As dough says, the Deus can be used in Culpeper under certain conditions, but no VLF machine should be your primary choice in Culpeper. Because the area has been pounded by detectorists for years, most "surface" finds are deep and the very highly mineralized soil limits vlf depth. PI machines such as the TDI, GPX, and ATX are the go to machines because they are affected less by mineralization and can punch deeper. However, they are basically dig it all machines that don't use discrimination. Some, like the GPX, have a fairly reliable iron blanking circuit as a telltale for likely ferrous targets. The problem is that circuit makes them pretty much useless in thick iron situations. In that case, the Deus, though not deep, separates well and penetrates just enough into the mineraluzed soil to perhaps eek out some of the shallower keepers hiding amongst the iron. The Deus also works well in the wooded areas where mineraluzation levels are lower than in the heavily plowed fields. Deus also makes a great discriminating "pinpointer on steroids" to cherry pick non-ferrous keepers out of the dirt piles removed from trash pits and huts uncovered in fields that contained long-term CW field encampments.
