I took the XT pro out last Sunday for couple of hours on a permission that was hard to find target on I started off in field one and after I switched to field 2 and was on full sensitivity reactive on 3 I found the detector was very stable I had a Crotal Bell 17th Century this was found at a depth of 12 inches in clay soil conditions my next find was a Medieval Pilgrim Ampula this was found at a depth of 10 inches down both targets gave a strong signal I was surprised how good the XT pro performed.
