"The NGS/PVS-7 is widely recognized for its unsurpassed dependability and ergonomic design. This U.S. Military-grade night vision goggle system has repeatedly proven its worth in combat, and is the highest-quality AN/PVS-7 B/D system on the market. The PVS-7 can be outfitted with high-performance Gen 2+ and Gen 3 image intensifier tubes (available in Green phosphor or P45 white phosphor). The PVS-7 is equipped with Automatic Brightness Control (ABC) to adjust image brightness in changing light conditions to maintain image definition and clarity. The builtin infrared illuminator provides a light source beyond the visible spectrum to enable the user to operate in complete darkness without being detected. Additionally, the PVS-7 has a bright light cut-off feature to protect the image tube from sources of intense light, and a flip-up shut-off feature that can be used with the optional helmet mount system. The PVS-7 has two LED indicators in the eyepiece for the IR illuminator on and low battery indicator. Lightweight, tough, and versatile, the PVS-7 can be handheld, or mounted to the user’s head/helmet. It is compatible with afocal magnifier lenses for superior long-range viewing."
