Does 403R Have Shake Awake?
Yes, the Holosun 403R, like many models in Holosun's lineup, features the "Shake Awake" technology. This innovative feature automatically activates the red dot when it detects motion, ensuring the optic is ready whenever you need it. Conversely, it conservatively saves power by entering a sleep mode when the sight is not in motion for a set period. This contributes significantly to the long battery life characteristic of Holosun optics, allowing users to rely on their sights being operational even if they haven't adjusted them for an extended time.
