Coiltek Coils For The GPX 6000 - Confirmed!

[jasong]

I'm over it. I got this Coiltek in hopes that it would fix the issue, or to at least let me see if there was a problem with my coil or detector so I could either send it for repair if there was an issue or sell it without feeling like I'm ripping someone off. But I am confident it's nothing particular to my machine or coil now, so I'm just going to sell it and get an Axiom when they are released, as I originally planned. Anyone looking for a 6000 with 2 batteries, 17" (new), 11" monos, 14" DD (new minus a brief EMI test), and a 9" Goldhawk, PM me, I'll be putting it on Ebay for $4400 once the Axiom comes out, but will sell cheaper here. 

Anyways, didn't mean to hijack the Coiltek thread with yet more 6000 issues.

The 9" round actually runs just fine when I get the machine away from whatever is causing the EMI. It's about on par with the 11", it definitely cut down on the times the detector lost total stability too. For people who are just having a bit too much EMI, it's probably a good upgrade. But in cases where the EMI is just driving the 6000 totally crazy, always, it's not a magic bullet. 

I continue to have minor issues with this coil falsing/bump sensitivity though, that's about my only complaint specific to the coil itself. It seems to happen more when the 6000 is on the verge of getting overwhelmed with too much input. It's not coming from the cable or connectors either.

Finds the gold just fine though in places the 6000 decides to work. Most of this came from jamming the coil under sage brush today.

Jason do you have " Single Wire Earth Return " (SWER) Power Lines in your area They were used in remote areas here in Victoria Aus. to distribute house and farm power, if so that could be your problem.

It does seem it is used in the USA.

He’s in Colorado- lots of secret defense related sites and infrastructure is located there, perhaps he’s getting some interference from something like that? Especially as he said it happened in various places and not others, maybe from going in and around valleys and hills created various signal shadows.  It would have been difficult for Minelab to anticipate all the different types of EMI the detector would be encountering during testing, but I’d think adequate internal shielding should have taken care of all that.

@jasong I’ve tried to PM via the forum but it says you can’t receive messages .

In the field right now, will respond when I get back in tonight. Weird, I deleted some messages to free up space a bit ago. I'll have to delete more again sometime.

A couple of hours in soggy ground with the 9” Goldhawk.

Is that your camera or phone creating the EMI we hear? Seems whenever you move about, it gets worse...Plus, where do you get those 3D printed mini pans from???

I said I'd post this a while ago but forgot, and this is why I think having a pressure vent on coils is important, to Aussies it probably means less as they're in a big land of flatness but to countries with altitude it's pretty important.   It's good to hear Coiltek have a vent, although I'm yet to find it, it's very obvious on other brands like the original Minelab GPZ coils, Nugget Finder coils and X-coils but I certainly can't for the life of me find it on the Coiltek Goldhawks.  It's advertised as having it and said to be under the skid plate, odd location to put it seeing a lot of people tape their skid plate on, in fact I have to tape my 10x5" Goldhawk skid plate on or it falls off in a few minutes.

This is what happens to a regular packet of corn chips in higher altitudes, I specifically didn't open this packet before heading uphill so I could show what happens, it happens to my chips all the time if I go up a bit higher than low level ground, they're a bugger to open when they're like that, they make a big explosive pop when you open them too ? I usually open the packet before going up higher so it doesn't happen.  We also have to be careful with other food items that may pop or explode, especially liquids.

I can't imagine having pressure like that inside a sealed coil would be a good thing.

If someone can show where this elusive vent is on the Gold Hawks that'd be appreciated as I sure can't find it on either my 14x9" or 10x5".
