Taking their place among Nikon‘s flagship series, the 10×30 Monarch HG Binoculars are an alternative to larger 42mm models for those who need to move fast and light, but don’t want to compromise performance. Like all HG models, the 10×30 is engineered with a powerful magnification for observing distant subjects such as large game or marker buoys and complementary technologies that produce an optic built to perform in all light conditions and survive the harshest environments.

First of these technologies is the use of lead- and arsenic-free extra-low dispersion (ED) glass in the lens elements to correct chromatic and spherical aberrations. Next are phase-corrected and dielectric-coated roof prisms, which further limit internal light loss and interference and improve image contrast. The optical path is fully multicoated with anti-reflection coatings, which increase light transmission, image contrast, and sharpness and provide true color rendition. Finally is the use of Nikon’s field-flattener lens system, which eliminates the distortion common at the edges of the lenses, producing crisp details along the far periphery of the wide field of view. This all translates to bright and clear, high-contrast images with accurate color across the spacious field of view with a reduced appearance of visible hand shake—especially at low light such as early morning and late evening, and under heavily overcast skies.

The chassis is built with a short bridge design, which provides more gripping surface and helps to reduce the overall weight—this is especially important on an optic that measures just 4.7″ in length. Made to survive use outdoors, the optical tubes are nitrogen filled and O-ring sealed to make them not only fogproof when moving between extreme temperature changes, but also waterproof and submersible. The exterior has textured, rubberized panels that protect against knocks and drops and offers a slip-resistant grip for sure handling in cold and wet conditions. Nikon includes tethered objective lens covers to ensure they cannot be lost easily and are ready for use at a moment’s notice.

Engineered for durability and performance, the 30mm Monarch HG binoculars are an excellent choice for those who are looking to reduce the size and weight of their binoculars without compromising performance.
