I have also HAD two MXT's, but I HAVE my third ... and FINAL ... MXT. Until something better comes along, this one stays!
Here are some points that I took into consideration:
<STRONG>Backlight for night hunting:</STRONG> ►DFX .. MXT
NOTE: I use my XLT for those applications as I have had much smoother performance from the XLT's than the DFX's.
<STRONG>AutoTrac®:</STRONG> DFX .. ►MXT
NOTE: I usually lock the GB on my XLT as well as my MXT, but the MXT has the continuous tracking and monitoring and an "instant update" of the GB setting at a flip of the toggle.
<STRONG>Ground Phase Reading:</STRONG> DFX .. ►MXT
NOTE: It works more accurately and faster than the XLT or DFX.
<STRONG>Ease of Use/Quick Control Adjustment:</STRONG> DFX ... ►MXT
NOTE: That's a strength of both the MXT & XL Pro
<STRONG>Audio Tone ID:</STRONG> ►DFX .. MXT
NOTE: I have this function available on the XLT, and I do use it on occasion. However, I prefer NO Tone ID most of the time.
I am sure I could figure out a few more things to note, but ... what I found when I had each of the DFX models was that IN MY BAD GROUND they just didn't work as well as other models I evanluated side-by-side. I used a few competitor's models that worked better in the types of sites I usually hunt than did the first two DFX's. I had much better performance and less falsing and 'noise' in the very iron infested sites with my XL Pro and XLT than I did with the DFX.
I sold or traded them off and when the MXT came out I got one. I liked both of the first two MXT's, and only parted with them due to medical expenses at the time.
Earlier this year I bought a brand new DFX thinking that, maybe, the first ones that I had were not working right and wanting to give the DFX one final try. I had the DFX with all 4 White's coils available at the time. I took it to about a half dozen challenging sites and quickly decided that was enough. I got an MXT again in May because I knew I wanted to have it's performance abilities for certain sites I work, and for my pending detecting trip.
I keep a 5" EXcelerator coil mounted almost full time, and in open areas I can opt for the stock 950, 12½" EXcelerator or 14" EXcelerator. About 90+% of the time I am hunting in very trashy environments and I prefer smaller coils, keeping a 5.3 BullsEye on my XLT as well.
I know I read about some DFX users who really like them, and that's fine. There is no such thing as a 'perfect' detector. That's why I maintain a stable of at least theee detectors in order to take advantage of their strengths based upon the site's challenges.
The slow-motion, quick-response of the MXT, combined with the excellent autotracking circuitry, external knobs for quick adjustment, and depth of detection make it a "must have" in my personal arsenal.
