Coiltek Goldhawk Is Impressive On My Gpx-6000

[phrunt]

The way I see it is the 6000 is sensitive enough to small gold with the 11" coil, you really don't need more small gold sensitivity than the 11" coil gives.  The GPZ was not sensitive enough with small gold which is why it greatly benefited from small coils turning it into an entirely different detector.

With the 6000 being already great on the small gold with the 11" there are two reasons I wanted a smaller coil for it, obviously the key one being to get the coil into places an 11" coil is just too big and awkward and the other one is giving the 6000 some more depth on the smaller bits as that's where it's a bit lacking at the moment compared to the GPZ and small coil. 

If by putting a 10x5" or another brands smaller coil on it I can get some extra depth on those smaller bits I'll be happy.  This would normally be the case the smaller the coil the more depth on small gold so I'm hoping that holds true also for the 6000. 

What I do know already is the 17" coil on the 6000 is nowhere near as deep on small gold as the 11" and this is from actual in field finds that JW and I did side by side comparison on, this bodes well for the 10x5" being deeper than the 11" on the really small bits.

GR Guy.  Do you have the info to put a list together of gold size vs depth for each coil you used?  We all know that smaller coils are gonna lose depth but I would just like to know how much people are experiencing. I really could use a smaller coil but it isn’t going to be much use if the depth is not there either. Too much loam in my areas! 🤣

I don’t have that list but as Gerry said the 9” packs a punch for those who prefer round coils

A stuff up that catastrophic must only be due to the internal extra wiring to hook up the chip.... it would over-spec the inductance and resistance values. Cut the lead ridiculously short to bring back the numbers. Perhaps they shouldn't have let you video them for promo purposes. Anyway, looks like the sensitivity is still solid, especially so with the smaller 2 coils. 

HI All - cant help myself here. 

Prototype and pre-production coils dont always get the exact same parts as the production and there are reasons as to why the cable is shorter for a couple coils in this circumstance. This shortening of the cable has no affect on inductance values, resistance maybe 0.01%. Essentially no performance change whatsoever and not a 'stuff up' as you have commented.

Gerry and GRGuy received our coils for field tests and have been doing a great job in feedback for us and finding the gold with all three sizes. the best test I have found over the years is just getting the coils on the ground running for as much time as possible to get that feedback. We are very confident the coils will do what they are supposed to do and provide another option when detecting.

Not one size coil will 'see' all the gold as each coil type, configuration and size has a different 'window' of gold it will respond to. this is why there are more coils being made for the GPX6000 and has been done for all previous detectors, not just Minelabs.

If a user chooses to, they could (not should) buy another coil type to fit their prospecting needs. This does not mean that the Minelab coils are not great performers at all, it means that they are now more options to find more gold. Those that wish to stay with the 11" round coil for the 6000 will still have a great coil and if it finds lots of gold for them that is just brilliant. If they wish to get another coil size and run over the same gold bearing ground they may find more gold which the 11" didnt see. I think that there are many that know this but there are also many that have yet to experience this first hand so may be questioning why another coil. We will be releasing videos on this topic in the coming months specifically on the GOLDHAWK coils.

Big thanks to Gerry and GRGuy for their efforts and there are more great videos and images to come from them which will help plus also more release information from Coiltek coming soon!

BTW- that 9" round is a great coil too Gerry... but don't tell anyone 🙂

Fair call Trevor, but to allow coils that are not 100% to be used for video promo is not a good idea. Certainly makes everyone wonder if either the user is doing something wrong or the manufacture is wrong. How soon will CT be focusing on DD coils for the 6000? The old Platypus size/design would be ideal I reckon....I'd buy one

Thanks - maybe DD coils one day, you never know

We see no issues with the coils we have got running for these videos. They are working perfectly.

Thanks for the support!

If you popped out a 10x5" DD coil that would be a great seller.  The 6000's pretty rubbish where there is much EMI about without using the DD coil and the 14" is too big for every occasion so just one single smaller DD could would make the world of difference.  I'd most certainly be a buyer.  I'll be sure to get a small DD somehow.

Hear, hear. The 6000 deserves a smaller, more manageable, DD in the line up. It’s salt and EMI cancel modes are largely ignored with the unwieldy 14”.

As evidenced by this thread, the demand for a small DD coil appears to be high; I would certainly purchase one, and I know other operators who would too. So Trevor, hopefully soon you can change your post above to read, “GOLDHAWK DD coils coming soon!”

Just amazing the amount of sensitivity and depth the 6000 can achieve with different coil sizes on the tiny gold. Would be really good to see them going through there paces on some of the red nasty variable mineralised soils Victoria is known for, there must be huge amounts of small gold laying in those nasty noisy areas if that’s the results on the quieter more homogenous ground. 😊

Completely agree. Actually, I would have preferred a 12 inch DD in the box, not a 14 one. But for sure a smaller DD would be the best selling after market 6k coil. I am actually surprised that neither NF nor Coiltek seem to have it on top of their list (unless I am mistaken). Some technical issues perhaps?
