Seismic sources
Geo Alps can use a beam for the generation of SH-waves. The 70 kg beam is encased at the ends by steel plates. The beam coupling at the ground is improved either by several spikes driven into the ground or by loading the axle load of the vehicle wheels. Using an 8 kg sledge hammer to strike alternately both ends , the beam produces SH-wave trains of opposite polarities, which are used for the identification of the refracted s-wave arrival times.

Seismic sources Weight dropper FFWD-GX II
Free fall of a 360 kg hammer from a height of 4 m with a tool assembled on an IVECO Daily truck.
The tool is equipped with a locking mechanism preventing the rebound of the weight when it hits the base plate.
Under favourable conditions investigation depths reached 4500m.
Weight dropper BISON EWG III
The fall of a 250 kg steel piston is accelerated by elastic rubber slings. The drop height is 0.8 m. The tool is assembled on a 4×4 GAZ truck.
Under favourable conditions investigation depths reached 3000m.
Weight dropper VAKIMPAK The weight is a 50 kg hammer connected to an anvil in an airtight cylinder. The fall is accelerated by the vacuum produced when the hammer is lifted. The drop height is 1.6m, the total weight is 750 kg.
Under favourable conditions investigation depths reached 900m.
Weight droppper SAWD
The weight of 15 kg is accelerated by a spring. The SAWD is equipped with a small hydraulic weight lifting unit driven by an electric motor. In order to save battery power the lifting of the weight can be assisted manually. Very handy in rough terrain, the total weight is 150 kg.

Seismic source
Elvis III system
Is a compact P or S wave vibratory source is ideal for high resolution seismic reflection surveys. The newly available Sweep Freq vibrator control software developed by Geomatrix, means that you can control the operation of both Geodes and the vibrator from the same PC, and have total control over your sweep parameters and output amplitude, please refer to Sweep Freq page for further details. Elvis brings the control of data quality previously the realm of seismic reflection surveys for the oil industry in to the hands of the engineering geophysicists.
