GF6 - Seismo-Electric Survey Instrument
The GF6 seismo-electric survey instrument is designed specifically for detecting electrical signals generated by the passage of seismic impulses through layered rocks, sediments and soils. Its design is portable, rugged and simple. The remarkably high signal to noise ratios achieved with the patented design means that productivities are high; up to twenty water well or oil well sites or more can be surveyed by one operator in a day of work.
