Elvis III S8/P8 | Surface vibrator source

The Vibrator Source ElViS III is used to generate P- or S-wave sweep signals. The source consists of a moving mass driven by a cascaded linear motor. The source is fully cased. An adjustable pneumatic suspension ensures a maximum release of seismic energy under different surface conditions. The source is most suitable for reflection seismic surveys on paved roads and for urban areas.
