 Minelab would rather sell us the SDC2300, than offer a small coil for the 7000. Likely they figure that small coil option for the 7 would hurt their SDC sales. Plus they probably have a 7000 replacement in the works and this whole story will be forgotten  history when that comes out.

Steve posted a really good picture of where Minelab sell the most detectors, I can't find it now for some reason but it was a real eye opener.  Australia was quite a small market in comparison to some other countries.  I think there are far more GPZ's in Africa than we realize.

I honestly feel a smaller coil should be available for this product and wish and have repeatedly asked for this to be addressed over the years.

With GPZ bigger means more salt signal, I feel the Russian 17” has really come close to the sweet spot for a max size general purpose coil for the GPZ in most areas unless specifically chasing deep targets in known locations. Ideally I feel a 12” round, 15 to 17 inch elliptical and 17 to 18 inch round would cover all the bases with a max weight of no more than the GPZ14 coil on the bigger variants.

I would like a 17in round and a 22in round. I just don't want them to be like swinging a pallet of bricks...

Hi Dale, So the ML 19" caught up on you. How's the shoulder?

Good luck out there.

For me there is no dream size, they all have there place. But I am loving the 10" X coil at the moment due to the places I can use it that I had no hope with the ML 14" on the Zed. That little coil is ideal for the terrain I detect in & the small size of our gold. I guess I would like an even smaller coil. Elliptical would be good.

For me a small coil was always about physical dimensions and tight locations as I was satisfied with the GPZ14 ability to hit small gold while also having good depth on larger gold. Hunting in hydraulic pit boulder piles, narrow boulder filled gullies, and thick sagebrush have all been areas where the GPZ is effectively shut out from getting into the nooks and crannies. Depth is not everything - you have to get the coil over the gold. With the GPZ 14 already being 13" wide a 12" coil would offer minimal benefit for these situations. I wanted something 8" max on the narrow dimension for this type of detecting. 8" x 10" elliptical or 8" round or even smaller.

Don’t think a coil of those dimensions is practical or possible with current ZVT tech Steve, also IMHO when you start pulling the GPZ down into those coil sizes I think Minelab have pretty much covered the smaller gold you are chasing with current offerings, kind of like a diminishing returns equation I would have thought.

I think for a smaller coil for ZVT we will also need to see a much lighter overall platform to keep things in balance and usable this then means the use of larger coils then becomes a problem so maybe two variants of ZVT would be better, a small coil super light optioned version and a larger big nugget hunting version for guys like myself? Believe it or not I find the weight of GPZ to be very useful when chasing edge of detection targets in flatter terrains, the weight gives control.

I’m glad the GPZ weight is good for you JP. I was just explaining I want and why but it’s kind of moot since I don’t have a GPZ anyway.

One of the first X-coils ever made was a 8x12" that the manufacturer made for himself.  JW's got a 9x10", I see quite a number of people would prefer smaller coils than the current offerings too, maybe a 8x10" might be worth looking into or even smaller or at least the smallest elliptical that can be made, that may well be the 8x12" for all I know.

It will be interesting to see what coil sizes Nugget Finder come out with as their range.  Obviously so far there is a 12" round on the cards for them and that's proven to be a good performer in the X-coils, it seems to maintain sensitivity to really small gold similar to the 10" which I believe is because the 10" is bundle wound and the 12" is spiral.  It comes down to if size matters and for a number of people in certain locations it does.

I think people who have funded the high cost of the GPZ and learnt the machine to the best of their ability would rather keep using it and buy a smaller coil for it than buy and learn another detector for chasing the smaller bits with a small coil, that's my opinon anyway and when I do end up with a GPZ a small coil is certainly something I'll be getting for it due to our rocky terrain and small gold.  I guess too when hiking into a location it's easier to carry a spare coil than it is a second detector.  I've decided I want to see what pans out with the pending release of a new detector from Minelab if it does happen before making any crazy decisions, a guy only has so many kidneys to sell 🙂

Thanks everyone for keeping this thread sensible and on topic, quite often any thread like this can turn into the wild wild west rapidly lately.  It's good to hear different people in different locations perspectives on coil choice so thank you for the replies so far.

If they made a smaller coil lighter GPZ, that sounds like something I'd be interested in.

      Well, I tried a new way to get out to this new gold area I found.  The gold seemed fairly small, but I had to hike in at least 3 miles to get there.  So I tried to drive in another way in hopes of only having to hike in a mile.  Of course Google Earth made things seem better than they were (almost like I could drive right there), but in the end I only cut about a mile off the hike (one way).  So now I had a decision to make … take my GPZ 14" coil, the GM1000, or what I call my Midget Coil (10" Xcoil).  GPZ 14" about killed me getting out there last time so that was out.  I love the GM1000 on bedrock, but some of the bedrock here was very hot.  Usually in those cases, I will go to my GPZ 10" Xcoil, which I venture to say is at least on par with the SDC 2300 (with the exception of being a little bigger).  And the Xcoil is still a pleasure to hike with.  So off I went.  
      I started out hitting the areas I had been to before and got some good signals.  First piece was only about .1g.  Then I started finding slightly bigger .2g pieces.  Most of these seemed to be what I call runners.  Those are the ones in washes that I find on the sides of the wash, trying to run away when they see me coming.  The larger coils tend to lose a bit of depth when checking the sides and depressions.  The 10" Xcoil, however, does very well getting in there.  
      Overall, 5 pieces were found (total .75g).  Not a lot, but at least half of these finds were detected very carefully with the 14" coil and were missed.  The Xcoil was very clear on all but a 1 grainer piece that was about 2" deep on it's side.   All in all, it was just a fun day crumb chasing.

      I had my first outing with my GPZ about a week ago with JW, my back was still terribly sore at the time from an injury so I wasn't really doing well and had trouble digging targets, and we were in terribly heavy rain so I was off my game.  I went back to the same spot today, the weather was much better, in fact it was far too hot for me.  My back has improved a lot, I lasted about 3 hours which I thought's pretty good, my longest detect since I did my back in.  This particular place I've always called my Nemesis as I could just never do well there.  I've been there probably 25 times and only found gold three from memory.  The first time with my Gold Bug Pro which was 1 bit, then the QED with 12x6" X-coil which got 1 bit, then the GPX with 10" X-coil which got 1 bit.  I've never got a bit with the Nox or Gold Monster here even though I've used the Nox the most I'd imagine and I'm the most comfortable on it feeling I can use it pretty well.
      I had a lot more faith in myself today as JW has done very well here with his GPZ and 10" X-Coil so now we were both driving the same machine surely I could come away with a piece.
      I threw my little ferrite super magic ring on the ground and waved over it, no response unless I rubbed the coil on it so maybe I don't need to do that anymore after doing my Quick start procedure the other day so I just got stuck into it.  I've had a few skilled operators suggest I use Manual instead of Auto or Semi Auto, that made sense to me with our mild soils here so I was in manual, I raised and lowered the coil and had no response from the ground so I assumed that I didn't need to do anything so I just got stuck into detecting.
      I first tried all the mountain goat one gust of wind and you're dead terrain, I get a bit wobbly detecting this stuff as I'm not so good with heights.
      My first target was a shotgun pellet.... not unexpected, there are many of them around here....

      That's good though, it means the detectors working well 🙂  I'm not used to the target noise of the GPZ on these small targets yet, bigger targets sound similar to the GPX but these small things behave differently, it's sort of a wobbly noise, different to the GPX.
      I kept going, detecting closer to the cliff.....

      Scary!  I did get a target in this area, it wasn't on the surface as it remained after my first scrape and moved on the second, unfortunately, a tiny little bit of some sort of junk

      I was super impressed with the sensitivity of the 12" X-coil getting these tiny little targets, Gold Monster size bits of junk.

      I really thought I had a nugget in this photo above, this was just before my dig..... turned out to be another shotgun pellet stuck in the schist bedrock 😞
      Now the sun came out, it was terribly hot and I was frustrated looking at the nice cool water below me while I'm up here sweating badly wanting to jump in it to cool off, I really struggle in heat so I moved away from the cliffs and jumped in my car to go back into the terrain JW found his bits last weekend, it's very close by and I could have walked if it wasn't so hot and my drink had run out already 🙂
      This next area has lots of good bedrock and didn't seem as junky with the pellets, the issue here is the power lines, I dropped my gain down to 14 from the 20 it was on previously so the machine ran nicer as I couldn't put up with the power line noise as the spot with the bedrock I wanted to detect was basically under the power lines.  As I detected further away from them I cranked my gain up again and as  I got closer lowered it down, quite easy to do on the GPZ as you just leave it on that option and adjust as necessary.

      Why do they always put these right where the best bedrock is... I'm sure they did it on purpose. 

      Nice bedrock though... I could see a number of fresh looking dig holes around, I suspect JW's handy work, he was good though, all necessary ones were back filled. 😉  The funny plants are getting annoying, there is a plant that looks like that if you grab onto it and try rip it out it spikes you to death so I wasn't game to touch them, just worked around them.
      I noticed an area with a lot of dig holes but it was virtually right under the lines, I figured there is no point doing that area but the dig holes seemed to go off in a direction so I instead went down rather than follow the digs and it was only 15 steps from a dig hole and I had a target, quite faint but very obvious.  At this point my gain was on 12 to calm down the power lines and I had the detectors volume on 4 as the Steelphase SP01 was attached to the Wm12 and gave me all the volume I could ever want.  I did notice if I got between the WM12 and the detector sometimes the audio dropped out for a few seconds and picked up again if I moved, it seems it doesn't like passing the audio through my body, is this normal or is my WM12 a lemon? I would think it's pretty normal passing wireless though your body.  I tried changing frequencies but made no difference.  I might just use my Quest Wirefree mate as it doesn't seem to do that, similar thing to the WM12 anyway.
      I dug the target thinking it's probably going to be another shotgun pellet, it was doing the same wobbly type noise, hard to describe the noise....  I did a scrape with the pick and it was still in place, getting hopeful but the bedrock was quite shallow so I just started taking scoops out with my plastic scoop and waving them over the coil, narrowed down a target and it was a bit of gold! Awesome, my first GPZ gold, a tiny little thing....  I rechecked the area and the exact same noise was still there, it sounded like I never even dug the target.  So I kept scraping it out and waving the scoop over my coil, a few more scoops with and I had the target. Boom! Another bit of gold.  Two from one hole! this doesn't happen to me often.

      The spot I got them!

      You can see the detector sitting in the spot still where I got them and if you look up the damn power lines!

      The two little guys! 🙂  I was done for the day now, it was too hot and my back was pretty sore.  I had a goal of finding a bit of gold then I was going to leave, it's lucky it happened when it did as to clean the little bits I had to use the last drop of moisture in my body, my spit came out like pasty thick molasses to clean them.  I stumbled back to my car and was lucky.  I found a few fruit trees on the walk that were covered in fruit.  I got my fluids up eating a bunch of apricots and a few plums.


      I picked a few for the road too

      Washed down my KFC with them.
      Time to head home, my wife had sent me a text message while I was detecting saying I've had a parcel arrive, it was the two coils I've ordered to start exploring for some new ground, I wanted some ground coverage so I can explore and find some ground JW hasn't already done so I think this is partially why I called it quits so early in the day, I wanted to rush home and see the new coils 🙂


      15x10 and 17x12"
      I've tested both of them out already in my backyard, both detect my bits of gold I found today, that means they'll be my perfect exploring coils.  I hoped they'd both still have the sensitivity to small gold which they do.  I shouldn't say my bits of gold either, my wife confiscated them off me, valentines day gift she said as its valentines day here today 😄  It's the first nuggets I've given her so that's OK.
      Time for the weigh in.


      Not too bad! Happy with that.  I really like the 12" coil, it's going to to be my everyday use coil.

      I recently broke my stock dd and replaced it with the 9x12 concentric. For the life of me I could not ground balance the machine in snow, just an inch or 2 it would false out like crazy. I did repair my dd but it is slightly out.
      Sent the 2 coils to Garrett along with the AT Pro and they repaired the machine, put in new firmware and confirmed the dd was out of wack. Went to use the machine over the weekend and still can't gb it with the concentric.
      Does anyone have a 9x12 concentric on an AT Pro and can confirm the issue? Not sure if it is the snow or the machine is marginal and sensitive to the cold or not.
      Thanks

      So took the gpz out for couple days were I hunt managed to find out that my extra waterproofing didn't work after 20 mins of first day with xcoil so was back to std 14 on day to all and all we had good trip pulled 5 grams for 2 days and 3 nice bits including this one 
      It was all creek hunting and was defanitly impressed the the zeds depth 

      Just hoping with few days sun in a bag rice the xcoil will work normaly again.. Guess I will have to wait for nf coils to be realesed for water ones as the std 14 took on water to even tho they ment to be submersible to 1 mtr

      So my gpz turned up on Friday and I'm super loving it and my 10"x-coil should be here Wednesday, as soon as I got it out the box I grabbed my we test gold ranging from 0.025 to 1.71 gram and shot out to my we test area that happens to be gravel pit in known gold area.. I found for my area in NZ I was geting the best depth and response on general and high yield with audio smoothing off.. I had a play with the ferrite ring with ground balancing then factory reset and ground balance with no ferrite ring.. So my question is does the ferrite ring gb affect depth and sensitivity at all in low to medium ground. What I noticed was our soil and were I hunt in creek beds you hit pockets of high black sand then less etc. I didn't realy notice any difference in performance but I do think that the ferrite gb did run quieter in the ground over all. Does anyone have any tests or input on ferrite balancing vs no ferrite? 
      I plan to get out this weekend for my first hunt with the 10 xcoil all going to plan. So will be sure to put up a link for the YouTube video when made and my finds if any lol I'm checking out new spot
