MARY Smart is a single-channel, 24-bit ADC, low self-noise (<1 μV) electromagnetic receiver operated from a smartphone. The scope of the MARY Smart receivers includes engineering, environmental, prospecting and exploration studies. It is intended for carrying out electrical exploration works by the following methods and their various modifications:
- Vertical electrical sounding (VES)
- Frequency electromagnetic soundings (FEMS)
- Electrical profiling (EP)
- Natural fields (EP)
