Holosun HE509-RD Features

• * Solar Failsafe
• The Holosun HE509 Red Dot Sight uses Solar Failsafe technology to power the optic providing the shooter or operator with a consistent, and very reliable point of aim. Another feature you simply don’t expect with a lithium powered optic sight such as this is you don’t have to worry about turning it on or forgetting to turn it off.
• Shake Awake Technology
• The Holosun Red Dot Sight uses patented Shake Awake™ technology which senses motion to power the sight on and off. In addition, Holosun manufactured this little sucker with a brain that “recalls” your last setting and makes sure you don’t lose those customized settings once the sight system turns off.
• Battery Life
• Worried about battery life? The Holosun HE509 Red Dot Sight offers up to 20,000 hours of battery life. Simply put, we don’t think you’re going to have to worry about buying a new battery for this sight system for quite a while. All versions of the Holosun Red Dot Sight system are projected from the same LED, so you don’t have to worry about having to re-zero when changing reticles.
• The revolutionary patent pending ACSS Vulcan reticle provides a large circle guiding the eyes towards the 10 MOA center chevron, eliminating one of the biggest challenges for shooters new to slide mounted red dots. If you are off center, a portion of this outer circle will appear in the window to give you an instant reference on how to get centered. The circle phases out of the sight window completely when the center chevron is properly aligned in the sight window. This patent-pending reticle function significantly improves sight acquisition. It takes the common frustration of hunting for the center reticle out of the equation. Don’t need the circle? It can be easily deactivated to extend the battery even further.
