Washingtonian, I see you have a DFX and a CTX.... so do I..... I went from the DFX to a Fisher F75, love that one too... Got a great deal in Dec on a used (Like new) CTX , couldn't pass it up for 1/2 price.... So , this year is a learning curve with the VDI numbers being so different than the Whites.... but, I like the depth I'm getting , quite a machine... I have been detecting 29 years, soo use to the Garrett, Whites and Fisher number system... big difference... but, I love the 2 different number system...
