Abstract

A hand-held shot tube detonator including a primer and shot tube holder removably mounted on a firing pin body having a flash guard movable between extended and retracted positions. The flash guard is retracted to permit mounting of the holder on the body and is then extended to surround the holder to channel the flash and explosive gases away from the operator when the detonator is fired.
