High Resolution Airborne Geophysics


Geotech's proprietary ZTEM is an innovative new airborne AFMAG (Audio-Frequency Magnetics) system for plane-wave frequency domain electromagnetic surveying, which can be operated by a helicopter or a fixed wing aircraft. Utilizing the naturally occurring or passive EM fields from worldwide thunderstorm activity of the Earth as the source of transmitted energy, this revolutionary technology has a proprietary receiver design and advanced digital electronics and signal processing. This allows for low noise levels and exceptional resolution and unparalleled depth penetration, well-suited to mapping deeply buried, porphyry hosted and structurally controlled target types. ZTEM is a standalone available exclusively from Geotech with over 250,000 line-kilometres flown in under 4 years.
