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.

QC spectrograms from field data clearly illustrate the signal fidelity and precise frequency control achievable with the DASI IV energy source.
