The PVS31 Gen2/Gen3 NVB Binocular Night Vision Goggles redefine dual-eye night vision excellence, tailored for professionals who require immersive, long-lasting performance in demanding environments. As a head-mounted night vision goggle (HMNVG), it leverages Gen2+ and Gen3 imaging technology paired with a P45 fluorescent screen, delivering superior resolution, enhanced contrast, and a 50°±2° wide field of view—all while maintaining a lightweight design (≤450g without batteries). Unlike single alternatives, the PVS31 binocular night vision offers stereoscopic vision, reducing eye strain during prolonged use and improving depth perception for critical tasks. With a versatile power supply system (CR123A/AA battery + AAx4 battery box) and 15–75 hours of working time, it’s built for extended missions, from security patrols to search-and-rescue operations. The PVS31 night vision goggles combine ergonomic design, rugged durability, and intelligent safety features, making them a top choice for users who refuse to compromise on performance.

The PVS31 binocular night vision device sets itself apart with dual-eye optics, providing natural stereoscopic vision that enhances depth perception—a critical advantage for tasks like navigating uneven terrain, identifying distant objects, or coordinating team movements. The P45 fluorescent screen (superior to P43 in light amplification) delivers brighter, more detailed images, while optical distortion ≤2% ensures edge-to-edge clarity. With 1x±0.05x magnification, it preserves natural spatial awareness, making it easy to transition between night and low-light conditions.
Unlike single-battery night vision tools, the PVS31 Gen2/Gen3 goggles feature a dual-power system: a built-in compartment for 1 CR123A or AA battery, plus an included AAx4 battery box for extended use. This flexibility ensures up to 75 hours of working time (with the battery box), eliminating the need for frequent recharging during missions. The manual brightness gain adjustment lets users optimize image quality based on ambient light, from starlight to dimly lit urban areas.
Safety is paramount in the PVS31 night vision goggles, which include lateral rollover detection (in addition to flip-up detection) that automatically powers off the device when tilted sideways or flipped up—preventing accidental activation and preserving battery. Other safety features include low-voltage alarm (alerting users to low power) and strong light protection (shielding internal sensors from sudden bright lights, like headlights or flashlights). The IP65 waterproof rating and -40℃~+50℃ operating temperature range ensure reliability in extreme weather.
Engineered for head-mounted comfort, the PVS31 ergonomic night vision goggles feature an adjustable head mount that fits most users, distributing weight evenly to reduce fatigue during long shifts. The durable, impact-resistant housing is built to withstand rough handling, while the compact dimensions (105mmx105mmx90mm) ensure a low profile for discrete operations. The included eyecups provide a comfortable seal against light leakage, and four lens caps (two per eye) protect the optical elements from damage. The dual-battery design adds versatility, allowing users to switch between compact single-battery use (for mobility) and extended battery box use (for long missions)—a key advantage over fixed-power night vision tools.
Security teams rely on the PVS31 binocular night vision goggles for 24/7 surveillance of large areas, such as industrial sites, campuses, or event venues. The stereoscopic vision improves object recognition at a distance, while the long battery life supports 8+ hour shifts without recharging. The IP65 rating ensures performance in rain, fog, or dust.
Outdoor guides and marine operators benefit from the PVS31 head-mounted night vision to navigate trails, rivers, or coastal waters after dark. The depth perception from dual-eye optics prevents missteps on uneven terrain or collisions with obstacles, while the wide FOV tracks group members or watercraft. The battery box option is ideal for multi-day expeditions.
In search-and-rescue operations, the PVS31 Gen2/Gen3 device is a lifesaver. The stereoscopic vision helps locate missing persons in dense foliage or remote areas, while the extended battery life (up to 75 hours) supports prolonged searches. The lightweight design and adjustable head mount keep rescuers agile, even during strenuous activity.
For law enforcement training or tactical exercises (within legal limits), the PVS31 night vision goggles deliver the clarity and durability needed for high-stakes scenarios. The lateral rollover detection and strong light protection enhance safety, while the dual-power system ensures uninterrupted performance during long training sessions.
Battery life ranges from 15 hours (single CR123A/AA battery) to 75 hours (with the AAx4 battery box), offering flexible runtime for different mission lengths.
Yes—the +2SD~-6SD diopter adjustment is available for both eyes, allowing users to customize focus individually and ensure clear vision for users with asymmetrical visual acuity.
Absolutely—the included head mount features adjustable straps and padding, fitting most adult head sizes comfortably and distributing weight evenly to reduce fatigue during prolonged use.
The P45 screen offers higher light amplification and better contrast than standard screens (like P43), delivering brighter, more detailed images in ultra-low-light conditions—critical for long-distance observation.
No—while it has an IP65 waterproof rating (protected against water jets and dust), it is not designed for submersion. Avoid underwater use to prevent damage to internal components.
