QXT Pro question

Looks like the QXT PRO is a upgraded QXT

Whites said back in the day that the "Pro" version was a name change only, and that it was identical to the regular QXT, to go along with the name for things like the 6000 Pro XL and such. However, I'ved owned several regular QXTs, and also several QXT Pros, and while the software seemed identical (I never checked the software version # to see), I found the Pro allowed the sensitivity to go up to 18 instead of the usual 16 and still be stable. Now, whether that was just a slight change in the scaling #s for the sensitivity setting software wise, or whether it was the fact that the Pro had slightly less EMI generation and thus further stability at higher gain settings...Nobody knows I don't think. I suspect though that the Pro, while it may have had identical electronics inside, might have had updated versions of those parts, which as time goes by usually means more tight tolerances and less EMI generation on a circuit board. That's probably why they couldn't technically claim it was an updated QXT, but in reality it did have slightly higher performance.
Now, far as the name on a "Pro" model, I believe if you send an older QXT in for a software update (the original software read 1c to $1 in the COIN zone and have trouble with ground balancing in some soils, as where the newer version read "COINS" on the screen and fixed the problem)...I think if you send in a QXT with older software for the latest upgrade, or even send in a QII to have it's software upgraded so that it's a QXT now (only difference between them was the software and the coil it came with)...I think Whites gives you "QXT Pro" stickers for the control box. I know at least that if you upgraded a QII to a QXT you got QXT stickers. The upgrade for a QII is worth it, because the QXT version has assignable tone alerts where I don't think you could do that on the QII I used to own years ago. I think the QII also lacks the ability to turn off noise reduction, which is one of the keys to extreme depth with the Quantum.
At least when I sent a QXT in to get the software upgraded, the price was very reasonable if I remember right and well worth it. I'm not sure if there have been further upgrades in software from the newer version of the QXT to the QXT Pro, or if they've even upgraded it more over the years, so I would read the version # on your Quantum when it powers up and then call Whites and ask what the latest version # is. I'd love to see them change the software to show a VDI # for targets based on conductivity. If that was done it would breath new life into those machines and make them an attractive option for say gold ring hunters who want to split hairs on targets more than you can with the 8 zones. They could keep all as it is now with the 8 zones, but just provide a VDI # as well on the screen. Seems like an easy software fix IMO. Too bad some tech savy detectorist out there couldn't hack the software and provide the upgrade to it.

Critterhunter has posted lots of info on this particular Whites model on this Forum and a site called JB's it would behoove you to check it out. I recently bought one and am on the learning curve. They are a well made, beautiful detector they provide 8 zones of target info much like the CZ's with 7 zones on a meter.
Everything I've read and heard would indicate the QXT is a real sleeper. I paid a little over $200 and feel it was a tremendous bargain.

I just bought a QXT for get this $60 
I have been researching it for 2 days now and unfortunately I cant seem to locate the quantum tips from JB's site? I have only found 1 link that was dead. Is there any chance anyone has a link to it? I would really appreciate it and your knowledge on the machine.
Thanks in advance

Hi all, I was reading this thread and I too own a Whites Quauntum 2 that I bought last November for $80.00. I went to check the two site's that I have saved of JB's site and now they are gone but I have another site that might be helpful, it's a review page for the QXT.

I am also a qxt pro owner myself. I don't how many of these detectors are still hanging around out there but I am kind of proud to own one of whites most controversial detectors ever made. I say that because they were not made for a lengthy time and they had a love/hate relationship with people. I love mine. I bought it when Whites put them on clearance and discontinued it. I am glad to see some posts back on the internet regarding this model.
