SHAKE AWAKE

Shake Awake Technology is a standard feature on all current model Holosun optics and serves to extend battery life by deactivating the optic’s LED while not in use. A highly sensitive motion sensor works to detect motion keeping the LED powered on during use. This allows for duty or concealed carry with seamless operation throughout your day or shift. At the end of your day or shift when your firearm is stored, the motion sensor will detect a motionlessness state and after 10 minutes (default setting) Shake Awake Technology powers the LED off until motion is again detected. Shake Awake offers settings from 10 minutes to 12 hours depending on the model and can be deactivated altogether if preferred. The slightest touch of the optic instantly reactivates the LED so your Holosun optic is ready when needed.

MULTILAYER REFLECTIVE GLASS

Holosun’s use of Grade 5 Titanium in certain Elite category optics and laser devices results in unparalleled strength and durability. Holosun Grade 5 Titanium has more than double the tensile strength and has five-times the fatigue strength of 7075 Aluminum. Grade 5 Titanium is also able to withstand the corrosiveness of seawater making Holosun Titanium model optics and lasers suitable for use in maritime environments.

MULTILAYER COATINGS

Holosun red dot sights and magnifiers are manufactured using optical glass with multilayer coatings applied to facilitate maximum light transmission and wear resistance while reducing glare.
