The clear choice for use in light-polluted areas. - By combining better-than-military standard night vision imaging with field-ready toughness, the ARES 4-3P is the clear choice for better-than-MIL. STD. performance in light polluted areas. The 3P Pinnacle image intensifier tube and 100% waterproof, field-tough optics offer exceptional performance in any light conditions. The fast, infrared-sensitive optics and military-standard Gen 3 image tube make for easy target acquisition, whether you're a professional operator or a dedicated varmint hunter. The red-on-green reticle system provides optimal contrast against dark and light targets alike, while 1/6 MOA windage and elevation adjustments let you really dial in with precision accuracy. A detachable IR illuminator provides invisible light when natural light is scarce. The industry-leading ITT Pinnacle image tubes utilize an auto-gated power supply, providing truly outstanding performance in high-light or light-polluted areas, such as urban environments. The Pinnacle tube with gated power supply minimizes any "halo" effects. "Halo" is often associated with using night vision devices in an urban area where random street lights are often an issue with early generation night vision devices.
