Garrett ATX Strip Down & Rebuild

Recommended Posts

Well, coffee and tools in hand I got going with the fun part - taking stuff apart! Click on these photos to see larger views.







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!

I want it and I want it now! Home Depot folding set for $10.00

So the coil. The rod assembly easily comes apart if you have the spanner wrench to take the cams apart, but the lowermost rod is glued to the stubby connector on the coil. I just cut it off with my Dremel tool.

I want the coil to mount in the center (like a coil should!) and I want to keep the scuff cover from collecting debris. I had a well used Commander 15" x 12" DD sitting around I would be lucky to sell for $90 so it became working parts. I cut the top out, again with the Dremel tool, then trimmed it up with tin snips. Looking good so far.

Gotta love the internet. Thirty minutes of Googling and I found a box I think will work for me at http://www.mcmelectronics.com/product/BUD-INDUSTRIES-CU-592-A-/28-8598 Converta Project Box - 2.5'' x 9.5'' x 5.0''


It is on the way.

Best buy in a rod kit - the White's Space Saver Rod Kit at https://www.whiteselectronics.com/product/space-saver-rod-kit/ They sell the whole assembly for less than some people charge for a lower rod alone! And it will work with any lower rod, like the Minelab compatible rob I will use for my FrankenCoil, or the Garrett rod I will use with the Infinium coils. The rod has detents to mount a box forward of the grip, or under arm. I plan on under arm for balance purposes. The box will dismount to hip mount or chest mount so I will mount D-rings for a harness or belt clip on the box.

Well, the hard part is done. Got the setup pretty well figured out, now I just need to put it all together. Waiting on the box mostly but I can finish up the coil in the meantime.

Here we go again Steve, looks familiar. Wonder if I will end up with this ATX some day when you get sick of it. Still have the mod GMT though no gold with it this year, only dredged gold, Bob

Hi Keith,

I thought about plastic but decided to go metal for better EMI resistance. Not sure if it will make a difference or not but with a PI it can't hurt.

Hi Bob,

How are you - good to hear from you. I miss everyone in Alaska. Not Alaska, just the folks that are still there.

I am not too sure why I am even doing this. I guess after all my bitching about the weight of the ATX it is a bit to prove a point. I really, really do think the ATX is a great prospecting machine held back by a housing inappropriate for the use. Great for water but desert? And I am not going all the way because done right the weird underwater connectors on the coils need to go. But now that I typed that I could get rid of the waterproof headphone connector and install a 1/4" jack.

I am sure you did not plan it Bob but thanks for getting that thought into my head!

Is a chest mount really the witches tit? I saw what you did with a GMT. Got me thinking if I should try a chest mount rig with my TDI Pro. Sounds like you may be on to something.

      friends I plan to buy a Garrett ATX. Steve, can you give me information about this detector? Is it worth buying or should I turn to another brand?

      This is weird.

      I did a bit of Google searching for posts in the last year to see if I could get a feel for how much use the Garrett ATX gets and what people are finding with it. Not much to see though. The Garrett Australia Facebook page has some gold nugget finds https://www.facebook.com/GarrettAustralia/
      The Findmall ATX Forum would have you thinking the ATX is strictly a beach detector Link deleted since Findmall Forum update broke all old links and other than that a few relic hunters out there using it.
      The ATX is one of my favorite detectors and quite a capable nugget detector, but after some early nugget detecting it now only gets used seriously as a beach and water detector. The problem is with ATX at $2120 and 6.9 lbs, limited coil selection, it is a tough machine to recommend for prospecting with a Minelab GPX 4500 running only $2699 at this time. I still consider the ATX to have been a missed opportunity. At $1699 in a lighter weight dry land package and sporting less expensive dry land coils the machine could have made a real impact on the prospecting world. Instead it is a rare sight on the goldfields.

      I consider myself fortunate to have met Garrett's Senior Design Engineer, Brent Weaver, many years ago during prototype testing of the Garrett Infinium. I think Brent deserves a great deal of credit in making Garrett the leader it is today with a series of incredible innovative bang-for-the-buck metal detectors, first and foremost being the AT series. Brent is just a real nice guy - comes across as a regular Joe not a head in the clouds engineer. I think this video shows that. It also has an extremely interesting discussion of pulse inductions detectors, ground balancing methods, and the dreaded "hole" that occurs when ground balancing. There is explanation of why the holes occur and how some designs try to alleviate but not eliminate the problem. Good stuff, starts around the 3:40 minute mark.
      The audio quality in this video truly sucks. However, this is important information, and so repeated listens, typing, and listening again on my part produced the following transcript. Again, this is from Brent Weaver, Senior Design Engineer, Garrett Metal Detectors
      Transcript starting at 3:40 mark:
      "If you look at the various pulse detectors that exist on the market, you have your simplest pulse machines, which are single pulse machines that are non-ground balancing. Those are detectors that are typically exclusively used for the beach, for example, the Sea Hunter or something like this.
      The next step in advancement there is to have a ground balancing pulse machine, those can still be a single pulse detector. This pulse channel is able to ground balance, which means it can neutralize the ground. The problem with that sort of technology is when you ground balance out the ground, you can also balance out any target that has a decay characteristic that is similar to the ground. We call this the "detection hole". Essentially, it is a hole in the conductivity... when you look at the conductivity of gold or any material, you look at a conductivity spectrum. The decay rate of that... pulse decay is a function of the conductivity of the material and also the thickness and shape of the material. It all factors into effective conductivity.
      For a ground balancing pulse detector, again, if the conductivity of the ground is similar to the conductivity of the target, when you ground balance out the ground you also ground balance out the target. To eliminate that problem, you create a second pulse which is substantially different than the first pulse, such that when you ground balance out the ground on the second pulse, its conductivity decay as far as the target is concerned, the conductivity decay on the first pulse and that on the on the second pulse do not match each other. As a result, as you ground balance out the ground on the first pulse, you create a hole, and you ground balance out the ground on the second pulse, it also creates a hole, but it is in a different location.
      And so, those two pulses working together in unison, working simultaneously, one will always fill in the hole of the other, they overlap such that you never have a detection hole. If you only have a single pulse detector, and it ground balances, it will have a detection hole. There are various products on the market, some are less expensive than the ATX, some are more expensive than the ATX, but if they are a single pulse detector, they are going to have a hole in their detection, period. You are going to miss gold. You are absolutely going to miss gold.
      Now where that hole falls depends on the mineralization conditions, and where the ground balance is set for the detector. As the ground balance shifts, the hole shifts with it. If you have a detector that has continuous ground tracking, such that you cannot switch it off, as that ground track moves around for the various ground conditions, the hole moves around with it and the targets are disappearing into that hole. You never know where the hole is at any time.
      Again, to eliminate that problem, the more advanced, the most advanced detectors, like the ATX, use multiple pulse technology. They don't just have one single pulse that repeats, they have different kinds of pulses, and those pairs repeat. That is one of the differences in a true high end performance product like the ATX, versus some of the other products on the market. They are good products, and they are ground balancing pulse detectors, but if they are a single pulse technology, they have a hole in their detection that will miss targets."
      Now, for me listening to that it is obvious that Garrett was clearly gunning for the White's TDI. How do I know that? Because it was Minelab that originally put multi period pulse detection into the consumers hands, via their MPS (multi period sensing) technology beginning with the ground breaking SD 2000. The White's TDI on the other hand is an older design, and in fact is basically just an Eric Foster Goldscan stuck in a White's labeled box. The Goldscan and the TDI are a single channel ground balancing pulse detector with the problem that Brent outlines in the video. Bruce Candy of Minelab saw the same issue and the SD 2000 was specifically developed as a multi channel or multi period device for this very reason.
      MPS was patented, and so I am not sure if it was the patent expiring or Garrett simply using a method that got around the patent, but the ATX is using a similar multi period design as the SD Minelabs. Having used the Minelabs and the TDI plus the ATX I can vouch for the electronics in the ATX as being very capable and I do believe superior to that in the TDI. My ATX in fact tested favorably compared to my GPX 5000 with the 5000 having the edge, but not as much as I expected. I think in large part that is simply due to the Minelab using a much more powerful battery pumping far more power into the ground than the ATX with its eight AA batteries.
      Unfortunately in my opinion Garrett made a huge mistake in taking these excellent electronics and hobbling them with a housing that did not take advantage of one of Minelabs biggest weaknesses - ergonomics. The TDI had and still has a distinct edge in that regard, and at a lower price than the ATX. Ironically, it is also that detection hole and the ability to manipulate it via a manual ground balance that has become, not the big problem as laid out in this video, but a feature of sorts in favor of the TDI. People have learned how to manipulate the hole to help identify targets by using the ground balance control as a sort of reverse discrimination control. Combined with the unique conductivity switch on the TDI knowledgeable users can become very proficient at identifying various target classes, and this has made it very popular with relic hunters in particular.
      What history in hindsight reveals, in my opinion, is that Garrett missed the boat with the ATX as regards Minelab. The ATX hit the market before the SDC 2300 and had a window of opportunity to really make inroads if it had been in a lighter weight dry land package with a light dry land coil set designed specifically for desert prospecting. The electronics are there; it is the heavy housing, and heavy knock sensitive coils overpriced by an attached telescoping rod assembly that really hurt the machine. On the flip side, I don't think they did too much damage to the TDI also with the TDI being a less expensive more ergonomically friendly unit. Like the Garrett Infinium before it, the ATX has settled into being more a beach detector than a prospecting detector.
      I have of course been making hay over this since day one and continue to make an issue of it at every opportunity in hopes that we may see a Garrett LTX some day. Dry land design only for the absolute lightest weight possible machine with light weight knock resistant coils to match, it would be a winner. There is a market still I believe for a $1500 -$2000 ground balancing PI detector that clearly has more power than a TDI in an all in one package lighter than anything Minelab currently markets. The only question in my mind is whether Garrett will finally get it right or will it finally be a moot point when new Fisher, White's, and Nokta/Makro machines waiting in the wings finally arrive.

      Hi Guys!
      When i bought my ATX i bought a Grey Ghost amphibian as well.Fist day in the saltwater after an hour i notice an strange rosty colour spreading all over the back of the detector where the speaker is located.I just got panicked and cancled the hunt immidiately.When i got home i noticed the round edge of the speaker which is metal is rosted as hell!!! I looked around and could'nt find the problem.When i unplugged the headphones i realised that in the Grey ghost package there is some o-rings that i supposed to put it myself on the connector.THAT was the problem!!! i put the o-ring on and problem solved.But my speaker was så rusty i put some silicone glue all over it to isolate it from saltwater.I should send it to Garret which i did'nt. It works ok since then but i think there has been a slightly current without the o-ring that makes the speaker rust.What do you tink guys?

      From page 27 of the Garrett ATX Owners Manual:

      "Coil covers: Use a coil cover to protect the coil from abrasion and damage and prevent false responses that may occur when the coil abruptly impacts a rigid object such as a large rock, etc."

      I agree, especially when coils have an MSRP over $500, that you want to protect them. Nugget detecting in particular subjects coils to a lot of abrasion and hard knocks.

      Standard Garrett ATX Searchcoil
      10" x 12" (25 x 31cm) DD Coil
      Part Number 2234600.....$529.95

      Optional Garrett ATX Searchcoil
      8" (20cm) Mono Coil
      Part Number 2234000.....$529.95
      Excellent depth on small targets. Enhanced maneuverability in heavy scrub and tight areas.

      Optional Garrett ATX Searchcoil
      Deepseeker® 15" x 20" (38 x 50cm) Mono Coil
      Part Number 2234100.....$599.95
      Use for locating larger and more deeply buried objects. Includes surface debris elimination.

      Garrett has been playing catch up, as even existing coils like the round 8" mono do not have a scuff cover available yet. Still, Garrett is on it, and at least two coils are now being made for the stock DD coil, a closed and an open scuff cover. Here is a picture of them but I have not been able to find part numbers yet. Hopefully Ken or one of the other dealers can chime in with part numbers and pricing.

      Scuff covers for Garrett ATX 10" x 12" DD Coil

      For those of you without a scuff cover do not be overly concerned. I have been using my ATX full bore without scuff covers and the end result is that the bottoms of the coils are scuffed and lightly abraded. My 8" mono in particular got a hard go of it in Hawaii. The epoxy bottom is tough and it will take a lot of use to have an appreciable effect so I would not worry too much about it from a service aspect. The main concern is when you go to sell the detector, a scuff cover means the coils look closer to new than well used. They are a good investment for that reason alone in maintaining the resale value of the detector.
