Thanks for the response Trevor...the other guy uses core cell in their coils its good stuff but expensive the reason I know is I’ve bought plenty of for use on boats . Do you use a  light weight foam coring as well?

strick 

Yes we do... A foam inner core which the windings are laid in - lightweight and strong. ?

“Pressure regulation pad to keep out water and dust but assist to regulate the pressure in the coil to minimise any swelling and induced noise”

 

Hello Trevor,

just purchased the little 10x5 for my 6K and will be using it for the first time in the mountains this week.  I have a question about using the pressure regulator tab, as the places I intend to use it will be over 5000 ft (~1500m) above my current elevation, I assume my coil will be a little puffy when I get there and may need to lose a bit of air. Then when I get home it’ll be a little concave and I’ll have to let some air in.

Anyway my question is how much noise have you noticed happens from when the coil is going through pressure changes and to what amount of elevation change have you noticed  that happening?  I’m curious if ML Coils are affected by this as well?

Thank you, and I really appreciate the build quality of this coil, you guys did a great job on it. I will certainly post my successes with it when (and if ?)  they happen!

Trevor, I just received my 9x14 GoldHawk and was wondering if it is flat wound, bundle wound or a combo of the two?

He's said earlier in another post or thread they're bundle wound.  The thing I've noticed which in a way confirms this is the 11" stock coil is rather insensitive to tiny targets on the edge of the coil which you would expect for its partial flat wound design for those that tilt the coil on its side and use it as a pinpointer.  The Coiltek especially the 10x5 I've put the most usage into has hotter edges which fit in with it being bundle wound.  Anyone that's used the Evo's or Elites on the older GPX will be familiar with what I'm talking about.  As targets get bigger yes the 11" sides pick them up well but its the little hard to find targets they struggle, where as the bundle wound coils having all their windings right at the edge really work great as pinpointing coils.   I think it also explains why the 11" seems about as sensitive to tiny targets as the 10x5" and more sensitive than the 14x9" and also possibly part of the reason the Coilteks run a little quieter.  Just my uneducated observations.

I got a 9" Coiltek in today, gave it about a 3 hour run. Unfortunately, while it does help the EMI issues a bit, it does not help enough in my case to make the 6000 a pleasant detector to use in some problem areas still. Again, not anywhere close to a city, powerlines, or really anything other than maybe cell towers that might be producing a lot of EMI. Yet, certain areas the 6000 just really struggles.

On the bright side this coil seems to get rid of the times the detector just completely freaks out and loses total stability. I can run the detector in one of the places I considered "undetectable" (with a 6000 anyways) previously, but it's still so bad that I have no desire to run the machine there.

It also seems to have some bump sensitivity that the stock coil doesn't have, but I think that as with the EMI, the bump issue is the machine itself unable to cope with input, as it's random and not always repeatable, and happens more when the EMI or ground is worse. 

I'm now pretty certain the 6000 either has some large scale design/manufacturing defect, or it has issues with some frequency from cell towers or some other equipment particular to the US, and specific areas of the US too, but not in others. Or there are both design problems and field issues related to some unknown transmission equipment, together. My 6000 seems to perform about the same as other 6000's in similar locations so I don't think it's unique to my machine.

There are simply too many variables to eliminate with zero communication from Minelab on the problem. All I know is this coil doesn't fix my issues, but it does make them slightly better. And those issues vary greatly between different locations. The one constant is the 6000 itself.

Sorry to hear that Jason.  I was hoping your problems would be solved.  While my GPX is certainly improved a lot by the Coiltek coils it was likely mostly because I had a faulty stock coil that I had so many problems which obviously was faulty as the Minelab service agent faulted it too, they didn't just replace it as a precaution as they were able to fault it.

My replacement 11" is more stable for sure than my old one, it still has the typical EMI issues and hates being tilted on it's side and the numerous quirks the GPX has which are improved quite a bit by the Coiltek coils.  

As you likely saw in my video the Coiltek coils for me are completely not sensitive to bumps, I could cut down a tree with one even on highest sensitivity and it not react, so it's strange yours is bump sensitive, you're the second person to say they have bump sensitivity now too as Goldseeker5000 has bump sensitivity on his 14x9".  I wonder what the cause of that could be and why some are and some aren't, so strange.

We have 5G mobile around where I've been able to use mine, and when a bit further away it reverts to 4G but that doesn't seem to affect the stability of the detector.  I think people would be extremely surprised to see how close to civilization I look for gold here so EMI is always an issue and coming from the GPZ which basically has no EMI problems the GPX was a challenge.  You may end up having to sell up and try an Axiom, it really sucks your problems not solved though, especially after mine was solved the same way.
