X-coil Connection Update

[jasong]

You aren't the only one JP, look at my posting history and you'll see I've asked every tough question about the X Coils I could think of asking even if it ruffles feathers, for a month ongoing now. And I'm buying my own coils in order to answer the questions people are not interested in answering for me.

I also mentioned the business model in a post a few days ago. And I've pointed out a number of times that the only real conclusion here with the silence from ML and other companies is what I think you are also hinting at yet contractually unable to say: ML themselves or another 3rd party ARE working on a range of legit licensed coils and this Russian company put their coils out quickly before proper testing in order to make money before the legit coils were released. Feel free to correct me here if I've read between the lines too deeply and come to a wrong conclusion. I think I'm probably on the right track though and I don't like that I'm probably going to cut my coil just to find this out for certain down the line when I wouldn't have had to do it if I waited, but c'est la vie.

I'll be more than happy to test some of these concerns and put them on video. The saturable soil thing is going to be an issue though as most the ground I work is probably as mild as it is in NZ. But i do have a yellow ferrite to test on. But if there is anything in specific you think needs to be tested, tell me how you think it should be tested here and I have no problems putting it on video.

If you think it's not getting enough exposure, this is a good chance to change that. I have some 4 millions views using Minelab products and if just include the keywords "GPZ 7000" in a video it will usually find it's way to the front page of Youtube search on the GPZ for a while, sometimes Google too. I'll post here too which also get a lot of exposure.

As people are aware I was able to procure a dongle so I could use the coils but as has already been shown this is easily circumvented by anyone willing to sacrifice a coil to do so

 - - - but the coil isn't sacrificed

Back in 2015, we asked Minelab for smaller coil options for the GPZ and they said you can't wind enough wire (1 mile in the 14" coil) for the GPZ to operate properly in a smaller coil profile. Well, they have been proven wrong and some creative person has provided a solution for the customers. Maybe now they will listen to us...we've waited too long!

Based on my conversations with Dave, he has no technical knowledge about how or why the Russian coils are performing better than the standard coil, hence his lack of interest in internet debate on their merits.  He tested them and is confident they are an improvement and he's satisfied to leave it at that.  He's not promoting them, they're promoting themselves.  Dave was already making a damn fine prospecting pick and by happenstance ended up testing these coils and now as the sole distributor.  

The Patch Lead will remain a concern, but so far I'm the only one who has f'kd one up.  Whether my soldering skills or my $29.95 Walmart soldering iron turned to max heat, others have succeeded where I did not.  

I'm sorry Jasong isn't in a position to do the methodical testing he's known for. There's quite a few of these coils out there, but many users are not internet hounds interested in this discussion.  

We've all seen the "detector wars" of the past, and JP was very often at the center of controversy.  Our moderator won't let that happen on this forum and I very much doubt you'll find Dave in the middle of any controversy on these coils.

Surely there is test equipment (oscilloscope?) than can test the like of these coils in different scenarios so the yay or nay is not left to up to yayers and naysayers? Otherwise there will always be a ‘do they or dont they’ which costs us the consumer in the long run?

@JP:  I don't know why you say "Sacrificing a coil" to make an adapter plug. There is no sacrificing a coil at all. You cut the chip end off & wack back on a female microphone plug on the end of the cut off coil lead & by using the adapter plug, that now has the chip in it, you can still use the "sacrificial" coil just the same as any of the X coils. Or are you just trying to be  a scare mongerer? Unfortunately for Condor, he just had a bad experience. Shit happens, but he will get on top of it & wont look back. Good luck Condor. I know you will love your X coil/coils.

JP...on another note. When you say you found gold straight away with the x coil/coils, was it on ground you had already been over with the ML 14" coil that was no longer producing for you? That has been my experiences, & it seems every body else's swinging these coils.

Best of luck out there

JW?

When I was doing the prototype testing for the GPZ 7000 the initial coils had GPX connectors because the board was in a GPX housing, once Minelab went to the current housing the connectors changed so I had to go to an adapter to use the older GPX terminated coils on the newer housings, THAT then opened up a whole new can of worms with extra and unacceptable noise thanks to the extra connection. I personally DO NOT want to use any Minelab coil with a double connection let alone the hassle of having to use the X coils with one. In EACH and every case it has ALWAYS caused problems with noise!! The proto GPZ was a nightmare to use when it had GPX connectors on it, an absoute nightmare!! The pins on the GPX connector allow for way too much movement for high end electronics like the GPZ!

JW you can colour whatever your saying with whatever brush you care to use, you can also imply I am scare mongering but at the end of the day you would have to for sure have known about the X balance problem with the Ferrite and chosen not to mention it in your reporting because lucky you it is not an issue in your area (nor in Russia BTW), but what about all the other people around the world whose circumstances are different? Tough Titties for them I suppose? Is the distributor going to drive to every person who ends up having a problem with a dodgy connector or was this just an isolated case because it was up on the forum? 

I find it fascinating how you think because you are getting away with the coils in NZ that you automatically assume every one else will have the same experience? You even have the audacity to suggest I've been succesful with them supposedly mirroring your wonderful experience!! But of course you do have the caveat of your benign ground and 'In my experience' to hide behind when people have problems or if all else fails you can do what your attempting to do to me, discrediting their feedback as scaremongering or some such thing!!

I'm often at the centre of lively discussion because often I'm the guy with the knowledge who feels compelled to keep everything factual, thats my job with Minelab and is what I've been doing for well over 20 years now! People might NOT find the salient facts appetizing but facts they are!!

That's a good question Kiwi, but appears to remain unanswered. Why?
