Youtube is great for knowledge.

Just this week i Youtubed how to fix a leaky toilet. Replaced all the seals on both toilets. $$ saved by not getting a plumber in. Then how to get something stuck out of a zip. (my daughters expensive top stuck in a bag zip ... not my willy, lol) Use it everyday for things relating to repairs of cars, computers, houses.

Then comes Facebook. Mostly couldn't care less what everyone else is doing i mainly use it for knowledge about prospecting. Amazing when your in 100 or so groups and you want to do some research on an area. Ive found spots to go by typing in an area and reading all the comments from within all my groups. There may be a post that starts out talking about one subject but by the time 20 comments are added the conversation turns to a particular spot someone found nuggets. Worth knowing either for places to avoid as its now general knowledge or some place you may want to try. I also do similar research on places within forums.

Instagram I rarely frequent other than for business purposes.  

A concentric coil from another manufacturer.

But since when are we into prospecting for the money?   My goal is only to more often have a glimmer of gold in my hands to show my family... maybe with the hope that I look a little less crazy at the end of the day.  

Im hearing you. My family thinks ive gone mad. Especially after each trip where i dont find gold and say im selling my gear. But a day later im on the forums and doing more research frothing at the mouth ready for the next trip.

I'm going to have to talk Howard into modifying the QED to run DD and now concentric coils. If he could do that and make it auto ground track, then the QED would be sensational. I know he can do do it. I'll just have to keep up the pressure.

Now that might interest me enough to buy a QED. 

Is that some sort of micro chip inside the gpz14 coil?  Dosnt appear to be one in the x-coil. What would the chip do

Thanks Rick,

Got to say my first impression was it looks terrible inside compared to the Minelab 14". Real backyard job.

Im surprised as they look professionally made on the outside.

Im told the Russians have sent my 20" coil so looking forward to its arrival. Not doing the 22x21 x-coil now apparently. 

Could someone please explain what the faulty solder joint means. This picture of the gpz 14 coil shows wires coming out of the receive windings is this the area that's not excepting the ferrite balance correctly on the x-coil? Or is it the tx wire at the top of the coil where it looks like it may be joined/soldered? Photo credit: detectorprospector.com

Will be interesting to see if the coil connection is the same as the x-coil. (chip bypass & gpx plug)

Reading between the lines it looks like its Nuggetfinder releasing the coil.

Having a good Ferrite balance that is fixed to the units operating temperature in this case is best,

I wasn't sure how long it took to get to operating temperature so did my ferrite balance on start up and then again after half an hour of detecting. Through out this detecting session I would check the ferrite on the ground to see if any response was coming from it.

Oh no!  That was my concern about having someone else do it.  If you want something done right, you have to do it yourself.  I was a little OCD and kept ohm-ing out the pins to make sure I didn't bridge any.  I bet I checked it 20 times.  Maybe Jason's suggestions will help.  If you can't get the non-modified coil to work, then this is about all you can do short of sending it to a minelab house to review.  Maybe you won't have to pay for an entirely new machine, just a board.  Best of luck!

Andy

Yeah i know what you mean about being OCD. when  made my 4500 patch lead to run a lipo battery i checked it so many times and then crossed my fingers when turning on the detector for the first time.

Getting a wee bit nervous now about making my patch lead

Sorry to hear about your issues Condor, must be stressful not knowing exactly what the problem is. I hope everything gets sorted out somehow for you. 

Cheers

My 22x21 must be leaving at the same time as yours, my 12" has hit Melbourne so will have it in a few days. Also bought 2 extra lower shafts from Lucky Strike in Geelong, ready to go when the Russian jobbies arrive.

Cheers, Rick

Hey Rick.

Yes both 22 x 21 x-coils are for the two Rick's. I just re read my email and Dave said the Russian maker would hopefully send them in 4 or 5 days. That email was 4 days ago. The Russian guy is flat out making coils but i asked Dave to see if he would make me one if i gave him say 3 months, which he agreed upon. Im happy to wait and have tried not to put any pressure on Dave as its only been a couple of months. Good luck with the 12" i may order that one as well. I recon that would be a good all rounder sized coil. 

I also ordered my lower shafts from Lucky strike but they only had one in stock, now i know why, lol.

Cheers

Andyy and Jin, the balls in your court ?   I don't know who else has ordered them....

According to Dave, a few days ago the 22 x 2's hadn't left Russia yet (they might have now) Although ive got the 10" im in no hurry to put it on. Just ordered two lower shafts for the zed a few minutes ago but they will take a week to arrive. Need to order the plugs for the patch leads which ill do tomorrow as the ones i got where incorrect. Will probably do the patch lead in a week or so.

Good to hear Dave. Only new to the 7000 so wasn't sure if the zed behaved differently when a 14 or 19 was attached. Looking forward to trying these coils out myself soon

If the chip tell the 7000 which coil is being used does the detector react differently when either the gpz14 or gpz19 is fitted? Just asking as wondering when you have used the gpz19 coil as the donor chip for the patch lead and then you fit a 10" x-coil if the detector is running at its best. I would think there wouldnt be a difference, but who knows whats going on within the electronics/software

Quote

Steve Herschbach - The coils are intelligent coils that tell the detector which coil is being used, much like has been done with the X-Terra coils.

Or change the plug on the gpz to suite the x-coil plug. Yes i wouldnt be the first to try the double chip 

I probably haven't thought this out to well but would it be possible to cut off the chip and fit it inside the gpz case behind the plug that connects the coils. This would solve a possible extra connection problem. the gpz14 or whatever you sacrificed and any x-coil would plug in without having a patch lead in between causing possible loose wire interference. Might be a problem though if you tried using another gpz coil that had the chip on the lead. 

Seems ive hit my ? quota for the day Simon so no like for your post until tomorrow by the looks of things. I might have to delete cookies or something to get around this in future. 

Im actually surprised that glue or tape is needed. Never did that with my 5 pin plug on the patch lead for the 4500. Its not like where using the patch lead to lift up a 20kg bag of cement. The wires are soldered, the plug cover goes on - end of story. 

I took my 4500 patch lead on/off all the time. Tugged at it, knocked it and bent it when detecting often. Still stayed together fine. Its not like there should be lots of force on the 7000 patch lead its inside the shaft connected to a coily lead.

So after all that its probably best to follow the instructions sent out by Dave which says use the glue 

One day ill learn to read the instructions first. But at least this thread brought up some good points about getting the enamel off the wire

My last 22x21 Coil was really problematic especially in General Difficult, if I presented a coil like this to Minelab saying it was OK imagine what this would do to the X coils credibility?

Would you say the coil is still usable though JP? Or it displayed no benefit over using the gpz19 

I was just re watching your treasure talk video (below) and it quite clearly shows that General/Difficult is the go to setting in your ground when using a larger coil 

Im a little concerned if your 22x21 displayed problems in general/difficult as im getting that coil. 

As the Russian manufacturer is only building two 22"x 21" coils (as far as im aware of) i doubt much improvement has come about since making your one 

The quote below mentions salt as being a problem once a coil become to large. Was this one of the problems you encountered with the 22x21? Possibly saturation also?

There's a key issue to think about when using larger coils which is mainly why you don't see Minelab going much above 19" and I notice no one has mentioned it here in all the dialogue. 

SALT

JP

 Hopefully not to many questions JP and you are in a position to answer some of them if you have time.

Edit: No need for a reply to this post JP,  I found you have answered most of these questions in previous posts. 

I was always under the impression that Tigers where more aggressive in the summer and browns in the spring. Something to do with their mating/breading season. The last encounter i had with a brown was at the Laanecoorie caravan park when a baby brown shot past my thongs at high speed. Beautiful creature it was.

Good to know that bears dont go around eating people Goldseeker as I have been invited to go back to Canada for some prospecting by someone i met over there.Thinking a 6 month trip might be in order in a couple of years. My mate says head up to Barkerville for some nice nuggets.

Yes it would be good if all our snakes over here rattled a warning sound if you got to close.

Just spent 3 weeks in Canada and Alaska and after seeing 20 odd bears on the trip I reckon bears or cougars would worry me more. Imagine detecting and a bear comes up behind you. Certainly wouldn't detect with headphones there.

I use the hot glue gun because it dries solid and fills the inner part  of the socket between the wires so they can not move at all. It gives a similar effect as a molded plug. I think the liquid tape will still allow for movement of the wires within the socket.

good point, i might test the liquid tape to see what it dries like. If no good ill go the with the glue.
