Been along time since I have used a White's detector, I just got a nice Classic ID with the 950 and the 600 Blue Max coils. I have been know to wheel & deal but am going t give the Classic ID a good workout as soon as it warms up enough. I did take it out in my yard to play around with, I was surprised how accurate the TID was, it correctly displayed each coin at the detectors depth limit. Steve.
