Description
The GNG-GF31 is a helmet mountable thermal fusion night vision binocular system that combines a 640×512 thermal imaging sensor for detection and a 1″ low light digital night vision goggles sensor for navigation and observation, as well as target positioning function. This device offers a real time fusion of low light and thermal imagery with no misalignment with a high refresh rate and very low latency and it can be used in the day or night. It can be connected to a helmet or run as a handheld unit. Features:- OLED Micro Display- Binocular Stereoscopic Vision- Rain proof- Long battery life- 100Hz High Refresh Rate- High Dynamic Range- Orienteering Compass- Day and Night use Only available for shipping to the United States. Free UPS shipping with insurance and signature will be required for delivery! International orders will not be accepted. There is also a monocular variant from ADNV called the GF20.
The GF31 is a next-generation digital night-vision thermal fusion binocular engineered for serious operators who demand performance without compromise. Built around dual 1-inch high-sensitivity imaging sensors with ultra-low-light capability down to 0.00005 lux and a 640 x 512 12μm thermal sensor, the GF31 delivers clear, real-time imagery and heat detection in the darkest conditions where lesser systems fail.
With a crisp 800×600 OLED display and high-speed 50Hz / 100Hz frame rates, the GF31 provides smooth, low-latency imaging for confident movement and rapid target acquisition. Its wide 50° field of view and true 1× magnification preserve natural depth perception and situational awareness in dynamic environments.
Designed for mission-critical use, the GF31 thermal fusion goggles operates for over 75 hours in low-power mode, and is housed in a rugged IP67-rated aluminum alloy chassis built to withstand harsh operational conditions. Fully compatible with standard Wilcox mounting systems, it integrates seamlessly into modern tactical setups.
This isn’t entry-level equipment.
The GF31 is trusted by professionals for tactical training, security operations, and demanding night missions where reliability matters.
GF31 — digital night vision and thermal performance, without compromise.
