The DT-NH831 night vision binoculars feature an ergonomic design, effective imaging and long operating time. It is compatible with digital cameras and camcorders.
The DT-NH831 has a convenient binocular form factor for binocular observation in adverse lighting conditions and at night. The integrated, sensitive gallium arsenide (GaAs) photocathode generates a more crystalline, detailed image than second-generation thermal imagers. Detects objects from a distance of 250-300 meters.
The anodized aluminum body is resistant to shock, water and dust (IP65). It effectively protects the electronics, allowing it to operate in a wide temperature range from -40°C to +50°C. At the same time, it weighs only 605 g.
