The ATN PS31-3W is a compact dual-tube night vision binocular system built for operators who need serious performance without the weight penalty. Unlike heavier legacy designs, this US-made device combines a remarkably small footprint with Gen 3 auto-gated image intensifier tubes—the result of direct feedback from field operators who demanded better resolution, less head-borne burden, and improved situational awareness in low-light and no-light environments. Whether you're conducting tactical operations, conducting advanced training, or running demanding field work, the PS31-3W delivers the optical capability and ergonomic design that separate purpose-built gear from generic alternatives.

The standout feature is the independently pivoting tube housings, which let you run true binocular configuration for depth perception and easier navigation of terrain and obstacles, or flip to monocular mode for quick transitions between night vision and weapon-mounted optics in mixed lighting. The tubes themselves are auto-gain capable, automatically adjusting brightness as conditions change—no manual fiddling in the moment. Built-in flood-type IR illuminator means you're not dependent on external IR sources, and the bright-light cut-off protects your eyes when you transition to lit areas. The 51-degree field of view keeps you aware of your surroundings without tunnel vision.

Durability is a given: the matte-black polycarbonate housing is corrosion-resistant and rated IP65 waterproof, and it pivots flat against your helmet when stowed, lowering your overall profile and protecting the optics. Run it on a single CR123 battery for 60 hours, or step up to the optional battery pack for 300 hours of operation. Diopter adjustment from -5 to +5 accommodates different vision, and focus ranges from 0.25 yard to infinity. Made in the USA with a three-year warranty backing your investment.
