I really enjoy reading all the posts comparing the DFX and xlt, of course there are those who tried the DFX and failed, or possibly had a faulty machine. There are those who say there are no differences
well there are! Enough for you to go from a xlt to a DFX...that is up to you! How about instead of me trying to battle with the xlt users I just list 10 FACTS about improvements the DFX has that are not even debatable:
FROM MY NOTES WHEN I CHOSE DFX>>>
1.The dfx is a multi frequency machine giving you the ability to operate in either 3MHz or 15 MHz or both!<Choice is good!
2. Ground filters- the dfx has from 2 to 6 ground filters, the xlt four. The added filters allow for better adjustment in highly mineralized soil.
3. Adjustable Sweep speed- the DFX has an adjustable sweep speed, the xlt is fixed. This allows for adjusting from a slow sweep in a high trash area to a fast sweep in an open field with less trash.
4.Microprocessor- The microprocessor on the DFX is set at 14.32 MHz, this allows for a much quicker screen response than the xlt, which is set at 6.75 MHz.
5. Back light- with the great adjust ability of the dfx you can even store the back light in custom programs, the xlt nope again!
6. New LCD technology on DFX- -4 to 158 degrees F, xlt>32 to 122. This helps with the darkening and fading.
7.tone i.d.- thanks to the digital software the DFX actually contains 191 tones!!! One for each vdi number.
8. The DFX can be balanced to both negative minerals and positive minerals at the same time thanks to the dual frequency operation. The xlt can not<this creates falsing when going in and out of salt water.
9. 3khz better for copper/silver coins
10. 15khz better for low conductivity targets such as gold!
I'm not knocking the XLT, but the advancements in technology should be noted! Obviously there were advances made with the DFX. Should you buy one? I think that is your choice. I remember reading Understanding the DFX by Jimmy Sierra, in it he lists quite a few more upgrades. I just thought I would list the first ten off my list.
