This module is for Pyros that fire on 6 Volts.
The module is encased in a plastic shell for protection. It has connections for the battery and for the fitting of a pyrotechnic. A sensitive microphone is also fitted. When a shot is fired from a cap gun the microphone picks up the sound and immediately pulses the module which immediately sends current to the pyrotechnic and explodes it. You can use any type of pyro with the module. For example you could use a 'Bullet Hit' to break a vase or kill a toy Teddy Bear etc.
