Help Gpx Or Atx

Recommended Posts

Greetings friends, I want to ask a question and I hope you can help, he is long after an garrett atx, but I have the opportunity to buy a gpx 4800 with several coils and batteries, where I am not sure if there are nuggets, what that if I know that there are many coins and jewels, even vessels with coins inside the planting grounds, my question is the minelab gpx 4800, could it be useful for this type of search (buried treasures) or is it only for nuggets and small things? What is more convenient if I look in sowing lands and walls of old houses? Gpx or atx

It will detect coins and relics no problems, it detects all metals.... the problem is the discrimination, it has some basic iron discrimination but it's nothing like swinging a VLF detector with target ID's.

It will no doubt detect coins and treasures deeper than a VLF in a lot of cases but you'll be digging a LOT of junk. 

If you're primarily after coins and jewels like rings and so on, a VLF like the Minelab Equonox is your best bet in my opinion, cheaper too.

If it was me I would go for the ML4800 a great detector, and get a cheap VLF. machine for playing with coin and chase the gold with the ML4800. If you are after deep coins then use the ML4800 and dig every thing, even leaving known junk will mask good deep signals. You don't have to use ID to get good finds but it does prevent you from walking away from junk infested areas.

The Garrett ATX and ML 4800 (GPX) use similar pulse induction (PI) technology and both can be used for natural gold detecting or for relics and coins.  It is somewhat difficult to advise you as I am not sure of your experience level in detecting and what kind of soils you will be primarily detecting in.  Sounds like ploughed fields.  Unless the "treasures" are super deep or the soil conditions are challenging with lots of iron oxide mineralization, a PI detector may not be necessary, and a less expensive VLF induction balance machine might be more suitable to your circumstance (more about that later).

The ATX has the advantage of being fully waterproof which means you can use it in the water or in foul weather without having to provide additional protection to the control box.  The ML 4800 has better iron discrimination circuits than the ATX, is lighter, and the timings are more sophisticated for varying soil conditions which is really just an advantage for gold hunting.  There are more accessory coil options for the ML 4800 than for the ATX.

Since both use pulse induction technology, they will go deeper than your typical VLF induction balance detector which are more commonly used by those seeking coins and relics and are typically much less expensive than the ATX and ML GPX you are considering, unless the price is highly discounted because the unit is used.  If you are seeking deep buried caches of treasure, I would lean towards the ML 4800 because its audio tends to give you a better "picture" of larger, deeper targets.  

If this is a hobby you are just embarking on, I highly recommend taking the advice of others here, and start out with a capable VLF machine like the Equinox 800.  It is highly versatile and light weight and is simpler to operate and tune than a PI detector and if you find that the hobby is not something you want to pursue your investment is relatively small.  It will perform well in all kinds of tough soil environments such as salt beaches and highly mineralized soils (where PI detectors also excel) If you really want to just dip your toe in the water with a capable detector with minimal investment, I recommend that you investigate using the Nokta Simplex detector.   Which has just been released (so it may be difficult to find initially).  It is low cost but appears to be very capable and straight forward to operate.

Good luck.

The Garrett ATX and Minelab GPX 4800 have similar capabilities, and unless I needed the detector to be waterproof (ATX) my choice would be the GPX 4800. It has more power, more tuning options, and vastly more coil options at better prices.

I know a person who bought both of those detectors.  He favors the GPX for gold hunting and found the ATX to be a little too bump sensitive.  But that is all second hand info.  I wish I could give you better.

      Hi all,
      I'm from France, working with a GPX4500 of 2003.
      Yesterday when I started this old guy, I was affraid by this problem :
      - Sound when the treshold start is strange.
      - The autotune (research for free frequency) is a stable sound, with no variation.
      - And no power ! about 5 inch max for my metal digging pickaxe.
      I tried some factory resets, but the problem is always the same...
      I tried this one with another disc, trakking button, cable, headphone, battery, the problem come from the main box...
      Anyone knows this problem ?
      Thank you and have a nice day.

      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?

      Hi guys I'm back after laying low after my nugget find starting to get back into some detecting again.. Still been using my 24k vlf and no way I'd get rid of it its so good.. But I am in need to replace my gpx I sold.. And I can't decide whether to get a gpz and run the small  xcoil soon as it's available to buy.. Or run with a gpx 5000 and get my trustie Sadie coil again.. Aparently my gpx I sold ended up with moisture damage on points but was fixed easy but with living on the wet west coast I'm thinking the gpz with its wetherproof housing might be better but the big coil isn't practical for alot what I do creeks bedrock etc but is for old tailings piles.. 
      I was wondering maybe Steve or kiwijw might he able to awnser this how small will the gpz detect will it go as small as say sdc in low to mild ground 
      And 2 is the depth over gpx noticeable on smaller gold 
      Thanks Craig

      Yesterday I took Calgeologist out to my claim for a few pointers on his new to him GPX5000. I think he had already memorized the owners manual and read everything he could from a few forums.  That made it easy as there was not much more for me to do. I had him hook up an external speaker and walked with him for advice on various targets and sounds.  He chose to use the Commander 12x15 Mono, a bit of an overkill but he did not have any smaller mono coils in his arsenal.  After awhile I let him go on his own and started my own hunt.  An hour later he came up to me and asked for some help, by then I had switched to my new GB Pro after beating the skunk away with the GPX.  He told me he had gotten a target out of his dig hole and asked me if I could help end his frustration and point it out for him. He pointed to the spot he figured it was and bingo the GB said he was correct.  I got a mild signal and had the target in my scoop.  It gave a nice signal on the front sensitive portion of his monster coil and when I spotted his target after a few cuts I was totally blown away... I mean it was unbelievable.  He found a small birdshot a few inches deep.  He was hunting in sharp timing, slow motion and I think quiet with the gain set higher than factory setting. Can't remember his gain setting for sure.  Just amazing the sensitivity of that coil...... and he did not even have it in Fine Gold timing! 
      If some one told me they could find birdshot with that coil I would be pulling on my extra high Bshort boots!  I also think nuggets are in serious trouble when he gets a bit more experience under his belt.

      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.

      The weather here hasn't been very summer like, while Australia is having heatwaves and severe bush fires we've been wet, with regular snowfall.  The lake levels are at crisis point where the nearby towns are close to getting flooding.  The rivers and creeks are all roaring with water washing around some nice flood gold 🙂  
      JW and I decided we'd go prospecting yesterday for a bit of fun, we went to one of our old haunts, we've done this area and this particular spot so many times and every time we think it's hunted out however JW's 10" X-coil got a fair few bits there last weekend and this weekend he was going to try the 12" X-coil to see how it goes there.  It was raining heavy at my place when I left and JW's house was also meant to rain all day but this particular spot we were going to the mountains were meant to keep the rain at bay.
      Here is a little video of a Dam we drove past showing the flood gates open due to all of the rain, where I was standing filming it I was getting wet from the mist of the water
      I didn't notice at the time but if you look hard you'll see two people in yellow jackets standing down at the base of the dam having a shower in the water 🙂
      I went not expecting to find anything but I just enjoy the hunt anyway and as it goes with gold, you never know.  I wanted to try out the 12x6" X-coil on the GPX 4500 as I've never used that combination at the spot and I've mainly used my QED lately so the GPX is getting dusty.  The reason this area is such a challenge for the GPX is the massive high voltage power lines that run through it, they're connected to the Hydro Dam and with all the flooding going on they must be really pumping out the electricity.  As I've mentioned in the past the QED handles the power lines fine at this spot although it is very sensitive and I do spend a large part of my day digging shotgun pellets when using the QED here.  I am sure a KQED-spert could tell me ways to get around that, maybe changing my mode from Mode 1 to one of the higher less sensitive modes would probably work.  It's the reason I don't like using VLF's here too, pellets... pellets.... pellets 😞
      When we arrived I strapped myself up with the GPX, all my cords and harness were in a big tangle and fired it up and no audio, bugger! did I forget a cable.  In a massive panic I went back to my backpack and searched for a missing cable.  It turns out all I'd forgotten to do was plug the speakers into the Steelphase SP01, I'd plugged the SP01 into itself with a loop of the cord 🙂  It shows how long it's been since I've used my GPX, forgot how to plug all the cords in.  I really like not having all these cords and harness with the QED.
      I've run the GPX at this spot a number of times and it has found me gold, prior to getting any X-coils I used to use my 14x9" Evo here, I had to have the gain quite low and audio in Quiet to get it semi stable but it never really ran nicely, I was never able to get a smooth threshold.  I have one of the early Australian made GPX's which I believe were a bit more noisy than the modern ones too which doesn't help.
      There are lots of old tailings piles at the spot, most aren't worth detecting as they're just big rocks, and the ones that are worth detecting have been pounded by every man and their dog, including myself and JW many times.

      Someone had dug a massive hole, it looked quite fresh, It looked at least 15 inches deep and all they got was a rusty bit of metal that they'd left beside their hole!

      The little 12x6" X-coil was working quite well on the GPX considering the power lines, It had a bit of pulsing but the threshold was mostly pretty good considering, I had my gain on 12 most of the day in sensitive extra with audio in boost and was pretty happy with how it was running, a stark contrast to when I used the EVO here I had to keep my gain down at 8 with audio in Quiet and it was still noisy.   It's always my go to coil for high EMI areas, the smaller size and I guess whatever else the manufacturer has done has made it a pretty good coil for EMI.
      I was struggling to find any good targets though, it was only probably 10 minutes after we first arrived that JW came over to show me his first bit of gold so I knew there just had to be some gold left here.  I can't expect to come close to his GPZ + small X-coils though, there is no better combination in my mind for finding these small gold bits at depth.

      Here is a photo of the dirty great big power lines with all that flood power running through them 🙂  The weather held up mostly well for the day, a few showers, a few minutes of hail but mostly sunny.

      It kept getting a signal on this big rock, it's loaded with quartz in lines through it, hitting it with my pick did very little so I gave up on it.  The photo doesn't show the size of it, it was three times bigger  than I am 🙂
      Seeing I was desperate to find some gold at this spot and didn't have much hope for myself I resorted to my usual tactic of flipping big rocks over, it's worked here in the past.  I guess those who have detected the ground before me didn't do it and the rocks added enough depth that they missed the gold under them. 

      I was regularly finding these little skinks living under rocks,  I believe they're rare and endangered so I was always very careful not to injure any of them.
      I flipped over this massive rock and a spider ran up my arm and under my t-shirt sleeve, I panicked and shook my arm and brushed at it to knock it off.  A side effect of living most of my life in Australia is a fear of spiders, NZ doesn't really have that issue and poison or dangerous wild life aren't really something you concern yourself with however the Australian in me kicked in and I wanted to get it off me quick smart.  I did that and looked down expecting a little harmless NZ spider and to my surprise it was an Australian Red Back Spider (Australian black widow).  A Deadly venomous  sucker that could have killed me and it was the biggest one I've seen in my life.  We used to see them quite a bit in Australia but I never expected to see one here.  It's a shame I didn't put something next to it for scale to show just how big it was

      Shortly after this photo I introduced it to my foot.  After doing some research it turns out they do live in the area and they're trying to get rid of them as they're an invasive species that came in from Australia, I am surprised they survive the winters, the grounds often frozen solid here in winter.
      After my scare I decided I'd stop flipping rocks and started detecting the cracks in the bedrock.  The grass growth from all the recent rainfall has made life difficult too, normally this place is dry and brown.

      I found a good area of bedrock and detected along various cracks in it, ones that didn't have too much grass and found my first bit of gold for the day.

      A little guy but a real screaming signal.  I was never going to miss this one, it sounded like a 22 shell does.

      .247 of a gram!  Quite big for me lately 🙂
      I checked that spot a lot after that hoping for more, I even dug more soil out of the crack and checked it hoping there was another undetectable bit deeper but I was all out of luck so I moved further down the crack and had target, very faint, not a screamer like the previous one but sure enough another bit of gold.

      This one was quite deep down in that little crack there

      It looks about the same size but it's very thin, not much to it.

      0.103 of a gram. 
      Here is a little video showing when I get them, it also shows there is no knock sensitivity of the 12x6" X-coil even with my gain up high seeing this question is often asked about various X-coils.
      I kept hunting around but found no more gold for the day unfortunately.

      Someone went to a lot of effort to prop this big rock up, I checked under it but nothing.
      I later switched to the 15x10" X-coil but I had to lower my gain down a fair bit as it was being messed with by the power lines, I knew it would be as my 14x9" Evo is terrible here and it's even bigger.
      I also found some weird sheltered spot under some rocks where it looks like some crazy wild animal has been living bringing back the bodies of it's victims.  After my Redback discovery I thought this could be anything, maybe an African lion or the elusive Bigfoot so I took off quickly.

      I didn't want to join the bones 🙂
      And that was it for the day, 2 for me for a total of .35 of a gram.  KFC time!
