Actually it is a bit early as I need more time to use both the ATX and SDC together the next two months in order to give a more comprehensive and definitive reply. Still, I did compare both in the limited time I had using the 8" mono coil on both. This would be an optional coil on the ATX and stock coil on the SDC.

The bottom line is the ATX at max sensitivity 13 struggles to keep up with the SDC on it's standard sensitivity setting of 2. The SDC has a clear edge. But it is kind of like comparing the White's GMT to the Fisher Gold Bug 2 on small gold. I am giving a nod based on grains of gold and fractions of inches.

On the flip side the ATX costs less and has optional coils. The SDC has a hard-wired 8" mono coil. Will the SDC with 8" mono hit a big nugget as deep as an ATX sporting a 15" x 20" mono? I am not taking that bet. Those optional coils however drive the price of the ATX up and if big gold is my goal I am grabbing my GPX.

If both the ATX and SDC had identical responses on gold I would grab the SDC. It is lighter by over a pound and just plain feels better on my arm. The coil on the SDC is impervious to falsing when knocked about or rubbed on the ground while at max sensitivity I have to keep the ATX coil as close to the ground as possible without actually touching it. The ATX requires extreme coil control whereas with the SDC you do not have to even think about it. Just put the coil where you want. It is far more natural and effortless.

After 40 years in retail detector sales I have a bit of a sixth sense for what sells. The SDC has the undeniable benefit of the Minelab name. The company was literally built on gold detectors. Many prospectors will look at an SDC who will not even consider the Garrett, especially in Australia where the price is much closer and Minelab has the home team advantage. Even in the US most serious prospectors use a Minelab.

It is telling that when you visit the ATX Forum on Findmall that nearly all the gold finds being posted are by beach hunters. The silence from Australia is deafening. I seem to be one of the few people willing to give the machine a fair go prospecting. In defense of the ATX however this is because most anyone who have been at this for many years now is already sporting a Minelab SD, GP, or GPX. Almost nobody doing so is going to put them aside for an ATX. More than most I like competition and so am willing to give machines like the ATX a try and a kind word.

But reality is what it is and the ATX like the Infinium seems to be settling more into a role as a water hunting machine. The choice of housing is killing it for prospecting as I do believe in a light weight package with standard knock resistant coils for under two grand it would have been a home run. Units keep going up for sale as being too heavy. The absolute easiest way to compete with the GPX is on ergonomics and despite all odds Garrett managed a fail there.

I predict despite the price the SDC will see more uptake in the prospecting community. And in general it has a certain cool factor due to the way it folds up that will appeal. It is only 1.2 pounds lighter than the ATX but because it is so compact by comparison when folded up it gives the impression of even more differential when you grab and heft the two units. The SDC is kind of the iPhone to the ATX android.

It is all a sideshow. What is the best metal detecting system a hard core dedicated prospector can invest in? A SD/GP/GPX Minelab. What is the second best? A used SD/GP/GPX Minelab. The ATX and SDC are kind of slugging it out for third place.

Well, that reply got more long-winded than I intended. Despite similarities the ATX and SDC are pretty different units with different capabilities at different price points. Both will drift into niches with the ATX leaning beach and the SDC gold prospecting. Both will sell and both will have forum based fan clubs. Just my opinion but I rarely end up wrong when making a call on marketing issues as regards detectors. I made a living doing it for nearly 40 years.

For me personally the Minelab GPX 5000 is my bread and butter detector. I count on it to pay the bills. I will continue to use the ATX. I will have both it and the SDC this summer in Alaska. I have to be honest - when I want to put the GPX aside in favor of a secondary PI unit to look for smaller gold or wiggle around in the brush I already want to grab the SDC. It just requires less effort than the ATX to get results. But I can find gold with the ATX also and will continue to do so just to show it can be done. And with my Fisher Gold Bugs also for that matter.

Finally, both companies have done us a favor and offered us an option of getting housings developed and built for the military. I think this is really fun and interesting. I get a bit tired of a box on a stick with a coil on the end so nice to see some original thinking at work here. But that also leaves on the table the easy idea of producing either unit in a straight up traditional lightweight non-submersible design at lower prices in the future. I have hammered Garrett on this and Minelab deserves no less. The military housings add weight and cost and both detectors would be very welcome in traditional packages weighing under 4 pounds and at lower prices.

There is a bigger picture. If a few Africans can be enticed into finding gold with the SDC whether it sells elsewhere could be inconsequential. It folds up into a package a guy on a bicycle can carry in a rucksack. It is virtually indestructible. It uses commonly available batteries that do not need charging (try that in Africa). It is a no-brainer to operate. Turn on and go. It is impervious to most ground mineralization, making it even easier to operate. Turn on, detector make noise, dig nugget. It is that easy. And the bias to small gold will produce easy results where other detectors fail. Most importantly - this thing will be hard to counterfeit. Minelab once again stands to make a bundle in Africa if the SDC catches on there.

Hi Steve, I enjoyed using the ATX, it's the first time a PI has come out that actually competed with a Minelab in my neck of the woods, it's a shame there was so much touch sensitivity and it was soooo heavy, otherwise it would be a fun detector to use.

Our main concern here in OZ is mineralization, there are very few places that aren't mineralized so a detector has to work well in those areas especially after having Fine Gold timings on the GPX, in quieter ground the ATX and SDC have similar sensitivity (in air depth), but when you add in the bad touch sensitivity and the weight difference the price is really the only drawback for the SDC.

Hi JP,

A whole lot of heads probably just spun from that post. I know better but some people think you never use anything but a Minelab and would never, ever, ever post finds with anything else. You just proved them wrong.

I try to be as fair as I can but at the end of the day when I am not playing around trying stuff I have to just grab what I think is going to work best for me. I know you do the same.

Thanks Steve for sharing your insight with both the ATX and SDC 2300,  I know you'll limited to sharing more having spent little time with both using the 8" coil.

You had mentioned the SDC is lighter by over a pound and just plain feels better on my arm, The part were you mentioned (just feels better on my arm) is what I am experiencing now with the ATX having the arm-rest slide further back.

Having long arms, The ATX just didn't feel right always felt the arm-rest with strap should be mounted further back at least flush with the back of control box.  Having an extra arm-rest from the (Recon) modified the Recon arm-rest to slide further back actually 1.25" inches back so now the rear portion of the arm-rest is flush with the rear housing.  What this did was balance the detector for me due to having long arms, The strap is secured further back on my arm doesn't feel off balanced now at the rear.  So now I use this modified Recon arm-rest with the ATX, makes a big difference the ATX just feels so much better and swings well.

See a need for someone to make an aftermarket ATX arm-rest that slides further back, See a need for it as it does improve the balance of my ATX. They would sell a bundle and make an additional part that fastens to the rear housing something that snaps over the headset connector portion and is secured with a small portion of the rear housing.

Anyway,  Don't think I'll be sharing this on any of the other forums, Unless I can word it so it doesn't discredit the ATX. Already Garrett has allot of issues with the ATX shafts and such wouldn't want to stir up the pot any more.

Wish I could post a pic,  Can email pictures but can't upload to Tinypic anymore. Having computer issues uploading being one of them.

As far a electromagnetic interference rejection at the spot in the above video then the ATX wins out on that compared to the very erratic threshold on the SDC2300.

You would hope before doing the test the tester pressed the Noise Cancel first to eliminate external interference.   

Here are the three major benefits of the breakthrough capability of the SDC2300.

Higher immunity to electromagnetic interference and thus quieter operation
Less noisy in the mineralised ground prevalent in most goldfield areas
Much more sensitive to detecting sub-gram nuggets
 
It appears to me in the video when using the dial to lower or raise the Sensitivity setting it not only lowers or raises the target response it also at the same time lowers or raises the electromagnetic interference.

The SDC runs extremely quiet in regards to mineralization, due to this the higher sensitivity settings sound to the ear like they have more instability (variation in threshold), however this is not quite the case as the instability is also partly due to the almost compete lack of ground signal response. I find the variation in the threshold takes about an hour to accustom your ear to on the higher sensitivity settings of the SDC, however it is still quite workable because it is consistent therefore easy to ignore. In the lower sensitivity settings the SDC still has excellent performance and is of course much quieter due to the lower Gain.

SDC 2300 high treshold hum can kill your head.... in few hours... on this video machine is much noiser than ATX... but I belive that is only treshold level adjustmen I think, isn't it?

      Well, coffee and tools in hand I got going with the fun part - taking stuff apart! Many photos in this thread will enlarge if you click on them.






      You can probably see where I am going with this. Circuit board in a box with single AA battery holder and control panel tacked outside with controls. All in one box that can be rod mounted or hip or chest mounted. If rod mounted, I want to be able to use stock DD coil, or Infinium 5" x 10" DD and 4" x 7" DD. Not willing to pop for another ATX 8" mono at this time as the one I have stays as it is to use with the other ATX I will be getting. We will see how this works out first.
      In theory I would like to do a real professional box with drop in battery, just like a White's TDI SL but the box would have to be longer. I may however go cruder than that, more like a Surf PI with a lid I need to open to replace batteries. Be nice to use rechargeables and rig to just plug detector in to charge it but again, I may not want to work that hard at it. Paul would do a bang up professional job. I am all about expediency myself.
      If anybody want to see a closeup of anything or has any questions about how this thing comes apart ask away. I know I had to go buy yet another stupid tool to remove the Torx security screws!

      Hi guys - I owned one of the first ATX units (actually 2 of them) and suffered from the coil cable issues.   Despite that, these machines produced 100+ gold rings for me (in the space of 1 year).
      Garrett was awesome and replaced the coils but they failed again (and again) and eventually I sold the machines and focused on the CTX and EXCALs (modded) and later the Equinox.  After selling the ATX I purchased the Whites BeachHunter TDI and to be honest, was less than impressed compared to my finds with the ATX of the past.  I deeply missed the two-tone audio of the ATX and the 8” mono in the water.  It was a deep machine (the TDI) but I had become used to the ATX.
      I noticed my finds ‘dropping off’ once the ATX was sold - and there was no ‘replacement’ PI that was readily available......
      So last week I came across a late 2018 ATX and picked that up for a very good price - shipping now!
      i will update you guys with regard the cable issue - I guess I am hoping the cable is in good nick and may be the later version?  
      I missed the ATX - despite its known flaws.  Roll on the courier!  The forums are certainly quiet on the ATX nowadays

      This was our first test with her out in the Mojave Desert, and all I can say it is very easy to walk about detecting with this one.  Firstly, there was no stooping over with a scoop to pick up bad targets with this detector, they were all the real thing! And GeoSense works amazingly well, love being able to go with her automatically and easily keeping up with wherever I detected, it was a breeze.  I've detected with others that were unwieldly and hard to control in the desert, but I can say this one is really something special.   We walked for a couple miles on the edge of a dry lake looking for meteorites and she really showed her stuff. She almost seemed to know her way over the salty ground, and picked up anything I threw at her.  She easily found nuggets of every size left behind by many others, and was very quiet and hardly made any noise anywhere I went, even in the most briny parts of the ground covered with white salt, underneath the buzzing high tension power lines that cross parts of the dry lake, and even going over hot rocks did not seem to bother her much.  She's quite a detector and we are finally really lucky to have one like this!  All I can say is wow, everyone should have one like this for detecting!

      June is a great detector dog, we rescued her from the pound, and one day I hope to find a GPX 6000 too. Happy April 1st!

      It is mind boggling that almost all my buddies and other  people  I see hunting or talk to have a Nox.The same thing could be said for the  Garrett At series.Almost everybody I know  has had one and I have seen guys  I don't know  using them a lot before the  Nox came out.With Garrett the At pro was the most common.On this  Forum  I would bet that most have had a Nox.  Even  though  I used the X-terra I never saw that many being used around here even though it seemed to  be  popular around the  world.The At  pro was more popular compared to it  in the US probably because of Garrett  marketing and it being all terrain and cheaper compared to the 705 version.For the turf I would take the X-terra any day because it    could be  tailored to more hunting  situations.The x-terra and the Nox sound very    alike which made it easy for me to gel  with the Nox.
