I've searched the DP archives, been reading DP forever (it seems), certainly on the GPZ discussions, and have yet to see or hear about this unit's operation/performance/settings in Alaska. I'm headed to areas North of Nome, AK next year - and just dotting my "eye's" and crossing my "tee's" long before the trip. Steve has covered Gane's Creek incredibly well, as usually does with a bunch of MD's, but unless I was asleep, he has yet to discuss having taken his ZED up there. I'm looking for advise (beyond carrying a .44MAG), settings primarily since Alaska is not AZ, nor NV, nor CA.

Great Treasure Talk blog by Nenad Lonic at http://www.minelab.com/go-minelabbing/treasure-talk/comparing-minelab-s-sdc-gpx-gpz-detectors comparing and contrasting the Minelab SDC 2300, GPX 5000, and GPZ 7000.

GPZ Coil coming soon.

I think I can promise that Minelab is watching this forum carefully for helpful feedback regarding the GPZ 7000. Once a few more people have one I will start a general suggestions thread that will address general upgrade requests, especially as regards the software. The hardware is not likely to change much. The most immediate thing I am sure Minelab is working on is the coils What one or no more than two coil sizes do you want the most? We need it to be focused so big lists do not help. The main thing is to send a message now about what you want most. I can guarantee the people that matter will be watching what you say with great interest. Some reason why you want the coil would be good also. Thank you!

Well time is coming for me to dust off the Zed and take a walk about in WA again. I keep my eyes out for interesting video's in youtube from time to remind myself of what I should be listening for. The following vid is a pretty good one in that not only does the man find a great patch but keeping your ears on he demonstrates the audio for these beautiful chunky pieces. Granted its all pretty shallow stuff, for the Zed, and he's in Victoria's milder ground but I still found myself figuring the size of his finds just with the audio he presents as he sweeps the Zed. Only things missing for my ears are the complex trebly and deep grunt signals I've heard with my own experience. However the big one in the video gets pretty close to the complicated trebly signal I love to dig on. This video has me psyching up and is a great inspiration :) I hope he keeps finding the good stuff. Me~ hehh I'll get a little something but I hope people here will pick up on those signals and be inspired as well.

The only detector I've used is a GPZ 7000 chasing gold in the gold fields far from the coast with great success. Very recently we have experienced sum huge swells hitting the east coast of Oz, taking thousands of tons of sand away and possibly exposing sum lost treasures. It got me thinking can you kill two birds with one stone? Would there be any problems with using the Zed on the beach ? Is it overkill ? Should I buy a machine suitable just for detecting on the beach ? I know I would be digging big holes and every target because it doesn't have discrimination like sum of the other machines (its the thrill of the chase & the unknown that gets me buzzing) Any input you guys can give would be great !! Cheers ozgold

Interesting thread over on Rob's forum: http://forums.nuggethunting.com/index.php?/topic/11962-what-are-you-missing-gpz/ These settings have been discussed extensively, but I have never seen a post indicating significant amounts being missed by running in "Difficult". Seems strange to think you could miss targets by trying to run quiet so you could better hear whispers. Still baffled by GPZ.

Above is a quote from Jasong, from another thread that hits the nail on the head. Somewhat a forbidden topic on OZ forums, which I guess says a lot about social media. This matter has been touched on by others when speaking about the "new age" coils on the Xs in other threads. While I`m a confirmed and dedicated Z user, I recognise because I`ve experienced the ability of these coils and how they have closed the gap( in the field on undisturbed gold), plus in some cases exceeded the Zs ability. Saying that I`ve also experienced more cases where the Z exceeds the Xs ability. But it is interesting and really says it all about the dominance of ML, their only true competition to their latest serious gold detector is their model it replaced. This has been so for how many years? What are the other detector manufacturers doing? And why is it sort of "taboo" to post about this subject?

Can anyone tell me how this piece relates to the guide-arm connector ???

The Minelab vs. Minelab thread and auto tracking got me wondering again. Perhaps Norvic, Lunk and JP can chime in and shed a little light based on actual field experience with changing ground conditions. About 3 weeks ago we had some rain here in sunny Yuma and the moisture really lit up the clay/silt layers. The Z got really noisy especially in my usual settings of HY/Normal with a sensitivity of 15 +. I tried a variety of changes and found that in order to cover a lot of ground I had to switch to HY/Difficult, Sens 12-. I could run my usual settings but had to slow down to a dead crawl and she still growled and moaned blurring any possible faint signals. Running in Difficult I did get a couple very faint signals but it auto tracked them out. I switched back to Normal and both signals were loud and clear. One of them turned out to be a tiny piece of gold, the other was a hot spot of red clay. What I didn't check was how far I could back off the sensitivity in Normal and still hear the targets. I'm wondering whether in this situation backing off the Sens beats switching to Difficult.

Does anyone have a vid link to a nugget going low-high (filmed after the update only) that shows how deep it was and how big the nugget was? On nuggets up to 40 grams I still cannot get a low-high signal with just one exception and that is squirrly little wiry or thin flaky pieces that flip between high-low and low-high, and with some regular pieces when they get really close to the coil they will flip between the two as well. I had a 65 gram slug of solid smelted gold and it was going high-low on the GPZ. It was low-high on my 45 though. What I'd really like to see are the types of gold that are low-high from beginning to end, no matter how far from the coil. If anyone has some links or has such a nugget and could toss it on the ground and film it I would be very grateful. One reason I'm wondering (ok, don your tinfoil hats) is low-high is so often iron now that I can't help but wonder if discrim might be possible with ZVT tech and there may be some kind of "discrimination update" coming in the future. Also, bonus question: can anyone show me a case where General is outperforming High Yield in depth and sensitivity and what exactly the type of gold (weight/sponginess/etc) is that causes such a thing to occur? Or ground type if that is causing the difference. We see it on the ML chart (or it would appear that way but we don't know for certain due to omission of actual sample defintion), but I haven't found a case with my gold where it happens yet so I'm curious what to look out for or if I should just give up on going back with General after HY unless I have gold past a certain size threshold.

Haven't been able to get out much this year so probably only spent about 20-25 hours on the GPZ mainly trying settings etc. Managed to christen it with a couple of nice little speccis so think I'm starting to work things out. Both were about 6" deep in gravel layers under top clay layer so could have been found with other detectors. One (the smallest) was under some heavy leaf litter too so all up maybe 8" depth? First couple of times out I struggled a bit especially on smaller targets but last couple of outings I seem to have found settings that suit me/my area. Picking up a lot more bird shot now, not that that's good , although I don't think it's as sensitive as the SDC it's not far off. I am picking up a lot more of the BB size shot at impressive depth - they hit loud & clear. The gold has been slow but I'm now confident that once I get it over some good ground it'll be a good thing. I can't remember digging deep holes with as much frequency either. Of course there had been deep holes with the SD/GP & GPX + even with the SDC on mullock heaps but I don't remember digging so many over such a short period of time & a couple of the deepest I've had to dig - unfortunately for junk only so far. The fencing bar will be living in the ute! My main current settings are: High yield/Difficult; Sensitivity - 14 to 16; Smoothing off; Threshold around 24-27

I just recently purchased the Garrett Carrot Pinpointer. I really like it. The issue is the GPZ7000 does not like to be within 4 feet of it. And that is with the pinpointer off. I swing the detector with my left arm. I put the pinpointer in my finds sack on my right rear belt side. Every time I swing right I would get a signal from the pinpointer. My pick, old pinpointer, and trash in the sack, no problem. But the Garrett Carrot sets the GPZ7000 off. I really like the pinpointer, but can't carry it with me. Will have to leave it with my water and lunch and go get it when the rare times I need it.

For about 2 months I've been experiencing a short "cut-out" occasionally, as I'm detecting. The best way to describe it is the way my GPX 5000 would cut out in discrimination mode with the DD coil, it's just like that. It's quite annoying because it disrupts my rhythm causing me to re-swing where it just hiccupped. I just spoke to Minelab, they put me on hold then gave me Jerry's (Jerry's detectors) number and asked me to call him. That seemed odd. We talked about the problem for a while and decided the first thing to try is, connect the headphones directly to the detector to determine whether the module is the issue. Has anyone else experienced this?

The GPZ documentation states that General mode punches deeper and Extra Deep punches even deeper than High Yield mode. I've hammered a patch in High Yield and today will switch to General mode and regrid, and will repeat in Extra Deep. Has anyone out there had success with this, and if so, are the deeper targets more defined in these 2 deeper modes, any tricks to listen for? Or are these deeper modes only for larger nuggets, will the 2 modes punch deeper for smaller nuggets too?

Gary Schafer of Minelab America announced today at the GPAA Las Vegas Show that a 19" - 20" coil is officially in the works. Great effort and therefore time are going into trying to keep this coil as close to the weight of the stock 14" x 13" coil as is absolutely possible. No projected time frame for release was announced but since they are still hard at work in it the implication was not any time super soon. Sorry, wish I had more than that to offer but at least you know now a big coil will happen before a small coil.

I seen this issue on the oz forum...is anyone besides me having a problem with the 12v charger for the gpz? I have two- one for my ctx and one for the 7000 and they both behave badly...when I plug one into the 12v outlet in my truck it starts flashing red while charging. The manual says this means there may not be enough battery to pull juice from the truck battery...my truck battery is brand new. So, I carry a small invertor and plugged that into the 12v outlet, then the battery charger into the inverter...the charger worked fine but my truck battery was drawn down and I had to jump it... so, the second question is this; does the inverter draw a huge amount of amps to go from 12v to 110v to charge a the zed battery??? Also, is the sensitivey of the minelab chargers adjustable ???? thanks fred

I am looking for a new flex link for the swing arm helper that broke from wear. Decided to check the Kellyco web site since no one seems to have that part listed and see that the gpz7000 is now listed on their site for $7999.00 US.

I'll start with the ugly. The lower shaft on the GPZ is made out of what appears to be a porous ABS plastic. Down close to the coil it is also ridiculously, disgustingly. unbelievably thin. Now the bad. My feet are shaped like a 17" elliptical mono coil. And worse yet is the control cable to my brain sometimes looses connection. So I was detecting on some very steep and slick ground and stumbled and set my GPZ coil down instinctively to catch myself . I have done this at least a million times with every detector I have ever owned and never damaged any thing. Not so with the Z. The shaft broke at the coil ears. I cobbled it back together with a couple of sticks, some electric tape and a spare shoe lace and finished the day (it was 2 mile+ hike into this spot). Now the good. Doc had one in stock and went to great effort to get it in the mail that same day. I somehow get the feeling that this shaft was designed on a computer by a computer genius who's computer told him that this design was adequate. It's not.

I found this video for you ZED users showing some accessories that you might find useful for protecting some of the bits that matter, They were posted else where but after I watched the video then this video popped up so I thought it might be usefull.. john

Steve likes rumors and I heard a good one recently. I heard the GPZ 7000 will be put on sale with a notable price drop in the near future. Can't say much more than that right now, but I heard it from a reliable source. Just about all the ML detectors have gone on special offers in recent months and it appears the flagship 7000 will soon join them. So if you've been wanting one and waiting, you may have a special opportunity here shortly.
