Hare and tortoise springs to mind.

I took the Coiltek 14"x9" for a swing this afternoon. I'm not going to rush out and buy one.

I visited a large pending "E" lease not too far from home. Nice looking ground with lots of ugly hollow quartz scattered about and a few quartz blows standing a metre or so above the ground. Unfortunately it takes more than a lot a quartz with a scattering of ironstone. I never raised a nugget and apart from hotrocks I had to go over some previously worked ground to get any digable target at all.

I started out with the new GPX6000 fitted with the new 11" mono coil and I have to say it was performing very nicely. Sure it chattered away more than I like but I guess the more sensitive the detectors get the more noise we're going to get back. There were lots of hotrocks, the heavy black shiny ones, and the 6000 found them all but it was manageable by just kicking the worst of them out of the way.

After half an hour or so I swapped to the Coiltek.



The first problem was that he gave me the coil without the bolt and washers. The Coiltek doesn't have a threaded mounting flange, you need a nut so I had to find one on the back of the truck. It was a steel nylock nut but I don't think it made any difference.

The first thing I noticed was the weight. It feels heavier than the 14" DD even though its not supposed to be. It seemed to be quieter over the small hotrocks but it honked loudly on the larger ones. Perhaps a little less chatty overall but not enough to have me rushing out to buy one, in fact I never will and there are two reasons for that. The first is the weight. It's just more than I want to swing about these times. The second and perhaps most important is the lack of sensitivity on the outer perimeter of the coil. I had an 11" Detech and a 12"x8" NF on the GPX4500 and I sold both for that reason. A lot of my gold is detected by the edge of the coil and any coil with poor performance on the outer edge is no good to me.

I'm going to return this coil and try the 12"x8" NF next. I don't intend to buy one but my friend offered them for me to try so I may as well give it a go.

Did you not have any plastic you could push a tread though?

I could have used a zip tie as I've done before but the steel nut worked well and it took me all of about a minuite to find one on the traybody. The bolt was only plastic so it was not capable of forming a thread.

This morning I have the 12"x8" NF so I'll get out for a small swing this afternoon but I'll go where I know I'll get small gold.

Have never been a fan of playing around with different coils. Each to their own, but feel it is a waste of time and money.
Have seen more than once prospectors trialing a different coil and they find a piece of gold and are hooked. Asked them did they test the supplied coil to see if it picked up the signal?
On several occasions we dropped the gold back into the hole and covered it up then refitted original coil and swung that over the target.
Yes, the signal boomed in. (And yes re-burying a target is NOT a true test)
Some will say a lot of gold is missed if you don't experiment, but then again if you missed it you will never know.
Trudged around with my SD2100 for 10 years swinging the 18"Mono, that machine talked to me after I became very familiar with it. Had prospectors say that it was impossible to swing a mono over ground we were on. They even took over my SD and it proved to them you could with correct set up.
Along came the 4500 and majority of time the 11" Commander Mono did the job. Initial search on new ground was with a 20" NF mono.
Now the 7000 with the supplied 14" has found gold down to 0.08g, not likely going to fit any other coil.
With this machine there are many who say it is too heavy. You see them with the bungee connected to stem just above the coil or just below the control box. Positioned so it hangs naturally in swinging position you can actually let it go and nudge it back and forward. Swing for hours without fatigue.
Down off my soapbox, and reiterate, each for their own.

Yes Peter you're right but we all like new toys

I charged the GoPro and shot out to the lease this morning. I filmed everything but so far the videos have failed to open. I'll try fiddling around with them tonight.

The short of the story is that I wouldn't buy the 14"x9" Coiltek or the 12"x8" NF. In my opinion neither is as good as the original 11" mono.

 

[geof_junk]

I found testing on nuggets buried, is not 100% as you know the target is there. Most nuggets you find are not hit dead centre when you first get a responds.

 

[Moneybox]

I've not been able to revive the two videos that I took today so I'll try to replicate them tomorrow.



The most difficult part might be finding a couple of nuggets to test before they are disturbed.



I walked about twenty metres from the van and got four targets with the GPX6000 on the standard 11" mono and marked them target 1-4. Then I changed to the 12"x8" NF coil and swung over the same spots.

The first, a weaker signal than the original coil was a 0.13g nugget at just over 50mm down, quite a disappointing result. The second was a 0.26g nugget at just over 100mm down but barely registered with the NF and was a good clear signal on the Minelab 11" mono. The third and forth targets were rust near the surface which gave a good crisp signal.

I continued to swing the NF for a few more minutes. The next target was a 3mm shotgun pellet so at that point I decided it was time to head home. I got another faint target heading back to the van, it was a small hotrock about 10mm across and 25mm down. I took that as a sign to turn the detector off.

I thought I had about 20 minutes of video on the GoPro but I can't open the files so I'll try again tomorrow if John doesn't repossess his coil

 

[Hippyty79]

I got both z search’s, I agree the original is still the best, just wish they were built better.
I run the 17 a couple trips back it seems to cancel the small gold out when the golds out of the ground, had to switch back to find the 0.4

Is this regarding Gold Fever? I think we all have some level of qualifications in this field

Some have varying degrees of the fever & the cure.

7000mg of gpZ couple litres of water and a walk normally cures me

Moneybox,
thank you for your report on the GPX6000 with testing on those two small sub-gram nuggets, as it sounds like the factory stock ML GPX 11” coil >>has better depth performance than<< the NF 12x7 Xceed coil. I have both coils but I have not tested one against the other, that is why I am so interested in your report.
~But I have heard from others that the NF 12x7 Xceed coil >>is quieter running with less chatter<< than the factory stock ML GPX 11” coil.

~Yes that is the exact same two complaints I have heard from others that the Coiltek 14x9 Goldhawk coil has ‘poor (low) sensitivity’ around the outer edge especially on the front nose “and” also it is ‘too heavy’.

Deano, I was a little harsh on the little NF coil yesterday. Pitted up against the 11" mono it was a disappointment however today we gave it another crack. The result was the same however it's not the fault of the NF. I'm swinging a brand new GPX6000 that was sent to me by Minelab as a warranty replacement. This machine coupled to the standard 11" coil is dynamite.

Today I did the same as yesterday. I started out with the 11" coil, picked up all the rust I could with a magnet and then marked the remaining seven targets. Then we swept over them with the SDC2300. All the surface targets were rust and a couple of deeper ones were not detectable with the SDC. Next I swapped from the 11" mono to the NF 12"x8". It detected all targets however the deep ones were not as clear as the original coil but I dug them. I'm waiting for videos to download but the audio is not good. We had a nasty breeze and a continual flow of roadtrains and we were detecting just 100m off the highway.

If you've got a decent GPX6000 I'm quite convinced that there's no advantage in swinging the aftermarket coils unless you need the narrow profile. The original coil is better at depth and an awful lot easier to pinpoint with. I can often just pick a little nugget out of the ground with the first scoop of dirt leaving the pick on my belt. If you were to compare the Coiltek and NF coils with my original GPX6000 and 11" coil than the result would no doubt be different. Both these coils run quietly and perform well but my new Minelab coil is better. This is the first time in two years that I've be able to have a stable threshold. The 14" DD performed perfectly too on our recent trip to Leonora but I thought it may have been the region we were in.

I took the borrowed coil off and continued to detect with the Minelab 11" mono while Mrs M chained with the SDC2300. I marked out about ten targets and called her to swing over them with the SDC. Almost all the gold targets, seven in total, were undetectable with the SDC2300 running flatout with threshold on three. She scraped enough off some of them to create a signal and dug them out. They were 0.04g, 0.06g, 0.08g and 0.12g. The two that she dug for, one down to about 50mm and one down to about 75mm, were still undetectable with the SDC. I came back with the 6000 that sounded off with a very clear signal and dug a 0.33g at about 150mm and a 0.20g that was at least 130mm down.



The reason why the SDC2300 can't detect these nuggets is because this ground is just 3km from town right on the highway, used to have multi-ounce nuggets and has been done to death for the last 40 years.

This new GPX6000 is better than anything that has been there before. We only walked over a patch of about 50m x 6m of a 72HA lease. Yesterday it took me about 5 min to find the first gold target and today was the same. I need to get into that patch with the loader and dryblower but there are only so many hours in a day

Looking forward to the vids Phil but wonder if the coils are designed to fail, great machines the coils do the the job, but are flimsy.
Been I’m business for most of my life repeatable business is good, much like a buying a new car they’re hoping to make a buck on servicing,
Coils are disposable, no repairs
Makes you wonder how many coil sales were made before the z search.
Look how long it took for nf legally to bring out a gpZ coil.
Then look how quick the 6000 coils came out.
I think now they are generating enough revenue from treasure machines they let their guard down.
A sale is a sale and a dollar saved is a dollar earned

Your a legend that my problem with my fridge slide, explain, I was going to tack weld a rod between levers

Ps
Sandra a crackup. Love it

There is one advantage of the Nf coil. It will last longer than the minelab 11" , my only gripe about the 11" coil, is I'm worried everytime I use it, it will clap out on me.
