(57) A system for commercial blasting operations includes at least one commercial blasting system element in the form of a translocation monitoring unit (TMU), configured to reside in a borehole, which is configured to be couplable to, coupled to or incorporated in a wireless initiation device that is configured for commercial blasting. The TMU includes: an inertial measurement unit (IMU) configured to measure spatial displacement of the IMU based on one or more movement sensors of (internal to) the IMU; and/or an externallygenerated localization signal reception unit configured wirelessly receive one or more types of externally-generated localization signals transmitted by one or more localization signal sources disposed external to the TMU and external to the wireless initiation device. The system includes an electronic processing unit and memory configured to evaluate spatial displacement, and to control the wireless initiation
