If you have a suitable PC, you will need your shotgun, a suitable room, and you will need to purchase a DryFire Home Pack. The Dryfire Home Pack contains everything else you need for one person. The Home Pack includes the following: the main simulator unit a gun assembly (which includes the muzzle laser insert, the trigger box, and a trigger switch), an AC/DC converter to power the simulator unit, a serial cable to connect the simulator unit to one of your PC’s unused serial ports (also called COM ports), and the Dryfire software.
