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.

LS-24 | Landstreamer

The Landstreamer LS-24 is used to record P-, S- or surface waves. It consists of a number of horizontally or vertically oriented sensors mounted on sledges which are attached to a robust belt. The belt can be hooked to a vehicle and moved along the profile. A landstreamer is used to collect a large volume of seismic data in a short time. The landstreamer is suitable for MASW or reflection seismic applications especially on paved ground.
