Characteristics

NB adopts high-pixel sensors and 12μm ≤20mK NETD thermal sensitivity, presenting outstanding image clarity even in low visibility environments. In the comparison test with the same high-end models, NB performed better in foggy and low visibility conditions, providing clearer and more detailed images.
NB is equipped with an automatic zeroing function, which can automatically calibrate the aiming system according to environmental changes to ensure consistent accuracy. This function does not require manual adjustment, significantly saving time and effort. It enables hunters and shooters to achieve stable and reliable shooting performance whether hunting in the wild or training at the shooting range.
The NB series is compatible with dual types of batteries (18500 and 18650), among which the 18650 battery can provide up to 7 hours of battery life. Supports flexible battery replacement to ensure continuous operation of the device, allowing you to focus on your goals without worrying about battery power issues.
The brand-new one-click gun calibration technology of the NB series makes precision never so simple. Easy to operate, accurate and error-free, every aim is full of confidence.
