The sledge hammer is used to generate seismic waves (P-waves or S-waves) at the surface. Equipped with a piezo trigger element, it sends a precise timing signal directly to the seismograph, ensuring accurate time breaks. This makes it an excellent choice for shallow downhole surveys — delivering reliable results at depths of up to 100 m.

The vibrator source ElViS VII 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 refection seismic surveys on paved roads and for urban areas. A wheelbarrow allows the movement of the source along the seismic line.

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.
