Shake Awake™

     Another great piece of technology created by Holosun is Shake Awake™. This great feature allows an optic to automatically go to sleep when the unit has not detected any type of movement or vibration in a specific amount of time that is programmable by the operator. However, once the unit senses movement, it will automatically turn itself on and recall the last brightness that was used. This great feature helps promote battery life further and insures the unit is on and ready when you need it!
