Three years of development and field trials have resulted in the proven SparkMaster system from ASL. This sophisticated initiator is said to meet the needs of explosive engineers requiring a reliable shocktube-based system. The SparkMaster has been designed to suit an array of site conditions and can provide reliability even in challenging environments. The solid-state, ergonomically-designed unit is portable, robust, highly-visible and weighs just 700grammes. It can be operated while still inside its weather-proof carrying case, and its charge is provided by a set of replaceable batteries with a life of around 500 firings. An LED warns when the batteries should be renewed. For firing, the blaster inserts the magnetic safety key and holds it in place with one hand. When the unit displays a green light, the blaster presses the firing button with the other hand and the unit sends a spark into the shocktube to initiate the blast.
