Not a tough to learn as usually claimed.
Depth: It's difficult to truly judge how deep a detector will detect, many things have to be taken into accout, but overall this machine will find 95% of the coins that are there to be found. My one dislike is that the DFX tends to break up fairly badly on deep targets, the Signagraph will also jump around. If the audio is somewhat repeatable with some bars to the right, dig the target. You might be surprised.
Pinpointing: The DFX is an outstanding pinpointer with a concentric coil provided you have ratchet pinpointing OFF. The VCO also helps to determine the depth accurately. Note that the VCO on and DC SENS up will make the detector squeal even though the target may be over 4 inches deep.
Signagraph: Helpful, but can be misleading in some instances. It wants to display iron along with a good target in highly mineralized soil. Overall, a good tool. Listen to it, use the graph as an assistant.
Discrimination: Very good, although setting discrimination with the menu can be a chore. Block edit is still confusing to get right. Small gripe but a grip nonetheless.
Dual frequency: I've found the DFX does a better job when 1 frequency is used in some conditions. Tailor the mode to the targets you intend to find. IE 3KHz coins and 15KHz in the jewelery department.
Battery life: For what this detector does, it's quite excellent.
Build and Customer Support: Second to none for both. My DFX has been used and abused. It's held up extremely well considering it's a computer on a stick. When severely abused, White's has always replaced or repaired no questions asked. Simply outstanding customer support.
GB offset - Makes significant difference on small deep targets. A setting not discussed, but a very powerful option.
Discrimination - Compared to other detectors I rank this one near the top.
Bells and whistles - if you get to know them, they can be a real advantage.
Build quality and balance.
Adjustable filter settings - you'll know what I'm talking about when you hit a trashy patch, notching the machine to 2 filters makes it quite snappy.
Backlight - Very useful
Key shortcuts - Quick adjustments
DC Phase - Good way to gauge mineralization
Susceptible to interference
Need more EEPROM slots for custom programs
Out of the box, performance is abysmal.
Inter-related settings can really increase need for ibuprofen. If in doubt, reload the program.
Very choppy on deeper targets compared to some other machines I've used.
That's about it. I hope you were able to get something out of the review. It's by no means a perfect machine, but it can come very close with a bit of practice and knowing how to tweak the controls properly. This thing is suitably deep for most hunts, this statement is also subjective.

MY NEW DFX HAS MADE THE LAST 6 WEEKS MY BEST EVER!!
I had read reviews on nearly every land machine and narrowed my choice down to a few models. The bottom line was that the best posts in all of the forums came from DFX users. The only complaint I read about the DFX was that it takes some people a while to master.
I finally got mine in late March 2008, and let me tell you I LOVE IT. I read the manual 3 times before it arrived and after a few outings I felt comfortable with all 44 of the adjustable controls. If you are not comfortable with all of the adjustments there are also 6 preset controls for "turn and go" detecting.
You can control just about anything on the DFX, including things that are usually preset at the factory like sweep speed and recovery time. You also have the option of frequency ( High frequency for gold, low for silver and copper) or you can choose Dual frequency which is great for all around hunting. The dual frequency also makes the DFX a great beach hunting machine. Most detectors have trouble going from dry sand to wet sand, but the DFX does so with no problems.
The VDI Display has 195 "notches" which gives you accurate target ID. You can even tell a silver quarter from clad!!! The VDI also allows you to notch out pulltabs without worrying about notching out jewelry and gold.
Here are some of my results from the DFX from April and early May. All of the finds are from two sites I have detected many times before using other metal detectors:
24 Eighteenth and early nineteenth century "Flat" Buttons;
A few silver Rosies and a Mercury Dime;
My first silver "War Nickel" (I got one in pocket change the next day..weird!)
An 1809 Half Cent;
An 1801 Draped Bust Large Cent;
A 1942 Walking Liberty Half Dollar
These 6 weeks with the DFX have given me my best finds in 7 years of detecting. It is simply an amazing machine!

For those who say the DFX is complicated I'm guessing they have problems using the television remote. The DFX is as much a turn-on-and-hunt detector as any I've seen. I used the factory coin/jewelry program for the first 3 months and found coins easily at 8" missed by other top of the line detectors.
To this day I am still pulling old coins from our city park where other detectors have quit producing. Some are not that deep but the other detectors failed to respond. I know this because on our club hunts we have each member check each signal before we dig, and most of the other detectors fail to detect them at all.
The DFX is susceptible to EMI(electromagnetic interference) so leave your cell phone at home. I found 75% of my interference was from my own cell phone.
In it's factory programs the depth of the DFX isn't all that impressive, although I got 8-9" consistently, but the dual frequency does a great job of pulling keepers out of "worked out" areas. Once you get comfortable with the DFX's characteristics just a few simple adjustment turns it into a deep seeking monster.
The DFX is as simple or complicated as you want to make it. For those who are afraid they can not run the DFX, you really need to get your hands on one to try and you'll see it couldn't be simpler unless it had 1 knob.

Dfx SO SO
I bumped pre amp gain up and ac sens and it didn't seem to help at all.
My tesero seems to match it in detecting depth and I think the Tesero sounds off better on targets too.
But in all fairness my top of the line minelab wouldn't go deep either.
I hunt really trashy places so maybe thats why.

Some uses that might give other makes some problems.
2. Very useful tone id, and Signagraph info.
3. Very wide range of ground mineral adjustments.
4. Adjustable to swing fast with good depth.
5. Very good discrimination at surprising depths.
6. Wide range of Very good loops.

Like everything it takes a little practice. Also, I'd suggest buying the supporting materials from White's (book & DVD) plus the Jeff Foster Book "Digging Deeper with the DFX"...
