SOURCE

OHM’s fourth generation electromagnetic source,DASI IV, sets the industry standard for useable output power at multiple, discrete frequencies and for precise phase control, both of which are crucial for accurate detection and imaging of subsurface resistivity contrasts. DASI IV features a complete suite of diagnostic and QC data sampled at a frequency that ensures high fidelity monitoring of the source waveform and critical safety factors. >more

RECEIVERS

OHM’s fourth generation electromagnetic (EM) receivers, EFMALS III, set the industry standard for ultra sensitive, ultra low-noise electronics and precise instrument response calibration. EFMALS III receiver units are unique in offering variable receiver dipole lengths for different environmental noise conditions, as well as compact, light-weight design for ease of handling. >more
