phrunt Posted September 12, 2023 Share Posted September 12, 2023 I figured I'd contact Nugget Finder to see what's going on with the other GPX 6000 coils, I quite like my Xceed 12x7" so intend to buy the 8x6" also, I think it'd be a weapon on the 6000. So, to save anyone else wasting Rohan's time replying to endless emails about when the coils will be available, I thought I'd post it here. This was his reply. Hi Simon Releasing the 16x10 is our priority at this stage, I don’t expect to have the 8x6 ready for sale until sometime in 2024. I understand these delays may be frustrating and I appreciate your patience. Regards Rohan Perhaps that means the 16x10" may be released this year, but the little guy is a fair while off yet, a shame as spring/summer (now) is when I do most of my detecting so I'll miss out this season. I'll stick to my GPZ and 8" X-Coil for the most powerful small coil detector for now. Link to comment Share on other sites More sharing options...

Has there been any field testing results of the 16x10, in particular for larger/deeper gold vs the stock ML 11 inch mono coil or the NF 12x7 or the stock ML 17x13 mono? Some have said that the stock ML 17x13 mono was not that much deeper than the stock ML 11 inch mono, is that true? Is the GPX 6000 one of those machines that has limited depth improvements when using larger coils similar to the SDC 2300? Link to comment Share on other sites More sharing options...

I agree to both these assumptions but with a caveat, my findings are based on my age (jockey) and my ground (course). Can there be a defining answer or just opinions? My experience tells me no. eg. The ML19 (horse) on the GPZ7000 is referred as a dog coil by many, I found it a producer at depth over the ML14 which was the only other coil at that time.

JP was testing out the 16x10 what was likely a year ago now putting up gold find promo stuff but even that fizzled out. He appeared to like it and at the time I got the impression it was near ready for sale. I don’t think the readiness of the coil design is the problem as much as perhaps Rohan has more important things in life to deal with than making coils, it’s a much smaller business than Coiltek so he can’t be filled in for by staff the same. I believe the 6000 is limited with coil size to depth benefits like the SDC from experimental coils made for it. Minelab want you to buy a 7000 for deep gold. The 6000 has plenty of coil choice now anyway, if only the 7000 has as big of an approved range. The 6000 needs more DD coils than anything else.

Dutchman4 Posted January 4 Share Posted January 4 The 6000 needs more DD coils than anything else. I tried the ML 14 DD and there was no improvement on my collection of hot rocks so it appears the 6K does not appear to benefit much from a DD coil with the exception of EMI rejection.

phrunt Posted January 4 Author Share Posted January 4 Yes DD’s do little for hot rocks on the 6000, but are much better for EMI and maintain small gold sensitivity. Link to comment Share on other sites More sharing options...

For my gold fields and ground the NF 12x7 mono is plenty sensitive and is stable/quiet. I read that PI machines benefit with handling hot rocks and mineralized ground better when a DD coil is used but the 6K appears to not exhibit these chacteristics so that means I have no need for a DD coil. The only question that remains (and has not been answered) is if I can get "significantly" better depth on larger gold with a larger mono coil on the 6K. If the answer is yes then I was hoping it could be the NF 16x10 since the 12x7 is such a great all around coil. Link to comment Share on other sites More sharing options...

phrunt Posted January 4 Author Share Posted January 4 The stock 17x13 will be the deepest larger target coil available, the 16x10 is highly unlikely to be deeper I think, unless it’s smaller gold. Size gives it away, the NF is likely to use the same windings type Minelab used and they did on their 12x7, the idea of 16x10 to me would be similar performance to the 11” with more ground coverage and possibly more stable as the 12x7 is more stable than the 11”, could be less EMI due to smaller size though.

Chet Posted January 4 Share Posted January 4 GPX 6000 test coils I know of some areas that have produced some large nuggets. So in pursuit of large gold I have experimented with winding some test coils and did some air testing. Results are with my poor hearing and varying EMI conditions. But the measurements work for my comparison testing. On bad EMI days the larger coils are very noisy. A 20 inch 12 AWG Litz coil might be the next one to test. Meanwhile I am experimenting with some large GPZ 7000 coils.
