[QUOTE="blisters, post: 164473, member: 4992"] The sdc electronics couldn't do gpr. Gpr requires measurements taken 1000s of times faster than a metal detector. The shallower you go the faster still plus a MT uses a coil to transmit a magnetic field in to the ground while a gpr uses an antenna to transmit a radio wave. A mt measures induced magnetic field decay while the gpr measures reflected wave times. Jon [/QUOTE]
