Description Industry's First Magnetic Charging Cover: Osight introduces a pioneering magnetic charging cover featuring a battery display that reveals the precise battery levels for both the cover and the optic, making uncertainty certain. (70,000+ hours runtime on lowest mode, 17+ days on the brightest mode, extended to 70+ days with the charging cover.) 3 MOA in Large Window: Boasting a 0.94 x 0.85-inch lens, this optic ensures precise targeting even amidst recoil. The 3 MOA dot stands out clearly for quick and accurate dot acquisition. Unwavering Zero: Following a rigorous 10,000-round field test, Osight maintains zero calibration successfully, never lose your accuracy. Motion & Light Sensor: Turns off automatically after 10 minutes of inactivity, wakes it up in an instant. The auto-sensing mode chooses the best brightness for you, with 10 daylight levels and 2 night levels in manual mode and lockout mode, catering comprehensively to all usage scenarios. Most Common Footprint: By adopting the most common industry-standard mounting footprint (Ruggedized Miniature Reflex, 407c/507c footprint) for optic cuts, Osight ensures versatility and ease of integration. ✔ Olight Osight consists of an optic and a charging cover. It's the industry’s first charging cover with a percentage battery display, allowing you to monitor the battery level of both the cover and optic anytime. In addition, you can also check the battery status with the tri-color indicator on the optic. ✔ Both the cover and the optic are powered by a rechargeable high-capacity battery. A fully charged cover can charge a low battery optic three times. ✔ On a single charge, the optic itself can last over 70,000 hours on its lowest mode. Even at its brightest setting, it can continuously run for over 17 days and this duration can be extended to over 70 days with the support of a fully charged charging cover. ✔ The 3 MOA dot is clear and easy to locate, ensuring swift and precise dot acquisition. The optic can be easily zeroed with windage and elevation adjustments. And it has successfully maintained zero during a 10,000-round test. ✔ It features manual mode, lockout mode and auto sensing mode. With its motion sensor function, you can wake the optic in an instant, and it will turn off automatically after 10 minutes of inactivity.
