I used the DFX and absolutely enjoyed that box to the fullest. Held on to it until 2 weeks ago(after having used the V3 for over a year and it was a machine that took me awhile to get good with.....I missed my XLT for a bit too.
Like many here, I've developed a good relationship with a lot of people in our hobby. My dealer has become a good friend who occasionally has me check out a machine to see how they are performing in the field with the new owner or just the machine itself. This usually turns into a hunt and mini class for both me and the individual or a hunt all by my lonesome. (Both only a good thing!)
When doing this, I get to meet people who are everything from a beginner to someone who shows up with every model of machine bristling from their rig like a porcupine! (This has been a blast to check stuff out and have mostly met some great people.) Within this last year I've seen lots of machines to say the least, and with only one exception, had machines tuned to an individual and the owner walking away doing very well and at least having a higher level of confidence to get the job done for themselves. In all these machines, only one had a bad coil and had it swapped out within 15 minutes. Checked out other top brands and never found a fundamental issue with those either.
My last two times out with folks have been with the most opposite types possible. The first gentleman had problem of not getting stability and depth. He was a bit of a difficult person to teach as he had some "original" bad concepts of how a metal detector works. It was one heck of a lot of work, to even get started with showing him, so I just said "Give me thing." and did a solid programming for coin/jewelry with 4 tones, VCO and fast recovery. I began doing a jewelry only hunt and he gravitated to primarily coin. He found nickels like nobody's business and lots of deep clad. I found masses of "good" aluminum. Towards the end of our time, he came back to the "learning table" and wanted to know what I'd adjusted. Told him. He understood it all and adjusted it to even better settings for what he wanted to do. (Felt good for me!)
Other guy is a carpenter who was way mechanically inclined. Completely new to detecting and only gave him a "crash" explanation (two weeks ago) over the top of his table saw.Yesterday he walks in to my work holding an 1884-0 Silver Dollar he'd found!
It was my lunch time so him and I went to a place to eat and talked detecting and adjustments. He didn't know much about detecting but he knew how to build stuff and had "built" programs like crazy. Found one that worked fine and was kicking butt in an old (forgotten) country club! Told him what to think about when adjusting with recovery,filters and the RX/Disc. balance thing. (His initial "problem" wasn't depth but stability and suspected the coil due to internet postings!) Before we got up from lunch, he'd already worked up a good program for what he wanted to achieve and I have no doubt he'll do well. (I was tempted to ask him if I could go along next time, but decided not to ask. (He earned his "own" glory hunt for sure!) I hope later he'll be up for a hunting partner on this site!
My experience has been that not many machines have an issue and internet postings are not at all what realities are. Don't get into a "nervous ninny" mode and not buy this machine. It truly rocks!!!! Scott
