Orica says its uni tronic blast box BB310R is a remote blasting solution. The remote blast box can be placed in proximity to the blast pattern and can communicate via radio modem to the firing control box, which can be positioned at a point of safety up to 6,500 feet from the blast pattern, providing increased safety for personnel and equipment. The unit is compatible with the company’s existing uni tronic Scanner 110 and uni tronic Scanner 120 equipment and is equipped with a Bluetooth module allowing easy download of scanned detonator details.
