Nuggetfinder Coils Release Dates For The 6000 & 7000?

[Gold Ryder]

Put the 11" Minelab back on after running the NF 12x7" for the last couple of months,  to run over some nugget patches I found with the NF.  Right away I wished I had the NF back on.  It is so smooth and stable compared the the stock 11" .   I found nothing else in the patches.  And hunted around the rest of the day with it.  No gold.  A few pieces of small iron trash and a couple birdshot is all.  One thing I noticed on the stock coil is the lead shot is definitely louder on the 12x7 and the little wire and iron is ALOT louder on the stock coil 11".   I moved settings on the stock coil all day trying to get it tuned in and settle down a little since my ears have gotten so used to the 12x7".  Finally just settled in to the noise all the while wishing I had the NF on.   After today I dont see the stock coil going back on much and am definitely looking forward to NFs release of the bigger version.

Sometimes I wonder if some of these reports of the 11" being unstable are due to slightly faulty 11" coils, my first one was like that, I hated it, it put me off using the 6000, then I had it replaced under warranty and it was like I had a new detector.  Yes my old 11" worked, it found gold and did what it was meant to but the detector was much more unstable and noisy than my new 11".

The stock 11" is a junk coil. I've seen 2 cut open now and the shielding is poor (40-65 ohms per inch and an entire width measurement of only 50 ohms on one in particular). The bunch windings had bulges in them both, some almost a cm wide. This explains the noise and the altered sensitivity in sectional areas of the the coil. A chip on one had a re-soldered joint where the pcb etching was destroyed. Amazed it still worked TBH.....

If the first 2 are anything to go by, it seems likely that the stock coils were made by the lowest bidder in Malaysia. Both of these 2 coils would have been rejected by any QC team in Australia, Japan, USA or EU.

Thankfully we have the Coiltek and NF coils now.....I haven't used either of the ML coils since owning a 12x7 and a 10x5. Just need a smaller DD coil and the NF 16x10 to complete the arsenal.

Glad you brought it up  ?

@Coiltek  anything in the testing phase that you can divulge?

I keep reading terrible reports about the 11" coils and feel lucky that I got a good one.  It is just crazy sensitive to tiny pieces and also larger targets at depth.  Granted, there are fine cracks in the coil ears and one at the cable insertion point but performance wise it is faultless.   It will get returned under warranty but I'm not in a hurry, and certainly not before W.A.  

And I'm still on my original coil cover and I scrub quite a lot  ?‍♂️

I've been told the Same, it works but mine is still noisy and has altered sensitivity spots. Compared to the Coiltek and NF offerings, its poor.

From the NF web site: 

ABS Housing

Polycarbonate Shaft Mounts

Polycarbonate Triple Sealed Cable Entry Point

External Gore Breather

CoreCell Foam

Litz Wire

Water Sealed to IP67 Standard

2 Year Warranty

Minelab Approved 

CoreCell is the best and most expensive foam coring that I know of having bought this product many times myself I know how much it costs...its used in the boating and aircraft industries on high end builds...there are cheaper coring materials you could use but they choose to use the best. I asked the guy from Coiltek (Trevor I think) on this site what they specifically use for coring on their coils and he would not give me a direct answer. There is no substitute for quality.

That's interesting about the 11" and not a surprise, many arguments were based upon people loving and struggling with that coil.  I don't think anyone was wrong it was their coils causing the discrepancy.  It's truly sad their quality has gone to these levels.  The 11" is a good coil when it works, it's super sensitive but it seems you can't trust it.  The day JW's died was a shock, he was just detecting away near me and his detector went erratic like EMI, this was certainly not unusual at the time as the EMI fix didn't exist then, so he turned it off to do another of the many factory resets we had to do at the time to keep it stable, and then it came up with a coil error, and never worked again.  Mine was just erratic from the start and I hated my 6000 until I bought a Coiltek coil and worked out my 11" was faulty, then had my 11" replaced and was happy with the 11" after that.

Putting manufacturing into the hands of the lowest bidder isn't the best way to get a good product.

NF and Coiltek appear to have done a great job on their 6000 coils, and NF in particular judging by stricks comment above have made an outstanding coil when it comes to construction quality.  It's interesting they dropped the warranty from 3 years down to 2 years on their GPX 6000 coils though.  the GPX 5000 coils were all 3 years, not sure what the Z-search has, I never intended to use the warranty on mine as I gave it the snip a week after getting it, the sacrificial lamb.

In this case we are fortunate Minelab allowed aftermarket coils so early on with the 6000, as it took many years for the 7000 to get its first aftermarket coils.  Maybe Minelab knew their coils were bad, if people move off them onto aftermarket there is less chance they'd need to warranty their 11" as they won't use it.

I'm looking forward to the Sadie size, I may even buy the 16x10" too so I have a good range of sizes and I think that's a great size for doing some patch hunting on the 6000 and really patch hunting and tiny gold are the detectors strongest points so may as well take advantage of that.

me too,,,

just had a noisy 11"coil replaced and a dry solder joint fixed in a 6000  from Minelab Adelaide ,, and its a much quieter more stable beast now ,,,  the New coil looks totally diiferant when you take off the skid plate
