What is the low-frequency option for and how much does it cost?
Deeper investigation can be done with low frequencies. The standard Stratagem has a lowest frequency of 10 Hz. The low-frequency option goes two orders of magnitude lower at 0.1 Hz. If the depth of investigation is beyond the standard Stratagem it can often be reached with the low-frequency option. Acquisition requires a set of magnetic coils designed for the low-frequency band, a set of porous-pot electrodes with low-frequency buffers, and low-frequency sensor calibration files.
