Advantages of shock tube. Five MDI blasting caps are available which replace the M6 electric and M7 Non-electric blasting cap. High-strength blasting caps. A red flag is attached 1 meter from the blasting cap and a yellow flag 2 meters from the blasting cap. May be initiated utilizing fuse igniter or match.
Yellow bands indicate calibrated one-minute time intervals.
Burn time will increase with altitude and colder temperatures. Each blasting cap has delay elements to allow for staged detonations. Low-strength blasting caps. Used as a relay device to transmit a shock tube detonation impulse from an initiator to a high strength-blasting cap. Low strength blasting caps cannot reliably set off explosives.
