argue. You know best. (as usual)

Gents, lets not stray far from the main topic here.
Adrian, In no way am I trying to ridicule what you say, for that would be going against all logic/common sense. Going low & slow for the better hearing of faint on surface or in ground deep targets, always has been & is the right way to go.
What I were referring to (after reading your comments) was that, would not a complete armature when first shown & or placed in an area highly likely to contain gold within reach, have far better chance of locating gold even if swinging a little faster or more erratically over that same section of ground, than an experienced detectorist going low/slow, but with far less detection coil depth.
So its not just about experience & going low/slow, but actual depth advantage between one similar in size/shape coil to another, over a specific type/section of ground.
Have we not all heard the saying a top of the line "detector" suited for a specific task, makes even an armature look good, when placed over potentially promising looking ground & in the hands of an experienced detectorist, look even better. That's it end of story.  
PeterInSA I have no doubt that Nugget Finder have put a lot of work into this new 12 or 13 inch design coil for the GPZ & just by the offerings the coil comes with, are a major bonus/plus, but to me, its not about the slight/better weight factor, as much as it is all about coil performance. Keep in mind I talk of "for me only"  (not for the majority of GPZ users), will find it hard to cough up $12 or $1400 dollars for a coil that basically, is close to that in size & performs similar to that of the standard GPZ 14X13. But again, that's only me, but for the ones who have held off for the sake (& rightly so) of not wanting to take a chance in making a very costly mistake by way of blowing up ones detector, I say good on yas. The time has come when one can do all that now, in a more safe & appropriate manner.
As for the true working characteristics of Nugget Finders newly designed GPZ coil, going by Nugget Finders past history & the first release of a number of new size/type coils to be made, leaves me with little doubt, that the newly made Nugget Finder GPZ coil, will or should be up there in performance with the best of them. Again, time will tell.

Cheers gents, Kon.

NF Z Coils Empty Low and slow

Post  Reg Wilson on Wed Sep 02, 2020 3:30 pm

The old 'low and slow' doctrine does apply to certain brands of detectors, and sweeping at even a moderate speed these machines can fail to respond to certain targets, especially small or faint ones. I always found this bothersome when detecting (prospecting rather than fossicking) as I like to cover as much ground as possible in a given time. Taking a day to cover an area the size of a tennis court is just not my style.
The beauty of the detector that I now use is that it has the fastest and sharpest target response of any detector I have ever used. Light weight, nicely balanced, and performs well with all coil sizes. Now I am not forced to detect like a tortoise on Prozac, but can cover more ground accurately and quickly than ever before.
Low and slow is now old hat.

I like my Old Hat, fits well and does the job.
 I no longer have  need for a GPZ or the Qed  so I will never exp their performance; would have been nice to give them a try out but as young (28 when dead) Ned said "Such is Life"
I do have tectas that require a fast sweep that  give excellent results on small shallow or large deep targets but I guess low and slow suits my current physicality.

Post  xmas tree on Wed Sep 02, 2020 9:19 pm

If it's not larger than the Z coil, and doesn't go any deeper than it, what's the point in buying it? Seems to me you're paying for something no better than the coil you've got. I'll be waiting for a 20" plus coil to increase my chances.

Every body is talking about weight and the new coil will be lighter. If you set up your hipstick right then there is no weight, the hipstick that i made transfers all the weight to my normal jeans belt.

The weight is still there regardless of where you may transfer it. Being trussed up like a Christmas turkey and having to be burdened further with a 'cripple' stick is not my idea of comfortable detecting. There is no excuse for heavy detectors. They do not need to be built this way. It is just expedience on the part of the manufacturer.

Hi Tg, I use the Z Hipstick and the Occy strap from the Z Harness to the shaft, the standard coil gets heavy in the pm.

Have seen a Mt Gambier friends setup that has an AL piece of metal riveted to the back of his harness going over his shoulder and about 120mm to the front with an Occy strap at the end, to his Z shaft this to take the weight of the coil. I should have tried it out, but it looked so agricultural.

The Coil weight hits my lower back muscles, if transferred to the belt/waist that may help.

Any chance of a photo of your Hipstick.

Peter

A well balanced detector, even a hefty one takes a lot of strain off the wrist, back and shoulders.
First thing I do with any detector is balance it to the coil being used.

Post  Kon61gold on Thu Sep 03, 2020 1:19 pm

For the majority of GPZ user's, the use of the bungee cord coupled to the GPZ's swing arm, is essential & not an option, for I highly doubt anyone using the standard 14x13 GPZ coil on the 7000 without the use of a bungee cord, could get away without any fatigue problems over long periods of swing time.
The New Nugget Finder GPZ coil states that it weighs in at 1000 grams (excluding lower shaft), whereas the standard Minelab GPZ coil weighs in at a hefty 1350gm +/- a gram excluding lower shaft. This in-itself is a bonus in weight factor alone, when swinging the coil for prolonged periods of time.
Joe, (less any other unexpected further delays) nothing more has been said from NF about the release date of their new 12 inch GPZ coil. So I take it we can expect them to be released sometime this month of September 2020.

Joe, you are 38 years old FFS. When I was your age I too could swing bloody great heavy prototype detectors with coils that made the stem bend. We'll see how many rooted joints you have when you get to my age.
