GDI GeoExaminer 3D Metal Detector Ground Radar - Pro Version

GDI GeoExaminer 3D Metal Detector Ground Radar Geophysical – uses ground probes for resistivity data collection. For large metal detection, void location with graphical separation of metal targets from voids and other geological features. Geophysical system comes with 4 probes as standard or optional 22 probes. Magnetometer – a super sensitive 80 cm. gradiometer probe reveals soil magnetic field disturbances caused by voids, ferrous metals, foundations, walls. Metal detector – portable for quick scan, pinpointing and selective rejection of non-valuable metal targets. Geo Examiner locator processes digitally the signal from pairs of transmitting & receiving probes continuously. When using probes, the signal is electrical, induced direct into the ground. GPR ground radars and VLF metal detectors at the opposite have electromagnetic wave type of signal that is transmitting aerial, towards the ground, therefore loses in penetration ability occur as it is absorbed from ground m
