R-XYZ-CG, 3-components analog down-hole receivers

The R-XYZ-CG is a borehole hammer for inverse VSP and cross-hole seismic surveys. The seismic signals are conveyed to ground by means of clamping wedges. The hammer is designed as motor-driven accelerated weight drop. The model is equipped with electric motors and trigger sensor.
