Product in production
The Time Delay Firing Device (TDFD) is employed by Special Forces and other units to place charges on high value targets with set times that will allow safe departure for the area and precision coordination of timed missions. The TDFD is a small, lightweight, electronic timing device with a flash explosive output for initiating a user attached M7 blasting cap. It is inherently more safe, reliable, and accurate than the family of six M1 Chemical pencils that it replaces. It is capable of being set in the field for time delays ranging from five minutes to 30 days in one minute increments. Training is provided with the aid of an M45 classroom Training Kit.
