GEPARD-8
BROADBAND MULTIFUNCTION EM RECEIVER GEPARD-8
Description:
All-in-One multifunction geophysical EM receiver GEPARD-8 is intended for sensitive and accurate registration of electrical and magnetic fields in wide frequency range, both in natural source and control source modes and wide exploration depth intervals. System works with variety of sensors, including grounded and non-grounded electric lines, high frequency and long period induction coil magnetic sensors, fluxgate magnetometers, aircoils and airloops. Flexible configuration of electrical and magnetic channels allows to increase productivity in the field and collect data sets for several methods and sites with one geometrical field layout.
