One Shot is a compact hand-held pyro firing system capable of firing a maximum of 2 ignitors in series.
Features: Arm key switch, continuity test LED, fire button.
 
Powered by 1x 9V battery.

NB: The key switch system used on all our firing systems has become obsolete so we will be changing to a new system. This will not affect any systems already supplied, and we will still be able to provide replacement keys, just not the switches. As normal, a key will be supplied with all new controllers.
