Jason, I am suggesting there could be two voltage regulation circuits in the CTX. One that handles the rechargeable and another that handles the alkaline pack. The detector has to know which type is attached for the battery level meter to be accurate and there could be other reasons like for efficiency.

No, there is zero need for multiple voltage circuits. The detector doesnt know what pack is connected, and there would be no reason to. Voltage is voltage, the detector doesnt care if its coming from an alkaline cell or NiMH or lithium cell. All the detector cares about is enough voltage to operate the circuits.

Mattysiam, just try to borrow a rechageable pack and try it. You are going to want one anyway so maybe just buy one.
Jason, why argue about something that you don’t have a schematic for? The battery voltage range of the two battery options are 1.5X difference and the discharge curves are different because of the battery type. The detector does “know” what’s attached. I’m not saying there couldn’t be a shared regulation circuit but am saying there are reasons to have separate ones.

I'm "arguing" because, according to your "theory" the detector wont work correctly if it doesn't know what type of battery is powering it, and that is absolutely ridiculous. According to you, if we put rechargeable AAs in the AA holder, it shouldn't work, but they work great. Doesnt matter if the batteries are Alkalines, zincs, Nmh, NiCad, or plutonium. The only thing that matter is that battery power is greater than power need. Period, end of story.

The detector doesn't need 13v from a full Alkaline pack. It likely needs 6 or 7 volts. Everything above that in the battery pack is just more reserves. My GPZ pack is amazing in my CTX and it was WAY more power than either factory pack AND its an authorized power supply.

The GPZ pack is twice the current capability as the standard CTX pack. That’s fine, still has the same discharge curve - the battery meter will work the same. In fact there could be a Coulomb counter measuring chip in the pack itself. When my original pack died I rebuilt it with 3A cells. Works fine.
I am not saying rechargeable cells won’t work in the alkaline pack(!)
The discharge curve would be different but the detector obviously works. His detector is not working well and I am suggesting the experience using the rechargeable pack may be different. It would still indicate a defective detector as the alkaline pack should work.
In my experience if the detector comes up and operates the power source is sufficient. If you get bogus setting changes the internal 3v battery may be low.
If you get poor depth or high EMI I’d suspect the coil or coil wiring. Agree?

Update: I contacted Minelab in Malaysia, my nearest service centre. The Coiltek 10x5 coil I was expecting on the 23rd from a friend from the UK, was accidentally forgotten and left in Scotland, so I can’t test the CTX with a different coil for now. Minelab in KL told me yesterday my machine is no longer under warranty. They have my serial numbers for the machine and coil, and also my purchase receipts from 6th September 2018. They are investigating the warranty issue with Minelab AU. I’m waiting for an update on this.

Can someone confirm please that Minelab offer a 3 year warranty? Hopefully Minelab AU will sort this additional problem out for me. My plans to buy an EQ 800 for the Mrs are currently on hold.

Will update again later.

Matt...My only thought is that the seller sold you a used machine and the entire deal is “funny”. 3 year warranty is standard,I believe 1 year on coil and battery stuff. You have a sketchy seller OR it was listed as “used” and you didn’t catch it. Let us know...

Did ML confirm that they will even service a detector from a different zone? That was my biggest concern in all this. I remember an incident years ago where someone was selling a group of Spanish E-Tracs in the USA. Someone called ML and asked to make sure the SN was legit and was told that they cant service it. All warranty work must be done in the region the detector originally sold from. Is that what your service center meant by it not being under warranty?

If it ends up truly out of warranty I’d suggest checking the internal battery. See the “hacking the CTX” thread. Mine has gone dead twice. It’s rare as the service center doesn’t see this problem often. But will show in old detectors that sat for a long time before being used. You see all sorts of weird behavior that just gets worse. If you can find something called de-oxit you could try it on connector and battery contacts. Were you hunting underwater?
Did you try reloading firmware - yours might even be down level anyway. Worth a shot.

To add quickly to the above,Deoxit can be found at a “Radio Shack type” place. Not sure if Radio Shack made it to Phuket...:smile: But!...they sure seemed to make it to everywhere else.

The vendor seems 100% legit to me. It was listed as brand new, and from the state it arrived in it was brand new, no question. If anyone wants the link of where I bought it online in the UK. send me an email and I'll reply with info, I don't think I'm allowed to post it under this thread.

Still waiting for Minelab AU to look into the warranty issue for me. I'd be surprised if they come back and tell me it's no longer under warranty.

Re the firmware, I'll check it this evening if I get time, it's high season now where I am and my business is taking all the spare hours I have right now. I don't have access to a windows machine, and last time I checked Xchange was only available for Windows. I have Macs at home, at work, and it's weird, but everyone I know has a Mac. Still, I can still update the firmware I think, but without Xchange. I will also check the "Hacking the CTX" thread. Thanks for all the info and advice.

Not sure you can update the firmware on a Mac unless the Mac has a version of Windows loaded using Bootcamp or Parallels!

I installed windows on one of my Macs with Bootcamp and can now use Xchange2. Now I remember why I switched to Mac about 15 years ago! Anyway, the machine has the current firmware installed.

Update: Issue is still ongoing and dragging on and on.

My local Authorised Minelab Service Centre is in KL, Malaysia. The email replies from them have been patchy at best, and often only after I send follow up emails as there's been no response. They are very polite though. I first contacted them on 19th November. Yesterday (03rd December) I was told yes, my CTX and the coil are under warranty, and then suggested I send it to Minelab in Australia. That's like two weeks it's taken to be told that.

Still haven't been able to test with another coil. I've been trying hard to buy the 17" CTX coil, but, Minelab won't ship to Thailand via Amazon, and I spoke with a Thailand reseller last week, and five days later I'm still waiting for prices for the 17" coil for the CTX, the rechargeable battery and charger for the CTX, and also an Equinox 800 I want to get for the Mrs. The supposed delivery date for all this was Friday 7th December, but was told today it isn't gonna happen.

It seems although I'm really trying hard, it's impossible to give Minelab my money, because I live in Thailand.

My next email is to Minelab Australia, to see how I go about sending them the CTX and coil. Do I have to pay for the shipping to Australia? Questions like that.

Matt...the way it should work is this. Since the machine is under warranty,ML should send you an RMA(Return Merchandise Authorization) slip and you use that as your shipping label,no money out of pocket necessary. Odd that ML is so slow to service Thailand,as I had thought for some reason that some of it’s manufacturing was done there...but I could be wrong about that. Time to get on the PHONE,ask to speak to someone who knows English very well,and explain that the machine seems to be malfunctioning and needs service IMMEDIATELY. This has gone on too long already and should’ve been resolved some time ago...

Matt,
I don't have a dog in this fight but I purchased my CTX3030 brand new from a dealer in Georgia. I live in South Carolina. Came with stock coil, WM10, Minelab
Battery Pack, Head Phones, and a empty battery pack to use over the counter AA batteries for which I have been using rechargeables. I later bought the huge
17" coil (I think that's the size) and the small coil at a different time used in very trashy areas. That small coil would not "communicate" with my machine.
I called the dealer in Georgia where I bought my detector and the coil and he sent me a brand new small coil to replace it. Never asked me for the original one
back and I still have it and it still does not work but replacement did. Paid $1500.00 for everything but the 2 extra coils, including some other goodies I did not
mention. That was in 2015. Yesterday my machine started doing everything yours is doing, exactly. I looked and my battery was in the red just before shutting
down. It was all over the place. Went back to the truck and got some fresh rechargeables and back to digging with no issues. It sounds to me like it's one of
2 things. Either you have picked up some flakes of rust in your coil cover or something is happening to your voltage from the battery box to the head. I know
from my experience yesterday that mine was all over the place and I couldn't pinpoint nothing, the numbers were jumping everywhere even over good targets
because I went back and dug them up after installing the fresh batteries. Had mine now for 4 years and no issue with it other than the bad coil which was
replaced free of charge.
Good luck
Glenn

Maybe it's just me, but if the machine is faulty then why not deal directly with the @#$%& seller?

I suspect that if they are a dealer (as you kind of indicated), that they would look after you. If they don't, then I would try and deal with @#$%& directly for some help........although it could be too long ago now??

Failing that, I would be all over ML to get this sorted out right away. If this is a legit purchase (sold as new warranted as new) then you shouldn't be getting the run around that you are.

I hope the problem gets resolved quickly for you. The CTX is a great machine, and you are just wasting time on what should be a simple fix (in my opinion).

Good luck.
