Cross Hole Energizer P/S
CHE - PASI srl (PASI)
Specially designed for small-scale cross-hole surveys, this compact hammer can be used to generate both P and S waves.The hammer can be downloaded using the steel cable and clamped to the requested depth by a pneumatic clamping system manually controlled by a lever from the surface; simply pushing up the steel cable to execute the first shot, the trigger installed on the energizer will start the acquisition for the “P/S”. After that you will have to drop the mass to make the acquisition with inverse polarity.
