"Fire in the hole!" followed with a push on a blasting machine button and a loud bang. A procedure that is strictly regulated and requires special training areas and paperwork. But not with EST-DET. Same effect with less headache.
EST-DET uses the electrical impulse of a blasting machine to fire a NATO 7.62 blank cartridge. The device is reusable and is equipped with PDFS (Passive Direct Firing System) that enables the use of line testers.
