good move and you are right about the depth of the Minelab. You can go over those worked out spots of yours and pull some oldies that were out of reach of the DFX. I have done this at several spots and I am still learning the machine. The DFX throws way too many false signals at you when you run it wide open, but I still like it around cellar holes, so I'll keep that machine and maybe trade the XS for an SE in the spring. Keep your eye on the Depot and Findmall classifieds. Some dealer just posted a new SE with the stock and the 7.5" coil for around $1200, with some other extras too. Good luck and keep in touch for a spring hunt. Ron
