This high performance passive night vision monocular uses a single, MX10160(A) Generation III intensifier tube to provide crisp, clear images under the darkest conditions. This is the lightest, mass produced monocular on the market, yet it's waterproof to 66 feet and will run on a single Lithium 123 battery. Designed as a versatile system, the monocular can be helmet-mounted, weapon-mounted, or installed onto camera lenses.
