3 MOA Red Dot Reticle
The 3 MOA red dot reticle provides a clear, precise aiming point without unnecessary visual clutter. Combined with the 1x optical system and unlimited eye relief, it allows the shooter to acquire the aiming point quickly while maintaining a broad field of view.
The 11 brightness settings allow the red dot to be adjusted to suit different lighting conditions. The Shake Awake system is designed to activate the sight when movement is detected, keeping the ZeroTech red dot ready when required.

Long Battery Life and Shake Awake Technology
Battery performance is a key feature of the ZeroTech Thrive HD reflex sight, with a maximum stated battery life of up to 50,000 hours. The side-loading CR2032 battery compartment means the battery can be replaced without removing the entire sight.
Auto Sleep helps conserve battery power when the sight is not being used, while the motion-sensor Auto ON function brings the red dot back into operation when movement is detected.
Rugged Reflex Sight Construction
Built for use in demanding conditions, the Thrive HD is shockproof, waterproof and fog proof. Its compact construction measures approximately 45mm long and 28mm high without the mount, while weighing around 88 grams with the battery installed.
The supplied moulded rubber cover provides additional protection when the ZeroTech reflex sight is not in use.
Clear HD Optics
The Thrive HD uses multi-coated optics with a specially developed anti-reflective (AR) lens coating designed to minimise image distortion. The 28mm x 20mm objective lens provides a clear sight picture through the compact reflex optic.
Low and High Mount Options
The ZeroTech Thrive HD 1×28 red dot sight is available with either a Low or High Picatinny-compatible mount, allowing the sight height to be selected according to the intended setup and firearm configuration.
