Night vision goggles D221H PRO are a professional high-tech device designed to perform various activities in low-light conditions, which require to orient at short distances, closed spaces and to have free hands.
D221H PRO have a classic binocular arrangement with high quality stereoscopic image that ensures increase in distance of detection and recognition up to 1.3 - 1.5 times, compared with the devices where pseudo binocular scheme is applied. The construction of the goggles allows to use the tubes gen. 2+/3 of the world leading manufacturers.
The device is made in waterproof version, has a possibility of filling with nitrogen, built-in dehydration cartridge prevents defogging of lenses inside in case of unforeseen depressurization.
