Ron,
I have both detectors and like them both.
The DFX will do better at the beach due to the 2 frequencies. I took both to the beach here in NJ and the DFX worked better in the wet sand. The DFX is NOT hard to set up to start using. If you are going to hunt the older home sites for coins, get the 5.3 coil.
This weekend, I lent my brother my DFX with the 5.3 coil...I used my XL Pro with the 4x6 DD shooter. I had my brother set up with the Coin/Jewelry program with only 1 modification...pre amp gain to 3. We hunted an old fair ground site.
I found 1 wheat penny and a few clad coins.
He found 4 wheat pennies, a 1880 IH, a 1944 Merc dime and a 1912 silver Canadian dime. He hit the right spots...I didn't. We hunted about an hour before the rain came down. He has used my DFX several times, mostly on the beach with some programs I have stored. This was the first land hunt with the DFX in a while, so the pre-set program with pre-amp to 3 seemed the easiest to use. Worked well for him. The first time out with the Super 12 coil on the DFX at the beach, my brother got a nice 10K ring with diamonds and garnets. Needless to say, the DFX is his pal and he will not use any other unit I have...and I have several different ones.
Either detector is great...the DFX IS easy to set up...it's when you start teaking it to try to get the most out of it that you have to learn it's nuances. The XL Pro has less tweaking to it to get max depth. Plus it has several great modes including an easy to use all metal with ID. The XL Pro meter is dead on, but the DFX Signagraph is no slouch either.
To me, you cannot go wrong with either, but the XL Pro is simpler...problem is they are hard to find.
Good luck on whatever you purchase.
