There is described a high precision blasting delay system for non-electric activation of blasting-charges at a pre-set time. The system includes a watertight plastic container which contains a base with fastening rails and contact supports, the base being divided into compartments in which an electronic circuit is placed that performs control of the entire system, sensors that detect the activation of the shock tube, an electric detonator that detonates the sequence of the blasting-charge, a shock tube that transports the switched on detonation signal, a micro-switch that connects the electric energy source with the circuit, and an impact channeling device that holds the shock tube and guides the expansive wave towards the impact sensor.
