Inadvertent firing is almost impossible because of recessed spring-loaded controls requiring two controls to be depressed simultaneously and in sequence for firing. Depriming occurs automatically if the device is not fired. Despite the high energy output there is no danger to the operator touching the output terminals or conductors even in wet conditions. Any combination of detonator and cable can be used. The Elex-7 has an inhibit circuit to check that the total load is less than 400 ohms. This ensures against misfiring as well as against electric shock.
