Sent my 70 to Minelab for erratic beeping and falsing issues. I received it yesterday and seen where they had replaced the PC Board, Control Panel, and the front panel control box. I cant wait to get it out and find something. All in all, they gave me two new coils and pretty much a new box. This past weekend was beatiful and I didnt have a machine, today there is really heavy layer of frost and cold........just my luck!!
