The Dfx, ordered will be here in Chicago on Wednesday. Hopefully I can get in 10-15 trips before ground freezes here. Some may say the xlt is the same. This is not true. I spoke directly to a White's technician models are very similar but the duel frequencies give the dfx an impressive edge that allows for better more defined detection. He also said when asked about spending the extra $200, that is up to you, do you want to find what the others are leaving behind...>>>DFX I also asked about the coils, he said to go with the 5.3, over the 4x6. I will post after i use, if I don't freeze to death! Thanks for everyone's help, Gregg.
