ESP2 Seismic Energizer is used to “energize” soil to better determine its nature as well as its stratigraphy through seismic prospection. System is made by two steel cylinders that, once detonation is triggered, move one inside the other thereby energizing underlying soil. Its use is extremely simple and safe for operator since trigger is operated in remote by external unit which grants explosion due to embedded rechargeable battery. Bayonet clutch makes cartridge replacement quick and easy.
