Yup, the DBP2010 is an excelent PI, the best i ever seen or built, with 1m x1m coil, this gun could be found up to good 6 feet in carbonate sand, in forrest soil 3 or 4 feet could be a problem. There was a Italian/ Avsto-Hungarian front line (12 havy battles) and stuff like this is common, literaly tons of this stuff are everywhere, could be as deep as 15 feet or even more. Some areas use to be literally covered with dead bodies, cannon lines, deep storage werhouses, shelters, trunches....... If i take my Miner4 with small probe (4 feet only) i get a signal on every square meter (3 feet). And there is unexploded material to watch out.... (and even today can still pritty much explode when not handled properly, exidents are common).
