Universal aiming point
The sight uses a 2 MOA green dot aim ing point. The green LED provides a higher contrast of the aiming point against the background of the environment, this color is better perceived by humans and at the same time the least tiring to the eyes.
Battery saving system
The device'simpressive runtime of up to 50,000 hours is due to the Shake Awake system , which automatically turns off the LED when there is no activity and the device goes into sleep mode. Re-activating the aiming mark requires only moving the weapon. The user can independently define the time after which the sleep mode is activated.

Such functionality allows changing the battery without removing the collimator from the weapon, as is the case with models with the battery located on the underside.
Two mounts
The set includes two Picatinny/Weaver rail mount s : a high one (1/3 co-witness) intended mainly for carbines and a low one recommended for shotguns.
