No, have not...but just attached a "Sunray"pin pointer to my DFX. Used it the first time yesterday and what a eye opening experience..This thing will have you digging FAR less dirt to recover finds..about golf ball holes, as it responds directly over finds and the depth is very good. With the DFX, you just hit a toggle switch and then the pinpointer runs off the detector electronics. You didn't say what kind of a machine you have, but if one of these is availible..get it, you'll really like the way it works..
